Creating a Backup/Recovery/Dump - Upgrading, Modifying and Unlocking

Forum:
If this specific question is in another thread, please forgive me and redirect me.
If not, any instruction would be greatly appreciated.
Equipment:
Visual Land, Prestige 7
Model # VL - 107
ICS 4.0.3
Baseband 1.0
Kernel 3.0.8+
Build # 86F5-D1-H1-MO1-1718.20120327
Objective:
To create a backup/recovery img/dump of the existing stock ROM, without having to add "clockwork", "cynogen", etc...
Software on Hand:
Windows 7
Livesuit 1.09
Virtualbox
Ubuntu via Virtual Machine
Please detail everything and speak to me as if I were a little child...
Thanks in advance!

I'm sure you have a recovery on your phone that's a tool to create a backup of stock rom on your sdcard
enter recovery (usually volup+menu or something like that) or you have some options in phone menus to backup device
that will create a set of img files on sdcard that's your backup also you can restore your phone from this backup if you get in trouble
so it's a good idea to have one !

Can this be done with ADB?

That's a negative...
The tablet is completely stock - straight from the box.
In turn, I do not have a recovery (such as clockwork, cyanogen, etc.) that would allow me to make a backup img.
And, I would like to start/learn by making a backup img without such a recovery; i'm assuming this requires using ADB.
Therefore, I need detailed instructions on how to create said backup img...
I have not found any settings or options in the tablet itself that performs this function either.

I understand now this is a tablet so it's common problem for some
well you have to find a way to root device to get access to system files then use a rom dumping tool just take a look here or here
nobody can tell you for sure how to do that this is device specific I do not know to much about that particular tablet just try

I just got this tablet today, and it's rooted out of the box.
Not sure if that helps you, but I wanted to contribute if I could.

Recovery for Galaxy Ace 2 - i8160
Hi,
Any chance of a simple recovery for the Galaxy Ace2 i8160 ?

VL107 Update Down To 4.0.3/4.0.4
Hello,
I've been trying to figure out how to change my VL-107's OS, and a Recognized Contributor pointed me to this thread.
I've downloaded LiveSuit, but I can't figure out how to make it work. If at all possible, I need two things: an .img file for 4.0.3 or 4.0.4, and instructions on how to apply this update via command prompt or a program that utilizes command prompt.
I have Windows 8.1, my VL-107 (Visual Land Prestige 7), and LiveSuit (which I'd really rather not use).
The only experience I have in flashing involved using command prompt, and I'm much more comfortable doing this than relying on a program to do everything "behind the scenes". Otherwise, I would also be willing to put an .img file on my tablet's "SD card" and apply the update through Recovery mode.

[Q] DHD android most beginner know how

Finally I got my DHD, the time where everything is rolling out, from perm root, to recovery...
The good thing, I'm very happy with my DHD, the bad thing, I'm not familiar yet with android system.
I revised a lot of android and DHD threads, and I faced many new terminologies that belong to android where I like to have explanation for each.
Please let me understand the following issues the beginner way, allowing me to maybe make a simple guide answers for most new android users coming from winmo.
I-General questions:
1-DHD should be multitouch. Then why games like Gameloft are not multitouch like on ipod or iphone?
2-What are the buttons combinations for the different operations like hard reset & boot loader?
3-I read that android can’t share internet via USB for those with no WIFI at home or office. As I knew it’s due to ad hoc issue so it's impossible to get internet via USB cable from desktop. When I plugged my DHD, I choose internet pass through and I got internet on my DHD, is it a new feature implemented in DHD only, or is it a 2.2 update that will work on other devices?
4-Winmo gives the choice to install applications on either the device or SD card. Android have nothing like this, so when I install applications, where do they go, and is there a workaround to put everything on SD card, or maybe give choice to where to install?
5-My DHD comes with an 8 GB mini SD card where there are some folders and files on it. Are they necessary to run the system, what if I replaced this card with another formatted one, what will happen, or what if I format this card?
II-System info:
1-Baseband version (is it like the radio in winmo?)
2-Kernel version (is it one kernel for the entire device? Does it updates like rom or like radio?) e.g. (kAmMa's OC&GOV&BFS Kernel - Performance and Stability. Is this a rom or just kernel that will update some parts of the rom without losing data on the device?)
3-Build number (is this the firmware?) e.g. (i have 1.32.405.3 CLxxxxxx release-keys, what does release keys means?)
4-Software number (or this is the firmware?)
III-OTA ACE with radio:
1-OTA (is it a rom, does it mean over the air, if yes what does that mean? Can we update OTA with no root?)
2-ACE
On winmo (HD2), I know HSPL will let me unlock ISPL so I can install any custom or cooked rom, languages and applications...
For android, as far as I know there is no one click solution. From what I understand to do everything in android with no restrictions u need to do the followings:
IV-How to root Desire HD install h-boot (S-Off) and Clockwork recovery?
Please identify which one is just a process that we do it once in order to unlock it, which is a boot loader run application and which one is an android application:
1-Root (is it what gives access to the root folders of the system that maybe are hidden by default or encrypted?)
2-Hboot
3-S-off (is it security off? if yes, it is security off for what? installing applications, or read write to some encrypted partitions?)
4-Clockwork (is it something necessary to do in order to install custom rom, no adds, backup and so on, or is it something totally independent and related only to unlock the speed of the CPU where you can leave it intact if you won’t play with the CPU speed?)
5-Recovery (from what I understand it seems that recovery is a system shell command like dos or more like bios for android but named as recovery, what can we do with the recovery other than recovering the device?)
6-Recovery image (is it a rom backed on the form of image and provided by developers, so we can install it directly on the device using only the recovery shell?)
V-More things to know about:
1-What is adb?
2-What is busybox?
2-What is fast boot?
3-What is eMMC write?
4-What is ext2 or ext4 (is it like the partition type of the SD card based on UNIX system? if yes, why should we change or modify this ext)
5-Rom manager (is it a desktop pc application or android device application? is it something like I can put the RUU file of the rom on my SD card and using the rom manager I can install the rom from there, nothing more nothing less?)

Congratulations. You win the "most questions asked in a single post" award.
Sent from my Desire HD using XDA App
That is a ridiculous amount of questions, and the thread is in completely the wrong area of the forum. I'm sure you'd find the answer to pretty much all your questions if you looked hard enough, but to answer the one about multi-touch. It is multi touch and all the games I've played from your example 'Gameloft' are multi-touch, so I don't know what you're smoking buddy, but ease off.
1. Inb4 "search".
2. Wrong forum.
3. No really, try searching. At least 30% of that is googleable.
Sent from my Desire HD using XDA App
Ok guys, thank you all for your replies, and yes I knew that a war and flames will go on here, but seriously if you think this is ridiculous or newbie or most dumb questions, do not turn the way of the thread or flame me, my intentions are to make this as a one small guide for most new androids functions, it's not a bad thing to do, in fact I will learn as much as other new users here, no one is asked to answer all those ridiculous questions, just answer what you know about, guys please take it seriously and easy, saying look harder will not help the thread, it may help me personaly, but be sure that I did a lot of search, and it will not hurt to put everything in one place, and as you can see, I answered most of the questions up to what I gathered, you can correct me about my answers, put your thoughts or not answer at all, but please be constructive here, and if you all think that i'm in the wrong forum, or asking too much, or asking ridiculous questions, please moderator feel free to do what you think is better for the forum.
Sorry guys for bothering you. Thank you for your response.
N.B.: just to be more accurate, I tried the prince of persia pre installed on the phone by the dealer, and it was not multi touch, so you cant walk and use any of the right actions at same time.
@vuedesprit: Good thread, and thanks for taking all the criticism from the more experienced users.
@all chimers chiming the "use search, wrong forum" tune: c'mon guys, there's at least 2 of us reading this thread going, it's about time all this information got consolidated into one place! The easier it is to find this information, the easier it would be for more of us to get engaged in the process and thus further development, enhancement and adoption.
While our "friendly" mod is doing his best to keep the forums clean, they're as fragmented as ever and from time-to-time, it becomes necessary to consolidate the information into a single thread. I'm sure most of you started some place too and remember the time not so long ago when it was difficult to find even the most basic info? I think by sharing your knowledge, you will gain a much better following and the platform will gain much better adoption.
My 2 cents worth anyways...I've had my DHD for 3 days now and I too am struggling to perform even the most basic tasks.
We really need a questions and answers sub forum
Fair enough, maybe my first comment was a bit rash, but I didn't mean to appear rude. I shall try to answer some questions here:
GENERAL.
1. From my own experience all games advertised as multitouch are exactly that. I don't know about the version of PoP that you have installed from carrier, but I do find that odd.
2. Hard reset is a little perverse with the new "fastboot" hibernation feature that HTC have implemented. You have to go to MENU>SETTINGS>APPLICATIONS and disable "fastboot" (this is where confusion may arise as this is not the bootloader fastboot that allows images to be flashed)!! Now when you hold down the power button and get the option to power off, you will properly power off the phone. Next if you hold "VOLUME DOWN" and "POWER" buttons you will reboot into HBoot, from here the VOLUME UP/DOWN keys navigate the menu and POWER selects menu options.
3. Not sure about this one.
4. Since the release of FROYO you can go to MENU>SETTINGS>APPLICATIONS>MANAGE APPLICATIONS then select any app and move to either SD or to phone memory.
5. The folders on the SD card are mostly generated by the phone when you first insert it. The user guide and HTC sync software are there to move onto your PC for safe keeping. If you insert a freshly formatted SD card, the phone will make fresh folders such as DCIM for pictures, etc...
SYSTEM INFO.
1. Baseband is radio software.
2. Kernel is the linux kernel that is running below Android, this can be updated separately from the main ROM, radio etc. HOWEVER CAUTION IS ADVISED AS CERTAIN KERNELS WILL NEED NEW MODULES FOR HARDWARE TO FUNCTION CORRECTLY as you will see from the wifi modules bundled with the OC kernels.
3. Build number pertains to HTC's internal software version classification (some are built specific for carriers) they are generally released via RUU (ROM Update Utility aimed at windows) or OTA (Over The Air update received on phone [again sometimes carrier specific]). Release keys pertains to the fact that the firmware has been signed by HTC (I think).
4. Software number, basically as above.
OTA ACE with Radio.
1. As Above.
2. ACE: internal HTC name for Desire HD (also reportedly known as "SPADE")
ROOT DESIRE HD ETC.
Most of what you have written is pretty much correct.
MORE THINGS TO KNOW ABOUT.
1. http://developer.android.com/guide/developing/tools/adb.html
2. http://www.busybox.net/about.html
3. http://android-dls.com/wiki/index.php?title=Fastboot
4. eMMC write basically means that you can write to the internal phone (normally protected) memory such as /SYSTEM, this is what S-OFF allows you to do whenever you want. However, the modules that allow the ENG HBoot image to be flashed are what really accomplish this in the first place so theoretically you could just run that module every time you wanted to write to /SYSTEM but that would become very tedious very quickly. I can't really explain further, as I don't have the knowledge.
5. EXT2 or EXT4 are filesystem structures just like FAT, FAT16, FAT32, NTFS, HFS+ etc, EXT4 is newer and more advanced than EXT2 and therefore is more efficient. (kinda general but you get the idea. NEWER=BETTER)
6. ROM manager, find this in the android market, it is free, you install it on your phone and with the addition of clockworkmod it gives you the ability of flashing ROMs etc. USE WITH CAUTION.
I hope that this answers or clarifies most of what you have asked or said, please feel free to cut and paste any of this info into your first post so that we can actually consolidate this.
P.S. I too am a complete android noob and this is my first android phone, I have picked this info up mainly from this forum so all credit for information goes to XDA-DEVELOPERS.COM and not me.
Cheers,
Dok

1-DHD should be multitouch. Then why games like Gameloft are not multitouch like on ipod or iphone?
Click to expand...
Click to collapse
an application must support multitouch and other gestures. eg, opera doesnt support multitouch (ie you cant zoom in and out) but the browser that comes with the DHD does.
2-What are the buttons combinations for the different operations like hard reset & boot loader?
Click to expand...
Click to collapse
boot loader = turn phone off. then, volume down + power on.
4-Winmo gives the choice to install applications on either the device or SD card. Android have nothing like this, so when I install applications, where do they go, and is there a workaround to put everything on SD card, or maybe give choice to where to install?
Click to expand...
Click to collapse
application must support running from /sdcard. When you install an app go to settings -> Applications -> manage applications. From here you can uninstall or move apps to the sdcard. Bear in mind if you have not rooted your phone you may not be able to uninstall some apps (eg amazon reader).
5-My DHD comes with an 8 GB mini SD card where there are some folders and files on it. Are they necessary to run the system, what if I replaced this card with another formatted one, what will happen, or what if I format this card?
Click to expand...
Click to collapse
some application data is stored on your sdcard, and apps are stored here if you have moved them by using the steps above. if you change sd cards this info is unavailable to the app but the app should still work. any settings you had need to be redone.
2-Kernel version (is it one kernel for the entire device? Does it updates like rom or like radio?) e.g. (kAmMa's OC&GOV&BFS Kernel - Performance and Stability. Is this a rom or just kernel that will update some parts of the rom without losing data on the device?)
Click to expand...
Click to collapse
the kernel is not part of a rom or the radio. It is stored in the boot partition in the emmc (where fastboot(aka hboot)/splash images/boot(kernel)/recovery/ are all stored). It is generally included with but not required by a custom rom. ie, a custom rom builder may choose to include a specific kernel with his rom but it is not mandatory.
1-OTA (is it a rom, does it mean over the air, if yes what does that mean? Can we update OTA with no root?)
Click to expand...

yes, you can do OTA HTC updates. but, there are no custom (non signed) updates delivered OTA. An unrooted rom will not be able to flash non signed updates (or roms).

there is a good thread here - http://forum.xda-developers.com/showthread.php?t=841076.
Please identify which one is just a process that we do it once in order to unlock it, which is a boot loader run application and which one is an android application:
1-Root (is it what gives access to the root folders of the system that maybe are hidden by default or encrypted?)
Click to expand...
Click to collapse
android application. eg, visionary+.
2-Hboot
Click to expand...
Click to collapse
hboot is also known as bootloader. it is the white screen with the skating androids when you do the volume-down + power combination when switching on your phone.
3-S-off (is it security off? if yes, it is security off for what? installing applications, or read write to some encrypted partitions?)
Click to expand...
Click to collapse
s-off stands for security off. you can check the status by doing the volume-down + power combo. At the top it will either say s-on or s-off. If you have s-on then your bootloader (hboot), boot (kernel) /system (android) and recovery (eg clockworkmod) partitions are all read only.
4-Clockwork (is it something necessary to do in order to install custom rom, no adds, backup and so on, or is it something totally independent and related only to unlock the speed of the CPU where you can leave it intact if you won’t play with the CPU speed?)
Click to expand...
Click to collapse
clock work is the recovery partition. you have 3 possible options before loading android when you do the volume-down + power on combo. hboot, then either fastboot or recovery. fastboot and recovery are both ways to flash images to your phone although through different ways (fastboot uses the fastboot command on your pc to send the image, recovery uses .zip's on your /sdcard). clockworkmod is a custom recovery image which you need to flash after achieving s-off. it's also where nandroid backups can be done. if you select recovery before doing this you will get the phone + red triangle icon. thats the stock recovery. the clockworkmod is the green menu selection one.
5-Recovery (from what I understand it seems that recovery is a system shell command like dos or more like bios for android but named as recovery, what can we do with the recovery other than recovering the device?)

see above.
6-Recovery image (is it a rom backed on the form of image and provided by developers, so we can install it directly on the device using only the recovery shell?)
Click to expand...
Click to collapse
clockwork mod can backup your phone's partitions (boot/userdata/system) so that if you mess up installing a rom you have a way to recover. this is known as a nandroid backup.
1-What is adb?
Click to expand...
Click to collapse
adb is android debug something. It is a way to send commands to the android operation system from your pc (either windows or linux). eg, you can run a single command, or run a shell (terminal session). it is part of the android sdk under tools.
2-What is busybox?
Click to expand...
Click to collapse
busybox is a single executable whihc runs under the android OS that provides standard linux commands (eg, ls, rm, cd) to any application. it is so that a script writer does not need to know the partiticular rom you have and then cater for it, but only that you have a certain version of busybox. eg, busybox 1.17.1 provides the same commands whether it is on a leedroid rom or a cyanogen rom.
2-What is fast boot?
Click to expand...
Click to collapse
fastboot is a way to flash images to your phone. it is accessed via hboot. you need the fastboot exe from the htc developer site. it can flash the boot (kernel), recovery (eg clockworkmod) and the radio (i think).
3-What is eMMC write?
Click to expand...
Click to collapse
the emmc is the storage device which holds hboot, fastboot, recovery, /system, /userdata and (not sure about this one) radio. when you switch on your phone the emmc is read-only due to the s-on flag being set by hboot. you need to flash the engineering hboot which does not set s-on when you switch your phone on.
4-What is ext2 or ext4 (is it like the partition type of the SD card based on UNIX system? if yes, why should we change or modify this ext)
Click to expand...
Click to collapse
ext2 and ext4 are linux file system types. eg, windows is ntfs, linux has ext2/3/4 and others.
5-Rom manager (is it a desktop pc application or android device application? is it something like I can put the RUU file of the rom on my SD card and using the rom manager I can install the rom from there, nothing more nothing less?)
Click to expand...
Click to collapse
rom manager is an android app available on the market place to help with the flashing process. it can flash recovery partitions (as long as your phone is s-off), make nandroid backups (as long as you have clockworkmod & s-off). it can also flash custom roms. it does not flash these from within the android OS (afaik) but it will reboot into (not sure on this one) the recovery partition and leaves it instructions to flash a particular rom.
This thread is amazing!!
We had a lot threads like this in the HTC Blackstone Board of pocketpc.ch....
Hope to get more threads like this in every device category....
Thumbs up
Perhaps Threadstarter can write the answers in the first post...??

[RECOVERY]Samsung Galaxy W i8150 RZRecovery

I'm very happy to announce, that a developer raidzero from rootzwiki forum, has made us a fully working recovery for Samsung Galaxy w i8150!
You can download it from here:
DOWNLOAD
TEMPORARY LINK .... USE THIS IF FIRST ONE DOESN'T WORK
THANKS TO andynroid FOR PROVIDING LINKS!
Flashing recovery is very simple, all you need is root access on your phone, and adb on computer. You just copy downloaded recovery on internal sdcard. Then disconect phone from copmuter. Make sure that USB debugging is on. Now connect it again but don't connect phone memory (computer shouldn't see sdcard and internal memory in Windows explorer), open command prompt and got directory where adb is installed, now enter this:
Code:
adb shell
$su
#dd if=/sdcard/RZR-2.1.4-ancora-rec.img of=/dev/block/mmcblk0p13
This is all. Now turn off phone and turnd it on like this: hold Volume Up + Home + Power button, when Samsung sign appears relese power button but still hold other two, until recovery is loaded. Bamm you are in, and ready to flash something, or backup ! Expolre the recovery, it has a lot of options, you can even choose what color of menus you want .
I would like to thanks raidzero again for all his effort he made! And also big thanks to arco68,for much need informations he provided!
We can now expect, that when developing his recovery and adding new goodies, this recovery will follow others!
great news!! Thanks for your effort!
Has anyone had a chance to test the Recovery?
Will this work on the Samsung Exhibit II?
thanks mate.downloading now. just in case it needs to be recovered. after this we would see custom roms developed by our developers here..

I wouldn't bet that this will work on Exibith II cause every phone has different partitions.
after giving me the command you said to me reacts to: permission denied.. Whi?

Thanks again, will try this ASAP, just a few questions:
Is /dev/block/mmcblk0p13 the Recovery partition??
Is it been overwritten by the dd if.......of??
Should the original stock recovery?? be backed-up/saved first??
Is there an MD5 or anything to check file integrity:
This could be used on the Device: Android File Verifier
Can the procedure be done using Terminal Emulator on the phone?
Do I need to have stock ROM for it to work?

There are two possible reasons for this either you didn't run su command first, or you don't have rooted phone.

1. Yes /dev/block/mmcblk0p13 is recovery partition
2. It is gonna be overwritten with costum one.
3. You can back it up that you reverse dd command. Or I can upload original recovery.
4. There isn't MD5 cause noone made it , you only need MD5 file if you would like to flash this via Odin.

Thanks, gotta learn ODIN first,
btw, thanks for the ODIN d/l........installed it, but still unsure how to proceed???
I have latest Kies installed on my laptop, any reason why you do not use it?? It appears to allow back-ups and restores, also new firmware d/l.
As I am new to Samsung, and also ODIN, but does using ODIN have advantages over Kies, and is it safer to upgrade new f/w with ODIN or Kies, do you lose root, or anything else??
BTW, on the MD5 thing, for the RZR-2.1.4-ancora-rec.img
I used MD5 Checksum Tool from http://www.novirusthanks.org/product/md5-checksum-tool/
to generate the MD5.

I just think it is good security practice to check file integrity before applying on your device, as many things can happen, like data corruption, while transferring file from download on Laptop to SD card, and best to check file on device SD or Internal Storage with AFV against MD5 generated at source.........
which I did not check at source, but I am just illustrating for example!!
[BTW, lots of MD5's on rzdroid.com recovery ftp site, here, but not sure of our .img file
The above MD5 is what I got from the d/l file
Thanks again, I saw your stuff with raidzero on rootzwiki.........

Well I really don't know that is better to use Kies or Odin. If you want official and (what is supposed to be tested) firmware, tha you better use Kies (but well even with kies your phone could get bricked, I've learned that from one user here ). If you want to flash latest firmware, which sometimes is not availible on all the countries, and you can't get it from Kies fast enaught, than I suggest odin is the choice. I prefere Odin, cause I don't like official stuff .
To use Odin is very simple. You need to turn on phone with Volume Down + Home + Power. When you are prompt (on hte phone),wether to conutioue od cancle, you connect phone and computer with USB cable, and choose contuinu, now you are in download mode. Then all you have to do, to choos proper .ops file (button OPS) in odin, an proper firmware (usually you choos that under One Package button, if you have one package in tar.md5), then you wait for chekcking md5. When is checked you just click Start, and wait for stuff to happen.
Don't forget that there is a possabiltiy that something might go wrong with flashing, but it is not that big one. I suggest, that you first made full nandorid backup with recovery, if something goes wrong, you can boot you phone in recovery and restore it totaly. And one more suggestin when flashing, do it with latop(if possible), so that you have battery and power cable plugged in laptop, if electricyty goes out, that you still have battery to run laptop.
And thanks for the support you guys are showing to me, since I'm not a developer. I try really hard, to get people that are willing to help us developing better roms for our phone !

Spot on. I just need to know if it is ROM related (that I need a ROM file on my PC).
Thanks for the reply.
Hey there, just a noob question:
Where are adb drivers installed? I'm working under Windows 7.
I tried to google this and ended up here /developer.android.com/sdk/index.html
and downloaded the first two files, but I'm unsure what to do now. Thanks in advance!
Hey qzem,
Am I right, that the adb driver should be installed, when i first installed Kies?
Is your Guide How-To Install the recovery also working on my mac? I think so, or am I wrong?
Perhaps you already figured by now, I'm new to Android!
There is one more thing i can't seem to figure out:
In foreseeable future, there are hopefully some nice custom roms for the Galaxy W. Do I have to install recovery everytime i flash a new Rom? Or is it like a bios, that has nothing to do with the actual Android System?
Thanks for your help in advance

For adb, you need to download Android SDK from here. Download zip file and extract it somwhere. Than go in folder where you have extract it and run SDK Manager, from there you will install adb rivers and everything else. When you are done (it could take a while, to download and install everything), open Command promnt and follow the instrucions I've wrote in first post.

The same goes for mac users, there is also Android SDK for mac. You can install Kies before this, but you need both because kies includes drivers for this phone exactly. As far as recoverey goes, if it is not included in ROM, which you flash, I think you'll need to install it again. I hope that developers will include recovery in their roms.
Thanks so far qzem,
It seems like theres someone in your Cyanogenom-Forum-Post qzem, who is trying and willing to help making a custom rom. But he seeks for som guidance!
Perhaps someone with experience like, arco can take him under his wings!
Hi there,
i would like to thank you. Everything works like a charm.
Did the flash, tried the recovery.. and uaaaahhhh....
...i forgot to backup the original recovery!
can someone please, please upload it to somewhere??
thx.

Rooting Every Spreadtrum SC6820/SC8810 phones ! (1.5)

Hello,
In this thread I will teach you every method I had to use to root any Spreadtrum devices, Starting with the riskless ones to the reckless ones.
I have to warn you that the last root method (using ResearchDownload to load a modified system.img) may be dangerous ! (because of possible partition table changes)
The others methods are pretty safe, don't be afraid by them if you do exactly what I wrote.
Theses processors are also named SP6820 and SP8810, it's exactly the same processor, it's just some misnaming from Chinese sellers.
Theses methods do work on the newest Spreadtrum CPUs, like the SC7710 (the 3G WCDMA model), and the more powerful SC8825/SC6825 (dual core).
Why buying a Spreadtrum based phone ?
They are really cheap, and they work amazingly well ! They can play some games and emulators very well, that's unexpected for such low end devices (50$ or less)
They usually only have 256MB of RAM but despite that, they still runs well ! (I tested a lot of games and some 3D games are working flawlessly, pretty amazing) - I discovered that they are using zram (or other swap methods) to provide more RAM by compressing it when needed. That's pretty neat and really helps with such a small amount of RAM !
They are very good as a portable multimedia device, to read mails, browsing the web, play some games, mp3, videos.
As a 2G phone they are competent, but the 2G modem is not as good as the one in MTK processors. (It takes longer to load something in the same conditions)
Boot very fast, and have decent battery life. (3-4 hours of video out of a 1200 mAh battery - 5-6 hours out of a 1800 mAh)
Why you should not ?
Not true anymore, but they were extremely difficult to root in some cases.
They don't seem to be well tested ... You can have a microphone so quiet nobody will be able to ear you. But it's easy to fix as you can see here: http://forum.xda-developers.com/showthread.php?p=38731407
They don't have any form of usable 3G support. (except the SC7710 who have WCDMA 850/2100 compatibility)
They usually have only 256MB of RAM again. So that can be a problem when you are, for example, using Opera Mobile Classic with more than 3 tabs. And make the transition between apps longer.
SC6820 and SC8810 model are all using Android 2.x, even if some are marketed as Android 4.0 phone (very big and blatant lie !)
They usually use android 2.3, but some are only Android 2.2 phones ! (The fake Android 4.0.3 for instance is usually only android 2.2)
SC6825 and SC8825 seems to only have a (real this time) Android 4.0.3 firmware. 4.1 are better is often advertised, but it's again ... lies ... Android 4.0 is not really suitable for phones with only 256 MB of RAM, so SC6825/8825 phones are pretty rough on the edges. Using more than one tab on the default web browser is asking for troubles for example.
They all use the MocorDroid Firmware. It's some kind of fork of Android that use NON-Standards and sometime buggy Launchers and they often use alternative keyboards like Go Keyboard which is kind of a bad choice considering the RAM and ROM constraints on theses devices ...
The only difference between the SC6820 and the SC8810 is the support for the Chinese form of 3G.
If you don't live in china, that means this two processors are essentially the same. (Don't trust sellers, the 8810 is NOT WCDMA "3G" compatible)
Some phones with the fake Android 4.0.3 based on 2.3.5 will brick themselves nearly 2 months after you first used it. It's a really weird behavior of this early Spreadtrum firmware. So if you have this firmware, just do whatever it takes to root it, make a backup and install CWM as soon as possible to be able to recover from this possible breakage. It's only a problem with a fraction of Spreadtrum phones, but you will be very happy if you have installed CWM before encountering it ^^ (applicable only if you bought one in 2012)
A lot of fakery in the Spreadtrum scene. For example fake MTK6515/MTK6572 phones that are in fact just SC6820/SC6825 phones with a firmware modified to lie its processor ID to populars android benchmarking tools like Antutu Benchmark.
If you are searching for a 512MB RAM phone, you'd better go for an MTK(6575/6572 or better) Phone. As you will never find a real 512MB Spreadtrum phone in the jungle of lies you are looking at ...
On all model with 2.3.5 based firmware (SC6820 and SC8810 essentially), you can have a lot of problems with the SIM card detection on some sim cards. For example I can't call somebody with mine, but I can answer a call or send/receive SMS ... Very weird bug ...
This bug seems to be related on the type a sim card you have. With some their is no problem at all.
I can confirm that it's working flawlessly on SC6825 and 8825 based phones with the real 4.0.3 based firmware.
Why rooting it ?
Because a lot of them come with a lot of sh*tty softwares, including the bad launcher and keyboard.
Because they can come with a "Virus" that can send SMS messages to china (so you have to pay for unwanted international SMS cost)
I myself have this Virus on one of my phones, as of now, I haven't noticed anything unusual. Just the useless, unkillable com.android.caivs.app process eating 15 MB of RAM doing nothing. (It is a significant waste of ram on such devices)
(As of now I only seen this malware on Feiteng devices - You can share your experience with this thing down bellow)
More about CAIVS here: http://web.archive.org/web/20110812021151/http://www.cseed.cn/chinese/news/portfolio2.htm
That virus was on most of the earliest Spreadtrum phones but don't seem to be a worry nowadays. But I haven't tried any new Feiteng devices. They were so poor in quality that I will never buy feiteng again so find it by yourselves if you feel adventurous xD
How-to do that ?!
If you are lucky you will be able to root your phone by traditional means.
If you are not, you can root them by manually adding the root utilities to the ROM.
I will describe every methods that you should try in order of difficulty and risks.
Before doing any of that, go to the android setting -> applications -> Development -> Check USB Debugging.
Universal Root utilities
Theses methods are safe, and the second one is, as of now, working on every Spreadtrum phones flawlessly !
1.1 - Z4Root
Just try z4root !
http://forum.xda-developers.com/showthread.php?t=833953
z4root is a little tool to root Android 2.2 and sometime work on 2.3
It's known to work on devices with the fake Android 4.0.3 based on 2.2 and MocorDroid 2.2.2
It may work on more of them, just try, there is no risks at all.
Make sure you have at least 50 MB of available space on the /data partition before trying this. (not the SDCard, the Applications Space)
Try a temporary root to see if it works, then you can do the permanent root.
You will maybe have to try it 2 or 3 times before it works.
Even if it doesn't work, reboot the phone after this. Because it can eat your battery while running in the backgroung if it fails.
1.2 - vRoot
vRoot is a chinese tool to root many devices !
It's proved to work very well with Spreadtrum (and MTK) devices. I used it successfully on a lot of Spreadtrum devices, even the most recent ones (SC8825).
You only need a Windows Computer (I personally use it on Windows 7 32bits).
Then download it from here: http://www.mgyun.com/en/getvroot
Install it and then open it.
As of now you only need to plug your USB cable to your computer, and then click on the Root button. (you don't need to do anything else, don't touch your phone)
Once it's done and the phone rebooted you will be rooted !
The root app is some kind of custom chinese one, but it's working properly.
Don't try to replace it with SuperSU as SuperSU don't seem to work properly on Spreadtrum devices.
If you want to understand what the root app is saying, try to set the language on your device to English.
2 - Custom Firmware Flash
Please never use any custom firmware available in .pac file format ! Or at least, don't use them before doing a full backup of your current firmware !
Feiteng A7100 (only if you have the mt6515_c910_ht_en_4.0_v01 rom/firmware on it !!! If not, don't touch it, you will end up with a brick ! Or screen reversed, or other strange bugs): http://forum.xda-developers.com/showthread.php?t=2149396
If you have a Feiteng A7100 I really recommend NOT TO USE this rom ! Why ? Because it only works on a fraction of A7100, newer releases of the same phone don't use the same firmware. With this tutorial here, you can root your A7100 easily and way safer. Please go to "4-" on this tutorial to know how to root your A7100.
If you append to find some others Custom roms for spreadtrum devices, or are making one, please send me a PM, I will link them here.
3 - Fastboot to the rescue !
If every fast, simple and secure methods are not working, then this will be difficult my friend !
3.1 - Find Fasboot
First, let check if we have fastboot in your phone !
Fastboot is a little tool inside the bootloader. It's here to help you flash the firmware.
Not every Spreatrum phones have it, so let's check if you are lucky !
You can access it by powering on the phone up while holding a key.
First power off your phone.
Then hold some button like volume+
while pressing this button, press and hold down the power button.
Keep holding the two buttons until the screen light up.
You should now have something on your screen. Maybe a system diagnostic tool (a menu with a set of system tests, that's totally useless) or maybe the recovery mode (a screen with a warning sign, and now your phone is stuck here until you pull out the battery) or, and that means victory, a screen that says "Fastboot".
If you are not on fastboot, but are on the Recovery or the System Test, turn the phone off again and try another button press at boot time exactly like I said before.
This time, try the Home button if you have one, or the Volume-.
You should also try buttons combinations. Like volume up and down at the same time. Home + vol Up, etc and maybe the 3 at the same time ...
(if you just boot as if nothing was pressed, you maybe have to unplug the battery, wait for a while and put it back before powering the phone on. Theses things are also not working when the usb/charging cable is plugged in - if some keys combinations are not doing anything, it's perfectly fine, it means they don't trigger any hidden boot mode)
If nothing bring fastboot up, you have to use the Spreadtrum Debug tool "ResearchDownload" ...
So Skip to "4-" ! ^^
3.2 - Install the drivers
If you append to find Fastboot, we will have to install the PC part of it !
Like every android phone, you have to install adb and his drivers to access the Android Debug Bridge.
You can find them and learn how they work here: http://dottech.org/21534/how-to-ins...ows-computer-for-use-with-your-android-phone/
On Ubuntu or Debian Linux you just have to install them that way:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
You also have to install the phone drivers if you are using Windows:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Mirror: http://www.mediafire.com/?o9km8vl287ev24j
Then you will have to tell adb what phone to use. By that I mean adding the PCI ID to a text file to tell adb that this peripheral is compatible.
The Spreadtrum PCI ID is 0x1782
add this line to "Your user directory/.android/adb_usb.ini"
Code:
0x1782
3.3 - Using fastboot to load CWM (Clockwork Mod)
CWM work on some of theses Spreadtrum devices, most of the time, the screen is reversed, but it works !
On some phone, you will be presented with a blank screen, but CWM will work ... That will just be very difficult to navigate ... (don't bother and use another method if you append to be in this boat)
Here are the recovery images available for Spreadtrum device to my knowledge:
* http://www.mediafire.com/download.php?u6uyignmdcpillt - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?bosnfcq9n65mtc5 - i9270+
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Flashing CWM to the phone:
Linux Only: Initialize ADB:
Code:
sudo adb kill-server
sudo adb start-server
Boot your phone in fastboot mode.
Be sure your device shows up:
Code:
fastboot devices
if your device show up, it's time to flash
Code:
fastboot flash recovery recovery.img
It's flashed ! Let's reboot now.
Code:
fastboot reboot
Start on CWM, if it works, you can start to root the phone !
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, he is on the same key combination than the old useless recovery was. (Most of the time Volume- and Power)
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
3.4 - Using Fastboot to load a modified system partition image
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, flash it like that:
Code:
sudo fastboot devices
#if your device show up, it's time to flash
Code:
sudo fastboot flash system system.img
#It's flashed ... Now let's reboot with all the apprehension of the world
Code:
sudo fastboot reboot
If it boots (should boot), you will be up and rooting !
4 - Spreadtrum ResearchDownload tool to the rescue !
First, if you have fastboot, use fastboot ! It's simple, more reliable, faster. It's bottomline better !
If you don't have fastboot or can't figure out how to bring him up on your phone despite trying for about an hour. This tool will most likely work.
First, you should use Windows XP 32bits. Even real XP or in virtualbox.
It might work on windows 7 32 bits and 64 bits but you will have to tweak the system to allow installation of non signed devices drivers ...
ResearchDownload work as this:
First you start the Channelserver - This thing is here to make a bridge between the tools and the driver.
Then you start ResearchDownload.
Now you can make a full firmware flash (you should not !! It's a terrible idea !) or flash a single partition. But to do that, unfortunately, you should have a compatible set of fdl files.
Finding them on google is impossible, you have to extract them from your full firmware .pac file.
If you can't find your firmware on the Internet, you will have to try every single one you can find from others firmwares. I gathered all the fdl files I could find in a single package, so it won't be that difficult.
It's highly probable that you will find one that will work with your phone. This thing have to boot the phone and flash the Nand Flash chip. I'm pretty sure there is not a lot of different ways to do this on a single processor.
I really don't know the risks of using a wrong fdl set. But we haven't seen any risks at all yet. Some will work on your phone, others will just do nothing. You will just have to try every single one until one work.
I named the folders with the names of the phones I know working with theses. So it will be easier to find the good one. (A7100, 6500-TV, 5830, Q206 and S930 users will feel very lucky ^^)
4.1 - Learn how ResearchDownload Work
First you have to install the drivers, you can find them here:
ADB Drivers: http://www.mediafire.com/download.php?c5nf3rlhxmxhu4x
Debug Drivers: http://www.mediafire.com/download.php?2tyg0k2xp3ejgyg
Then you have to plug your phone to your computer with your micro usb cable. Your phone have to be powered on.
Be sure every pieces of hardware are detected and installed correctly.
As you can see, this phone is not just detected as an ADB device, or as a mass storage device.
It actually have an internal serial port to usb adapter !
In other words that means this processor provide a way to flash his nand very easily even if it is fully bricked. It's a rare and pretty good feature you don't see that often. In fact, most of the time you have to solder a real serial port yourself on the phone motherboard, then have to use a Serial to USB adapter to have this level of access to the hardware.
So yes, back to tutorial.
Now you will have to unplug your phone and turn it off.
You have to download the debug tools, you can download them here: http://www.mediafire.com/download.php?rngukh111vqfr8h
First you have to start the channel server, you will have to disable your firewall for this app, it's because this tool use a network protocol to communicate with the other tools.
Then open ResearchDownload.
ResearchDownload is a weird flashing utility, it can open a .pac firmware file and can make a .pac out of .img files. You also can flash .img files and that's what we will do. But unfortunately it can't make a full backup ... So be careful !
The cog logo is here to let you open a .pac file. We don't need that as we probably don't have it.
The "two cogs logo" let you configure the flash utility.
Click on this to bring a new window.
On the download settings window, click on select product then choose your type of phone. (SC8810 or SC6820, it doesn't really matters if you take the wrong one out of those two.)
Then uncheck "Select All Files" as you don't have any of theses.
You can see FDL1 and FDL2 are still checked, and you don't have those files ...
As they are needed to start the Flash utility, we will have to find them.
I came across only 3 different FDL1 files, but for theses FDL1 it seems every phone have his own FDL2.
You will have to find the ones that work for you.
Here is an archive of nearly every FDLs available: http://www.mediafire.com/download.php?c6q2gxobccv32oj
Choose one FDL1, and one FDL2 located in the same folder. (you can choose a File with a right click on the FileName blank space in front of FDL1)
Click on OK.
Then click on the "Play button" saying start download.
It may show some warning, it's not a problem.
Now, press Volume Down on your phone, then you have to plug it on the USB Port, still holding the button.
You can release the button when the flash begins.
You may have to press an other button than Volume-. Some phones are reported to use the Home Button instead.
You may also have to remove, wait a while, and reinsert the battery before holding volume- or after the flashing procedure to be able to start the phone.
If ResearchDownload shows you an error or timeout, try another set of FDLs Files. Keep trying until you find one pair that work !
If it works the flashing process should start right away. Just a millisecond after Windows have detected and initialized the device when you plugged it.
When you have the right FDLs, you can go to the next step, flashing something useful ^^ (we haven't flashed anything as of now, just been searching for a compatible flashing bios)
If your working FDLs folder does not have the name of your phone, please tell me what phone you have and what FDLs you used so I can rename them.
4.2 - Using ResearchDownload to load CWM (Clockwork Mod)
Do exactly as said before, but check the "Recovery" checkbox on Download Settings. and choose one of theses CWM images:
* http://www.mediafire.com/download.php?y2f7aaan4b00l1m - Feiteng GT-A7100 and probably more Feiteng devices.
* http://www.mediafire.com/download.php?lg7m6v49efzpnjk - 6500-TV or S560
* http://www.mediafire.com/download.php?6xn977jjsuusjan - N9300 (I9300 Clone)
* http://www.mediafire.com/download.php?d68wc334qn47tdd - S930 or N8820
* http://www.mediafire.com/download.php?xem49dy5dh99ml0 - 5830, S5830, Q5830, Q206 and GT-N9300 (maybe more)
* http://www.mediafire.com/download.php?bdl1qr7orsj4ebr - extracted from a random SC6820 that I don't remember
* http://www.mediafire.com/download.php?6g1t6057p6c8wpt - i9720+
* http://www.mediafire.com/download.php?adfwq6b5268qb58 - S9300 (SC6820A S3 Clone)
When you flashed one successfully, try to boot on recovery (Usually by holding Volume- while holding the power button until the screen light up).
If your device is not listed or the one for your device doesn't work, try them all, even if your phone is SC6820 and the recovery was made for SC8810, if none are working, we will have to flash the entire system partition, which is a lot more difficult and dangerous ...
Download this patch: http://www.mediafire.com/download.php?131nsw87afzwb5v
Put it on the root of your SD Card.
Now you will have to boot on CWM, remember, he is on the same key combination than the old useless recovery was.
You can also try this command with adb:
Code:
adb reboot recovery
Now it's the perfect time to do a full backup of your firmware with CWM, so please do so, that can come in handy. (please go to the end of this tutorial after rooting your phone to know how to make a FULL backup. CWM will only make a partial one.)
choose apply update.zip
Choose the file you have put on your sd card before
Apply it then reboot.
This update.zip have pushed everything needed to root your phone in the right place, you should be rooted now !
If you have an error like:"Can't mount /sdcard" you may have to try with another SD Card and be sure your SD Card if formated as Fat32.
4.3 - Using ResearchDownload to load a modified system partition image
Now we are in deep **** ! This can be tedious ... You will need to drink a lot of coffee, then you will probably pull your hair off, but it's possible to root every single Spreadtrum devices this way !
Please follow the instructions down bellow on how to "5 - Create a rooted system partition image"
When you have done your Rooted system partition image, reboot on Windows, then flash it like that:
Do exactly as said on the paragraph on how ResearchDownload works, but check the "System" checkbox on Download Settings, and choose your modified system.img file to flash it on the device.
As it is still not tested at all, you will have to pray some kind of Spreadtrum God and hope it will be successful ...
The first boot after the flash can be very VERY long. It's perfectly normal.
After the flash is done, please make a full backup (see bellow how you can do that), so I can make a Clockwork recovery partition working with your phone.
You may need to flush your data partition with CWM to avoid some crazy bugs after the flash. You will have theses bugs because of the partitions realignment that might occurs as a result of using a slightly different FDL set as the manufacturer.
Don't even try to do a factory settings reset before installing CWM, as I don't know what monster can lie ahead if you do a factory reset without any working recovery installed
(If your phone doesn't boot after the flash, it is possible to flush the data and cache partition with ResearchDownload. I will explain it, if needed !)
5 - Create a rooted system partition image
Please always try the CWM method first ! There is no risks at all to destroy your phone if the recovery is not working. Here we are making a new system image to flash on the system partition, this partition contain the Android operating system. I will try to explain everything as good as I can, but if you make a mistake, if you don't read my warnings, you can brick your phone very easily !
That will be difficult ... And you will have to use a Linux computer, or Linux in Virtualbox, or in a Live CD, basically you will need Linux somewhere on your computer ^^
Why ? Because we will have to preserve unix permissions on an extracted tar archive ! Trust me, you will probably brick your phone if you do that on windows ...
#Install ADB
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
#Configure ADB
Code:
mkdir ~/.android
Code:
echo 0x1782 > ~/.android/adb_usb.ini
#Start the ADB server
Code:
sudo adb kill-server
sudo adb start-server
#Just let's check just in case if your device is already rooted
Code:
adb shell su -c id
Possible answers:
uid = 0 (root) gid = 0 (root) - your phone is already rooted ! (if you haven't noticed it, it's because superuser.apk is not installed, so just push it and install it via ADB and you are rooted !)
SU: Permission denied - You are not rooted ... Good luck then !
#Now we will backup the system partition !
Code:
adb shell tar -cf /mnt/sdcard/system.tar system
Please pay attention to the errors !
There will be missing files, and we will have to add theses by ourselves after the backup to pretend to have a full backup.
Here is the archive for the known missing files: http://www.mediafire.com/download.php?fm1z5ujc75bg268
If you have more than theses:
Code:
tar: can not open 'system/etc/dbus.conf': Permission denied
tar: can not open 'system/etc/bluetooth/audio.conf': Permission denied
tar: can not open 'system/etc/bluetooth/auto_pairing.conf': Permission denied
tar: can not open 'system/etc/bluetooth/input.conf': Permission denied
tar: can not open 'system/etc/bluetooth/main.conf': Permission denied
tar: system/lost+found: Permission denied
tar: Error exit delayed from previous errors
Then you should just give up, or tell me so I can send you the missing files.
Note: Lost+found is not important, it's just a folder automatically created by Linux to collect any corrupt files.
#Now we will pull this nearly full backup to our computer. Please keep it preciously somewhere secure.
Code:
adb pull /mnt/sdcard/system.tar
#Warning, theses next steps have to be made ONLY on Linux on an ext2/3/4 partition ! Please never attempts to do this on Windows or On Linux on a FAT32 partition.
#untar the archive
Code:
sudo tar -xvpf system.tar
#now we will restore the files we have not been able to backup.
#Download this archive if you haven't done this before: http://www.mediafire.com/download.php?fm1z5ujc75bg268
#Then extract it on the same folder as you extracted your system.tar file with this command:
Code:
sudo tar -xvpf btdbus.tar
#Now it's time to add the root utilities, you can download them from here: http://www.mediafire.com/download.php?v69nm172heos17o
Code:
sudo tar -xvpf root.tar
sudo cp Superuser.apk system/app/Superuser.apk
sudo install -m 06755 su system/xbin/su
#Now we will get rid of this virus ! (the file name can be something else. Like caivs.apk, or some random numbers at the end)
Code:
sudo rm system/app/eyuSales_20121116.apk
#And now you will have to make a flashable system image with this tool, included in the root.tar archive
Code:
sudo ./mkyaffs system system.img
#Now you can reboot your phone in fastboot or use researchdownload to flash your new System image.
6 - Do a full nand backup
Here is how to do a full nand backup of your beloved Spreadtrum: http://forum.xda-developers.com/showthread.php?p=39270468
7 - Don't forget to remove to caivs Virus
When you are rooted, you can remove the Virus or any preinstalled apps using Link2SD.
I suggest you to remove everything you have preinstalled if it is available on the Google Play Store (except the keyboard or the launcher !!!). For example if you have an old version of ES File Explorer on your phone preventing you from updating it, you can remove it safely, then install the updated version from the the Play Store.
Never try to remove something that you don't know what it is !
For the Launcher or keyboard. You can remove them only if you installed a new one on the System partition and tested it successfully !

Data missing?
First of all, thanks a lot for tutorial! Unluckily there is missing the data that i should copy back into the tar and then the img-file. Could you upload the btdbus.tar and the root.tar?
Thanks again, have a nice day!

I'll try to load CWM even though at the moment I can only get into recovery. I have the exact same model as H_Bler's which is why I've been focusing more on his thread. From your description on how to access fastboot, I assume that it's the diagnostic mode when UpVol + Pwr is pressed. I never saw anything that said fastboot. The only thing unusual when I was going through the menus was I always got an error when I try the 4th or 5th option. Unfortunately, I can't really try it again because I can't access it anymore. That goes without saying the I can't work with IMG files as well.

Well the thing you have when you push up and power is the system test menu. It's located on the android system partition. It's not fastboot.
Fastboot should be something that says "Fastboot" in red letter, or something else unusual.
If you have not fastboot you should use Spreadtrum Researchdownload to flash your phone, I will write the tutorial about it soon.
I really can't link you the thread on the russian forum, first because it will probably confuse you, and also because it's spread everywhere on so many threads it's unbelievable ... That's why I'm doing this centralization work for you ^^
I will post a list of ROMS for recovery purpose. Your phone seem to be bricked. I don't know how you've done it (I really want to know what you phone is and how you've bricked it, that will help me to write the warnings necessary to avoid such cases).
I have 14 roms for Spreadtrum devices, maybe one will work for your phone.
I just want to know what your phone is ^^ Please tell the name of your phone on your posts everyone and if you know how to find it, the exact name of your firmware.
PS: I will upload the patch soon, I'm just searching for a file hosting service that will keep it up and not erasing it 2 hours after I uploaded it ^^
EDIT: Link to the update.zip for rooting you device via CWM added.
Tutorial updated: Spreadtrum debug tools method added.
It may now be possible to root even Spreadtrum devices without Fastboot mode available.
Please feel free to tell me if it works !

Question
Dear Spreadtrum Master!
Please, can you help me with this problem:
I have a Star I8160 phone with Spreadtrum 6820 and 256 MB ROM. It seems, that everything is working fine, the ROM and the phone is fast, and cool. But when i try to use the phone as a phone, i talk to the phone, and the others just only hearing pieces of my sentences. Sometimes the phone is very-very silent, i need to shout for the others to hear. I thought, that this is a microphone problem, so i replaced the microphone. But nothing changed. I had 2 phones from this type, and both produces the same fault, so i think maybe the problem will be with the ROM. What do you think, is it possible? If so, can i replace my normal rom, which is DM_BASE_12A_w12.43 (sc6820_modem) 11-02-2012?

The Master hasn't been in the past few days so I'll try to answer your issue as best I can.
Usually, the phones are designed for a specific region/country. It's possible that your ROM was built for a different one. How sure are you that the ROM which you are replacing it with will work for you? (I assume that you have a backup and you know how to load ROMs) Also, you might want to try editing the build.prop it increase/maximize reception.
To be honest, this is actually a complicated approach. From what you said, it seems that you've made other troubleshooting steps on your own. Since you really did not mention all of them I'm basing my response on what you said.
Let's try to stick to the basics first. Why did you replace the microphone in the first place? If the same issue happens with 2 other phones from this type, I don't think the mic is the problem. Also, does this mean that you can hear them fine, but they have a hard time hearing you? Have you tried using the stock sound recorder on your phone? Is it also choppy? Have you tried using Skype? You don't really have to call anyone, you just need to make a test call.
When using the device as a phone (eg. making calls, sending SMS, MMS, or connecting to the internet using EDGE or 3G), you're actually relying mostly on your carrier/service provider. How many signal bars do you get? The easiest way to test signal related issues would be by using a different SIM or using a different phone. (When you try a different phone, I suggest using a GSM one - the ones that can only make calls or do SMS.) It's highly possible that there's already something wrong with your SIM.

ElectronikHeart hasn't checked in the past few days, so I hope you don't mind me butting in.
When you say brick, does it mean that you don't even have recovery mode? If you don't, try to see if you can put CWM. Once successful, you can try to use the A7100 ROM if your original one was a mt6515_c910_ht_en_4.0_v01 rom using the update.zip

Hi,
I had the same problem with one of mine. You just have to use a diagnostic tool from Spreadtrum and adjust the microphone amplification level. I will start a thread on that subject and link it there.
It seems to be a very common problem with Spreadtrum phones, but it is, most of the time, very easy to fix.
edit: here is the link: http://forum.xda-developers.com/showthread.php?p=38731407
WARNING: Don't ever flash if you don't have a working copy of the original firmware somewhere (a complete backup that you have tested your ability to flash back) The first step to do a complete backup, if the manufacturer don't want to send you the firmware, is to successfully root your firmware)
Don't flash if you have a microphone problem, nothing good will happen, this problem is not firmware related AT ALL.

Oh god ! Why have you checked that option ^^
I may be able to dump my nv.bin file from the a7100 I just bought. (If I recall correctly, the nv.bin contain the imei so I will have to edit it to use your imei instead, imei are written in the battery compartment)
Can you try flashing it a second time entirely, It's possible that your uboot partition (what manage the early time boot operations), is not flashed properly.
Even without the nv partition you phone should be able to boot android, you will just not be able to use the phone as a phone. (make a call and everything)
Try with a better micro usb cable, Chinese ones can be very cheap and corrupt data on the way to the phone.
If your phone is still able to flash using ReasearchDownload that is.

So, you already have tested every recovery already posted ?
To make a backup of your boot.img, you will have to do a full backup manually using the Android shell. I will make a tutorial about this, and link it here.
It's pretty easy as you already rooted your phone.
When you have your backup I will, post a recovery.img file suitable to your phone.
Please keep an eye to this post. I will post the tutorial very soon.

Oh god ! Why have you checked that option ^^
I may be able to dump my nv.bin file from the a7100 I just bought. (If I recall correctly, the nv.bin contain the imei so I will have to edit it to use your imei instead, imei are written in the battery compartment)
Can you try flashing it a second time entirely, It's possible that your uboot partition (what manage the early time boot operations), is not flashed properly.
Even without the nv partition you phone should be able to boot android, you will just not be able to use the phone as a phone. (make a call and everything)
Try with a better micro usb cable, Chinese ones can be very cheap and corrupt data on the way to the phone.
If your phone is still able to flash using ReasearchDownload that is.

I already try with tree micro usb cables. when i try to flash with researchDownload it failed at nvitem (after FDL2).
can you post a link to your nv.bin to test it ?

I just bought my A7100, so you will need to wait 2 weeks for me to dump it. Maybe you should try asking to the guy who have made the rooted rom for the A7100 ?
I will, none the less, make a full backup of my phone as soon as I receive it.

[Q] FP1 - 1.6 unified storage upgrade: Problems

hi!
i installed the regulat 1.6 update to my FP1 and everything was just fine.
then I tried to install the "unified 1.6 update" which worked but the problems begun:
things I noticed:
1. backup ist not really a backup for the apps but just a way to reinstall the apps I had installed without any settings. not a fun way to find that out when reopening your apps.
2. the update to the 1.6 unifyed also messed with my SD card and deleted files and put new ones there. not something I was expecting. luckily I had a backup of the SD card.
the thing I am looking for a solution:
after merging the partitions I cannot acces the phone storage on my PC (mac osx 10.9.4). not directly as a drive. the android fil transfer tool works, but it does not have all abilities finder/explorere provides. how do I get acces to the phone storage again?
As all my settings are gone anyway I am open to reinstall the phone from scratch.

Because of the partition layout it no longer is possible to expose the internal storage as mass storage device. Adb will work but the preferred way of transferring files is using the MTP protocol.
I am not a mac user but I think you need to install some additional software.

thanks a lot, that is what I feared.
hi, i'm also have an upgrade problem: mine is that i can't upgrade at all.
i've repartitioned earlier with the app mentioned in the wiki (wiki/Fairphone_Fairphone/Guides#How_to_partition_your_Fairphone).
i've also done the steps _keesj descripes in thread "unified storage setup on re-partitioned FP1" ("Steps for "fiixing" your upgrade").
i'm having Cherry 1.6, and two 7 GB partitions.
does anyone has a solution?

thanks, i've read it again and tried _keesj's solution again, unfortunately it didn't solve my situation.
i'm a layman in this area, so probably i shoudn't haved 'played' with partitions at all (but with the app it was easy).
my previous post wasn't quite complete... i have had an unified partition before...
because of an app that didn't work, i used the repartition app again to see if that could solve the problem.
it did, but later i wondered if a wrong install in the unified sistuation was the problem... so i thought 'let's try the unified partition again'...
i thought i could simply re-use the Fairphone Updater...
so maybe i'm now having a unified partition divided in 2?
and lost the ability to ever upgrade to newer versions of the Fairphone OS?
i hope someone can help me...

Make sure you allow it to reinstall the default recovery.

how do I allow it? i didn't get the question you've got ("ROM may flash stock recovery on boot. Fix?").
i downloaded Cherry 1.6 again and chose Install, gave it SU (forever) access, it automatically restarted to the Android with the text “Installing system update…” (no progress bar), and after a few minutes it restarted and nothing is changed. After starting the Fairphone Updater again, it immediately gave the Install option again. Same after selecting the Storage Upgrader.
I also tried restoring from the recovery (default, never replaced), from sd and adb (1.6 does install, 1.3 doesn't, and 1.6 partition upgrader doesn't either, gets aborted)…

Non unified images have a different signature. The moment you use the partition upgrader it will change the accepted signature and will no longer allow older images. If all is as I expected your running image is still the parition upgrader image and it contains the tools to perform the last step of the re-partitioning (e.g. calling the script and performing a recovery with format).
If you want to know what is going wrong with the zip install check the /cache/recovery direcotry. it will contain logs of the failing install.
As for a solutions I think you either need to run the script or flash your device using a 1.6 FUSE image.

I couldn't find any (log) files in /cache/recovery, but...
flashing the EBR1 from the FUSE binaries (FP1U) to my FP1 solved it! :victory:
thanks to _keesj, Rick (from Fairphone) and Christian (Fairphone forum)!
here is Rick's tutorial (with a few notes of my own):
You can only fix this by flashing your phone:
For GURU's only! (flashing with ADB). The alternative is to use the windows flasher tool.
1) Download the original image binaries from Fairphone's site (as a new user I, jjjanssen, can't post links yet).
(Download FP1U's zip: Fairphone_Cherry_1.6_FUSE_Image_2014-07-31.zip)
2) unzip the file
(I chose to unzip to location D:/FP1U.
after that i moved all content from the directory which contained EBR1, to D:/FP1U.)
3) enable usb debugging (on your phone: Settings, Developer options, turn USB debugging on)
4) push EBR1 on the phone: (Open (if you're using Windows) the Command Prompt)
adb push FP1U/EBR1 /mnt/sdcard/
(For instructions on how to use ADB search this site)
5) become root:
adb shell
(after that I also became super user (command su), but maybe that's not necessary; Rick didn't mention it. )
6) override the partition inforation:
dd if=/mnt/sdcard/EBR1 of=/dev/ebr1
7) reboot into recovery:
reboot recovery
8) choose to wipe data and cache
(after that, choose reboot)

[Q] Senior needs help rooted Nexus 7 and lollipop update

Please help and please be kind and patient with this senior citizen.
I have a rooted Nexus 7(2013). It is rooted at 4.4.4.
I saw the released Android updates to lollipop that I want to use and I need help with the procedures as I have to deroot my Nexus 7 first?
I also want to break it down to steps.
I assume that to update to lollipop, I would need to:
Backup using Nandroid
Deroot my Nexus.
Go to the Android site, then update to the latest version of lollipop.
When the upgrade if over, then re-root.
Even, though I was able to root my Nexus 7, I have forgotten many of the specifics.
Please help guide me as I think I need to:
Backup my Nexus 7 – I have both Titanium Backup Pro and Nanroid Backup Pro
Should I use Nandoid Online backup to ensure I can recover?
Nandroid Settings - Please help me with these Nanroid settings aftger selecting Custom Backup.
Backup Name – UTZ Timezone
Type – TWRP or Clockworkmod – I assume I select TWRP
Normal Backup Mode?
Do I select any of Yaffs2 as Tar or Exclude Dalvik Cache, Exclude Google Music Files.I have to admit, I have no idea what Dalvik and Yaffs2 are.
I will move to TWRP backup to my PC because it winds up being about 3gb and I haisve a 16gb Nexus 7.
This is where I get very confused. What exactly do I do and use start the derooting? Should I use the WugFresh(1.99) toolkit?
After derooting, I should NOT restore anything. I do an upgrade of Android to lollipop.
After my Nexus 7 is lollipop, I would need to do a recovery/restore of my Nandroid backup??
I have the following products that might help:
Titanium Backup Pro
Nandroid Backup Pro
BusyBox Pro
SuperSu
Root Checker Basic
NoBloat Free
Thank you for your time, expertise, kindness and patience in advance
Jon
Need a little more information. Understand you are rooted, but do you have custom recovery installed?
You actually don't need to remove the root before you update to lollipop if you use a factory image from Google.

This is where I get confused and think that I am overcomplicating things.
I don't know if I have a custom recovery installed? I assume that I would have had to have made one. :crying:
How can I check? In Nanroid?
Can I make a new one?
It is great if I don't have to remove the root to upgrade to lollipop. When I was promoted by Google to update to lollipop, it failed, because I was rooted.
The bottom line is that I want to upgrade to 5.x and want my Nexus 7 rooted. :good:
Please tell me what information you need.
Thank you,
Jon

Alright, so the fact that your Nexus received the prompt to update tells me that you do not have custom recovery installed.
What you are going to want to do (easiest way to update as far as I am concerned) is just flash a factory image from Google. In order to do this, you will need to get your hands on a few things first:
1.) Windows PC/Laptop
2.) Micro USB cable
3.) ADB and Fastboot files (http://forum.xda-developers.com/showthread.php?t=2588979)
4.) Factory Image from Google for Lollipop for the N7 (https://developers.google.com/android/nexus/images - If you have the 2013 N7, get the one that says 5.0.1 (LRX22C) under the heading "Factory Images "razor" for Nexus 7 [2013] (Wi-Fi)")
5.) ADB/Fastboot USB drivers (your Nexus should install them when plugged in while booted to the Bootloader)
Now, download the ADB and fastboot files. Go to that thread, and follow the instructions to install ADB and Fastboot SYSTEM WIDE so that ADB and Fastboot will work from any directory (makes the rest of this process VERY easy). Once you run through that installer, and everything is good, download the system image listed above. Once it is downloaded, go to the directory it was downloaded to, and UNZIP it (right click it and select Extract here, or open the file and select Extract All).
Now, power off your N7, and then power it on, holding VOLUME DOWN. You will be booted into the BOOTLOADER, this is known as FASTBOOT MODE. Now, connect USB cable to the Nexus 7. The computer will probably say "Installing Device Driver Software". Let it finish. Now, press the START button, and in the search box, type CMD. A command window will open up. Type in the following without the quotes: "fastboot devices".
Now it should show something like this:
Code:
List of attached devices
HJFK54HSWE fastboot
If it says nothing, then the drivers are not working. Reply back to this thread, and I will explain how to update the drivers (don't want to confuse you now). Now assuming that everything is working correctly, all you still have to do is flash the 5.0.1 factory image. Close the command window that is open, and go to the directory where you downloaded the factory image. There is a file inside that folder called "flash-all.bat". With the tablet connected and in fastboot mode, double click the flash-all file. That will do EVERYTHING necessary to flash the factory image, and your tablet will reboot in lollipop.
Now, I don't think this will overwrite the root. If it does, and when you reboot, SuperSU or Superuser (whichever you were using before) isn't in your app draw, then reply here, and we will root you up.
"Factory Images "razor" for Nexus 7 [2013]
Why the hell is it named 'razor' in DL area?? This machine is 'FLO', right???
Razor is the name for all 2013 Nexus 7s. From there, you have deb and flo to differentiate between the LTE and Wi-Fi models.

Actually, Razor is Google's code name for the Flo, and the Deb is the RazorG. Just like the Nexus 9 is the Flounder on XDA and Volantis on the Google image site. There are almost always two code names for Nexus devices (the community code name, and then Google's, just to keep everything as confusing as humanly possible..)
^^ LOL, but how totally stupid. In their own factory images download area, there are SEPARATE download areas for WIFI/LTE... why in God's name don't they use DEB/FLO? -______-
