I was installing Custom Rom to Stocked LT15i with (Bootloader Status Allowed = YES) phone And i faced a strange problem that I never faced before. Below is detail of my problem
1. I Installed Stock 4.0.4 Stock ICS Firmware Via Flashtool before it was on same 4.0.4 but its was updated via PCC.
2. I Try to unlock its bootloader from official site i got the key and try to unlock but Fastboot command said its already unlocked bootloader. So I head to next step.
3. I rooted it with Prerooted kernel image. name ARC Autoroot v1 its worked fine.
4. I installed ClockWorkMod Recovery 5.0.2.7-nAa-r2 via batch command provided but a user in this section. worked fine.
5. Now Problem is Any Custom rom i want to install from CWM its give me (satus 7) eroor. I preceded steps 1 to 5 again n again but same error.
6. I tried all the solution for Error status 7 provided by user but no luck. like build.prop and removing some script.
one thing i noticed its IMEI start with 01 m not sure it is the cause. Let me know what is the easiest way to install custom rom to it. Its belong to my friend.
(I am able to flash any kernel )
I search all the night but didn't find solution so i ask.

Not sure what you've been searching for - status 7 error xperia arc

You need to flash compatible kernel for the custom ROM you are trying to flash.For example, when you download CM10 ROM, kernel boot.img is included in that rom zip. First we install compatilbe kernel(boot.img in case of CM10) and install rom zip from CWM.
Download and install CM 10 just to make sure you are doing it right.But first flash kernel first.

This is the first time I m facing such problem I have tried many phone and succeeded but don't know what is problem i have changed SD Card thought its make problem but no. Tried LT18i Rom same issue, MIUI+ Kernel, Cynogen + Kernel, Pac + recommend Kernel, Other + Kernel. I can't say its Internal Memory Problem coz i can flash stock smoothly.
And when i flash Cynogenmod Kernel its CWM not let me use SD Card say can't found SD card.

Sounds like you're using the wrong command then. The right one is fastboot flash boot nameofkernel.img

[Q] How does one revert one's Xperia S back to stock ICS from Cyanogenmod 10?

I'm asking because I specifically flashed another boot.img for Cyanogenmod 10.
Now, what are the exact steps I need to take to go back to stock ICS?
Do I need to flash a stock boot.img first, with fastboot or something, and then flash a stock ICS zip from ClockWorkMod?
I'm not really experienced with any of this, I've flashed only about 3 times but none of which required me to install a different boot.img (isn't that the kernel file?).
Any help would be amazing!

2.Flash stock zip Rom.

Can this advanced stock kernel be flashed from within CWM as well as the ROM? I used something I believe was called fastboot for it.
And the kernel is indeed the boot.img then?

If you want to go back to stock, dont flash anything..
Now reverting back to stock is much easier as sony has released an official flashtool, just download the tool and latest firmware and flash it using the tool..
Once again dont flash any kernel or any rom if you want to completely go back to
stock.

Yep sure There are 2 versions of advanced stock kernel. One is flashed via fastboot and another one is flashed via CWM.
Then, on CM, Pac, Para which Rom are not based on stock one, boot.img is exactly the kernel

I tried this, but I couldn't get the official flash tool from Sony to work.
I apparently had to have a company when making an account to log in. Very odd.
I assumed this other flashtool made by probably xda developers did the same thing, but that one always gives me an error that I need to install the drivers first. Yet I've used this program before and back then I already went through all the hassle to install the correct drivers.
And now I don't know which drivers to install anymore.

You need to follow the instructions in sony's developer website for installing the flash tool..
Did you install the drivers using the drivers folder in flashtool??
And does your phone get recognized by the flashtool, I mean does it show your android version etc etc..??

Thanks A LOT!
Sony's beta flashtool, Emma, works like a CHARM!
I initially forgot to copy the customisation file from the zip to the installation folder. Thanks for reminding me to check the instructions
The unofficial flashtool couldn't recognise my phone, but Sony's one could.

[Q] Need help installing Jellybean on my Arc S

Dear all,
Firstly, I'm new to this forum - hi. I have done an extensive search and found some guides but even those confuse me so I'd appreciated some constructive comments without any links to guides I may also find difficult.
I'm trying to install Jellybean to my device using a guide (that I currently can't link to because I haven't had 10 posts).
I have downloaded the two zip files it says I need (ROM and Google Apps) and have copied them to my SD card. However I don't know how to get into recovery mode to then load these. I downloaded RecoverX and tried to install it but it says my phone is either not connecting or is missing some drivers. I have busybox installed and my phone is connected with USB debugging enabled.
Can anyone advise me further?
Thank you.
What have you got?? Unlocked or Locked Bootloader ???
You forgot the first step.
Unlocking your bootloader
You have to unlock bootloader to flash custom jelly bean kernel. Then you can load cwm

Download the official cyanogenmod 10 and the gapps,flash the incluedid kernel.When the phone start press lot of time the volume down button.After format /system /data /cache just flash the rom and the gapps.

I got into recovery mode using X fast app (I think that's what it was called). I then backed up and wipe everything as the guide said. I then installed the cmon and gapps zips and rebooted but it just stays on the 'Sony' screen and I can't boot into recovery mode either!!! Help!

Restore backup, its only thing u can do right now. If u want to flash custom JB rom, u must unlock bootloader as said before because different versions of Android cant run on the same kernel.
To install custom rom, do this steps:
1) unlock bootloader (if possible, otherwise, u r stuck with ICS roms.)
http://unlockbootloader.sonymobile.com/instructions
2) After that, its simple - flash selected kernel via flashtool and then flash desired ROM!
And piece of advice, u have search on this forum, its quite usefull

Of course you can still use flashtool
You should flash back to stock Rom again and root again
If you want to use jelly bean, you have to unlock your bootloaderfirst

For that you have to flash via CWM the Google Apps or the so-called Gapps. Link: http://goo.im/gapps/gapps-jb-20121011-signed.zip (If you flashed the 4.1.2 official SlimBean). I help you because that's the ROM I use (but the 4.1.2 version, not the 4.2.2 by besttt)

There seems to be a problem ATM. There are links to the mega site where the .zip is in the instructions, but I will try and reupload to the xda server again later tonight
You messed something mate.
You said - flash ROM via CWM but you provided ftf file so I guess there's no need for that step or?!
It would mean we should flash ROM two times, from CWM and from flashtool....?

Thanks for the replies and the interest.
1) There is a link to the download in the download section at the top of the project. See the screen shot. However the .zip file can also be found here
2) The instructions are correct. You have to flash the .zip in recovery and root it using the superSU .zip. Then before rebooting flash the 257 ftf to install the 257 kernel etc. You exclude system because you want to keep the rooted system you just flashed in recovery. The ftf has to be flashed in flashtool.
3) Anyone can flash the ftf from any region. If you want to keep your basedand etc, then just exclude system and baseband in flashtool. If you want to flash a FTF of your region though you can flash any FTF and just exclude system.
4) I am currently uploading a direct link to the rom in the download section.

Hi guys i have a problem when I instaling the eXistenZ v2 on LT26. I rooted my phone i have recovery and when i install a rom have error nr 7 in revovery, any ideas?
Flash the kernel file from the rom itself
Try flashing the kernel from the rom itself bro this works most of the time Extract it first from the zip file of the ROM you want to install then install the kernel usually it is the boot.img file Flash it via fastboot mode using flashtool then voila you have the kernel of the ROM you want to use and most of the time the recovery comes with it too :good:

Are You on stock firmware? Existenz requires You to be on stock 6.2.b.1.96 firmware. Also, You have to flash v1 and then flash v2, not the v2 directly.

Huh, weird. Just to verify, could You try downloading the v1 again? Or else, do You have a unlocked bootloader? If yes, then You can flash the DoomKernel.
Yes, i downloaded rom again, and i have lock bootloader witch no posibly to unlock 'allowed-no'' something like this, but this rom can be flash without unlocked bootloader.

Well, since You have a locked bootloader, You can't flash other kernels. Try this recovery, If even this one doesn't work, then try going back to full stock(no root, no recovery) and root using DoomLord's method and try above recovery again as it had worked for Me earlier.

This is waaaay late but, may help someone.
As I understand it, this is an issue with the kernel/recovery you have. You need to flash a boot.img with a combined kernel/recovery that is compatible with the rom you wish to flash. You use fastboot for that:
Code:
fastboot flash boot boot.img
fastboot reboot
So, for official CM11, grab boot.img from the rom zip file and you should get (a rather old but fine for CM11) CWM recovery.
For many other Acro S (hikari) roms you find - e.g. @deedwar's BeanStalk - you will get TWRP recovery if you flash the included boot.img file.
Once you've got the kernel/recovery flashed, then you flash the full rom after the reboot.

I am just writing these steps to help those who want to downgrade from KK to JB due to any reason. Please use these steps at your own risk.
Some Background:
Recently I updated my Razr M to KK, it was Locked and Unrooted, but with the help of Twelroot and Motopocalypse I rooted and unlocked the BL.
Now somehow I didn't like the KK and wanted to go back to JB 4.1.2 because I was now having unlocked BL and rooted phone so it was easy but need to follow some steps to successfully downgrade to JB. So an unlocked BL and rooted with KK is must.
Prerequisite:
USB drivers for Razr M must be installed before proceeding.
Steps:
1. download the firmware file [Android 4.1.2
Blur_Version.98.30.1.XT907.Verizon.en.US] from http://sbf.droid-developers.org/phone.php?device=8
2. extract the above archive and replace the XML file with the one in attachment.
3. put the phone into fastboot mode and flash the firmware with RSD Lite (attached)
4. reboot and now you have JB 4.1.2
If you want to install root application again and also want to flash custom recovery then please follow the Post#5 [ATTACK] (thanks ATTACK)
Note : for custom recovery you will need the fastboot.exe if you don't have it then install minimal_adb_fastboot_v1.1.3_setup.exe(attached).
Put the phone in fastboot mode, copy the recovery to c:\ and execute the below command :
fastboot flash recovery [Path to recovery image]
If it help you then don't forget to press Thanks button !
Forgive my ignorance but this won't downgrade the kernel will it? I'm hoping it's possible to go from the newest OTA to the stable CM11 but I'm guessing this is new kernel JB. Either way thanks if I can't go to stable CM11 I'll stick with rooted 4.1.2.
Once you have a unlocked bootloader, you do not need to use "root programs". All you need to do is flash a custom recovery via Mfastboot / fastboot then flash SuperSU / Superuser.
In dhacker29's folder there are 2 different recoveries.
"msm8960" is for 4.1.2
"KITKAT" is for 4.4.2

Could you go back to KK when you've downgraded to JB? Just asking this question early before the CM11 M8 release and the transition occurs.

So just by flashing the KK firmware in RSD without any changes to the xml? Sorry for the noob questions, I realize how easy this phone can be bricked and I want to avoid it.

I see don't why you would need to. It would be just like restoring stock firmware via RSD Lite.
When I try to flash this, I get Failure on 2/20, sbl1

Can you please post the error that is displayed in RSD Lite ?
The steps are tested by my 2 times, and there shouldn't be any problem. Make sure you have installed the correct drivers.
Please ensure that your bootloader is unlocked and shows BL unlocked status code 3 on BL screen.
I was also able to successfully flash back to JB with House of Moto via fast boot and full data wipe. It would not work with Universal or Keep Data, had to do full data wipe. Just another alternative :good:

Thanks You Its a Success Downgrade From 4.4 stock > CM11 > Stock rom 4.1 Thank you so much !!!
For those undergoing the downgrade process in RSD Lite and it takes forever for it to finish and the system ends up without data/signal, you need to RSD Lite flash again in order to regain signal. I believe the flashing was sluggish due to the jump from 4.4.2 to 4.1.2 and the many changes that were reflashed.

Thank you so much for the guide. After a lot of trial and error (mostly error), I thought that I had bricked my lovely XT907. I finally restored KitKat by flashing the 4.4.2 firmware with the edited XML file (deleting lines with "Getvar", "var" and "oem" in them), then followed your guide to the letter and found myself with a perfectly functional phone once again. No more sticky fastboot loops or audio-related crashes for me!
Lovely guide - thanks again! :laugh:

What functionality does Busybox add? The description on the Play page is woefully sparse.
Thanks!
