I do not know how to restore my android mobile operating system.
At a few months ago, I had made a post for help on my android phone on this forum, but until now I have not been able to fix my android system.
Problem:
At that time, I'm interested in from the android system update and then I download GSmart_G1315_V0.50.2_PL_CZ.zip which, according to a tutorial that I could read in spend on upgrading the android phone Nexian nx-a892.
I then tried to follow the tutorial,
Starting from sw_ver.txt edit the file in /system/etc/sw_ver.txt (Using Root Explorer) says "BUILD_SW_PROJ = Nexian", I replace the "Nexian" with "pl_cz" according to the tutorial.
Then edit the file build.prop in /system/build.prop and replace all the "Nexian" with "GSmart" and "A892" with "G1315".
Then do the update from sdcard to file Update.zip
At this moment I am having a problem, because there is a warning error, but the operating system can still get into the android desktop.
I then opened explorer and re-edit root /system/build.prop in this section:
"Ro.product.model = Nexian A892", delete "Nexian" then save it.
then I go to /system/app/ .. and remove all the applications in it,,, I like hypnotized make the same mistake.
**** Error occurs when phone restart... *****
Expect the solution:
Among my friends, who can help me solve this problem?
I can only get fastboot mode but can not perform the update from here.
I can not do the update from sdcard, warning always appears E: Error in line7.
I want to activate adbmode, does not work at all.
Help from friends so I would expect. Previously I thank you.
No body can help me in this forum. Ba*

Once you have unlocked the bootloader, you need to root the phone. Once rooted, download titanium backup. That will allow you to uninstall all the bloatware apps

Hi, I have a Lenovo A690 phone. I need to root it. A friend found me a A690_Rootkit. How do I use it ?
It consists of
SP_Flash_Tool_exe_v3.1224.01 folder
recover folder
driver(A690)
A690-rootBy9Sky.zip
Any help would be appreciated if anyone knows any instructions. Thanks
Good Luck for your A690
Hello Marculos,
I too bought this phone 1 month ago. The advantage is that it is quite cheap on chinese websites, and quite powerful (good rapid chipset, nice screen), , but the main drawback is that is isn't rooted, and only in chinese/english (US), and that it is full of chinese bloatware ... and misses Goggle PlayStore
However I managed to root it, install a nice CUSTOM ROM with root, install Goggle Play Store, move apps to an EXT2 partition on my SDCARD to save memory, remove bloatware (the most difficult was to know which program to remove, as most of them were written in chinese).
To root your phone (if you trust your friend that provided the zip to you), you will have to proceed carefully, as usual.
There are many forums that explain how to do it ; it is always the same operations, so I don't understand why you did not find one.
1 - follow the tutos to install the drivers (allowing your phone to connect to flashtool in the right protocole for flashing)
2 - follow the tutos on flashtool to install the CWM that should be in your 'revover' folder (follow tutos on CWM ; yours should be a 5.0.2.7 based one)
3 - follow the tutos to install your A690-rootBy9Sky.zip Custom Rom
4 - Enjoy
take care that your custom rom might be in chinese when you reboot ; you will have to select english language using the menus written in chinese letters !
Don"t forget that these operations might brick your phone if you perform a bad operation or forget something (even if the phone is a cheap one, that's always ennoying).
I can't help anymore.
Good Luck
I have also got the Lenovo A690 and have been searching the net for a way to route it, I think I need that zip and maybe a link to a how to.
would be great help as its driving me crazy over christmas weekend and its the only phone I have.
It's crazy the phone is like unusable as it has hundreds of apps preinstalled in chinese which I cant remove and there is not enough room to put any more on the phone even with an empty 8gb sd card in it aaaaahhhh
A690 CWM and Custom Rom
Hello dominiclodon,
You can easily find a custom ROM for the A690 by seaching 'needrom a690' on internet. You will have to register to the needrom website, which is currently the only one providing a custom ROM for this phone; and then download all the given files (the drivers, the flashtool, the revcovery (including the CWM-based 5.0.2.7) and the ROM (version 1.4a looks aliek android 2.3.6 and version 1.5a looks like andoid ICS).
Take care that the CWM-based is in chinese (menus are sorted in quite the same order as for an english version). Custom rom is also in chinese when flashed, but after that, you can change the "language" to English US.
The ROM includes root privileges (you will see the Superuser icon), and a RE (in chinese).
I personally removed all bloatware after having installed a browser like Root Browser, and moved most of the user apps on the EXT2 partition of my SD card thanks to Link2DS app. Then installed all useful stuff (AVG antivirus, LBE privacy firewall, a french language package, a Go keyboard (the olnly one installed in the ^hone was the chinese "Sogou" keyboard !).
Everything can be found on the numerous tutos in XDA or in the web.
Good luck

Thanks for the help. I have to say I find the instructions I have found as clear as mud ! I can see how to install the USB VCOM and MTK USB drivers. The PDF states that the firmware should have 3 folders apdb, modemdb and target_bin. I can't find these.
When you load the scatter loading file theer are a bunch of files that are needed in the target_bin folder which I can't find. Any ideas ?
rooting help
I have found a guide here too
http://test.zhaoxinpeng.com/viewjy.php?id=77b8dc7f27ec456174eab6b5
from what I can see you need to roughly:
Turn off phone
Connect to usb
Install downloaded USB drivers
Load the flash tool
Open MT675_Android_Scatter from recover folder
Untick or tick ? Preloader
Click download
Then boot the phone into recovery mode (power and volume +)
Then unsure !!
rooting
ok .. so I think I sort of understand now. I need to replace the recovery image using the flash tool. Then boot the phone using teh new recovery image and install the required zipped firmware and job done..I think.
I am having issues trying to replace the recovery image. The phone gets detected by the flash tool but depending on the recovery.img used I get errors.
1/ BROM ERROR : S_FT_NEED_DOWNLOAD_ALL_FAIL (4050) .. or
2/ BROM ERROR : S_FT_DOWNLOAD_FAIL (4008)
I am using Win 7 x64. Any ideas anyone ?
driver issue

Ya i agree with you..if you are sure that the rooting procedure is meant for your device then go ahead
how to root
Here is how I rooted my Lenovo A690. THIS WILL WIPE EVERYTHING INCLUDING IN MY CASE THE IMEI. WARNING !!!
What you need:
MTKdroidTools_v229.exe - only needed if you wipe your IMEI
Full A690 Firmware - got mine off Pandawill forum.
Try this :
http://74.86.85.61/showthread.php?15487-ROM-Lenovo-A690_S012_121018-for-sku35508
or google below - this is the one I used
A690_SO13_12105.
Below all available from needrom. You will need to register
http://www.needrom.com/phone-roms/lenovo/a690/
USBVCom driver
SP Flash Tool - I used v3.1220.01
Recovery.img (in recovery zip)
A690 ROM in zip file. I used a690_s013_121207_v2.0_9sky
On a x86 Win 7 pc .. extract all downloaded stuff
1/ Connect phone to pc with usb cable. Do not switch on. When prompted for a driver install the USB V Com driver. Should show up in Ports.
(usb2ser_Win7.inf)
2/ You need to maybe change the checksum.ini in the folder with the full ROM in. Change CHECKSUM_SWITCH=1 to 0.
3/ Open SP Flash Tool.
4/ Open MT675_Android_scatter.txt from the full ROM folder, NOT the recover image.
PRELOADER
DSP_BL
UBOOT
BOOTIMG
RECOVERY
SEC_RO
LOGO
ANDROID
USRDATA
5/ This should load a bunch of files as above needed to flash the phone to the stock ROM.
6/ You will need to change the recovery.img to the one downloaded from needrom website. This will load the modified CWM recovery image needed to load the custom firmware. You may need to change the checksum value as above...
7/ Click "Download"
8/ Connect your phone. (Take out battery then reconnect)
9/ If all good you should see a nice green circle and the CWM recovery image should have been loaded together with stock ROM.
10/ Next, copy the custom rom you want to use to the root of the SD card on the phone and rename to update.zip
11/ Reboot the phone, press vol + plus power. You should now see CWM-based recovery
12/ Choose the second option ??/sdcard/update.zip.
13/ Press the bottom left button and the ROM should update.
14/ That should be it ! Mine booted in chinese only and took me a while to find the option to change to english.
15/ If you get invalid IMEI error then you need to recreate the IMEI values. I used the MTKdroidTools_v229.exe tool to reenter both IMEI (same for both). The IMEI is printed on the back of the phone. You can also set the IMEI from a terminal app on the phone.
I've go this error when rooting

I'm not sure if the stock rom can be rooted. I tried with all the tools out there superoneclick etc and couldnt get it to root with these tools.
I had no success just trying to replace the recovery.img so I replaced the entire rom (if rom is right terminoogy)
Did you use the rom downloaded from Pandawill link ? These files below are needed for full flash (replacing the standard recovery.img with the CWM recovery.img).
PRELOADER
DSP_BL
UBOOT
BOOTIMG
RECOVERY
SEC_RO

Now its rooted Ive added a 16gb sd card and used link2sd with a 2nd partition for apps and I can install a ton more apps than before. I can't get a google account natively working either but doesnt bother me that much as just use 1Mobile Market for apps, and 3rd party email app.

I had no joy just replacing the stock recovery.img. You need to replace the entire ROM from pandawill link (with new CWM recovery.img).
I replaced the entire ROM together with a new CWM recovery.img then loaded a custom ROM as an update.zip. This was the only way I could root the device. I'm not sure if its possible to root the stock ROM.
Hi Guys
I am running stock Android 5.0.1 LRX22C on my Nexus 2013 which is rooted and has TWRP installed.
I just got a notification that an update (9.8Mb) to 5.0.2 was available - however when I accept the update & the device reboots - it boots to TWRP?
Do I have to unroot / uninstall TWRP (go back to stock recovery) to be able to update to 5.0.2 or is there an easier way?
Thanks in advance for any help
You don't have to uninstall twrp.. You do have to unroot though.. If you use wugfresh's nexus root toolkit, it's pretty easy.. You just need to backup your important apps /data, and click the unroot /back to stock button. Select which version of Android you are currently running, and it will unroot your tablet. Then go back in and become a developer (settings, about, and tap on the build number 8 times) .. Then go into developer options, and re enable usb debugging.. After that, install the update.. Finally go back into nexus root toolkit, and re root the device... Fairly easy

Nice one - thanks very much. Not tried the WUGFRESH toolkit as I have always used the MJSkip version - so will give it a whirl
I unrooted (manally.. toolkits.. meh) and did the OTA last night, but just got bloops...
I downloaded the full package and flashed system.img, back up and running.

What did you use to flash the system.img? Will Flashify or Odin do it or do you have to hook up to a Windows PC and do it that way?

Cheers - am in business - now running 5.0.2 & TWRP 2.7.1.1
Have a weird issue - I have made a TWRP backup which I can see in the TWRP folder on my SD card when I use the built in file manager in TWRP.
However - when I boot Android 5.0.2 & use ES File Explorer the TWRP directory on the SD card of the Nexus 7 is not visible.
I have an iMac & when I connect the Nexus 7 to the Mac (using Android File Transfer (special app for Mac) I still cannot see the TWRP directory
How do I make this visible to Android? I need to copy over the TWRP backup to the PC for safe keeping & the free up some space on the Nexus 7.
Thanks

Any reason you went with a version of TWRP from six months ago instead of the latest version? http://techerrata.com/browse/twrp2/flo
As for pulling stuff from SD, I have no idea, maybe try the thing someone suggested with selinux (restorecon). I don't use MTP to do any transfers, all of my sd card backup stuff is done using rsync and automated by Tasker.

@kilroystyx lrx22g puts me in a boot animation loop and all above versions on my nexus 7 2013. Only 4.4.4 factory image works for me but google play services and store crash. How can I upgrade without being stuck on the boot animation? This is driving me nuts. Tried cleaning cache, factory resets, formatting, etc. Please help! Thanks, Cindy
