Guys , some people are reporting that they are unable to revert to stock rom after flashing custom rom.
If you want to save your phone , then i highly recommend you to make a complete backup before flshing stock rom
go to cwm recovery and select backup/restore then backup (it will make your stock rom backup)
whenever you want to revert , go again to clockworkmod recovery and select restore under, backup/restore option
now last and most important thing to run stock rom ---> flash stock kernel using fastboot method
first grab stock kernel to do that , download your phones stock firmware from here = http://forum.xda-developers.com/showthread.php?p=10885406#post10885406
using 7zip extract kernel.sin file from .ftf firmware file
connect your phone in fastboot mode and run this command
fastboot flash boot kernel.sin
I'm doing it again and again without any problem.. just be sure to flash stock kernel before flashing stock rom.
thanks, i will try this method too
first flash stock kernel , then using flashtool flash firmware , am i right ?
Stock kernel (kernel.sin) is included in the package (of official stock firmware). So everytime you flash an official stock firmware, kernel.sin is also flashed. No need to flash kernel.sin before flashing stock firmware. Correct me if im wrong.
I also think same , i tried that method by noooooob and it worked too

yes you have to unlock boot-loaders first
i recommend to unlock by this method = http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
if you want to install clockwork mod recovery then follow this = http://forum.xda-developers.com/showthread.php?t=1384200

This is how I did it on my Ray
I always considered flashing with Wotanserver to be the best way to go back to stock. It basically takes care of everything. Sure, you'll have to root again afterwards, but that's not exactly very hard.
wotan server is also a good choice

download firmware which you have before installing custom rom, then flash it using flashtool.
So, today i bought my P780, there is preinstalled heweikeji CWM recovery v6.0.4.4, it's also prerooted, but i want to install TWRP recovery and every time when i try it via flash tool it say "pmt changed for the rom; it must be downloaded". I tried also instal twrp via mobile uncle tool, but there is still cwm recovery after reboot. Also it can't make backup, problem: "backing up boot image" and nothing happens long time after that, 10 minutes or more.
How to install custom recovery and how to find out version of firmware? I am not sure it's chinese or ROW? Which ROMs to flash?
Build number: VIBEUI_V2.0_1437_7.14.1_ST_P780
Baseband version: P780.V101, 2014/03/12 15:06
Thanks in advance!
I did it!
HowTo: Full backup with MTK Droid Tools, then in mtkdroidtool make scatter file and use them together with recovery.img (i downloaded ) with sp flash tool (SP_Flash_Tool_v5.1352.01), tried to flash with flash tools 3, but there was error on boot screen (tool DL image fail).
Now TWRP work flawlessy...
Hi i have a GR5 KII-L33 model (single sim), can i use any rom for kiw-l21, l22, etc. (CM13 and others)?
do i need to do extra steps? i dont want to brick my phone :silly:
Hey
make sure that you take full stock backup before flashing the ROM
use fastboot boot twrp.img to run twrp without replacing stock recovery then backup everything
after that you can flash twrp with normal command then flash cm
after flashing the ROM, you need to follow these steps here, to get your single sim working
I answered you in cm thread and here to talk more [emoji14]
And yes you can use any CM/AOSP Roms, don't mess around with stock roms

hi, just curious about the backup everything.
does TWRP backup our stock recovery partition? because you said that we have to boot twrp then backup everything. i wonder if we restore using twrp, will our old/original recovery return? i know that we can use update.app to restore stock recovery and rom.
i am new to this huawei device since i've been using htc one x and did flash custom rom also twrp. but my device is KII-L22 and keen to flash crpalmer's CM.
thanks.
I am looking for a working ROM for this device. I can't use recovery because my phone is stuck at formatting /data. I did a google search and I found that there are ROMs for the original viper (without I) but I couldn't find any for mine except the zips. But those has to be flashed in recovery which I can't access therefore I need to use SP Flash Tool.
I have only ever flashed the following after rooting..
1)twrp
2)super su (later unSU.zip-ed)
3)cm-13.0-20170116-SNAPSHOT-ZNH5YAO3Y9-condor.zip
4)lineage-13.0-20170621-STABLE-condor.zip
5)magisk
so..
do i need to flash stock firmware or stock rom using Retail Dual-SIM (Asia | World) 5.1 ROM (Untouched) (459mb)
if i use stock firmware.. ( referring to guide )
1) as i have never made modifications to radio/modem do i need to "flash modem NON-HLOS.bin"
2)as mentioned here
"WARNING: Flashing a Firmware Image is not a safe way to downgrade. Avoid flashing 'motoboot.img."
do i need to flash motoboot.img
3) i have twrp as recovery i would want it to remain so if possible in stock rom ... do i need to flash "flash recovery recovery.img"
THANKS.. any help is really appreciated.:angel:

1. See you can surely flash stock firmware there is no Risk unless and until you flash 4.4.2 and update it to 4.4.4 if you do it you'll most probably HardBrick your phone so my recommendation is to flash 4.4.4 or 5.1 and never update your phone via updater...
2. And yes you'll have to flash Twrp.img after flashing stock firmware as flashing firmware change your recovery to stock.
3. Yup motoboot.img is needed to flash.
4. Refer to the batch file I've attached.
