C10 is the region here it's Russia (check the list of country and region code). Now, B141 is incremental no of update (and it keeps incrementing.....wow). Here is some build code:

CAM-L21C223B131 -

Quote:

Q1. I can't take TWRP Backup. /data mount error. Invalid Argument.

>> In TWRP>WIPE>Advance Wipe>Data>Change File Format> choose fat/f2fs etc.>Swipe to confirm
Then Again TWRP>WIPE>Advance Wipe>Data>Change File Format> choose ext4>Swipe to confirm.

Q2. How Do I know if Bootloader is locked or unlocked? I forgot.......

>> Boot phone into Fastboot mode and give this command: fastboot.exe oem get-bootinfo

Q3. Hey! I Flashed the wrong recovery image. I did not took backup of stock recovery. Now NO TWRP, NO EMUI Recovery. WHat to do??

>> It's nothing Relax! Take your Firmware (Only your Model, be careful) extract recovery.img using Huawei Update Extractor Tool. Then Flash it using Fastboot command. See above instruction for that. If you don't have exactly same firmware build version then take one or two increment updated firmware version. For example, When you flashed wrong recovery your phone firmware build was CAM-L21CXXXB140 then download exactly this file, for any reason if you don't find this then download CAM-L21CXXXB141/CAM-L21CXXXB150 etc. Extract recovery.img and flash it.

Custom Roms
Thank you very much for all these informations.

But in the stock Rom (Emui 4) there are a big issue. That it closes the application on screen closure even if these applications are protected.

So I am looking for any athor rom that works in this model. Or an update to emui 5 because it seems that they have solved this issue in this update.

Thanks in advance
