UPDATE TO THE MOST RECENT VERSIONS NUGAT AND OREO
FLASHING METHOD


HTML Code:
- An advert! The Flash phone can have bricks. I'm not responsible for that:p:p.
- If you are not sure, do not make any changes and you can leave this forum:confused::confused:.
  • - This method uses a modified stock recovery that does not verify the files.
  • - It serves to update firmware, as well as update to Oreo, but not to do Downgrade Nougat.
  • - also serves to perform rebrand changing cust.
  • - make copies of data and applications.
  • - I will not explain how to unlock the bootloader and install twrp, there are many tutorials.
  • - with this method the bootloader will be blocked again.


REQUIREMENTS:
  1. - activate OEM unlocking from developer options.
  2. - Unlock the bootloader.
  3. - install recovery twrp P8 lite nougat
  4. - download the firmware finder.exe to download the updates
  5. - download the firmware of your compilation and / or rebrand compilation
  6. - Download the HWOTA file and unzip.
  7. - minimum battery of 50%

PROCESS.

FLASH UPDATE
  1. - unzip the file HWOTA.zip
  2. - download the firmware of your compilation (settings / about the phone)
  3. - the firmware is three files in the update.zip, update_data_full_public.zip and update_full_XX-LXX_hw_xx
  4. - the latter "update_full_XX-LXX_hw_xx" there are usually several L21, L01, etc. just download one and it will depend on the cell model.
  5. - If there are not three, it does not work.
  6. - Rename the firmware as follows : update.zip, update_data_public.zip, update_all_hw.zip
  7. - copy and paste the renamed files into the "HWOTA" directory.
  8. - the HWOTA folder, copy and paste in the external memory.
  9. - turn off the cell phone and boot in recovery twrp.
  10. - change to external memory.
  11. - find the HWOTA folder and flash the OTA_catuva21.zip file
  12. - the cell phone will automatically restart
  13. - and start updating let it finish
  14. - if for some reason it remains on the black screen, or sticks to the huawei logo
  15. - perform hard reset (press the volume more and power, and perform both wipes)
  16. - CONGRATULATIONS UPDATE YOUR ANDROID.

REBRAND
  1. - unzip the file HWOTA.zip
  2. - download the "PRA-L...C...oeminfo.zip" (it's a flasheable file)
  3. - download the firmware, this depends on the brand you want to change "PRA-L... C...oeminfo.zip"
  4. - rename updates: follow steps 3 to 8 of FLASH UPDATE
  5. - Create a folder in the external memory and paste the "PRA-L ...C ..oeminfo.zip" of your selection.
  6. - turn off the cell phone and boot in recovery twrp.
  7. - change to external memory.
  8. - search the folder oeminfo and flash "PRA-L ... C ... oeminfo.zip"
  9. - DANGER DANGER
  10. - when finished flashing DO NOT REALIZE REBOOT SYSTEM
  11. - return to the main screen.
  12. - select reebot.
  13. - select bootloader and automatically restart in fastboot mode.
  14. - and as you will see the bootloader is blocked.
  15. - unlock the bootloader with your code (if it is in red, just unlock)
  16. - once unlocked it will boot in recovery twrp.
  17. - search the HWOTA folder
  18. - find the HWOTA folder and flash the OTA_catuva21.zip file

You really gonna laugh at me. I was rebranding my huawei PRA-LX1 and I already unlocked the bootloader. Successfully done all firsts 9th steps but when I had to unlock bootloader I figured out that I didn't keep the bootloader code from the last time... Then as the website is under maintenance I had to call huawei support, not open during the week-end in my country... During these days stucked in bootloader mode, it runned out of battery and powered off. I finally get the bootloader code from huawei but when trying to unlock I get "Wrong password" from fastboot. I tried to update via dload method but it didn't work I have no idea what I can do to fix it. Are there any chances to unbrick my device?

Thanks,
Nathoufresh
Sorry for my bad english
