[Huawei P9 Lite Guides, News, & Discussion] CATUVA21:
UPDATE TO THE MOST RECENT VERSIONS NUGAT

FLASHING METHOD​

- 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, but not to do Downgrade MM.

- 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.

EXPERIENCE

- my compilation was VNS-L23C605B342 and update to VNS-L23C605B385 (demo video)

- being in VNS-L23C25B I changed from cust REBRAND, to compilation VNS-L23C605B385 (demo video)

REQUIREMENTS:

- activate OEM unlocking from developer options.

- Unlock the bootloader.

- install recovery twrp P9 lite nougat

- download the firmware finder.exe to download the updates

- download the firmware of your compilation and / or rebrand compilation

- Download the HWOTA file and unzip.

- minimum battery of 50%

PROCESS.​

FLASH UPDATE

- unzip the file HWOTA.zip

- download the firmware of your compilation (settings / about the phone)

- the firmware is three files in the update.zip, update_data_full_public.zip and update_full_XX-LXX_hw_xx

- 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.

- If there are not three, it does not work.

- Rename the firmware as follows : update.zip, update_data_public.zip, update_all_hw.zip

- copy and paste the renamed files into the "HWOTA" directory.

- the HWOTA folder, copy and paste in the external memory.

- turn off the cell phone and boot in recovery twrp.

- change to external memory.

- find the HWOTA folder and flash the OTA_catuva21.zip file

- the cell phone will automatically restart

- and start updating let it finish

- if for some reason it remains on the black screen, or sticks to the huawei logo

- perform hard reset (press the volume more and power, and perform both wipes)

- CONGRATULATIONS UPDATE YOUR ANDROID:cool::cool:.

REBRAND

- unzip the file HWOTA.zip

- download the "VNS-L...C...oeminfo.zip" (it's a flasheable file)

- download the firmware, this depends on the brand you want to change "VNS-L...C...oeminfo.zip"

- rename updates: follow steps 3 to 8 of FLASH UPDATE

- Create a folder in the external memory and paste the "VNS-L...C...oeminfo.zip" of your selection.
