You have to debrand your phone...
That means: unlock bootloader + twrp + root + flash oeminfo dual sim C432 + repair corrupt firmware

After last step (repair corrupted firmware) you lose everything (unlock bootloader, twrp, root)...
Repair corrupted firmware is doing with emui and stock firmware in dload folder and the phone is stock again...

If you flash oeminfo, phone firmware become corupted and is need to be repaired.
For that you have to have in dload folder a stock firmware (B130/131, B160/161) and power up phone with 3 key combination.

EMUI 5.0 to LineageOS 14.1 ?

Hello !
First, sorry for my bad english, i'm french
I would like to know if there is a simple way to switch from EMUI 5.0 to Lineage OS 14.1 ? And if yes, how (with the fingerprint sensor working) ?
And if there is no way to do that, how to go from EMUI 5.0 to EMUI 4.1 without brick the phone ?
I have a VNS L31
Thanks for your answers

Hey, i know how to rollback from N to MM (VNS-L31) (NO FROM CUSTOM ROMS, IT WORKS ONLY ON STOCK ROM!!!!!)
0) Backup all things in huawei Backup (backup from N is compatible with MM also.)
1) Download this file http://download-c1.huawei.com/download/downloadCenter?downloadId=93787&siteCode=de
2) put the update.app to sdcard and with 3 buttons method update- in settings you will see build number B300 (universal firmware patch)
3) Take B160 Firmware update.app and repeat like in 2)
Bootloader will be locked. This is the save and official method how to roll back.

For rolling your phone back to EMUI 4.1 follow these instructions here: https://forum.xda-developers.com/hu...torial-rollback-n-to-mm-c432-devices-t3563955
And if you are on c432 localization just download the correct files for your phone. If you are on other localization download the files for your localization and do the steps correctly and you will never end up with a bricked phone.
This worked for me tho. Twice. I still have alive non-bricked phone. :laugh:

Cannot upgrade from VNS-L31C900B160 to Nougat

Hi all,
I have a problem with a single-SIM P9 lite (VNS-L31), which is currently on C900B160 (manually updated following the "standard" manual procedure via dload directory on SDcard): I cannot upgrade it to a C109B350 (that's the one my wife has now; we both were on C109B163).
Is there any way I can move on to have Nougat on my phone?
Thanks in advance

Firmware finder proxy install . Download app ( firmware finder ) from Google play . Open it , go to settings and download proxy install . Find ROM to ur phone and click " proxy install" . Then proxy installer will tell u what to do . Download 1 % of ROM . Pause it. . Set ur wi-fi settings like it was before . Resume it and it will upgrade ur phone to nugat . What rom should u download ? Find ROM to ur phone with ".PV" . if u will try upgrade another version like full ota or something it will damage it ROM and it will work but u wont have half of apps . When u upgrade to vns-l31c109b3xx.PV then u can upgrade any other version . But like I said . When u are on mm upgrade only using .PV
If I help u click thx

IF firmware finder don't have rom to ur phone u can try fastboot

not working...
After getting the update file, there must be some problem with my customization level (I'm trying to move from C900 to C109 - there's no mm for C900 available), because I get an error when trying to update to C109B350.
Any ideas?
BTW, in the latest version of firmware finder, there are no .pv versions... :-/
Thanks everyone!

Btw . I never change region settings . I was always on c433 so don't ask me how to change it . I can help u with ROMs/bricks/etc
But in my opinion flash via fastboot should force c109 update ?
