Hey guys!
I've installed the Nougat beta for my P9 Lite VNS-L21 Dual Sim, but now I want to downgrade to MM. This is what I did:
0. Installed Nougat via Melticulus TWRP
1. Installed Revolution Recovery (because Melticulus TWRP had stopped working, idk why)
2. Flashed OEMInfo
3. Copied Version B150/B151 (I've tried both) to the SDCard
4. Started the P9 Lite with Power + Volume UP + Volume DOWN and tried to flash one of the versions.
I'm stuck here, the Huawei Recovery says the following: "Software install failed! Incompatibility with current version. Please download the correct update package!"
I've used HTC Mania, Thread NR 1200630 to download the stock rom for my P9 Lite, I've tried both the VNS-L21C432B151 Android 6.0 EMUI 4.1.1 Europa and the VNS-L21C432B150 Android 6.0 EMUI 4.1.1 Europa

You have to debrand your phone...
That presume: unlock bootloader + twrp + root + (prepare in dload folder a C432 - B160/B161 firmware) + flash oeminfo C432 + repair firmware with dload folder.
It is a lot to do and somethings may goes wrong resultin in bricking your phone...
If you assume the risks, after that you have a C432 - B160/B161 phone which can be updated to B370/B371 via Firmware Finder.

Since you are here and obviously know a lot more about p9 lite than me, can you please find me a guide to do stuff that you told me to do. I know it's a lot to ask for, but I've been grinding all week trying to find guides etc and couldn't. Thanks in advance!

What you have to do i already said but you have to read arround here to do followings...
1. From anywhere you are (B336, B329, B170-160-130) you have to prepared in dload folder a B160/B161 stock firmware (B160 for Dual Sim, B161 for Single Sim).
2. Flash oeminfo/custom.bin (for SS phone or DS phone ) for your phone localisation: C150, C185, C432.
3. After that firmware become corrupted and need to be repaired from dload folder via 3 keys pressed / dialer code / emui error message.
4. Once you have a functional B160/B161 firmware install Firmware Finder (+proxy addon) and check <Use new firmware> and <Use system updater>.
5. Reconfigure WI-Fi connection from indications in Firmware Finder Proxy.
6. Search for B370/B371 firmware (B370 for DS, B371 for SS) of 1,94 Gb size for your phone localisation and send it to updater.
7. From there it is downloaded, verified and reboot to emui updater wich make his work and bring you B370/B371 firmware.
PS: - for flashing oeminfo/custom.bin i recomand this tool which make that work just fine.
https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
- if you have a flash-able zip of oeminfo/custom.bin i recommend flashing with twrp.

I have L31 and I want to debrand it from C440 to C432. I did some research, but still I have some questions.
1. Unlock bootloader + TWRP + root - I found this https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
It's ok right ?
2. Flash oeminfo of C432 and this should be done by SRKTool and oeminfo I found there https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
3. repair firmware via dload folder - Unfortunately I don't know how to do it. In the instructions for p9, it was done also in SRKTools using "Install Recovery 6.0", but there P9Lite is not mentioned, how should I do ?
4. Install new ROM - I should install new ROM for c432, right ? It's using 3 button method ?
And that's all ?

Regarding <3. repair firmware via dload folder>, you have to download stock firmware for C432 (B130/131 or B160/161 - depends what oeminfo you flash),
unzip update.app and copied on dload folder on microsdcard. Power off and power on with 3 key combination and repair start...
At the end you have a brand new C432B1XX phone...

Indeed, you lose bootloader unlock, twrp and root (if you have).
If now I have c440B160, and I place oeminfo for c432 do i have to install c432b160 or I can install c432b131, because I only found that version
I installed TWRP and Root, and now I don't know how to change oeminfo, because in srk is only p9,not p9 lite, and I downloaded package .zip and tried to install it by TWRP but it didn't work. How should i do this ?

I have to know your system version that you have cancelled and the recovery version, because Nougat is different from MM
What phone do you have? (Back of the phone it tells you what VNS is. Say what VNS is.)
Ask somebody to send you a backup of their rom.

p9 lite vns FUH7N17311000495 (backup folder) :S
where do i find the VNS number
You can try to recovery the stock ROM with dload method.
1. May sure that you've flashed the OEM info. It will lock your bootloader.
2. Put update.app in dload. The version can be b161.
3 update.
Reboot

Hi,
1) wipe Dalvik & cache, flash stock recovery of b370, and then do like you wanna update to b380 using firmware finder, (use the big file)
or
2) rollback to MM : flash oeminfo for your location (recommended) , flash Rollback Package via dload , and then flash stock B160 via dload.
or
3) remove root from SuperSu app, then use Rocatex uninstaller
