First of all...
Restore your TWRP backup to get your OS back to work.
To downgrade from Nougat, you really need the RIGHT files.
So start by telling us which phone you have (L31 or 21?).

if you haveb't a twrp backup you can go to fastboot and flash system.img boot.img cust.img and recovery.img

Yea, but before flash oeminfo via twrp

k i have huawei vns-l31 i don't have any backup so thats the problem i forgot to make it thats kinda dumb

i only have some .zip file no .img files

Flash OEMinfo, then install version B150 (for me, it ONLY worked with B150 no other version) with the three button method.
Copy the update.app into DLOAD of your SD card with mounting storage in TWRP.

Flashable zip file that can be flashed in TWRP.
Link can be found here in the OP https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932
Look at the rollback section.

Nope don't have it I am on Lineage OS now so deleted all my stock related stuff.
Look at the HTC mania thread, the Spanish one. It is linked several times in these Nougat threads. They have a link to a collection of firmwares where there is also B150 for download.
Use a translator to find the link for L31 firmwares.

First, put the update.app from B150 into your SD card in the DLOAD folder.
Then flash OEM, then turn off device and turn back on with all three buttons pressed.

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 ?

Ministry of solutions has a full tutorial, I used it and it worked flawlessly

Ok, thank. That worked. But now I try to update phone by using firmware finder. It finds me a lot of versions and I downloaded the newest b381 full ota, and it failed, because something was wrong in that package

What u debranded to?

Now i have c432b160, at least it sey so. I used the ministry of solutions oeminfo and rom.

Update from B161 to Nougat - Once again

Hi Guys.
Maybe somebody can help here:
I am on B161 and get the OTA Update for B371 - but only the 2.5GB version! And with this update, bluetooth and many more things don't work.
What can I do to Upgrade to nougat? Which Version should I use? How to upgrade correctly?
I don't get the full B371 Upgrade option in the system. And when i Install the B371 Image from Firmware Finder (VNS-L31C432B371 FullOTA-MF-PV) its not working either...
PLEASE help, Nougat has a much better Ram Usage und battery life then MM on my P9 Lite 2GB Variant.....
Thanks!

Better wait.
Nougat has battery drain.

If your phone is stock and update is available via System Updater, go for it!

I was on B371 before but had the issue with bluetooth not working etc. Then i did the rollback package and afterwards went back to B161 - so i suppose its not really stock?
I'm just thinking - now i am on B161 and B371 Update is visible for me - but only the 2.5GB variant - and i don't want to update and have the same issues and again do the rollback and loose all my data?
Also i don't really now what it means exactly to be on "Stock" rom - because i think B161 is the actual Stock rom for now?
EDIT: Also i See i have the Firmware VNS-L31 but my Model is actually VNS-L21 so thats weird too.

Stock phone means unaltered phone (firmware official, bootloader lock, stock recovery etc)
If you have VNS-L31 firmware on VNS-L21 phone is not ok... So your phone is altered...

First of all you have to bring your phone on stock condition (VNS-L21C432B131).
After that you have to apply a B161 official update.
And from there, with Firmware Finder you go to B371.

lol ok i did the rollback with the rollback package which obviously only changes the oeminfo to VNS-L31C900B300 (as mentioned in another post to rollback from Nougat to MM)
Now when I try to Install the B131 Package with dload method it says the firmware doesnt fit. The build is not correct for this device
EDIT: i try now to install it via Firmware Finder, lets see if theres better luck with that - Or should I ? The update has only 1,5GB - that confuses me Allthough i selected the FULL OTA

Man I tried Tried to do the upgrade via dload method - doesnt work. I tried to install B131 via Firmware Finder - didnt work he cant do it - while verifying the update package switches a few times from 0 to 1 % and after some times he says the package is corrupt.
Can I go just higher than B371 to get everything working again?
Or flash back to B131 with some TWRP or something like that?
Or maybe try to flash the B371 with firmware finder again? That version where it says FullOTA-MF-PV (whatever PV means)

If i was you, i do following:
- first, i make sure if my phone is VNS-L21 (very important!)
- put in dload folder on microsdcard, update.app from B161 firmware: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66051/f1/full/update.zip
- flash via twrp oeminfo from this link: https://mega.nz/#!Egl01ZpJ!g1K9xV2yZ4oyoBKxFMOWgghTTUzqLUBoBeXkUboCi-A
- start phone with 3 keys combination and let firmware to repair itself.

Nope, oeminfo must be flashed via twrp or via some tools (for that is need root).
In that oeminfo file is stock oeminfo for installing VNS-L21C432B161 firmware.

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.

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,
I got a huawei P10 lite locked in demo mode (coming from a commercial center demo product)
I unlocked OEM, open bootloader, installed TWRP (hope mine is the last), and I forgot to backup demo rom before trying to install a stock.
At this time, I can :
- enter TWRP
- enter Huawei recovery (but does update anything in wifi)
- enter bootloader to use fastboot.
My model is a :
WAS-LX1A on C652B101
I downloaded stock firmware posted 4 days ago, (http://bit.ly/2mcaPDA) and choose France Bytel (WAS-LX1AC530B171).
I put the update.app in a dload folder in my microSD card. I tried to update with vol+ vol- power.
I got a failed error
I download too WAS-LX1AC530B170 and got the same problem. I supposed it was because it wasn't the same country code (mine seems to be 652 right ?)
Finaly I found a supposed compatible version on (http://bit.ly/2hqbOOW) named : Full Firmware-mf WAS-LX1AC652B130 and a second one named Ota Update-mf WAS-LX1AC652B130.
I extracted update.app and put it in a dload folder and did not succed in upgrading.
My question is : Have I forgotten something ? Or is this demo model locked to be upgraded ?
Finaly, is there a backuped rom usable with TWRP to be restored ? (like I saw with the P8 lite 2017)
Thanks in advance, for your help, and my appologies for my very poor english writings

Man i recommend backup only oeminfo, copy c432 and restore, then with servicerom b182(ds) or b183(ss) copy update.app + all was folders inside dload to dload folder inside sdcard
Don' waste your time with vendors+huawei

Thanks for your quick answer.
Can you give me precisions plz ?
- backup only oeminfo ? You means backup with my twrp ?
- copy C432 and restore, you means download a stock c432 and restore it with twrp ?
- 3rd part is ok

Yeah you make a backup with twrp in your sdcard(copy to safe place), then copy/replace c432 and press restore.

Ok fine !
Have you got a link for the C432 wich could be copied or restor with TWRP ?
thanks

Here you can download dual or single,
if you can acess to settings<about phone therw you have the imei(s), or too looking in the box https://forum.xda-developers.com/p10-lite/how-to/huawei-p10-lite-oeminfo-collection-t3670325

Ok !
Just to be sure, there is no problem to use a servicerom LX1 to repair mine wich is a LX1A ?

LX1A
X means some number such as 0 or 2.
L21 dual SIM.
L01 single SIM
A is mark for 4gb model.

Great ! All seems clear. I will try this evening and will come back to informe you about the results.
Is the old oeminfo usefull after a successful restoration or can I keep the one I used in your sample ?
