P9 Lite cannot flash stock firmware

I have a Huawei P9 lite. (VNS-L31 dual sim) . I tried to install medrom 3 and after flashing, phone didn't boot up. So I flashed b161 firmware again using 3 button method and phone booted up. Then I realized I couldn't add my google account. After searching on xda I found a method to fix that.(flashing oem info ). But after doing that, when the phone boots up after the huawei logo the error message which says "your device has been unlocked" has become red.( Usually it's yellow). And in about phone my model number has been changed to something like hi6250 or hi650.( Can't remember the exact thing). Then I tried to reflash my b161 firmware using 3 button menu and voila. It says incompatible version. I can't flash it. Then I replaced my build prop with my friend's phone's build prop. But unfortunately it has the B151 version. Though I have B161 version installed, my about phone says it has B151 version. And I can't flash stock firmware using twrp or dload method od any how. Please help

That's normal if the message is red, it means that the bootloader Will be relocked.
Now for the build prop, download b161 version, use huawei firmware extractor , extract boot.img system.img and cust.img
And by fastboot type :
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot reboot
And voila, b161 is installed in your phone !

If fastboot say "FAILED (remote: Command not allowed)", its because your bootlaoder is locked, reunlock it !

In TWRP it says unable to mount Data :/

Unable to read/mount data says your encryption key got changed by something, whatever. You need to Wipe Internal storage and flash twrp again ( I recomment matic`s ) Reboot to recovery again, if you got one, flash a flashable fw via twrp. I Dont know if the stock recovery Accepts a fully wiped intern storage, i guess not and it declines the update.app method.
In the best case for sure you recover an older backup to get the Same enc. Key back

how to recover?

Since I lost everything from the boot to the recovery to the system part to anything, i haven't been able to boot the phone;
I can access erecovery but when I try to recover the phone it stops at downloading and then says couldn't connect to servers so that's dead;
I can access TWRP but when I try to flash MM, it returns errors saying that it couldn't mount partitions (Vendor, cust and other...)
I can access fastboot mode. Some people suggested that I should try recovering using dload but the transfert rate to the sd card is taking forever;
Now I extracted everything from update.app using huawei firmware extractor (see http://imgur.com/MWeCCXi ) what should I flash (via fastboot) and in what order?
I would really appreciate the help.

By Nougat I assume you mean the file that has been digged out somewhere in the web and that is floating around here in the forums?
Well we all don't really know what this build exactly is, which makes it very hard to reconstruct your errors and give you advice... I would never flash that but okay, that's why we are here
Do you have a TWRP backup that you can restore (and if no, maybe somebody can upload you a clean TWRP restore file)?
Have you tried flashing CM / AICP?

Hi there. Earlier I spent a few painful hours in the same boat you were in. I've managed to get back to a fresh install of the Nougat build from this thread, but can't seem the downgrade to MM using the (translated from Spanish) instructions found here (linked from that first thread). How did you manage to get back to MM?
(I should add that I tried to flash boot, system and recovery via fastboot without any success).
Cheers

May god have mercy on your soul.
For the downgrade, I didn't use the b161 directly. I flashed some oeminfo provided in the same folder as the TWRP. Then used b150 ans the three boutons method. Worked like a charm.
Hope it will help you downgrade your phone.

I have the same problem, someone could explain it to me step by step, please

@haky 86 (I'm assuming you were the one who wrote that guide) is the guide for updating from nougat to oreo or updating an Oreo firmware to the latest?

Updating Huawei P9 Lite h3g/it to Nougat

Hi everyone. I've already rooted my Huawei P9 lite and now I'd like to update it to Android Nougat.
I tried to install different versions of firmware through OTA, but none of them worked out well. I'm starting to think that this is due to the firmware which are not compatible with my device, and considering that my build number is quite uncommon, that could also be the case. I read from some threads that I have to unroot and lock the bootloader again in order to perform the update, but honestly I'm too lazy right now and I'd prefer to keep my device rooted if it's possible.
Does anybody know what could I do in this case?
OEM Build Number: VNS-L31ITAC555B160
OEM Product Model: HUAWEI VNS-L31
Vendor Country: h3g/it

Hi,
you have to rebrand to the Global version (IMO) :
1. install TWRP 3.0.2.0 , Link
2. In TWRP flash C432 oeminfo.zip Link
3. Go back to TWRP's menu without reboot
4. Follow instructions (from step 3.).

It has no effect on the phone's functionality.
Btw, there's B371 Link ,but it may be password protected . For Single SIM firmware use this Oeminfo.zip

I tried to flash the C432 oeminfo, but after rebooting a black screen with red text appears and I can't unlock my phone because it's unable to decrypt the internal archive. Same thing with the singlesim oem info.
Also I can't mount the Internal Storage from TWRP because it results as 0 MB.
The only way I found to solve this issue is by restoring the original oeminfo from a previous backup.

Okay, now read carefully:
1. Download TWRP for Nougat Link
2. Flash it over eRecovery (!)
using command:
fastboot flash recovery2 twrp3102.img (recovery2 , not recovery!)
3. Flash stock Recovery Nougat
Link use:
fastboot flash recovery xxxxx.img
4. Reboot, when yellow warning appears, press and hold Volume Up for 3-4 seconds, you should boot into TWRP
5. In TWRP select Wipe - Format data - yes - confirm. Go back - Reboot - System
6. And again, after yellow warning Volume Up and reboot TWRP. Now you can try install second .zip file hw_eu.
7. Reboot into Recovery and do factory reset.
Good luck!

5. In TWRP select Wipe - Format data - yes - confirm. Go back - Reboot - System
6. And again, after yellow warning Volume Up and reboot TWRP. Now you can try install second .zip file hw_eu.
7. Reboot into Recovery and do factory reset.
Good luck!

Hey, I'm not doubting your instructions! Hahaha.
I'm just asking, what should I do now? I can't flash TWRP to recovery2 if it doesn't allow me to commit any command.

Restart your phone, if the BL is really unlocked, after restart appears on screen yellow warning. Fastboot sometimes lies...

Okay, finally I flashed TWRP. After restart, I pressed Volume Up key but it remains on the yellow warning screen with the text "Your device is booting now...".
Edit:
I solved this by installing Venus TWRP for P9 lite. Then, I followed all the instructions and updated to B416 through dlaod, and later to B418 through OTA. Additionally, I had to unlock the bootloader again and root.
Now I have a fully-functional P9 lite updated to Android Nougat

Hi everyone. I've already rooted my Huawei P9 lite and now I'd like to update it to Android Nougat.
I tried to install different versions of firmware through OTA, but none of them worked out well. I'm starting to think that this is due to the firmware which are not compatible with my device, and considering that my build number is quite uncommon, that could also be the case. I read from some threads that I have to unroot and lock the bootloader again in order to perform the update, but honestly I'm too lazy right now and I'd prefer to keep my device rooted if it's possible.
Does anybody know what could I do in this case?
OEM Build Number: VNS-L31ITAC555B160
OEM Product Model: HUAWEI VNS-L31

Which process did you follow for the root?
