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 !

I can ont flash the boot.img. I get this error:

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

L31- Brick after downgrade Nougat to MM

Hello !
Last week, i get the nougat beta firmware for my P9Lite (L31)
Today, when i want downgrade to MM, my phone was bricked.
I tried all methods i see on the forum but the phone don't start anymore.
Install via fastboot : FAILED
Install via eRecovery with update.zip : FAILED
TWRP NOUGAT B2 flash : FAILED
If you can help me please, thanks in advance !

unlock bootloader.

I have exactely the same problem, i can't do anything, i have the bootloader unlock, i have acces to TWRP nougat, bug the system don't boot ;( Please help !
I have flash system via fastboot, Failed.
I have no phone now

i also experienced that...this is how i resolved it:
1. Sideload the OEMinfo for VNS-L31 dual sim (or whatever version of P9 Lite you have)
2. Unpack the MM update.zip for the appropriate version of P9 Lite you have.
3. Create a folder on your sdcard called "dload'
4. Put the UPDATE.APP from the unpacked zip file into the dload folder.
5. While phone is switched off, put it into download mode by simultaneously pressing volume up + volume down + power button.
6. Should downgrade to MM.
7. All done!!!
Care must be taken as the OEMinfo is very P9 Lite version specific (ie, Dual sim and single sim).

OEMinfo for VNS-L31 can be found here http://www.htcmania.com/showthread.php?t=1261335
Sideload is a function, rather a command used in adb. Sideload is used to directly flash a zip onto your phone...Simply put the zip file into the adb folder. Thereafter enter TWRP, click on advanced and then click on sideload. Start the adb server and use the command : adb sideload <enter name of zip file here> and hit enter.
Example : adb sideload OEMinfo.zip

Did you check if your device is able to connect via adb? use command : adb devices.
You need to install the UPDATE.APP via the three buttons, not the entire zip. It is crucial to flash the OEMinfo. Since you are able to enter TWRP recovery, try flashing the OEMinfo via TWRP.

No conection. Just fastboot mode and twrp. I think the adb sideload not working. The three buttons just show the huawei pticture and stuck on it. Maybe a twrp backup of vendor partition can help, but i don't have one....

Which original one though? I've been trying and downloaded any Full firmware I could find using a firmware finder, for my VNS-L31 but using the force update method in download so far all of them return an error: Incompatible with current version. I have also tried the fastboot update and separately flashing each file in the update.app . None work so far. I keep trying.

If you're on Nougat, try flashing it's files through fastboot. It worked for me, MM system.img gave me an error, but nougat flashed fine.

I believe ur in nougat beta... Just flash oem info and flash again the nougat from there you can start again and downgrade peacefully

your bootloader is locked

Thank you! I followed the instructions here with a slight variation. Because trying to install the update.zip file always gave me errors I extracted the update.APP with the update extractor tool and flashed cache,system,boot with fastboot. Then I opened the custom recovery, installed the other zip file and continued as instructed.

Stock ROM to UPDATE IN 2021

Hello, good day. I just wanted to ask, (Im using custom rom now and my old backup is nowhere to be found) If I am going to flash my device to official stock rom, like if I flashed the older version (lets say the MM) can I still update my device today (up to nougat) through OTA update?
i think huawei cloud is the site where we download OTA updates from but I think is already dead.
(sorry if my poiint is confusing, I just really don't know how to explain it clearly)

So if I not mistaken, your build number is VNS-L31C185 EMUI 5 (correct me if I'm wrong).
Firmware finder and Huawei old server are down, so download service ROM.
IMO now you have two possibilities:
A) flash Service ROM using dload method, guide can be found in ReleaseDoc folder. The process will erase all your data and lock the BL again!
B)
- from downloaded ROM extract BOOT.img
RECOVERY.img
SYSTEM.img
CUST.img via 'Huawei update extractor' , follow Guide
(Note: CUST.img on Nougat can be found in the second archive)
- In fastboot mode flash extracted partitions using commands
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
- fastboot reboot
- Factory reset in stock recovery

So if I not mistaken, your build number is VNS-L31C185 EMUI 5 (correct me if I'm wrong).
Firmware finder and Huawei old server are down, so download Service ROM
IMO now you have two possibilities:
A) flash Service ROM using dload method, guide can be found in ReleaseDoc folder. The process will erase all your data and lock the BL again!
B)
- from downloaded ROM extract BOOT.img
RECOVERY.img
SYSTEM.img
CUST.img via 'Huawei update extractor' , follow Guide
(Note: CUST.img on Nougat can be found in the second archive)
- In fastboot mode flash extracted partitions using commands
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
- fastboot reboot
- Factory reset in stock recovery

Oh yeah. I just figured it out but had to rename that to update.app so update extractor can accept the file. Thanks by the way.

for now SYSTEM and CUST takes time to finish extracting.

Try command
fastboot erase userdata
and reboot.
Check your current build number etc.

Bro try this way out...
Download and install TWRP (if possible) and let me know
Upd.: nevermind, I forgot you don't have an sd card,.
Upd.2.: without SD you can try to flash Service ROM (or B361 firmware) using TWRP and sideload method. Unfortunately, sideload is Greek to me , so google it.

I can still go fastboot mode and install everything without any errors but I don't why, it confuses me that let say I just flashed recovery (custom or stock) but when I'm going to access it (volume up + power button) phone just vibrates twice but nothing will happen.

Flash TWRP over eRecovery, run command
fastboot flash recovery2 twrp.img
fastboot reboot
when a yellow warning appears on the screen, pres and hold Vol Up for 3 sec.
Edit: maybe your data partition is formatted with f2fs (after installing Elite ROM) , it should be ext4. I'm out of ideas bro, sorry.

No problem. I think I hard bricked my phone, I just got boot logo and fastboot but I can't find any fix or solution or anything to do with this.
Flashing recovery or recovery2 finished w/o any errors but I can't boot to recovery.
Thanks for your help by the way. I appreciate it! Kudos and have a nice day. Keep safe.

IMO you only need an SD card and flash the Service ROM.
