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

Hi, I need help, I have the Chinesse version of mate 8( NTX AL10), and I installed the 577 version in HiCare, but Im having too many problems and I want to rollback to Android 6.
Someone can show me the way? I tried to install twrp recovery (I have the bootloader unlocked), and I couldnt format data because I couldnt access to internal storage in the recovery.
Thanks

maybe u have to do a factory reset first. if u cant do it with twrp try to enter the stock recovery and do it before flashing. hope that it works this time.
about me, i was on nougat beta, twrp gives me too much errors when i want to format data and system, i installed stock recovery and did a factory reset and i used dload folder, now im on EMUI 4.0 (B180)
dont worry every problem have a solution. good luck
Posted from Mate 8.

Or with Rollback UPDATE.APP.
My Mate 8 is L29C636,i convert to AL 10 with B577 and go Back to L29 C636B211 without any Problem.
I can upload the UPDATE.APP later 92mb.

Use HiSuite via PC and roll back by updating to earlier versions! It's simple

And how did yo do? Can you explain please?

Copy the Rollback UPDATE.APP in dload Folder in Micro SD.
Change oem.info and custom.bin from AL10 to L29.
Boot in Bootloader and Flash Stock Recovery and reboot
This make Automatic a Factory Reset and Lock my Bootloader
Go to dailer and use this code *#*#2846579#*#* and go to 4.Software Upgrade.
After this Procedur copy my Original Firmware for c636B211 in dload Folder and make the same Procedur with *#*#2846579#*#*
After flashing the Firmware i am on L29C636B211
But you have a AL10,i think you flash the Rollback Update App
This Roll Back flash to Emui 4.0 and not to 4.1
After flash the Rollback,Download a Firmware for your AL10 with Emui 4.0 and flash this Update App via dload *#*#2846579#*#* here
This Methode can use with locked bootloader
Download Rollback
I think this works
If not take what was described above

p9 lite stuck on huawei boot logo

My p9 lite is stuck on the huawei logo, its been a week now. it all started when I flashed a wrong update.app (i mistakenly flashed the rollback update.app while i was on b161)
now I cannot use the device anymore, i can only get to bootloader mode but cant flash anything
help

I had the exact same problem. I got out of that situation by rooting the phone, and re-flashing it.
However I already had the unlock code handy. If you don't have that then you are mostlikely f'ed.

My bootloader is unlocked yet I am unable to fastboot flash anything as i get errors.

HEY! I've done the same thing yesterday But now phone working great! I find the way
1. Download C432B160, Huawei Extractor and SRK Tool Huawei
2. Prepare your unlock bootloader code
3. Unpack UPDATE.APP by Huawei Extractor (You need files: boot.img, system.img, recovery.img, cust.img)
4. Go to folder SRK Tool Huawei -> Command
5. Put *.img files to Command folder
6. Put UPDATE.APP (Not extracted) on your sdcard in folder "dload"
6. Hold Shift + right right mouse button "Open the command line here"
7. Plug your phone in fastboot mode (vol- and power button then fast plug USB)
8. Type in cmd "fastboot devices" (Now you probably see your device)
9. Type:
fastboot oem unlock xxyourfastbootunlockcodexx
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img (that command takes 2-3 minutes)
10. Unplug Your device
11. Hold vol- vol+ and power button, it will install UPDATE.APP from your sdcard
12. Done!

I'm stuck at "6. Hold Shift + right right mouse button "Open the command line here"" I have no idea what to do

You have to hold the "Shift" button on your keyboard (under Caps lock), and click on the right mouse button in the folder. Then in the menu, choose "Open the command line here"

Yes, you can't flash C432B160 if your phone is branded by operator, the flashing will always end at error. Flashing oeminfo.img and Huawei firmware is fully legal and you don't loose warranty. And debranding is a good thing because (in future) you can download faster official Nougat.

okay

Alright so let me explain my situation properly (I'm a big dumb-doofy-doo so i'm not even sure if my phone is branded) I bought my phone off amazon last year and 2 days ago I made the mistake of trying to update it to Nougat using http://www.droidviews.com/update-huawei-p9-lite-manually-official-android-7-0-nougat-emui-5-0/ and the files for build number VNS-L22C636B360 however my build number is VNS-L22C636B101 (Huawei P9 Lite). using the first file called "update.zip" I tried upgrading but it said software update failed. I turned on OEM and tried using "update_data_full_VNS-L22_hw_spcseas.zip" to update. it worked but I don't think this was the full update as it rebooted and I was greeted by Huawei eRecovery which had three options: "Download latest and recovery" "reboot" and "shut down" so naturally I chose the first option. It however ended with "Getting package info failed". I tried it over and over but it didn't change. so this is where I because frustrated, and stupid, and factory reset my phone. it didn't make a difference. same eRecovery prompt (but did the reset take off OEM??) I took out my SD Card and replaced the Update.app with another one (I cant remember which I was sad but I definitely complicated matters more by doing this) and I came upon the same problem the person who made this post: stuck on Huawei logo. if I power it off it will vibrate and boot back up on it's own to get stuck on the Huawei logo thing (it wouldn't even do the pretty flowy smoke thing) so because of this it does not respond to the 3-button force update anymore idk why the only mode I can get it into successfully is fastboot mode but even after following the step by step answer I cant get it to respond to the 3-button force update (I also dont have the exact firmware for my build number) I did skip the bootunlocker steps because I dont have a product id or IMEI to generate a code from the Huawei website. in fastboot mode however it says "Phone Unlocked" and "FRP Unlock"
I dont know what to do... I think I need the firmware but I cant find it specific to my build number VNS-L22C636B101

First of all you must have your bootloader unlock code...
You wrote that you get error on flashing by fastboot probably "Command not allowed" because, your bootloader is locked (Yes it's only display "unlocked" I also got on that )
If you don't have code you can't do anything, sorry. You must send your phone to huawei store on warranty.
You don't have phone box?

ya

Mine was solved by booting to fastboot and did fastboot OEM unlock "unlock code" then fastboot flash recovery TWRP.img

VNS-L31 P9 Lite Bricked

Hi here !
I own a VNS-L31
Bootloader is unlocked
I tried to update to Android 7, but I bricked it because of the recovery was a TWRP for Android 6
Now, the device is bricked to the loading screen.
So, I tried with fastboot to flash files.
fastboot flash boot BOOT.img -> OK
fastboot flash recovery RECOVERY.img -> OK
but :
fastboot flash system SYSTEM.img -> I get the same error :
target reported max download siez of 471859200 bytes
sending sparse 'system' <451240 KB>
OKAY ( 20.390s)
writing 'system'...
FAILED (remote: sparse flash write failure)
finished. Total time: 20.720s
Click to expand...
Click to collapse
I tried with the toolkit to flash the 4 images, but I always get the same answer : no device detected! blabla
However, the drivers are installed. I installed HISuite before all these...
What I can do now with myt brick :
boot to fastboot mode
boot to eRecovery (but no way to download anything, I doesn't work...)
nothing else.
I read this forum and all posts relative to P9 Lite brick, but I can't do anything until the SYSTEM.img file is written to the phone
Thank you for reading me

1. Download adb drivers...search on Google adb all in one installer it's on xda forums.
2. Download adb minimal package also search on Google and it's also on xda.

Hi
ADB drivers are already installed, by the method you given.
I can use ADB, the P9 is recognized.
The problem occurs always and only with the toolkit. My device is not recognized with it...
I can flash recovery, I was able to use dload, I pushed a Nougat firmware, and now, I have a TWRP recovery, but the phone is always blocked.
With the recovery, I noticed another problem. As you can see on the picture, partitions cannot be mounted. I don't know why...

This device is really hard to flash some firmwares....
if you're out of options you can try to use DC Phoenix it cost 10-15$ i believe : https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial

I would try to re-flash Nougat by the dload method first. You could also try to flash VNS-L31C432B160. For some reason it is more readily accepted by a bricked VNS-L31 than other full firmware.
If that fails, I'd resort to DC Phoenix.

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.).

Thanks for your help. Is the VNS-L31C432B370 firmware compatible with single sim?

No, that's why I gave you the link to oeminfo dual Sim. If that's a problem for you, try looking for the B371, I didn't find one.

It's not a problem for me. What problems could I encounter if I use a dual sim firmware?

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.

I've installed the с432b370 update correctly, but I can't flash the data package (update_data_full_VNS-L31_hw_eu.zip).

it happens sometimes...
Just to be sure - reboot to fastboot mode and run command:
fastboot oem get-build-number
and post result.

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!

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
