Yes, I did.. :good:
Updated and rooted!
Thanks, this method really works! http://forum.xda-developers.com/android/development/guide-install-twrp-root-systemless-t3325161.. I come from the ROM fRomFuture release KW45; really this update was a hard process in the first tries, then I want to share the details because the tools in various posts of P8 really did the miracle (he he):
1. First, I did flash the boot.img and the recovery.img from the release B200, more exactly from the ROM “GRA-L09_C432B200_Firmware_CEE&Nordic European Region_Android 5.0_EMUI 3.1”, of course, with the “Huawei Update Extractor tool”
2. I put the update.app of the B200 release in the dload folder in my external sd card, then I rebooted the device with the 3 buttons pressed (or best, firstly I have powered off this then I reset it with the 3 buttons pressed)
3. My GRA-L09 took quickly the update.app and finally this made the update, with a little message of error at the end, I don´t remember, at the 85%?, but this rebooted with a fresh installation of Marshmallow..
I update it with the ROM “Huawei_P8_Firmware_GRA-L09_Android 6.0_EMUI4.0_C432B321a_Bulgaria”, this detail in the attachments that the versions reliable for update are, the B200, B313 and B317
Finally, for the question of this topic, the only version of TWRP working for this release of android is the new_twrp.img in the forum linked at the first. I've tested others as the twrp-2.8.7.0-p8.img without success
Good luck! :good:

Did you change your phone's cust version? If u changed it you should dload a firmware (4/4.1) that match with your new cust
I rolled back with this method dozen times when EMUI 5 was not officiall!

Is that red message verification failed message?
If yes then please unlock the bootloader again even if it says unlocked. Then it will do factory reset and the red message will disappear.
You can then try to flash the stock firmware in TWRP. You can use B368 or B386 stock firmware from another thread and flash in TWRP. That is if you have TWRP. If you don't then unlock bootloader and then install TWRP using SRK tools. You can use SRK tools for adb commands also. Just type 000 on first page off srk tools and you will get into command prompt. Using that push the TWRP into your phone. ADB is very stable in srk tools and it will always identify your device. So that problem you won't have.
I couldn't find a proper rollback for AL10 . May be some one else can give if it is there for this model. If it was L29 model then rollback package is available and you can easily rollback using that in this type of situation.
If the flashing of stock ROM worked then you try to debrand your phone to L29 later. You will have many options then and L29 firmwares are more stable. I have AL10 which I debranded to L29 & I totally recommend debranding to C432 once your problem is solved
Do the above steps only if you are on marshmallow firmware.
Don't forget :good::good::good::good::good:
I created a al10 roll back for all al10 phones. It converts it to a DL0017 dual active sim. Message me for details how to obtain it from me .. MUST have twrp installed .

I'll change AL10 to L29C432 when I can do that

If you want to unlock bootloader through ADB?
Here are the steps.
In your phone go to settings - >developer options - > put usb debubbing ON
switch off the phone.
Press and hold the down button for 3 seconds & then connect it to the computer
It will then go to fastboot mode.
then open SRK tools
type 000 to enter the command prompt.
Type the following command
fastboot oem unlock xxxxxxxxxxxxx
In this command xxxxxxxx is your bootloader code. just replace xxxxxxx with your code and press enter.
This will unlock your bootloader & will do a factory reset.
In SRK tools there is an option for bootloader unlock but I think that is only if you are in EMUI 4.0 or EMUI 4.1 that is what I think may be anyone else who tried this option in android 7.0 can confirm but the adb commands will work.
I have enclosed screenshots for better understanding.
you have mentioned that you are in Android 7.0
Can you tell me your exact firmware that you have on your phone at the moment?
After you get rid of that red message. Your bootloader is unlocked.
There is Erecovery process - > steps below (but there is a problem with this process)
1)Switch off the phone.
2) Press and hold the volume up button and then connect your phone to computer or charger. Yes charger. Then you can download stock firmware through your WIFI - > this will also install stock firmware. But I think this won't work because of unlocked bootloader
So once again install the TWRP for Android 7.0 I think it is Twrp 3.0.2 or Twrp 3.0.3 - > this is definitely for nougat.
ADB command to install twrp recovery is
fastboot flash recovery twrp.img ( rename the TWRP to twrp.img ) in the adb.
Try to flash the stock firmware zip files in TWRP.
Here you have two options - > You can either try flashing B386 files (only one zip file) or B562 (android 7.0 - > 2 zip files - first update.zip and then the other zip file)
If you are successful in this step then your TWRP will be overwritten with stock recovery.
That is ok. don't worry. Kangvip ROM is pre-rooted ROM. So you will get root in the end. For now its ok to be on Stock at this step.
Stock Recovery + Stock ROM + bootloader locked -> then you can dload back to EMU 4.1 using B386 firmware.
Then you can unlock bootloader (again) yes its a pain + followed by TWRP + ROOT - one after the other in SRK tools its all there. you can use the options in SRK tools this time.
And once you have root again.
Take backup and save it on your SD card. (except DATA , take backup of all options listed there, why? bcoz if you include data - > it will increase the backup size and it will take more time.
*Disclaimer* -> Very tricky & risky process - proceed with caution & full attention
Then - > you can debrand - > to C432 -(debranding is very tricky process, so keep your backup handy) This should be done very carefully because any problem here means you might find less space on your internal memory. Then you will have to restore that backup to get back your space.
Here is the link to excellent tutorial by somboons Watch it carefully.
https://www.youtube.com/watch?v=JZVsIKtdgV4
Just follow that as it is for debranding from AL10 to L29-C432
I am very very sorry for all these confusing and tricky steps. Please proceed with caution when you are doing the debranding process. Do not get diverted during that process.
Yes I did all this when I debranded my Huawei Mate 8 AL10 to L29. I had lot of anxious moments, doubts & my mind started playing tricks if mate 8 was dead on few occassions. But in the end my phone prevailed. Now I am happily using L29 - Kangvip B577. That is where I want you to land up in the end.
Do not worry and do not panic any time. Be prepared to face few challenges during this process. I will help you but please share your experience and follow the steps carefully.
During debranding you might have your phone rebooting or something might happen. That time do factory reset and continue from where you left off. If you get red message - > then you have to unlock bootloader. Otherwise continue.
This whole process will test your patience & consume time. So I hope you are willing to do this. Its worth it. I learnt my lesson, I am never buying chinese version of Huawei phones/tablets again. Only European models from now onwards.

TWRP 3.1.0.2 is actually used for flashing nougat firmwares.
Which firmware are you on right now?
Are you on nougat or marshmallow? Please provide the full firmware build number.
if your phone is on marshmallow.
TWRP version depends on your firmware.
If you are on EMUI 4.0/4.1 then pls use the TWRP 3.0.2
you can use SRK tools to install that TWRP if you are on EMUI 4.0/EMUI 4.1
Install that version. Then
Factory reset
Flash the B386 zip file in TWRP.
You can get the B386 from here https://forum.xda-developers.com/showpost.php?p=69331930&postcount=1338
If your phone is on Android Nougat.
Then you have to use dload method.
Unzip the B386 zip file.
Put the update.app in the dload folder inside your external sdcard.
Go to your dialer
*#*#2846579#*#*
Select "software upgrade"
then Select - > SD card upgrade.
And then it will reboot and install the stock firmware.
This thread has all the Stock firmwares.
https://forum.xda-developers.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727
Hope the above steps solve your problem. If not, then we will try something else. please answer all the questions to help you better especially your full build number (firmware version).

Since you are on nougat with test keys, try to flash the latest nougat firmware on your phone model NXT-AL10 (Try flashing firmwares using TWRP )
Link for the firmware
link 1 https://mega.nz/#!Y4IVEbxY!7C8u3FP3V8eAV4jVNmbRUfj2W1nc8p5gMtaScVmzeA0
if the link 1 doesn't work then try link 2
link 2 https://mega.nz/#!U9ZkTZzI!fbPnyDIxCGGFkiGxtF3SMicLqmTDNTq8SG8fVw8lfz8
download & flash it using TWRP.
Once you finish flashing - you should have android nougat stock B584
Go to settings - > about you should see that B584. in build number.
If your build number is showing anything other than test-keys then you will be able to use dload method or Hisuite method using PC.
Now if IT IS showing B584, then you can dload to B386. then unlock bootloader -> TWRP using SRK tools - > Root - > and then debrand to L29C432. - > this is the road map for you. we will go through this only after you succeed in the above steps.
Try the below steps only if the above steps don't work
if you want to flash the nougat recovery
then unzip the zip file in link 1.
Use Huawei update extractor software HuaweiUpdateExtractor_0.9.9.3
and then extract the recovery.img from the update.app file.
now
switch on usb debugging in your settings.
switch off the phone
press & hold volume down and then connect to phone to laptop
put the extracted recovery.img file in the same folder as the SRK tools
open SRK tools
type 000 to enter command prompt
type fastboot flash recovery recovery.img
(please remember all these steps that use adb commands come with element of risk. so please proceed with caution and go slow. Proceed with these steps only if you know what you are doing otherwise do not proceed)
Try the TWRP steps first and see if that will resolve your issue before flashing any stock recovery. If your flashing through TWRP then it will install stock recovery & stock ROM.
Please share your progress.

Glad to read Ur kind words but V have a long road ahead. So let's fix ur phone :good:
Answers
1) Yes, you can format DATA before flashing this zip file. you can also do factory reset before flashing the zip file. (Remember we are doing this step only to get ur phone out of that test keys & this firmware is not ur final firmware that u will use. )
2) I was searching for a firmware that u can flash on ur phone and I found B584 and felt this might help. The guys in the other thread mentioned it as full firmware. After u flash this firmware, check in settings - > about - > build number if it is anything else other than test keys then u succeeded in this step.
Goal of this flashing of B584 is only to get rid of that test keys in build number. Once that is gone then U can downgrade to B386 using steps in my previous posts followed by the road map.

Plzzz help im stuck I want to rollback my huawei p9 lite VNS-L31 where its build number is NRD90M(test keys) to marshmallow 6.0 help don't know what to do . Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help
Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66015/f1/full/update.zip
And again extract and move the files to dload folder on your sd card.. Install with 3 button method.
Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤
this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.
Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.

hello guys! im currently on lineage os 14.1 by meticulus, i wanna revert back to stock mm but i cant. i flashed the custom rom from mm using twrp recovery by meticulus, but now i cant even boot into erecovery! can you pls help me!:crying: DLOAD method doesnt work!
Hi all,
i own a p9 lite that was on Nougat VNS-L31C432B381 and i decided to rollback to MM. Following Huawei website instructions I downloaded two packages (rollback package and MM) and with 3 buttons method I flash first the rollback package and then MM. All went right and the ROM was stable. After a while of testing (that's why i went to MM), I decided to upgrade to nougat again. From updater it download and install the new android version (1.25 GB). After reboot I noticed that some system app was missing (file manager first). At every reset/factory reset some system app disappear. I repeated the procedure to rollback and upgrade again with the same result. The only way to use the device was to reflash MM and don't upgrade. Here some information I found:
- my starting version was Nougat VNS-L31C432B381
- now I'm on VNS-L31C432B160 (B160 isn't for dual sim? i have the single sim version) stock recovery bootloader locked
- updater try to install VNS-L31C432B370 (instead of B371?)
- if I try upgrade throught updater SN became something like ndr90 test key
- I tried to restore data,syste,vendor,oeminfo ecc.. from backups made with TWRP in Nougat (maybe wahile i was on MM, I'm not sure). It show the correct SN but ROM was still unstable
- I thought to try install full Nougat ROM but i didn't find any package
Can someone help me?
Thank you
The B37x update that the phone automatically finds after rollback doesn't work and will take you to ndr90 test key as you found out B160 is dualsim so you should flash the 161 one. Then use this guide to update through firmwarefinder/proxy https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-b388-nougat-maybe-b381-guide-t3612072
If you want to unlock your bootloader you can also flash B3xx through twrp. If not, the guide above works fine.

Hi Mara-X and thank you for you answer.
After I write the post i found the B161 package and i decided to give it a try. After flash (all ok) I launched updater again and it download the B371. The update went well and now i'm updating at B381 again throught updater. I think, when it was done, i'll factory reset the device for a clean install. So it seems the problem was B160/161 -single/dual version.
SOLVED: please check my 2nd post.
Hello guys,
I would like to upgrade my P9 Lite L31 from M to N official. I've tried the past few days but it always ends up with "NRD90M test-keys" on build number and missing apps. I have read A LOT of threads/posts about this issue, really everywhere, but I can't figure out how to update my device without problem.
Also I do know there are some Q&A threads/GUIDES/HOW-TOs in the forum but I don't find the right procedure for my case.
I assume it's because I've flashed the wrong package or forgot something in the procedure...
I've followed this GUIDE by @simo255: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932
Here is my info:
P9 Lite VNS-L31
3 Gb RAM
Build: VNS-L31C900B151
EMUI 4.1.1
So, I'm on C900B151 and I'd like now to upgrade to C432B380 (or C432B381 ?) (or above if available).
If I understand well, the correct procedure is:
1- unroot (necessary?)
2- change from C900 to C432, by flashing an C432 OEMINFO.img through Meticulus TWRP (v4)
3- flash the latest Nougat update.zip package (B370/B371 or B380/B381) through Meticulus TWRP (v4)
4- flash the latest data full EU zip (B370/B371 or B380/B381)
5- reboot
Is it OK?
At steps 3 and 4, do I have to get UPDATE.app for B3xx and use the dload method instead?
FYI, I didn't follow step 2 when I tried, is it the culprit of my CUST errors in TWRP/"NRD90M test-keys"/missing apps problems? Or is it because I've flashed B370 instead of B371?
A few questions:
1- Is it a problem to currently run B151 firmware for my L31 for the Nougat upgrade process? I've read that the last digit means dual SIM or single SIM. I think I have a single SIM version but I'm not sure... How to know for sure? Sorry for the dumb question
2- If I don't follow the procedure above but if I relock my BL and then check for updates, do you think I will get a Nougat full OTA for C900 (C900B151 > C900B3xx)? Is it really necessary for me to change from C900 to C432?
3- In any cases, would it be possible to upgrade directly from B151 to B38x? Or do I have to go through B16x or B37x?
4- I can't figure out how to get the correct full OTA for Nougat, the one bigger than 1,9 Gb. I always get 1,25 Gb package through OTA update in settings, even when I'm running C432B160...
5- Is it possible to use Firmware Finder to update from B151 directly to B38x (or above)?
I already tried to flash a B370 update.zip and data full EU (from this GUIDE) but I have error about CUST in TWRP and as already said, then I get "NRD90M test-keys" on build number and missing apps after reboot.
After this, I successfully downgraded to C432B160 (maybe it would be better to downgrade to B161?) and I get the B370 OTA (1,25 Gb), but as you know it's not the FULL OTA... So AGAIN: "NRD90M test-keys" on build number and missing apps.
Sorry for the long post but I find really hard to flash/update stuff on this P9 Lite. I'm really confused. I was before on a Samsung S3 LTE and it was easier...
Any advices?
Thanks in advance.
I solved my problem!
My mistake was to install build VNS-L31C432B160 instead of VNS-L31C432B161, that's why OTA available was not the correct one (1,25 Gb instead of 1,99 Gb)
B160, B370, B380 are for dual SIM
B161, B371, B381 are for single SIM
I have a P9 Lite L31 SINGLE SIM
I was on previously on build VNS-L31C900B151 and I'm now running build VNS-L31C432B381 official and everything is working well.
The steps:
1- Download Update.zip of VNS-L31C432B161 (size around 1.6+ GB) (I've found it and downloaded it with Firmware Finder)
2- Extract the UPDATE.APP of the ZIP with 7-zip or similar and copy it on External SDCARD in a dload folder
2- Make sure to be rooted (Bootloader unlocked, TWRP v4 by Meticulus installed and SuperSU flashed)
3- Flash OEMinfo.img and custom.bin for C432 Single SIM (download link: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873, from this thread: https://drive.google.com/drive/folders/0B3CRCPqinridRXNPdDNuM2g5dTA) with Toolkit (download link: https://forum.xda-developers.com/devdb/project/?id=16538#downloads from this thread: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873)
4- Reboot > It asks for decryption key (I entered a wrong one because I didn't even know the code) > it fails to decrypt and then ask for factory reset
5- Factory reset fails (I don't know why)
6- Reboot on Android > build is now VNS-L31C432B151 (it changed from C900 to C432 thanks to the OEMinfo.img and custom.bin)
7- Shutdown the phone
8- Start the phone with 3 buttons method: vol- ; vol+ ; power
9- Wait a few minutes L31C432B161 to be installed > It reboots and you're now running L31C432B161
10- Search for OTA in ROM settings > You will get L31C432B371 > Download and apply the update
11- Wait a few minutes L31C432B371 to be installed > It reboots and you're now running L31C432B371
12- Search for OTA in ROM settings > You will get L31C432B381 > Download and apply the update
13- Wait a few minutes L31C432B381 to be installed > It reboots and you're now running L31C432B381
14- Done!
So i have the same problem.
I've the L21 Dual sim model (2GB) and i tried to update.
Messed up with firmware finder and ended up with a wrong update. I've managed to get back to L21C432B160.
What version do I pick with Firmware finder? Or do i need to flash another OEMinfo.img en custom.bin first to get an update?
I don't want to end up with beta firmware or something messed up so I keep getting future updates. I don't understand why the OTA update is still here on my p9.

Which oeminfo.img and custom.bin did you flash lately? Is it your own files or from someone else?
And you say you are currently running L21C432B160 but which OTA version is showing up now in ROM settings? Which size?

If you want to get OTA updates, you need to have your bootloader locked. Is your bootloader currently unlocked?

Yes. But the problem also occured when it was locked.

I meant once you run full working Android 6, you have to go in Android settings, in a menu called something like "system updates" or similar and you should see if a newer Android version is available, meaning Android 7.
I'm running Android 7.0, so I can't show you screenshots from Android 6,sorry... Here are 2 screenshots from EMUI 5.0 (Android 7) in case it could help.
