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 .

Yes it is red message verification failed message.
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.

[SOLVED] Need help to upgrade from L31-C900B151 to latest Nougat build

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?

Haven’t flash any of these files yet. I dont have an ota in upater right now. That is The probleem. Only with the firmware Finder i can get updates but i dont know which i should pick

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.

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!

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.

[TUTORIAL-easiest] Rebranding to L19 C10 (Russian, EU) for Oreo update + video

Hi, I will show you the most easiest way to get oreo update (emui 8).
you must have installed twrp and unlocked bootloader.
1. Download this https://forum.xda-developers.com/honor-8/development/tool-srk-tool-huawei-bootloader-root-t3470823
2. Press 7 then 9, next 7 and 5.
3. Now download 2 files: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1276/g104/v64076/f1/full/update.zip thanks to @jithendrav83
https://www.hihonor.com/uk/support/details/index.html?DOC_ID=92135 <- first
4. flash it by dload method
thats all. Now update your phone by huawei built-in updater or firmware finder.
But for me the best option is unlocking bootloader again, root then flashing by this tutorial: https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306
(method 2)
VIDEO OF EMUI 8 ON HONOR 8:
https://www.youtube.com/watch?v=VVe9gsyVxd0&feature=youtu.be

As you wrote, then the update will wait forever.
At this location you can, because. on the Russian version in the folder "cust" is your region. I recommend that you visit the Russian forum 4PDA.RU

Hi,
Would this work on Honor 8 single Sim device (I've FRD-L02)?

Yes. You can rebrand L02, L04 to L09 without any issues.

As per my guide, you only lose it if you're rebranding to AL/DL (chinese). Rebranding from L02, L04 to L09 is perfectly safe (I'm running L09C10 on my L04)

So best way to get Oreo on L04 is to rebrand with this method and redlotus to the Russian EU firmware and everything will work?

Hi,
I rebranded FRD-L02 to FRD-L19C10 and tried above steps. Installed Oreo by redlotus method. But got "data corrupted" menu and I formatted data. Now phone won't boot. Then I tried unlocking bootloader and phone booted. But sw version still shows B95 and its on Oreo. Looks like cust/region part is not flashed. Tried installing Twrp 3.2.1.0 and the one in Multi-tool, but phone won't boot to recovery. Its going into error mode. Any suggestions appreciated. Thanks.

If you look at the XML File you used for the RedLotus method, you can see that there are two versions in it (L09C10 and L19C10). I suppose that's the reason why it's bugging for you.
Don't know for sure though. Trying that method now too, will report back if that's really the problem.

I dont have windows pc but Mac. How can I rebrand?

Why redlotus? Do it as in tutorial. Download three packages then flash by tutorial in my thread.(link is there). I meant flashing by modified Huawei recovery.

To rebrand, you need an unlock bootloader.
1. Download the C10 oeminfo file https://drive.google.com/file/d/1VtOeGQ9GnKvcSVgraPP6-go6HCRbpyBB/view?usp=drivesdk. It is a zip file, extract it to find an img file. Reboot to TWRP and select Install Image and install the file to oeminfo partition.
2. Perform a complete factory reset in TWRP.
3. Download the latest Nougat (3 files package) for FRD-L09C10 through Firmware Finder. Flash it using HuRupdater https://forum.xda-developers.com/ho...l-flash-official-firmware-recovery-t3769279/.
4. After the flash is complete, reboot the device, unlock the bootloader again and flash TWRP.
5. Download the latest Oreo build for FRD-L09C10 through Firmware Finder. Using HuRupdater flash the three Oreo firmware files. Don't perform a factory reset this time.
6. Reboot your device. You're now on Oreo.

Doesn't work for me. Always results in a bootloop with "Your device is unlocked..." etc.
Same with RedLotus too. I don't know if it's the firmware you linked or the recoveries, but ehh... nah, probably gonna go back to where I was before.

I tried out some of the EMUI 8 TWRP's that I could find but none works for the Honor 8 yet.
Would be grateful for a working one too.

Just to be clear, since I prefer not to f this up...this will pretty much let me rebrand from FRD-L04 without the need for a computer correct? Also these step you've laid out don't require any of the steps posted in the OP?

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
Cheers

Piece.

Hello,
I reinstalled the custom rom that I found on the net: C432B414 with Hurupdater.
It works.
However, the bootloader is still unlocked ... however, I would like to return to the factory configuration with the bootloader locked.

I have the stock recovery install :
https://www.cjoint.com/c/JItg7SqQmdB

For dual SIM only!
1. Unlock bootloader , (get unlock code here )
2. Install TWRP 3.0.2.0 (the p9 lite section is full of instructions on how to do it)
3. Download VNS-L31C432B370 fullOTA-MF-PV firmware (2 ZIP files), link:
https://cloud.mail.ru/public/D4kV/xcpuDX7Eu/
and copy downloaded files to the SD Card
4.reboot to TWRP, tap Install, Select storage Micro SDCard
5.Flash update с432b370.zip
6. go back without reboot (!!!), flash the additionnal package update_data_full_VNS-L31_hw_eu.zip
7. In TWRP's main menu select Reboot system.
Note: read the instructions carefully, check unfamiliar terminology by google or xda.
After successfully installing EMUI 5, you can upgrade to a higher build number via the dload method and Service ROM
B416
(Instructions can be found in ReleaseDoc folder).
Good luck!
P.S.:keep in mind that all firmwares that end with even numbers are for dual SIM (odd numbers are for single SIM).
