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 .

Yes it is red message verification failed message.
I'll change AL10 to L29C432 when I can do that
The bigest problem is that I stuck on androit 7.0 emui 5.0.
So maybe you help me unlock bl (I have unlock code) and flash TWPR....

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.

You have to debrand your phone...
That presume: unlock bootloader + twrp + root + (prepare in dload folder a C432 - B160/B161 firmware) + flash oeminfo C432 + repair firmware with dload folder.
It is a lot to do and somethings may goes wrong resultin in bricking your phone...
If you assume the risks, after that you have a C432 - B160/B161 phone which can be updated to B370/B371 via Firmware Finder.

What you have to do i already said but you have to read arround here to do followings...
1. From anywhere you are (B336, B329, B170-160-130) you have to prepared in dload folder a B160/B161 stock firmware (B160 for Dual Sim, B161 for Single Sim).
2. Flash oeminfo/custom.bin (for SS phone or DS phone ) for your phone localisation: C150, C185, C432.
3. After that firmware become corrupted and need to be repaired from dload folder via 3 keys pressed / dialer code / emui error message.
4. Once you have a functional B160/B161 firmware install Firmware Finder (+proxy addon) and check <Use new firmware> and <Use system updater>.
5. Reconfigure WI-Fi connection from indications in Firmware Finder Proxy.
6. Search for B370/B371 firmware (B370 for DS, B371 for SS) of 1,94 Gb size for your phone localisation and send it to updater.
7. From there it is downloaded, verified and reboot to emui updater wich make his work and bring you B370/B371 firmware.
PS: - for flashing oeminfo/custom.bin i recomand this tool which make that work just fine.
https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
- if you have a flash-able zip of oeminfo/custom.bin i recommend flashing with twrp.

Bricked after changing to wrong(?) oeminfo in L21

Hello guys...
I'm so stupid that i was even trying to do something with my phone. I got P9lite from my local carrer (PLAY) (L21C900B160) and i was trying to debrand it. Bootloader is unlocked and i flash TWRP for install new oeminfo (i think i just downloaded wrong one). After that i wanted to reflash my soft via dload (L21C900B160) to same version. Then i realize that i can't do it coz "its not valid version, try correct version" (i was using same dload software before). After that i was trying to normal boot my phone but i have "Type password to decrypt storage" and i'm writing correct password and i see "DECRYPTION UNSUCCESSFUL. You entered the correct password but the data on your phone is corrupt. To resume Using your phone you must perform a factory reset [...]" and i'm doing it. Factory resed done "Successful" and i reebot my phone to set it up but i see always "Type password to decrypt storage". I can't use fastboot commands in fastboot/bootloader mode (even try to find out that my phone is still bl unlocked), and i cant do anything with it. I don't know what to do with this. Please help me guys
EDIT:
1. What can i do with it?
2. It was big mistake to flash oeminfo (c432) to my c900?
3 . Can anybody tell me what's wrong with this oeminfo zip? Added to download for you.

If you used a C432 OEMInfo you must download and install a firmware that is C432 and Marshmallow.. Say B120/B160 and try to flash it through 3 buttons method.. You should get a phone working

I was trying it but installation failed

Your attach oeminfo is for VNS-L21 Dual Sim, and is fine.
That problem with error corrupted firmware is normal after you flash oeminfo...
Something else is going wrong...
You are sure that you put in dload folder on microsdcard update.app from VNS-L21C432B130 stock firmware?

After flash oeminfo, power off phone and started with 3 keys combination.

Can you send me link for 160 update.app? I'm in job and it's hard to search anything on backup phone. I will download this update file and try to repair phone on break from job.
EDIT: I MEAN 130 UPDATE.APP FILE, MY BAD

New method for rollback Mate 9 (no root,no unlock)
You can use hisuite update mode for rollback from andriod 8.0 to 7.0

Just to clarify 2: You need to rebrand to AL00C00. C636 won't work, it fails at 32%.
Use this to get AL00C00 dload and oeminfo https://forum.xda-developers.com/mate-9/how-to/guide-rebrand-chinese-al00-mate9-to-t3554656

Are you investigating rollback ROMs? Huawei posted them to HiCloud and they are available in FF. Do they work?
They can be installed via hwota only, cause they have online_update tag (no dload option).

They are not approved (yet anyway) so it's HWOTA only.
They should work. The "rollback" FH uses is just the B194 OTA, but it won't flash if you modified /system etc.
I'm trying to get a hold of mankindtw to create a patched recovery for Oreo.

Follow op.
1. Unlock bootloader and flash TWRP for Oreo
2. Rebrand to AL00C00. Download dload b115 from here: https://mega.nz/#!88RmjJjA!gGmuc0gL-_sPHOQ0VAXZgTJ3lXmlRRmBqXIYNEyw9XY extract and copy dload folder to external sd.
I used al00 oeminfo from hwota (https://drive.google.com/open?id=0B2D9GdWntw69RXRTcHBKbV9SMWM) then flashed it manually in TWRP using terminal.
Copy MHA-AL00C00.bin to root of external sdcard.
cp /external_sd/MHA-AL00C00.bin /tmp/oeminfo.bin
dd if=/tmp/oeminfo.bin of=/dev/block/sdd5 bs=1048576
3. Now reboot to eRecovery and let it download firmware which will fail. (Not sure if this is really necessary)
4. Reboot using Vol up+vol down+power, wait for install to finish
5. Use this https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108 to rebrand back to your firmware.

Hi,
1) wipe Dalvik & cache, flash stock recovery of b370, and then do like you wanna update to b380 using firmware finder, (use the big file)
or
2) rollback to MM : flash oeminfo for your location (recommended) , flash Rollback Package via dload , and then flash stock B160 via dload.
or
3) remove root from SuperSu app, then use Rocatex uninstaller
