How to unbrick or get back stock on your Huawei Mate 8. There are many reasons why you would want to do that.
In my case my device (AL10) was stuck at "your device cannot be trusted" after updating from B180 to B321.
First I got to thank acer73 for his software. ajsmsg78 and Kris Chen for their links to the right ROMs.
Also thanks to DarkSilentSC for his help, especially with the L29, great support.
He has a L29, which I don't have, so I'm glad he provides help with that device.
This worked for me on my AL10 to get it back on track, should work on other models too. Just have to find the right ROMSs as according to your model. However, I am not responsible if this does not work for you or if it bricks your phone even more.
And remember: don't forget turning on usb debugging whenever you can!
Unbrick (return to Stock)
1. Find yourself a stock ROM.zip according to your model and extract from the zip the update.app (I used one from a B172 (AL10) Stock ROM, I was running a B180 custom ROM, it worked.)
2. Download the Huawei Update Extractor http://forum.xda-developers.com/showthread.php?t=2433454
3. Extract boot.img, recovery.img, system.img and cust.img with the HuaweiUpateExtractor from the Update.App you find in the ROM to somewhere where you can find them easily
4. Head over to http://forum.xda-developers.com/mate-8/development/rayglobe-italian-knife-t3295526 (You can also do it with fastboot commands, but Acer73's tool makes it easier)
5. get yourself the Italian Knife (btw you probably have to turn off your anti-virus program), extract it in a directory on your PC and start Rayglobe_knife.exe
6. Put the images you have extracted into the folder Unbrick (same directory where you extracted Rayglobe Knife in). The folder was created after you started Rayglobe_Knife.exe
7. Boot your phone into bootloader.
8. In the Rayglobe Knife tool choose Unbrick and choose the option where it says you have placed all the images in the unbrick folder.
9. let the magic work. The phone will restart and it will probably take 15 minutes, make sure its charged enough.
After all that I quickly updated to the latest Stock ROM version, in my case B321, which you need to do if you want to flash later a custom B321. See second post if you want to do that as well or continue with unlocking the bootloader.
Now lets get the bootloader unlocked (for some reason mine was still unlocked)
1. Get Minimal ADB https://www.androidfilehost.com/?fid=24521665358595410
2. Hopefully you still have your unlock code (cause you need it otherwise it won't work)
3. Put your phone in Bootloader Mode (Press & hold power and volume down)
4. Extract Minimal ADB zip and run command.bat
5. Type <fastboot oem unlock xxxxxxxxxxxxx> (where xxxx is your bootloader unlock code)
6. Done
Now lets get twrp set up
1. For that we need minimal ADB again
2. Headover to http://forum.xda-developers.com/mate-8/development/recovery-twrp-huawei-mate-8-t3298567
3. Download TWRP according to your EMUI (For B321 it's EMUI 4.1)
4. Place the image in the directory of the Minimal ADB
5. Rename it to just twrp.img (not necessary but simplifies things)
6. Put your phone in Bootloader Mode (Press & hold power and volume down)
7. Run command.bat
8. Type <fastboot flash recovery twrp.img>
9. Then type fastboot reboot
10. Now you can hold volume up and power until your phone boots into TWRP
11. You need to format data (you'll lose everything on your phone)
12. Done
Remember: don't forget turning on usb debugging whenever you can!
!!!FOR L29 scroll down to DarkSilentSC's instructions!!!
After unbricking I quickly updated my AL10 to the latest version, in this case B321. Should work with all B3xx
1. Head over to Kris Chen's thread (this I used for the AL10)
http://forum.xda-developers.com/mate-8/development/rom-verison-t3324164
Or ajsmsg78's (also AL10 and L09)
http://forum.xda-developers.com/showpost.php?p=66776194&postcount=58 to get the Stock B321
2. Download the ROM and after downloading the zip file, extract update.app from it. Copy the UPDATE.APP to the internal memory of your HM8 in a folder called - dload (you may have to create it). Then press [volume+]+
[volume-]+[power] together to force the update.
3. Voila B321
-----------
!!![For the L29 you should try DarkSilentSC's instructions, which you find below or in post #54 on page 6 http://forum.xda-developers.com/mate-8/general/unbrick-updating-to-b321-t3375934/page6 don't forget to hit thanks!!!
1. Start from stock B170 firmware with TWRP ready
2. Extract BOOT, CUST, RECOVERY, SYSTEM from B321 UPDATE.APP
3. Add firmware .zip file (which contains META-INF folder and UPDATE.APP) and place it into internal storage
4. Make sure internal storage data is fully backed up
5. Delete All Accounts in Settings
6. Go to Recovery, Wipe Cache, Delvik Cache, Data, System
7. Flash that .zip file! (Getting errors is okay at this time) [This is what I didn't do before!]
8. Boot straight to bootloader
9. fastboot flash boot, cust, and system
10. let it boot. Let it proceed with encryption process in chinese and fully boot into EMUI
11. NOW I'M AT EMUI 4.1!
12. Reboot to fastboot and fastboot flash insecure_boot and flash TWRP
13. Reboot to recovery (TWRP) and then flash whatever rom you want to place in!
14. Enjoying it!
Great, was looking for details instructions like that, was stuck at cannot be trusted screen

Which update.app did you use? Maybe your download is corrupt?
BTW I debranded mine too with Acer's to international.

But you first used different ROM images to unbrick and then tried to update to B321.
really sounds as if your file is corrupted. Would try to download it again

ok i will try tommorow......thanks for help by theway the phone booted but if i flash recovery for root no boot.... very strange....sometimes aloud to flash from boot some times no ohhhhhhh(((
Or something no correct with huawei extractor..... Can you provide extracted files?
Thanks in advance.
So I unbricked with B170 and then tried force flashing B321. My first attempt at flashing B321 ended up getting stuck at 5%. Tried flashing again and it said it was incompatible with the current firmware version of my phone. Any ideas on what I should do next?
Edit: Nevermind. I mistakenly copied the UPDATE.APP from B170 to the dload folder instead of the one from B321. lol
Now on B321. Thanks!

Don't know which ROM you used to unbrick.
But seems that you used an B321 if that worked for you and you have no problems then that is great.
Could mean that wet can unbrick straight with the most current ROM available. If someone else could confirm?

sorry, is possible flash with knife if bootloader is locked? my bootloader is locked
hello, my phone is still stuck.. i tried other cust/system/recovery/boot from other update.app, but its still stuck at: your device has been unlocked... im on l29
Have NXT-L29, downloaded stock L09 file from posted link, placed UPDATE.APP into 'dload' folder which I created, but still hanging at 5%. What to do?? Exactly where do I create this 'dload' folder? Just at 'Internal Storage'?

Bootloader has to be unlocked. You can unlock best with DC unlocker, it's fast and only costs around 5 dollars.
Unless you already have your unlock code then you can unlock following instructions see my first post

You should unlock your bootloader and flash ROM via fastboot. That will upgrade your phone to 6.0. Would you like directions on how to do that?

For me, this ROM has reported problems. It could be the reason for the failed flash.
I do not think of being able to access the internal memory (with USB) to replace the ROM.
I thought that I can:
1) to performed hardreset (vol+-power, EMUI menu)
2) To put another rom on an external memory
3) Do unbrick again
What you think?
but I check now, Your rom is perfect.
I don't know what to do anymore

Guys help us about the camera. I am in the same exact situation. @BadWolfYe and your product_V3 doesnt fix the camera for me, VNS-L21.
And for the recovery - http://forum.xda-developers.com/hua...ecovery-twrp-3-0-2-android-nougat-03-t3511937 - use adb flash it.
dancress said:
You'll have to go the hard route. You'll find all the required files in the ROM section.
Download any Nougat.zip (329 worked for me, 336 did not). Unzip. You'll get the update.app.
Download the second file with all the missing apps. Do not unzip. Maybe rename to something shorter like data.zip.
Download Revolution Recovery for Nougat. Unzip. You get the recovery.img. RENAME to something like revolution.img.
Open update.app in Huawei Update Extracor. Extract recovery.img, boot.img and system.img to wherever your fastboot.exe is. It's practical to put it all in one directory so you don't have to type long paths.
Now, careful...
Go into Fastboot. If Vol- + Power doesn't work, let it boot into eRecovery, press Vol- and tap Reboot. There you are.
Open a command window in the dir with fastboot.exe and the .img files (right click, Open Command Window)
fastboot flash boot boot.img
.... OK
fastboot flash system system.img
.... sparse 1/5 or something, this takes a bit of time.
fastboot flash revolution.img
.... OK
Now DO NOT REBOOT into System. Hold Vol+ + Power while still in Fastboot. It'll boot into Revolution eventually. Tap Advanced, ADB Sideload. Swipe.
Back in your command window, type:
adb sideload second_file.zip
... working... this'll take a bit. There might be an error message like 'could not mount /data'. Doesn't matter at this point.
When done, type
fastboot flash recovery recovery.img (this is the stock recovery you extracted from update.app)
... OK
Reboot to recovery from Revolution.
Do factory reset. Note: If you don't do this last step, there will be a bootloop.
Reboot. The system should now boot up normally. At least it did for me... good luck.

I did this too. Only way to fix it is to downgrade to MM (instructions are in the N install thread). I then unlocked the bootloader, booted to fastboot, flashed Meticulus recovery. Once you're here, the important thing is to flash the update.zip and appropriate .Zip file for your device. Took me a while to find it but Meticulus has a post in Spanish with all of them for each type of P9 lite - there's one for the VNS-L23 there. Flash the update.zip and then device zip (in that order) and reboot. It'll work.
This phone is harder to flash Roms than others I've had in the past... It's important to do things in the right order.

First thing when you want to do something (TWRP, root, custom ROM etc.) with your phone is: UNLOCK BOOTLOADER!
Without unlocked bootloader is not hard to do, you not even try, because it is impossible...

For unlock bootloader you only need you phone to boot into bootloader...

You have to saved anywhere first time you have'it!
That is the first rule!
Once you debranded your phone that Device ID is change,
so even your phone boot ok and you obtain a Device ID is not the same
with the one saved in the Huawei databases...
So, procedure to obtain the bootloader unlock code is ended in error...
Guys I'm really lost trying to upgrade to Android 6 or even 7.
I know I must upgrade to at least EMUI 4.0
I know I am rooted.
I'm unsure if I have unlocked my boot loader.
How do I easily change Country Codes? Do I even need to do it?
I think if someone can assist with these early steps, then I can proceed alone to install new ROMs etc.
C636 is for South East / South Asian regions...
To check whether you've unlocked your bootloader or not, just boot into the fastboot mode... To do that, shut down your device completely then connect your device to your laptop / PC holding the volume down button. Once you enter into fastboot mode, there a Message will be displayed under the Android Logo. You can confirm whether your bootloader is locked or not.
If your only goal is to get Marshmallow, then you can search for firmware and then manually upgrade using the dload method.
First, you download the required firmware (gradually up to Marshmallow), then you extract the update.zip to get UPDATE.APP file (usually 2.3GB+). Then you copy the UPDATE.APP file into a folder named dload. You must then copy this dload folder to the root of Internal Memory and you can update your Android through Updater.

C636 is for South East / South Asian regions...
To check whether you've unlocked your bootloader or not, just boot into the fastboot mode... To do that, shut down your device completely then connect your device to your laptop / PC holding the volume down button. Once you enter into fastboot mode, there a Message will be displayed under the Android Logo. You can confirm whether your bootloader is locked or not.
If your only goal is to get Marshmallow, then you can search for firmware and then manually upgrade using the dload method.

try installing TWRP v. 3.1.1... That's the latest TWRP and compatible with Marshmallow...
Hello everyone.
I managed to brick my p9 lite (VNS-L31C432 dual sim) by flashing the rollback package over B161 (I know B160 is for DS, I just missed the correct update.app twice). The current status of my phone right now is:
- Phone won't boot, is stuck at "Phone is booting now"
- VolUP + VolDOWN + Power combination doesn't access to dload. If I have it connected via usb to my computer it kinda enter to dload but an usb plug symbol appears and does nothing
- Can unblock/rebock bootloader
- Can access to TWRP 3.0.2-0
- Can access to Fastboot and flash partitions, however when I do it TWRP lose the ability to mount them and they appear as 0MB partitions (I have to change fs to EXT2 then to EXT4 to make them work again).
So, from where should I start to try to recover my phone?

Hello,
unlock again the bootloader then use correct rollback package (or flash L31C432OEMinfo_bin dual sim file with TWRP) and DLOAD correct firmware this time...
If you are unsure just ask...
Cheers

Thanks, pal, but I already fixed it, doing a lot of trial-errors
If someone who had the same problems I had is reading this, what you really need to do is:
As Dadditz said, flash first your correct oem info, then unlock the bootloader
If you can't access dload, find the full-ota package for the exact same version of MM you previously had (before the brick, of course). Unzip the UPDATE.APP and then use UpdateExtractor to get BOOT, SYSTEM, RECOVERY, RECOVERY2 and CUST. Flash all of them via Fastboot.
If you try to boot and it gets into eRecovery, then it's a good sign. Put the UPDATE.APP from the previous step in the dload folder of your SD, use the dload method and let the install run. It will probably fail at the end, this seems to be normal.
You phone will boot and it will probably feel like it's working ok again, but I bet there are chances that a some stuff doesn't work or even appear at all (first time the fingerprint config didn't appeared to me, second time was the google account login). Turn off the phone, install the correct version of TWRP, wipe cache/dalvik, then do a factory reset (dunno if both are needed, I just did it this way and it worked ok).
Reboot you phone. Now it should really be working ok again.
If you little P9-Lite refuses to update to a newer version, use Firmware Finder to upgrade whatever version FullOTA-MF-PV you want to (in my case, I did to B370).
Enjoy
I'm still wondering why installing the wrong rollback package messes up with the recovery2 partition...
