[GUIDE Step-byStep]RETURN2STOCK/UNBRICK/UNLOCK/ROOT] e.g. STUCK AFTER UPDATE

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!

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

Help. have anybody succeed downgrading from emui5 to 4.1?

i mean .. i tried everything
but.. still i stock on this ugly thing
can anybody help me?
im a NXT-DL00
kinda desperate

It's not as complicated as you might fear, stick with this and we'll get you back to 4.1
You have to be using EMUI 5's stock recovery for this to work, if you don't have it anymore use the Huawei update extractor to pull it and then install it via fastboot.
Then place the update.app file from the 4.1 firmware you want to roll back to into a folder called dload in your internal storage's root directory.
Turn your device off and hold VOL+, VOL- and power at the same time, it should enter dload mode and automatically start updating. when it is done you should be back to 4.1
You'll need to re-unlock your bootloader and reinstall TWRP for 4.1 but that should be it
any questions?

Ok, so you should already have it, unless you installed some form of TWRP since updating to EMUI 5.
If you don't have the stock recovery anymore:
extract the EMUI5 rom zip that you flashed to update to your desktop
download this tool on to your computer
http://forum.xda-developers.com/showthread.php?t=2433454
run it and hit the "..." button, this will open a new window, find the update.app file that you just extracted and select ok.
This will bring up a list of files one will be called recovery, right click it and click extract.
Then in fastboot mode:
Code:
fastboot flash recovery recovery.img
let it run and you should have the stock recovery back again

That's fine, try a different update. Mine worked on B321

please I need to remove twrp recovery

I need to remove twrp recovery and install stock recovery image
How I can do this gra ul10

Hello! You would be willing to change the ROM?

Uh oh. This reminds me 1 year ago when I had your same problem . The process is simple:
1. Get the UPDATE.APP file wich is no more than all the stuff for the P8 wich includes the recovery. You should find it on emui.huawei.com
2. To see what's in there you need a tool called "Huawei Update Extractor". Just look for it
3. You do the same process for installing TWRP but with the image file "recovery.img"
And you're done
PS. Do a full backup with TWRP just to be sure. To restore it just reflash TWRP and use the restore function

You could flash the original recovery via fastboot if you have a backup of it as raw image.
Or well what @Rome7643 mentioned works also. I submitted a profile for the gra-l09 for the update extractor.
command is like "fastboot flash recovery <path/to/recovery.img>"
There is recovery and recovery2. One of them comes up when usb is connected one when it is not connected when triggering the recovery boot.

Download the UPDATE.APP from a recent stock rom, use the Huawei Update Extractor, then flash the recovery/recovery2 partition with the recovery.img/recovery2.img.
Like "fastboot flash recovery recovery.img" in fastboot mode.
This will only override recovery.
Note that recovery and recovery2 is the same but one triggers only when the usb cable is connected.

I seem to be having the same problem. In the update.app I dont see the recovery.img file. Instead there are 3 files
recovery_ramdis
recovery_vendor
recovery_vbmeta
please advise.

Please, next time you should be more careful when downloading the file UPDATE.APP or update.zip ! I guess you downloaded one from Huawei P9, but for sure it's not for Huawei P8 !
After you unpack update.app there should be RECOVERY.img and RECOVERY2.img along with others partitions images.
Good luck !

I am sorry if I posted in the thread for the wrong phone. I have a mate 9.

[Guide] (2017.12.07update) How to root ur Mate9 oreo (emui 8.0)

First of all, sorry for my awesome English.i am praticing my writing
if u understand Chinese,congratulations!these is the Chinese version:
Notice:
A. Warning! Flash phone might get it bricked. I am not responsible for it.
B. Phone is already Oreo firmware.
C. i cant guarantee these is no needless steps , but at least , i execute the steps from a to m, and i succeed to root my mate9 oreo {MHA-AL00 8.0.0.334(C00)}
-----------------------2017.12.07 update---------------------------
sorry for so many needless steps of the old method.
root mate9 emui8 now only need 2 steps (so please neglect the old method).
new method:
1. reboot to fastboot mode . and fastboot flash recovery_ramdisk this
2. reboot to recovery mode. flash supersu 2.82 sr5 mod. (download link)
done!
ps: i have compared the "supersu 2.82 sr5 mod" to official supersu 2.82 sr5
the only different is:
the 683th line of file: "/META-INF/com/google/android/update-binary"
official package is : TRY="boot_a BOOT_A $TRY"
and the mod package is: TRY="ramdisk_a RAMDISK_A $TRY"
so the the mod package can be trusted i think.
that's all !
as the Chinese popular saying goes： 无图无真相！( no pictures! no truths ! )
but i dont know how to upload my picture, imgur?tumblr? anybody teach me?
HOPE THE ABOVE IS CLEAR.
GOOD LUCK
----------------------------------------------------------------
old method ( too many needless steps, please read the new method!):
Prepare:
1. FunkyHuawei Mate 10 Root/Rebranding tool (find lastest release here)

4、update_data_public.zip & update_all_hw.zip for the corresponding version you need (mine is MHA-AL00 8.0.0.334(C00), you can find wat u need at here)
5、supersu 2.82 SR5 (donwload link ,we only need the superuser.apk in /common.)
steps:
a. Unlock bootloader (backup all the data you need before this step)
b. Decompress the HWOTA8 Package on ur PC.
c. Copy the TWRP 3.1.1-0 to this folder (created by Decompression ),and rename this recovery img file (TWRP 3.1.1-0) to "TWRP8_3.0.3.img"
d. Connect ur mate9 to PC by USB cable and Use Vol-Dn +Power to boot into fastboot mode.
e. Use "Replace_Recovery.bat" in the folder (created by Decompression ) to flash TWRP recovery
f. Disconnect USB cable, use Vol-Up + Power to boot into TWRP
g. Format Data in TWRP, and connect USB cable again.
h. Reboot into fastboot mode .
i. Decompress FunkyHuawei Mate 10 Root/Rebranding tool Package on ur PC.
j. Run the "FHMate10Tool.exe" and choose Option 1 to root. and it will reboot later
k. Phone reboot ---> appare the warming interface ( it said:your device has been unlocked and cant trusted blablalba..... ) ---> appare the huawei welcoming interface -----> suddenly, phone reboot. notice!: please keep USB cable disconnecting from ur Phone. and after phone reboot suddenly , keep holding the Power + Vol up as fast as u can to reboot to recovery mode. (ps: why do we hold the keys as fast as u can? because it will prevent ur rebooting phone enter the huawei welcoming interface again. if the huawei welcoming interface appearing we cant execute the step l following)
l. flash the update_data_public.zip & update_all_hw.zip in TWRP. and reboot to system .
m. if supersu is not installed, please install supersu 2.82 SR5 manually.

no version for Oreo until now as i know

I want to restore my Mate 9 to stock recovery and have used Huawei Update Extractor to extract the Oreo 1.9GB Update.app.
Which of the following files should I use to fastboot flash the stock recovery?
RECOVERY_RAMDIS.img 32MB
RECOVERY_VBMETA.img 6,93kB
RECOVERY_VENDOR.img 16MB

/recovery has a new name "recovery_ramdisk" in mate9 oreo
if you want to flash stock recovery , you should execute " fastboot flash recovery_ramdisk xxxxxxxxxxxxx.img" in fastboot mode.
"RECOVERY_RAMDIS" may be refer to "recovery_ramdisk", so try to execute " fastboot flash recovery_ramdisk RECOVERY_RAMDIS.img" in fastboot mode.
i'm not sure.
gook luck!

At first I saw two files no have "update_data_public.zip" file
I decided to take action. While there are only two files. I think there is nothing wrong
But I made a mistake. It is not available.I just saw it later. "update_data_public.zip" file
The symptoms are now.
1.Use a bootloader
2.Use twrp Can not access. Hang on the logos page.
3.I do not have a boot "Your device is booting now.."
And I tried flash with fastboot but It's cannot load system.img
I use the UPDATE.APP file from this link. 3 file flash on fastboot [1.recovery.img 2.boot.img 3.system.img]

I'm not sure It is a system.img issue . Or because the firmware does not match.

Do I use 3 files correctly? I find the best.
