Try to do it over with AndroidBestieRE's rom link and see it if works then. After installing the images you may need to unlock the bootloader again (in case it's locked) try to install TWRP make sure you are using the right one for your EMUI, hopefully then you can enter TWRP. If you can you need to make a Data wipe everything on your phone will be deleted.
[Mate 8 General] hearts king101:
The problem i think is not with update, the problem is with flashing , everytime FAILED

no flashing command is accepted at all and that's what is driving me crazy :crying:
[Mate 8 General] GerManiac:
Just try it with the B172 ROM, you got nothing to lose
[Mate 8 General] hearts king101:
i'm downloading...

can i install it by dload mode ?? or will fail as its not compatible and i wonder what's the latest release after l29c185b160?
[Mate 8 General] danielg90:
I have final question, i reboot in twrp, go to backup, select all,but error "unable to mount storage" and "failed to mount 'data'". why?
[Mate 8 General] GerManiac:
Use the unbrick method explained in the OP. Extract the images and so on...
[Mate 8 General] GerManiac:
Did you format data in TWRP? It's an important step and necessary.
[Mate 8 General] DarkSilentSC:
I can see that this file worked for unbricking the device using italian knife, but did you get to update firmware to B321??

If so I need to know what app file you put on dload folder.
[Mate 8 General] AndroidBestieRE:
I have actually two devices AL10 and L29. The AL10 I could update with dload the L29 it did not work. So....

I used the L09 B321 and extracted the images from the update.app and did the procedure as if my device was bricked with the italian knife tool. I thought I give it a shot and it worked. So far no issues and device is acting normal. :cyclops:
[Mate 8 General] danielg90:
No, how format data in TWRP?

Inviato dal mio HUAWEI NXT-AL10 utilizzando Tapatalk
[Mate 8 General] GerManiac:
Boot into TWRP go to <Wipe> and select <Format Data> (everything on your phone will be erased)
[Mate 8 General] DarkSilentSC:
I FINALLY GOT IT!!! Here are the steps (Very close to Twisted Mate 8's L29 Instructions)

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!
[Mate 8 General] tdamocles:
Now this makes sense to me.. Going to use these steps to go from nxt l29 to b321 update. Thanks. The other way was a little vague for my liking.
[Mate 8 General] GerManiac:
Excellent, posted a link in my second post to your post so others can profit from it, glad someone added finally the right steps for the L29. I have an AL10 and can only confirm steps for that device.
[Mate 8 General] tdamocles:
update extractor freezes in windows 10

When I go to extract cust.img and system.img the application freezes. Did it give me good files? Cust is 400mb and system is 2.33 gb.

---------- Post added at 08:29 PM ---------- Previous post was at 08:19 PM ----------

Do I need to unlock bootloader again somewhere in there?
[Mate 8 General] DarkSilentSC:
Did it freeze or did you look at the progress window carefully and there's a close button?

My phone's bootloader stayed unlocked. Otherwise I guess you'll have to re-unlock it
[Mate 8 General] tdamocles:
There is a close button but it is not clickable, I have to go into task manager to end the extractor task. both progress bars got to the end but I can't close it.

How big were your files?
[Mate 8 General] tdamocles:
I get to #12 and flash both but twrp won't let me in without a password. What to do next?

I hit cancel and try to format data but it cannot mount anything. It says failed to decrypt.
[Mate 8 General] DarkSilentSC:
flashing insecured version of boot should let you format data using TWRP. That part of instruction is identical to how to remove EMUI's default encryption.
[Mate 8 General] tdamocles:
I got it..I was using the first go around of twrp4.1. It must have been updated at one point and I didn't know it was different.
[Mate 8 General] fdorr:
I have a AL10 Mate8 in the process to install a custom ROM thru TWRP im stock now in boot logo ...YOUR DEVICE IS BOOTING NOW... and now i tried lots of thing to get the device back to life, i also try Knife tool with Unbrick method then tried fastboot flash system cust boot and recovery extracted from AL10 B321 and from L29 and same problem.

Any idea? i waste all day with this!

Im missing a step?
[Mate 8 General] DarkSilentSC:
Take the UPDATE.APP from B170 firmware zip file. Take that to Huawei Firmware Extractor, Extract BOOT, CUST, RECOVERY, and SYSTEM. Place these four files into 'unbrick' folder in Italian Knife program, and unbrick it. This method should take you back to B170 stock image. Once that's done, follow the given instruction again.
[Mate 8 General] fdorr:
This works.!!!! Now the iPhone works again. Any idea how to get google apps on vhinese rom or how to flash a custom and not get stuck on huawei logo?

Enviado desde mi Nexus 6P mediante Tapatalk
[Mate 8 General] DarkSilentSC:
Not sure what you mean by vhinese rom, but you can probably follow my steps mentioned in page 6 post 56 to get stock EMUI 4.1 first, then flash insecure_boot and TWRP for EMUI 4.1, format data, then flash custom ROM that you like. Right now I'm using Twisted Mate 8 and brought my phone to most google stock-looking UI.
[Mate 8 General] fdorr:
Any idea howto make step by step this item?

3. Add firmware .zip file (which contains META-INF folder and UPDATE.APP) and place it into internal storage

And flasheit with twrp no?
[Mate 8 General] DarkSilentSC:
Copy the stock B321 rom zip file into your phone, so you can flash this file via TWRP. That's all there is to it.

Surprisingly my method doesn't involve force flashing ROM using Huawei's stock recovery.
[Mate 8 General] fdorr:
Great... and witch twrp do you use on 170? I have 3.0.2 but when i boot into it askme for a pass to decrypt

Enviado desde mi Nexus 6P mediante Tapatalk
[Mate 8 General] DarkSilentSC:
You'll have to search the proper TWRP version for that firmware. I think it was 2.8.7.0. But you can skip the password, and then go for format data anyway to enable access to /data/. When you flash insecure_boot image before, formatting data is mandatory. This will reset your phone, so I suggest you format data first, reboot phone to system again, then copy the rom zip to your phone one more time.
[Mate 8 General] fdorr:
But do i have to flash insecure boot imagen before all the process? Because un the steps its number 12 (step)

Enviado desde mi Nexus 6P mediante Tapatalk
[Mate 8 General] DarkSilentSC:
Okay the whole reason of flashing B170 is to unbrick your phone. I really implied a lot on the initial statement before all the steps mentioned, but you need to have B170 firmware with insecure boot with TWRP with format data already done.

The steps laid out actually uses B321 stock rom. I used AL10 B321 to get it working, even though I have L29.
[Mate 8 General] fdorr:
Ok i flash insecure boot on 170 and im bricked again :(

[Mate 8 General] GerManiac:

hi can somobody help me with installing twrp on my AL10?? ITS ALWAYS SAYING FAILD REMOTE COMMAND NOT ALLOWED, I DONT KNOW WHAT IM DOING WRONG, MY MATE 8 IS UNLOCKED, ALL DRIVERS AND ETC IS INSTALLED WELL , I THINK))) THX
[Mate 8 General] nakul:
Hello Guys do y forget select usb debugs in setting/developer options ?
[Mate 8 General] tarekbashir:
I had the same problem. It's because of latest Google security patches. After a factory reset the frp lock gets turned on and you could not flash anything through fastboot. You can however lock or unlock boot loader. The only solution I found is to unlock frp through using dc unlocker. You buy 15 credits and you unlock frp (factory reset protection lock)
[Mate 8 General] F1r3h4wk:
you could fix the same problem I have is not to do help me :(
[Mate 8 General] Talal Tango:
BRICKED

Seems like im running into a totally bricked phone. I've successfully rooted my device, installed TWRP, booted a decrypted img and wiped data.

My L29 booted perfectly, installed SuperSu to grant root access and here is where all the fun began. I idiotically made SuperSu to install the library automatically which led to a bootloop. I Can't access TWRP anymore, I'm also unable to access Huawei Recovery (some weird useless Huawei eRecovery appeared) and fastboot doesnt seem to accept commands when it comes to flashing.

1- I downloaded original Firmware and extracted update.app with HuaweiExtractor.

2- copied system,cust,recovery and boot images to Unbrick folder in Rayglobe Knife

3- Did the unbrick method but it seems that my fastboot is corrupted . It says FAILED (remote: Command not allowed) whenever I try to flash anything.

Now I'm clueless where to go from here. You can look at the attached fastboot and rayglobe pics below
[Mate 8 General] Pfeffernuss:
That's the very recovery I used to be able to upgrade from B180 to B3xx (restore a stock firmware first, over Wifi), so it's not useless at all.
[Mate 8 General] Talal Tango:
Unfortunately I've tried to restore stock firmware over Wifi several times but it always failed. Fortunately, using dload method via external SD card worked after almost 13 times of trying. Phone is up and running and I'm a happy man again :D
[Mate 8 General] Pfeffernuss:
Wow that was quite an ordeal! Luckily, all's well that ends well! :good:
[Mate 8 General] Talal Tango:
Hmmm .. seems like not all my problems vanished. My phone's bootloader is locked again and whenever i try to unlock it using adb this is what happens:

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock 331xxxxxxxxxxxxxx

...

FAILED (remote: Command not allowed)

finished. total time: 0.016s

Any ideas on how to get rid of this annoying stuff?

SOLVED: My bad, didn't turn USB debugging and oem unlock on
[Mate 8 General] Astra1:
I can confirm this method worked for me. I used this method to upgrade to B320 when everything else failed.
[Mate 8 General] darkthugs:
hello its my first huawei device so i find a little difficult to deal with it,i am able to flash the b330 complete and it will pop up that it will restart the device but it wont boot complete ,it will show the huawei logo and then dark screen,it is bricked ,i am able to flash it with the volume up and volume down +power button .any idea??:(
[Mate 8 General] GerManiac:
A little bit more information would be nice.

What version were you on? Rooted? Bootloader locked... Things like that...
[Mate 8 General] cocoapapi:
OK, I may have bricked my phone for good. I got confused in the steps. Anyway, I was able to get my L29 from b180 to b321 using http://xdaforums.com/mate-8/general/unbrick-updating-to-b321-t3375934

then i was trying to get it to TWRP and it seemed like it wouldn't work. I can only get the eRecovery of Huawei's and when i push the down button and plug in the USB, it looks like it's in fastboot mode but the Rayglobe knife program doesn't see any devices. When I do the initial setup on the phone, it won't let me get to the main screen on the phone, it loops the setup asking the same thing over and over [country, language, wifi, etc.]. Please help with ideas or let me digest the fact i have a $600 paperweight :-/

***UPDATE*** I used DC-Unlocker to remove the FRP lock (Paid $15 bucks) but it's free again
[Mate 8 General] bluheart:
Use the Huawei sync pc software to restore your mate
[Mate 8 General] DarkSilentSC:
Wondering if you can tell me which step you got stuck on based on my provided instruction. If you don't flash all the required images and zips, you will not get a successful boot. If you're sure you followed the procedures, you'll need to have a bit of patience. I think it took me 5-10min to fully boot.
[Mate 8 General] darkthugs:
thanks for the answer ,unfortunately i dont know,i bought it bricked hoping to restore it,i was able to flash the B330 firmware by the volume up and volume down +power button,will update to 100% but after that,it will restart and then nothing will happen
[Mate 8 General] DavidTaborda:
THANK YOU!!!! I've unbricked my Mate 8 (NXT-L29 4GB RAM). All my data is ok, too!
[Mate 8 General] darkthugs:
hello my phone was also bricked and i was able to flash one rom to the 100% by forcig the flash with the volume up+volume down+power

then when i tried to enter again to the fastboot it popped FRP Lock.i see you purchased credits on that dongle,if i purchase the credits and use the dongle

the phone will boot up completely or only erase the text??

---------- Post added at 10:50 PM ---------- Previous post was at 10:45 PM ----------

thanks for the reply i really appreciate it,my device its one 109,and as i said i was able to flash the b330 rom by forcing the update with the sd card (combo key procedure),unfortunately it will complete to 100% and then proceeed to restart but wont completely boot up

after that update when i enter the fastboot and rescue mode now will appear some FRP lock wich wasnt there before,i saw one member here purchased one service ?if i purchase the phone will boot up completely or only will remove the FRP text??

or any other idea??and thanks a lot i really appreciate it.
[Mate 8 General] darkthugs:
i downloaded that app Dc unlocker,when reading my phone it popped the next

Serial NR. : AXS0216318001890

Firmware : NXT-C900B321

FB LockState: LOCKED

USER LockState: LOCKED

locked,also when trying to flash anything with ray tool to unbrick it will always pop fail with every file(cust,boot,recovery and system),should i pay for the unlock to be finally able to restore it??
[Mate 8 General] GerManiac:
With a locked bootloader, all you can do is flash a stock ROM!!

Find yourself a stock ROM made for your device and flash it.

You can also try to use HiSuite from Huawei to restore your device.

Or you pay to unlock. Keep the unlock code safe for later use. You'll probably need it at some time again
[Mate 8 General] DarkSilentSC:
You mentioned forcing the update with the sd card. Did you mean using the Huawei Recovery tool? If your device is L29, my instruction does not cover such instruction. Since your device won't fully boot up anymore, I suggest that you go back to B170/B180 and start from beginning. Using my instructions.

Hey folks,

it seems that today I (soft) bricked my phone.

I've been playing around w/ some ROMs and recoveries & suddenly my phone got stuck at the »your phone cannot be trusted« screen.

My biggest problem is, that my phone won't boot into recovery.

I followed the steps in the OP and flashed the latest stock firmware (NXTL29C432B320FULL) through the Italian knife.

Now my phone went a little bit further, but got stuck at the Huawei logo ... and it won't boot into recovery as well.

Has anyone else any other idea what I could do, to bring my phone back to live?!
[Mate 8 General] bluheart:
Unzip your firmware in a folder on ext-sd card and name it dload then reboot into recovery. Everything will be fine
[Mate 8 General] d0pecr4wler:
Okay, got my phone back from the living dead via Wipe Data / Factory Reset w/ the Huawei eRecovery.

Now I'm back at stock, but I still have my bootloader unlocked.

Problem is, I flashed TWRP via fastboot, but my phone doesn't go into TWRP if I hit the buttons,

it always goes back to the Huawei eRecovery.

Anything I can do to enter TWRP again?!
[Mate 8 General] nakul:
your phone errors with unlock boot loader

try relocks again
[Mate 8 General] d0pecr4wler:
Tried to relock it via fastboot, but w/o success.

I always get the error »command not allowed«.

Developer options, USB debugging options and Enable OEM unlock options are enabled.

Diableing one or all of them doesn't change anything.

Any further ideas how to lock the bootloader?!
[Mate 8 General] bluheart:
Do dload and you should be fine
[Mate 8 General] nakul:
try with dload agains
[Mate 8 General] d0pecr4wler:
I already did that.

If I try it w/ the button method, my phone always gets stuck at the »Your device has been unlocked...« screen.

If I try it w/ the dialer code method, my phone restarts and than gets stuck at the same screen.

Just tried it again, looked at the said screen for 10 minutes or more ... but nothing happens.
[Mate 8 General] bluheart:
Ok.

Once you do dload, reboot into Huawei recovery and wipe everything then reboot

So unless there is something I'm doing wrong I'll just start again as I really didn't follow any guide as I've had so many issues.

Soo I'll do a brick update to b170 then someone said I've got to use trwp to install the update from firmware.zip do we have to update via twrp or can we do it via other methods.

Also I don't have the firmware.zip file why not just use the upgrade.app

OEM - unlock option missing - AL10

Hi,

Thank you so much for this thread and these steps.

I have NXT-AL10 - bootloader - locked - currently I am on B577 Android Nougat.

I want to root my Huawei Mate 8 and have B577

For unlocking the bootloader.

I don't have the OEM unlock option in the developer options.

Is it important to get that option? or can I just go through the 5 steps you have mentioned to get the bootloader unlocked?

Should I downgrade to B386 - unlock the bootloader - flash TWRP 4.1 and get root?

And then to upgrade to Android Nougat from B386. I have to flash the Nougat zip files from the other thread and flash TWRP for 5.0? and then reboot. Is this correct?

Please advise.

Thanks,

Sam

[Mate 8 General] Samavb:
Can you answer these questions below to help you better?

What was the firmware on your phone before your phone starting giving trouble?

What I mean is did you debrand your phone to L29 and then it got bricked? Or is it still in AL10? Very important question, so pls answer carefully

Did you try dload using this rollback package?

Do you have the rollback package ? This is very important file. See the link below.

http://consumer.huawei.com/sg/support/products/downloads/detail/mate-8-sg.htm?id=91647

Only this file can succeed dload because you have nrd test keys

Remember this is rollback package for L29

So if you debranded your phone to L29 from AL10 use this file

This is straight from Huawei.

Just put the update.app in dload folder on your external sdcard

You have to create this folder manually if you don't have it already.

Then do the three finger rule to dload.

This time it should work.

Don't forget to answer questions above

Hope this rollback package helps, if not we will think about plan B or Plan C.

Don't forget to hit :good::good::good::good:
