Huawei Mate 8 in trouble

ok

good that you answered these questions.

You had L29 which you debranded to AL10 -> I was thinking reverse based on your previous post but it is clear now.

Your phone is AL10

try to put it in fastboot mode.

You have to press and hold down button & then connect it to your laptop

It will then go to fastboot mode.

Open hisuite and click on system recovery.

If it recognizes your device, then you will be able to get B386 on your device using Hisuite.

if this doesn't work

then you can go to this post

https://xdaforums.com/showpost.php?p=65544452&postcount=1 like it was mentioned in the first page of this thread.

You mentioned it is showing verification failed so you have to unlock your bootloader again.

even though it says your bootloader is unlocked , you still have to unlock it again .

once you unlock you can push the twrp 3.0.2. img file using adb commands inside srk tools

Since B386 dload didn't work for you, try other firmwares from this post and see if any of them work.

you can try to dload B321 or B368

please check the screenshots on how to enter command prompt in srk tools and also how to push adb commands.

for adb commands use srk tools

yes open srk tools type 000 in the place where it will ask you to type 1 or 2 or 3, in that same place type 000 and then you will be in command prompt

from there you can push the twrp image into your phone.

In srk tools - adb will always recognize your device, I can confidently tell you that.

you hav to put the twrp in the same folder as your srk tools and also name it as twrp.img

from twrp you can flash B180 or B321 stock firmware (this is one option)

you can give it a try.

if this also doesn't work then we will try something else.

but pls use proper files or it will give error.

hope this information was useful for you and hope you are able to resolve your issue.

hello everybody,

i have a huge problem with my Mate 8 (model NXT-L29), no matter what i tried i just cant get it to work again, i got the cellphone from my father in law, he did bootloader unlock code on it, and flasht it with fastboot supersu, but at first he did not tell me that he did all that stuff on the cellphone and second thing he did not tell me that i am not allowed to update it. couple days after he gave me the phone a new update came out so i installed the new emui and android update and booom, the phone did not work right anymore tryed to reset it and everything but it went worse and worse, now i am the point where my starting screen says "your device has failed verification and may not work properly." to learn more visit blablabla. (1) press power key to continue (when i press it nothing happens), (2) press volume up key up to 3 seconds to enter recovery to restore your device (whicht does not work) and (3) your device will stop start if tehre is no operation. TRWP does not work the only thing i can get to is fastboot and rescue mode. i went trough the steps from OP but at the point where to unbrick (rom b133) with italien knife with the .img i always get failed. im so lost and i hope someone can help me :(
[Mate 8 General] Samavb:
Unbrick Huawei Mate 8

Sorry to hear that. Don't worry. I will try to help you. Please provide me with the information.

phone model -? L29 or AL10

Full build number - before it gave you problems (example: L29C432B560 - > this is full build number)

You need SRK tooks, Italian knife. & you can find stock firmware from this thread https://xdaforums.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727

Since you have fastboot mode working, we can get your phone back.

And please charge your phone, without battery we can't do anything.

You mentioned - it is showing "failed verification"

To fix this you need to unlock bootloader again. Yes again. Only then that red message of verification failed will disappear.

you can unlock bootloader using SRK tools.

Do the following if your failed verification message is in red color

Switch off the phone

Press volume down & then connect to PC.

And then open SRK tools

Type 000 (to enter into command prompt)

type fastboot oem unlock xxxxxxxx

xxxxx -> is your unlock code.

:good::good:
[Mate 8 General] noway023:
so first dumb question how can i find out the full build number?? :(

second dumb question how can i get the unlock code? :(

And i have NXT-L29
[Mate 8 General] Samavb:
Unlock bootloader + Huawei Mate 8

Ur Qs are not dumb at all. I appreciate U for asking Qs. So don't worry, U can ask any number of Qs. Our goal is to fix Ur phone.

1) Build number - > you can find it in settings - > about - > build number.

But I think U r not able to go inside ur firmware. is that correct?

So do U remember what firmware was on Ur phone before Ur phone gave trouble? This is very important

2) For bootloader unlock code you can try one of these two websites

Link 1

https://emui.huawei.com/en/plugin/unlock/index

(this will ask you for Huawei login) once you login. copy and paste the next link.

Link 2

https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail

Check the screenshot - > unlock page. this is where you will come. check "Accept" & then click on "next"

then you will come to a page where you need to provide your details. ( check the screenshot - > provide your details)

Here you need to provide

Before EMUI 5.0 or Since EMUI 5.0

Select Before EMUI 5.0 if your firmware is marshmallow. If you had nougat then you have to select Since EMUI 5.0

Product model - > you find it in Phone users: Go to Settings > About phone > Model number.

Serial number -> Go to Settings > About phone > Status > Serial

Product IMEI - > 1. If you're using a China Telecom or full-frequency phone, enter your MEID. If not accepted, try the IMEI, IMEI 1, or IMEI 2.

2. If you're using other phone models, enter the IMEI or IMEI 1. If not accepted, try the IMEI 2.

Product ID - > Open dialer - > type *#*#1357946#*#*

This is the procedure. You have mentioned in your post that you are not able to get into the phone. So I don't know if you can unlock your phone.

But if you do then it would be great and we can try more troubleshooting steps. Ask your father in law if he has the unlock code. That would save time. Also ask him if he has the original box of the phone there you can find many more details.

Switch off your phone.

Connect your phone to charger

Then press hold the volume up

You will enter Erecovery I hope you do.

See if this is possible. Then try to connect to WIFI & download the latest firmware.

Hope you make some kind of progress. Pls share your steps and give me as much information as possible about your phone especially phone to help you better.

:good::good::good::good:
[Mate 8 General] noway023:
wow this stuff is all new to my never had problems unbricking a psp oder a wii but this is a whole new lvl. :(

nope sry there is no chance to get in to the firmware the only thing my father in law remembers is that the build is nxt-l29c432b320

and i dont know if it had marshmallow or nougat, and the next thing im from germany so i just registerd my huawei id to hong kong because there was no germany to select.

and what the heck is IMEI or MEID :(
[Mate 8 General] Samavb:
IMEI

IMEI number is like thumb impression for humans. It is unique

Your phone has 2 IMEI numbers for 2 sims.

Google definition.

""Every phone or Mobile Broadband device has a unique 15 digit code, called an IMEI number. You might need to find your IMEI number if you want to unlock your device to use with other networks, or for some insurance policies. You can find your IMEI in the following ways: by entering *#06# on your phone's call screen.""

Good that we know Ur build number

L29C432B320

Your phone model is L29 , C432 is European version . B320 is firmware version.

This is EMUI 4.1 version and it is marshmallow. That saves lot of trouble and opens up few options.

Now

Switch off Ur phone

press and hold volume down button & connect it to computer/laptop

Then you will get into fastboot mode or rescue mode - both are one and the same.

Take a photo of that screen and post it here.

Did you try the Erecovery method that I mentioned in my last post? if not, pls try and see if it works.

I mean this

Switch off your phone.

Connect your phone to charger

Then press hold the volume up

You will enter Erecovery I hope you do.

See if this is possible. Then try to connect to WIFI & download the latest firmware.

Pls try these and share how it is going on.

[Mate 8 General] Samavb:
options

To solve that E-verification error you have to unlock the bootloader once again. Then that error will go away.

Since you don't have bootloader unlock code and can't get it. We have to try something else.

Download SRK tools from here https://www.androidfilehost.com/?w=files&flid=119495 you need this tool for everything.

Extract in a folder name it SRK.

Now download the stock firmware L29C432B320

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1076/g104/v51770/f1/full/update.zip

Now put this zip file in the SRK folder.

Switch off your phone.

Press volume down and connect it to your laptop/computer.

You will enter the fastboot mode

Open SRK tools on your computer

Type 000

you will get command prompt

now type

adb sideload update.zip

that update.zip is the stock firmware file you downloaded from the link above.

Try this and share what happened.

Huawei Mate Drivers required

ok

Looks like you don't have drivers installed for your Huawei Mate 8

Install the HiSuite - this should install the drivers also.

I am sorry, I apologize. I thought you had all this ready on your laptop/computer.

After installing Hisuite - you should get the drivers too.

You can also find more drivers in this site

and uninstall all the three.

Then download and install this minimal adb and fastboot tool

https://www.androidfilehost.com/?fid=745425885120698566

Previously, I asked you to download B320 or B180. I hope you have either of them.

1) Now extract that zip file B320 or B180 and you will find update.app

2) Use the Huawei Update extractor software - Link to download - > https://mega.nz/#!QUojHSIa!SCZn2zd-b...iJ7ToCJ3LzKYF8

3) Open the Huawei Update extractor and search for the update.app

4) you have to extract boot.img , recovery.img & system.img from the update.app file.

Then follow the steps as shown in this video

[Mate 8 General] Samavb:
Flash stock recovery - ADB

You know that command not allowed - that is related to that e-verification error red message

You need to unlock bootloader.

or you need to dload B320 or B386.

you can try the steps for L29 model in the first page of this thread but I feel it will once again come back to this e-verification error.

Another way is flashing the stock recovery. That you can do by extracting the recovery.img from B320 or B180. Then using ADB commands you have to flash it. But for this your devices has to be recognized by your system.

to check if your device is recognized.

try this command

fastboot adb devices

Use the Huawei update extractor I gave you in my previous post.

Extract recovery.img and place it in SRK folder.

ADB command to flash stock recovery

fastboot flash recovery recovery.img

That minimal adb and fastboot tool is very important. Please install it if you haven't already.

:good::good:
[Mate 8 General] noway023:
the minimal adb and fastboot tool is installed, this is realy kickin my balls, every step you bring, brings up hope and then the phone smacks me in the face :(
[Mate 8 General] Samavb:
adb

I am very sorry :(

You can see my posts I am trying everything I can to fix your phone. My back is breaking too as I am continuously searching for some idea that can fix your phone.

You need to unlock that bootloader and to do that you need to use adb commands.

And to push adb commands you have to get your phone recognized in SRK tools.

So please check the adb software and Huawei mate 8 drivers. It has to recognize your phone

How to check if your phone is recognized?

type the following command in adb

fastboot adb devices my mistake

command is

fastboot devices or adb devices

And it should give you an answer.

Unless your phone is recognized in SRK tools it is difficult to move forward.

I am sorry once again but this is the situation.

:good::good::good:
[Mate 8 General] noway023:
i hope this is what you mean
[Mate 8 General] Samavb:
fastboot adb devices

try the command

fastboot devices

or

adb devices

you can also check this tutorial

https://www.youtube.com/watch?v=QRfY7NM-s6I

it should return some code and should not give you empty answer. If it is giving you some code then your device is recognized but if it is returning you empty answer or saying no devices found or anything like that then your device is not recognized.

install this universal adb driver and try again all the adb steps

Hi, I have tried all keys to get my NXT-L29 to fastboot or bootloader mode, but it doesn't work. Can only restart. Doesn't power off. And I obviously can't proceed. Any solution please?
[Mate 8 General] CStadler:
Hi, I had a simmilar problem, i upgraded to nougat via twrp and the installation got corrupted, what worked for me was flashing the marshmallow emui boot.img and then flash twrp recovery for marshmallow emui. Via twrp you can then use MTP mode to copy emui 4/4.1 to you internal storage, you have to extract the update.zip file and put the update.app (extracted file) in the root of you internal storage in a folder called dload, if it doesn't exist just create it. Ten turn off your phone and power it up and pressing both volume buttons for 5-8 seconds, your firmware you downloaded shpuld now automaticly get installed.

You wil have to unlock you bootloader in fastboot mode before you can do this. You can follow this tutorial to get the boot.img from update.app file...

Many users who were facing this issue - solved it by using option 1 below. you can also try & see if it works for you.

option - 1

wiping system and cache

option - 2

dload to one of the stock ROM for your phone model by using 3 finger rule

You can get stock rom for Huawei Mate 8 from here - >

https://xdaforums.com/mate-8/general/huawei-mate-8-stock-firmware-official-t3391727

1) Download the appropriate firmware for your phone

2) Extract the update.app & place it in SDcard in the folder named -> dload (you have to create it manually)

3) Switch off the phone - and then press volume + , volume - , power button simultaneously

option - 3 (don't use this. try option 1 if it doesn't work , then option 2 , if both dnt work then this option ) ( this is risky option)

Unlock bootloader - if you have a message in red color when you switch on the phone then you have to unlock bootloader using adb

fastboot erase cache

fastboot erase userdata <- this will wipe sdcard

Bricked Mate 8

Hello guys,

I have a really big problem. I wanted to debrand my chinese huwawei mate 8 (al10) to the european version.

Unlocking bootloader worked fine. Then I had problems, to get run twrp so I installed the decrypted one. Then I installed the modified SuperSu 2.79 zip successfully. So then I went to the srk tool, clicked debrand etc. it seemed to work fine, my phone rebooted, but I got a strange error (something with partition). I had to push a "repair" and now I'm stuck in the erecovery. I cannot enter twrp and neither reboot the phone. It always runs into erecovery.

I can enter the bootloader, but I cannot flash anything in fastboot. It says "not allowed".

Can someone help me please, I don't know what to do anymore.
[Mate 8 General] Samavb:
Making NXT-AL10 work again

Before you can think about debranding your mate 8, it is important to make it work properly first. To help you better please provide the firmware or build number you had on your phone before it stopped working. Were you on nougat or marshmallow?

For that try dload method

You can get the stock firmware from another thread in "General" section of Huawei Mate 8. It has all stock firmwares available. Download B386 zip file & extract the update.app from it.

You have to make a folder called "dload" on your SDCard. Then put the stock B386 firmware (update.app) in that folder.

Switch off the phone & press volume up, volume down and power all at the same time. It should install B386 stock firmware.

If this doesn't work then unlock the bootloader. Yes try it again.

You can try unlocking your bootloader using SRK tools & then install TWRP ( you can choose the right option based on firmware you have especially if you had marshmallow - EMUI 4.0 or EMUI 4.1)

How to unlock? Open SRK tools - > type 000 to go into command prompt and there you can use adb commands to unlock your bootloader.

fastboot oem unlock xxxxxxx ( xxxxxxxxxx is your mate 8 unlock code). It will do a factory reset.

There are two types of recoveries.

1) Erecovery - is when you connect your phone to laptop/charger and then press volume up + power button - It will enter Erecovery

Here you can connect to wifi and download firmware from Huawei servers. directly.

2) Stock recovery - is when you press volume up and power button "without" connecting to charger or laptop. Then you can enter stock recovery.

Hope this helps. If not, we will try something else. :good::good::good::good::good:
[Mate 8 General] spikerspike97:
What do you mean by properly?

I had the official al10 b577 nougat version on the mate, until then all worked.

Okay, I'll give it a try! Hooefully this will work, because I had already created a folder dload. However I can reset it via bootloader as you mentioned.

I tried to flash the twrp, but my phone is running emui 5 right now and it always stucks on "your phone is booting now" unless I used the encrypted twrp version.

Thank you for your suggestions. I'm going to try them out this evening. I'm going to report back!

Edit:

So after I unlocked the bootloader again, the phone started normally. I then checkt my version. I am on NXT-L29, so debranding worked, BUT my build-number now says NRD90M test-keys.

So after some research, I now try to rollback to Android 6 MM again and then probably update.

Btw, I am not able to flash a rom via Twrp (tried especially B581)

Edit 2:

Okay, finally all worked as it should. *Yay*

So after I stuck on NRD90M test-keys, I rolled back version b320 and all worked! I now have the l29 version and a "real" buildnumber. There are now also all gapps preinstalled.

My bootloader is locked again and recovery is on stock too.

I'm now updating the firmware via OTA, I'm just curious if I'll also get the new nougat version. I wanted to unlock my bootloader again, however it didn't work with my Unlock Code (had it from DC). Do I have to redo it with DC if I want to obtain a unlocked bootloader?

Edit 3

I received the ota for version b560 nougat! Perfect, it problem is solved for me!

Thank you [MENTION=3292577]Samavb[/MENTION] for giving me the imput, I probably were still searching in the internet!
