[Mate 8 General] Samavb:
Unlock bootloader ADB commands + Stock + Debrand

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.

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. :D:D:D:D:D:D:D
