How to Un-Brick a Factory Reset Protected Huawei Mate 9 (please notice underneath the Blue section, this is why I've done this C636 thingy which never happened anyway and got me since wwith this awfull bugy version)

This part of the guide requires a bit of background information to fully understand how and why FRP (Factory Reset Protection) engages on Huawei devices. This is basically an “anti-theft” security feature meant to prevent a thief from factory resetting your phone – unfortunately, it basically locks you out of fastboot / bootloader mode.

FRP tends to be activated when you try to “Reset to Default” in the developer options while the bootloader is already unlocked. The “OEM Unlock” setting will become disabled after you unlock the bootloader, and because FRP is engaged, you cannot change it back. You will need to flash the original stock firmware, which will completely reset your Huawei Mate 9 to factory condition.

The problem is that except for two firmware regions (C636 and AL00) , Huawei Mate 9 stock firmware cannot be directly flashed.

Furthermore, the method for rooting the Huawei Mate 9 involves formatting the Data partition through TWRP custom recovery – unfortunately, much of the Huawei apps are stored on the Data partition (camera, system updates, etc.).

So if your Huawei Mate 9 becomes bricked after unlocking and installing TWRP, you will need to rebrand your device’s OEMINFO to C636, flash the C636 firmware, and use a tool like “Firmware Finder” to flash back to your regional firmware and stock recovery.

blablablabla

I was on a MHA L09 C438b194 and - god knows why if he knows - I ended up with a version of M300 L09 NRD90M which is supposed to have emui 3.1 and android 5.1.

My problems are ... many .

I know first mistake I've done - when twrp worked - was to change the OEMinfo files following a tuto which I don't know why I've done so . yep dumb...if you fear to do something silly... just do(n't) it ?)

So I've change my version from EURO to china or something like that.. well I'm a world champignon ! (oh yeah, a full bucket of it I would say)

First of all no matter what I try from previous ? knowledge ? (huh no what lait-je? what milk I ?) (ex P8,P9 user) i cannot instal TWRP or CWM ...

Secondo when factory reset from android or from Vol up and power button my bootloader , after rebooting the mobile comes back Locked...I get the option development enable, set usb debogage , CANNOT set OEM , reboot and... bootloader unlock . (waaaaoooouuhh)

Reboot again ? try to flash it ? Wrong password or command not allowed (been tryin with everything like SKRtools huawei tools etc..) or boot at risk lol hell yeah you are pal !

Oh as well when i check the android version (5.1) it shows a N of nougat !? :confused: lollipop ?

want an ice cream perhaps?

As well as when i reboot mobile is says the RED message FAILED VERIFICATION and so many other things i probably forget to tell you.. (sorted too !)

ooohh shut up will ya .

Even if I was to trying to relock/unlock bootloader it either ends up with "false command not allowed" or worst : wrong password .

no say about the "failed root type is risk and other many troubles I've been through for the last 4 days ...

I am , of course , terribly disapointed of myself and hopeless.. I didn't want to annoy you guyz with my mistakes as I am a big fan of your work and been reading topics/tuto here on XDA for many years... so tried a lot of solutions from here...

Bla Bla bla is Jeremy Clarckson around here or what ?

So please could any 1 whose got a clue ... help me : first get back TWRP in ( i could back up oem info with it and copy/paste them for my original one MHA-L09 C438 )

and as well get rid of this awfull work of mine and rebrand my Mate 9 to original firmware/stock version ..

I put into your amazing brains my poor and little sorry bump ;( praying you could help me breathing again. I'm desesperated of such ...well dumb me .

Thank you in advance for further help or questions and my apologies for my Frenchglish .

aaaaah finaly you shut it up !
