[Huawei P9 Questions & Answers] vinfrix:
UPDATED:

Issue has been solved

( i buy 4 credits from dc unlocker and use HCU to read my boot loader code )

yes i know this is all from dc unlockcer yes they , unbrick my P9 but they also

changed the boot code when you flashed the rom via DC phoenix

im suspecting it that way .

Hello guys. Debranded P9 here

Nougat C432B386 Eva-L09

hw eu :country vendor

Bootloader unlocked and FRP lock

my device gets suffer from a hard brick

and recovered by DC Phoenix. In order to

have a Stable Nougat Firmware i decide to

debrand my phone ......

1st attempt : flashing the (.dgkmts AL10 chinese rom)

after flashing the chinese Al10 firmware

from DCUnlocker (.dgkmts) the device boot and

can be flashed into original stock rom

but the first attempt fails because my

vendor comes from a different build

2nd attempt: flashing the (.dgkmts AL10 chinese rom)

but this time, i decide to wipe NVME and OEM

after booting into system and checking my device

details my IMEI stays the same but Serial No is missing

so i had to use HCU to write my IMEI and Serial No.

and obtain a new vendor from hw eu

after booting system, I start to forced update the

EVA-L09C432B136

then i unlocked my bootloader at this stage

using the same bootloader code from Huawei

FIRMWARE:EVA-L09 C432B136

( please focus on this, i already unlocked the bootloader​

here , and allow the oem to unlock )

status : bootloader unlock

frp unlock

the process is successfully done and after that

i check my device details and perfectly debrand

my P9, after a minute it received an OTA update

from Huawei System Updater ( C432B186 )

I update into it and reboot and received another update

again C432B322 ( Nougat-beta version) and then

received the Final Build C432B386

SUMMARY STAGES:

bricked and wiped oem info / SN rewrite using HCU

1. AL10 Chinese rom >

2. C432B136 ( stock firmware)

( do unlocked bootloader )

3. OTA C432B186

4. OTA C432B322 ( Nougat beta )

5. OTA C432B386 ( Nougat Stable)

status : bootloader unlock

frp lock

I'm into that version C432B386

and now im having a trouble here

flashing the original bootloader code

command : fastboot oem unlock xxx-xxxx-xxx

it says : wrong password

failed to write the command

" is it possible to obtain a new bootloader code ?"

i don't know why the boot code changed even though

i use it in unlocking my Bootloader and it succeed

2nd scenario:

when i try to go to developer options and

go to Allow oem unlock

so that i can be able to obtain FRP unlock

but it is greyed out.

" i've read that if you're on Nougat and you are already

in unlocked bootlader, you will have this issue "

the possible way of unlocking FRP is relocked the

bootloader first and the OEM UNLOCK option will

come out.

i guess the solution is finding a new Bootloader code

but "how?" does anyone knows this?

3rd scenario: flashing new recovery

( expecting to have administrative rights )

i try to flash also the twrp nougat version

but it says verification error

command : fastboot flash recovery twrp3.1.0-3-eva.img

failed

i don't want to end up bricking my device again

I'm having a hard time to resurrect this and I don't

want to happen it again, I'm busy with my work so

i have to asked you guys, finding a best way how

to fixed this..

if someone is having a same situation like me

please participate on the thread and or someone who

already fixed this kind of issue please give us information . thank you !
