All attempts to unlock bootloader unsuccessful - Huawei Mate S

Hi, I've read all threads on the Mate S and other Huawei device forums and I've attempted the following to no avail
1 - Traditional method (SN and IMEI mismatch - Chinese and Eng wesbites)
2 - Huawei Product Generator method (HUAWEI Y300-0000 and HUAWEI Y300-0100)
My device has Chinese info on the back - (UL00) but for some reason the software is L09-C900, and I updated it to Marshmallow B390, the bootloader only says locked in green and not FRP unlocked, fastboot commands don't work (FAILED)
Any help?!

Bootloader Issue | FRP Lock | Root Guide

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 !

Imo, If you change serial.no then your unlock code would be different
Try relocking and again unlocking the bootloader.

Dude i am in a similar situation.
I have the bootloader unlocked but frp is locked.
When you relocked and unlocked was the OEM unlock option changeable (not grayed out, no FRP LOCK) again?

As it turns out, you need to rollback to b182 and then upgrade to N through OTA.
dload b300
dload b182
OTA b386
OEM Unlock, ADB Debugging, USB Debugging
Unlock bootloader
twrp

[HELP] Oreo brick After UPDATE.

Brick Huawei after update oreo
Situation:
Phone LOCKED(Green)
FRP LOCKED(green)
Stock RECOVERY
after boot go ERECOVERY.
How To restore ?
With locked bootloader you have no chance to restore without official Huawei Services via Download in eRecovery or payed services like DC Pheonix tool or FunkyHuawei.
Try the official eRecovery method first. If this doesn't work try it with HiSuite. Your bootloader is locked, that means that it should be possible, because the phone didn't detect any modified files. With modified files or partitions the bootloader won't lock normally.
If you have the code to unlock the bootloader you can search for HWOTA. Its a tool that you can use rebrand the phone. You find loads of guides on here to find out how to get the unlock bootloader code. If you find yourself not able to get the product id, serial number, imei to unlock it you can find it on the box that came. You only really need the imei and you can put it in here (http://www.imei.info/) and get all the other stuff. Then once you have the code you can run the bat in HWOTA and rebrand the phone through its instructions.
can't unlock because FRP LOCK (GREEN).... i was try erecovery method 100% download and failed installation.

[HELP] Will I ever be able to unlock bootloader again?

Hi all. So I recently bricked my device while trying to update to oreo.
What I did was rebrand my device from PRA-LA1 to PRA-AL00X(P8 Lite 2017 to Honor 8 Lite) which was required for updating to Oreo. After that, I typed in the command from TWRP to install the update.zip, but nothing happened so I rebooted my device. It boots up as Honor and my eRecovery and fastboot still works, but my bootloader locked when I rebranded.
As I'm typing this, I managed to connect to WiFi and its downloading the firmware, but what I was wondering is will it be possible again to unlock bootloader again? Because my IMEI number obviously changed since rebranding and I didn't save the unlock code so I was wondering if I manage to unbrick this device if it'll be possible to unlock bootloader again with the new IMEI. Any help will be appreciated.

Huawei P8 bricked with locked FRP & BL

Hi, guys. I have a huge problem and I'd appreciate every kind of help.
As I was planning to sell my Huawei P8 lite 2017 phone (PRA-LX1), I've decided to relock the already unlocked bl for warranty reasons.
After relock and factory reset process, the phone does not restart al all, but it gets into eRecovery mode, asking to connect to internet in order to download a new firmware.
But the problem is there is a "getting package info failed" message.
I've tried to enter in fastboot mode, and both BL and FRP are locked (green color)
I have even tried to use the dload method, but update stucks at 5%.
What can I do? I've searched a lot of pages here before I open this thread.
Thanks in advance.
you may have bl unkock code use it
I have the unlock code, but I cannot use it due to locked FRP.

Downgrade 8.0.0.157 C433 to a DC Unlocker version ?

Hello my friends,
I had an iPhone before so it might be very complicated for me.
As I understand, the bootloader code works only with a specific firmware (I have a mate 10 Pro).
My actual version is 8.0.0.157 C432 (newest).
As I read they updated the xloader to 02 ? On which version can I downgrade to use DC unlocker ? Tried it yesterday but I get a error message that my device is not supported (error code 375).
Or are there other solutions to unlock my boot loader ? Paid already 4 euro for the DC unlocker account.
You can not downgrade a 02 xloader based firmware to a 01 xloader based firmware. Dont try it. It will hard-brick your phone and there is no way to unbrick it. As your bootloader is still locked, you can not use any no-check recovery method to downgrade, but what you can do is get bootloader unlock code by using dc huawei bootloader code app. You have to pay 25€ as I remember and they get your bootloader unlock code using your IMEI.
