HELP. Issues after Rebranding - Huawei P20 Pro Questions & Answers

Hi all, I need your help please.
I've recently rebranded my CLT-L04 P20Pro to CLT-L29 emui 9 using Funkyhuawei.
After the rebranding the bootloader is still unlocked but FRP is locked
ADB and fastboot commands will not work. I can use fastboot to check bootloader status etc etc but not push commands to write recovery or whatever.
Does anyone have a solution to maybe go back to CLT-L04 ? Thanks

[Solved] Any way to unlock FRP after OTA update? (P10 Lite)

Hello!
I recently rooted my new P10 Lite before version B124 was released, but then I decided to update my phone from B102 to B124 by flashing the recovery image from the Update file and then updating via OTA with the full update files.. The phone updated successfully but yesterday I used adb to boot into the bootloader in order to flash TWRP but noticed that FRP is now locked and i cannot flash TWRP without getting command not allowed error.
I also tried unlocking the bootloader (just in case it was locked for some reason) using the password i got from huawei but even that gives me an error. The enable OEM option in developer settings is greyed out since after the update and is till greyed out even after clearing cache and factory resetting the device. Now is there a way for me to unlock FRP again in order to flash TWRP? Or maybe another way to flash TWRP. Hopefully someone knows a way.
Use DC Unlocker.
I used it to unlock my bootloader on P9. Works perfectly.
They do FRP unlock and supports P10 Lite.
Costs 15 credits so 15 Euro.

Thanks bro. Wish i saw it before spending 15 credits in DC unlocker. Even after removing frp i am still not able to tick enable OEM unlock in developer settimgs or flash twrp in fastboot. Only thing on my mind right now is to lock bootloader and see if enable oem unlock option will be available after that.

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

P10 Oreo and root

I recently updated my P10 VTR L29 C432 from nougat to Oreo B360 via oreoupgrade script method as posted in forum but after update my bootloader seems to be locked again i wanted to root my phone via installing TWRP but it's not allowed by fastboot
Any solution or any solution to unlock bootloader without losing data !? I have too much files and apps on phone that i won't lose
I still have the same problem, created an thread many weeks ago and still don't have an reply. Seems like the only way is to make an backup with that backup tool in the settings (advanced->save&restore) or an backup with hisuite...
There's no way to unlock the bootloader without factory reset.
You can only do a backup with HiSuite or Huawei cloud - but notice: you need to backup DCIM manually!
Just a question, because you said, that you updated your phone with my oreoupgrade script:
Did you follow my guide exactly or did you do anything after the update progress was finished?
I need this information, because if this happens to more people, I need to take a look on the progress.

That's odd. All devices I testeds stayed unlocked after update.
The update won't lock the bootloader by itself - normally.
You're sure, that you didn't lock it manually?
Is only the FRP Lock active? You can unlock this by enabling the OEM Unlock in Developer Settings in the settings app.

Okay, that's bad. I'm sorry for this.
You need to unlock it with fastboot command and do a factory reset.
But don't know why the update process locked your phone while other stay unlocked.

If you don't have Bootloader unlocked just go to Settings /System/ Developer options and switch off OEM Unlock (=FRP Unlock)
Btw, there is no need for panic because of unlocked FRP (and/or because of its warning while booting

You didn't state here but from your another post (you installed RR), you unlocked Bootloader and therefore obviously you had to unlock OEM/FRP
If you don't like unlocked FRP, then you first go back to stock Nougat, re-lock Bootloader and forget about rooting, installing custom ROMs, etc - for all that you must have unlocked Bootloader AND unlocked FRP

On the 'Chinese' Oreo there is no OEM unlock option in Developers Options, and OEM/FRP always stays unlocked - please consult HWOTA7 OP instructions.
OEM/FRP stays unlocked also if going to Open Kirin ROMs and back (if f
the required installation procedure is followed)
Check in Fastboot, maybe only your Bootloader is locked, and you just need to unlock Bootloader again in Fastboot

Ok, be careful to follow OpenKirin installation guide
Btw, there was a trick to re-enable hidden OEM Unlock option in Oreo, post in the HWOTA7 thread:
https://forum.xda-developers.com/p9...date-tool-hwota7-p9-eva-t3820849/post77296996
With root, open from eg MiXPlorer:
/hw_oem/prop/local.prop
find and uncomment the line (remove trailing character #):
ro.frp.pst=/dev/block/platform/hi_mci.0/by-name/frp
Then reboot, open Settings/System/Developer options and find the belowed OEM Unlock option (see attachments)
