P20 Pro (Clt-L09) Hard-Brick, can not solve for a week..

[draligus]

Dear Friends,
I have Huawei P20 Pro (Clt-L09) with firmware of "CLT-L09 9.0.0.108(C432E5R1P7log)"
It was my last firmware.
I have formatted my phone.
It has an unlocked bootloder but it has a locked FRP.
My phone is bricked now.
I can not install any firmware because of locked FRP.
I have tried the most of the things i have seen in internet.

I can not install any firmware.
I can not install TWRP.
I only have fastboot&rescue mode.
Do you have any solution for me?

Thanks for your troubles in advanced.

I have installed HCU client.

Has you tried to remove the FRP with methods shown on youtube? lots of them show a work around and need to have a usb c dongle so that you can use a usb stick to install a app you need to unlock.

I have the same issue after to want to downgrade from 9.0.108 ... hard brick. Rescue mode + fastboot...
I try everything and i talk with a lot a people on telegram group... I try to flash every img file, ect... No solution... Maybe the SigmaKey Dongle (Huawei Edition) but 100€.... I send back my phone to huawei and i will wait two weeks. I hope i will go back with a firmware....

I'd recommend using the HiSuite / Funky method.. Its unsupported by funky and costs a few $$ ... but worked wonders for me in a similar situation.

But i thought huawei wouldn't give you warranty with a unlocked bootloader etc

i have solved this problem by flashing pie img files via fastboot.

kernel.img, system.img and recovery_ramdis.img

fastboot flash kernel kernel.img
fastboot flash system system.img
fastboot flash recovery_ramdisk recovery_ramdis.img

reboot after flashing in recovery and take factory reset, then twrp works again.

What do you mean by "pie img files" if you could explain please.

connect your device in fastboot with you pc and flash these files.
thanks locere for the files: https://drive.google.com/drive/folders/1lnWemU5xCAnuocAR1PCXgoVYERo0z5zs?usp=sharing

But FRP-LOCK does not allow this operation..

This method bricked my device.
