P20 lite unlocked bootloop

Search This thread
Hello guys I'm trying to save my bricked P20 Lite but I am running into some issues. I unlocked the bootloader using testpoint but twrp won't flash or boot. Flashing gives me a flash write failure, booting gives me a invalid command error and I can't wipe cache either. I could really use your help.

I unlocked my bricked P20 lite bootloader with the test pin method, then I tried to flash TWRP in fastboot and I got those errors.
Are you sure that bootloader is unlocked? (With unlocked BL you will see that message each time when you reboot: "Your device has been unlocked and can't be trusted").
Have you enabled in Developer menu
"OEM unlock" ?

In fastboot mode run commands :
fastboot oem get-build-number
fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the results.

1. Yes I do get that message that it's unlocked.
2. My device is bricked so that's impossible to enable. I unlocked it after it started bootlooping.
3. Gonna do those commands and tell the results
