P20 Pro Black screen (Only fastboot)

[fatyus]

Hi friends.

My phone p20 pro
Firmware version: CLT-L29 9.0.0.177 (C185E4R1P11)
Device name: CLT-L29
Oeminfo: hw / meafnaf
Serial N: ...
IMEI:
IMEI2:
Bootloader state: UNLOCKED
Battery voltage: 0

The screen of the phone is black. nothing turns on. you can only enter fastboot fashion. it doesn't go anywhere else. There is no response when you press the power button. the possibility of crashed erecovery. but I can't flash the flas file even though I didn't remove it from the app.
please help.
FAILED (remote: partition length get error)

Did u try restarting your computer and enabling usb debuging again? Sometimes i have to restart my pc for it to see my p20.
Iif hisuite cant even even see it in recovery option i would try funky huawi they can unbrick device

The phone never turns on. Always black screen. just fastboot when I connect to the computer. I can give fastboot commands. but erecovery command '' FAILED (remote: partition length get error) '' gives the error. fastboot reboot again when I come back fastboot again.

The only way I managed to fix this on my device was by using the test point method with dc unlocker, as explained here.
