[OnePlus 6 Questions & Answers] martinforum:
Hello,

several weeks ago I bricked my oneplus 6 during the approach to install lineage 16.0. I also tried to fix it, based on some articles I found, but without success.

Error - most likely I have coincidently wiped the partitions a/b...

A) So, some weeks later I want to bring it back to life. Current status following the lineage instructions:

1) unlocking bootloader

is unlocked

2) temporarily booting a customer recovery using fastboot

- sudo ./fastboot devices

977d3806	fastboot

- sudo ./fastboot flash boot ~/Downloads/oneplus6/twrp/twrp-3.2.3-1-enchilada.img

Result: power off, volume down + power, same result

B) Alternative

C) I also tried [ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6 – also without success. Basically everything seemed to be ok but after the end I had to manually reboot it: nothing happens - only dark screen and white light close to front camera.

Flashing looked good:
