I got a problem with updating my M3 Lite: First I unlocked the bootloader, installed TWRP 3.2.0-0 and then lineage-16.0-20191112-UNOFFICIAL-bach.zip without Gapps. Booted into Lineage and everything went fine.
After that I installed via TWRP version 3.3.1-0 of TWRP and rebooted into TWRP. Then I reset the M3 and installed via Fastboot TWRP 3.3.1-3 and tried to reboot into TWRP but had no luck. Now I'm stuck with the screen saying "Your device has been unlocked and can't be trusted". Wether I try to boot with holding Volume Up or Volume Down, I always got back to that screen. Unfortunatly I can't even get into Fastboot mode.
Did I brick my M3 Lite or has somebody a clue how to fix that bootloop?
