#146 Black screen on x220

Hi. I've just flashed my x220 with libreboot from testing/20221214 release and my screen is not working. It is just black with no image. i tried using flashlight to check screen backlight, but it didn't helped. With old proprietary bios it is ok. I also tried removing ram/cmos battery/ssd, but with it also didn't change either. I tried differen roms with corebootfb and txtmode - no results either

did you insert the neutered ME before flashing

see:

https://libreboot.org/docs/install/ivy_has_common.html

these boards are basically bullet proof, so it's probably that. please confirm

EDIT: to clarify, release ROMs do not have the neutered ME in them. you must add it, using the instructions in the link above

Yes, my fault. I didn't read manual completely. After inserting neutralised me all is working correctly. Thank you for your answer!
