My Pixelbookgo recently has this screen issue after accidently erashing flash memory using flashrom -E. Even though nothing shows up on the display screen,
(white) light is on when the power cable is plugged in and
serial consoles (e.g., /dev/ttyUSBX) are still accessible via suzyq cable.
I tried several things to resolve this, like pressing key combinations, re-flashing (and rebooting) ec from the workstation connected with DUT, etc, but unfortunatley nothing can recover the screen.
I hope this is not a physical HW issue. Any help at all would be greatly appreciated. Thank you.
(I just attached "version" information below just in case.)
