And then it becomes tricky, I unfortunately can’t think of a solution. Maybe the tablet shows a screen via the HDMI port? Have you contacted Chuwi about this?
I’m curious about the outcome on whether you can solve this or not. I’ve messed up the USB port in te past, luckily a reflash of the BIOS resetted all options, so it’s working again now.
usually when it just show black screen after edit some bios config, i fix that by displaying output to monitor via hdmi port, go to bios menu and back to default bios setting, and then restart.
unfortunately my chuwi’s hdmi port are broken some month’s ago, so it can’t output display to monitor again now.
well.. maybe i have to buy new tablet and never do editing bios again next time..
