I tried migrating from OpenELEC to LibreELEC on my Asus Chromebox. I watched the video, which was pretty straightforward. I downloaded the file from the Downloads page under "Manual Update / Migration from OpenELEC (.tar)", and dropped that into the Update folder of the Chromebox. So far, so good.
When I rebooted, I got the attached screen. I can't seem to reboot, to get into Developer mode. I wonder if the download file was actually the right one, as the file name seems to refer to Raspberry Pi2.
Does anyone have any suggestions on how I proceed from here? Or have I bricked my Chromebox?
