I downloaded the factory reset image from https://echo.danctnix.org:7269/danctnix-...527.img.xz, wrote it to a microSD card and verified that the image written to the microSD matched the uncompressed downloaded image. I then booted from this image using the serial dongle starting with "SD BOOT" to ON and switching it to OFF once the kernel started booting (also tried it lots of other ways!). The output on the serial console shows a different Linux version being booted, still has the drm crash, shows the eMMC being detected, there's an error about "GPT:Alternate GPT header not at the end of the disk." but I guess that's normal due to the nature of the image, then the log messages stop at "Starting network: OK", a bit later get "[ 86.239708] random: crng init done" and then nothing else happens. I'm not sure what is meant to happen but I'd expect some messages on the console about it flashing the factory image. Perhaps it is meant to display something on the built-in screen? I left it for over an hour but when I ejected the microSD, rebooted and it booted into the same unchanged system I'd left on the eMMC; it had not installed a factory version of the image. I'm guessing that the broken built-in screen is breaking the factory reset install process or maybe options appear on the screen and you have to choose to do the factory install?
Unless that drm crash is normal on boot up then I'd say this proves the screen is broken because it was a different Linux version, nearly certainly the factory image reset installer one. Let me know if it isn't enough proof and what else I could try.
