Power Loss during flashing of Vyper Display - Restore possible? #68

Hey.

I would use the Vyper Display with Klipper. I connected the Display directly to the Raspberry Pi 3b+ GPIO Pins. My Raspberry often gets undervoltage messages no matter which power supply I use, but I didn't think of it :-( The Blue Screen turned on and flashing began, than it turned off and on again multiple times in a couple of seconds. It showed the blue screen again for 3 or 4 times and than it all was black. Before I realized what was happening, the Display didn't work anymore. It stays all black and I cannot flash it over microSD anymore.

Luckily, I can access it with the DGUS Tool and still upload files over serial connection, but I don't know how I can get it back working again. I couldn't find anything on Google. Can someone help me unbrick it?

Can you Access the files on the Displays over the serial-connection? And Write to it?
