 Not sure what is wrong with the dd images or wiki instructions, but I
 reinstalled my BPi M1 manually the other day without issues.
 
 I do see the screen corruption from your screenshot, but only for a second or two.
 I think it might be caused by kernel debug messages before initializing framebuffer console.
 (Is the HDMI device using an uncommon display resolution?)
 
 Anyway, here are the steps I used to prepare the boot partition from scratch.
 Maybe you can use it to find out what is wrong?
