the sd-card became corrupt. works again!
My E1 is acting super weird. There’s no logo screen when starting and almost all text is garbled, like random bitmaps. Could it be that I screwed the bootloader / firmware / ram? Also befor that I got a lot of hangs and freezes when working on a patch.
I tried connecting it with the middle left button pressed and reapplied the firmware, no change.
E1 mk1, firmware 3.5
