Thank you for the reply DoctorM!
The problem is that Prokupan's rescue package does nothing for me. Tried rupor-rescue as well. Nothing is being displayed on the screen, on boot it flashes a few times and then nothing, the yellow light is blinking and then reboots. I guess it's in a boot-loop.
Basically, I can't get it to a state (recovery mode) where I can access it via
USB.
I might have bricked it to a point where nothing can be done... But I prefer
to think that there is a solution for every problem
