It has happened so many times other people have saved me and my time! Let me tell what happened this afternoon.
I had received two old CuBoxes (first introduced 2011). There were several ready-made images available on the Internet. I downloaded some of them and burned them on SD cards. None of them worked. Were both CuBoxes broken?
Off I went and found Michael's web page at: https://jeltsch.org/CuBox . Suddenly, all my problems went away. Solved! By others! Certainly not by me!
Michael had written how to get CuBox up and running! In addition there was an image available at his site! Perfect! I had downloaded wrong images which were meant for another model of CuBox. The manufacturers web site was not that informative anymore. I guess that's because of the old model of CuBox I had.
This goes to show not all contents of the net is crap. Without the instructions from Michael... I'd really had been, eh, pissed off!
