Hi Davidfor,
thank you for helping me out! It works like a charm
I really tried everything, but that GloHD did not react to nothing. Just red LED could be turned on and off. The original 4Gig SD card is broken and could not be backupped. Flashed the Image to a new 4 gig and inserted it. Now it boots up again. Did Updates and now putting her stuff on there again.
