it seems like your unifytv device problem, ask telekom for fix


a few things to try,
1) when flashing, turn your HDMI switch off then on

2) try connect your unifyTV to first port of the HDMI switch

3) could be HDMI cable problem, rotate your HDMI cables to see if the problem show up in other device
