Home Assistant Voice PE won't boot

Just received my Home Assistant Voice PC hardware this morning, but it doesn’t seem to boot. I’ve tried multiple USB cables/Powerplug combinations.

The only thing that does work, is when i rotate the circle dial, the colors of the dail change. So there is power (I also connected a USB-C power meter and it shows that it get’s 5V delivered). Also tried to do a reset as described here, but the red ring never appears (even not after 30+ seconds).

So, it looks like I reveived a DOA. Any things I could try to get it booting up?

Issue was resolved, by reflashing the firmware : Home Assistant Voice PE
