When I returned it to the original instance is was not seen as a TBR. To fix this I tried to reflash it from the Home Assistant site but it will not connect. Please can someone help me 🙂

Make sure it detects as USB device, if not check the cable works

Yes, it detects the device and shows up but will not connect
