I’ve been having boot loop issues with my UHK80 since I got it, with both halves. It would randomly start boot looping after “freezing up” while being used. Either half would just stop responding and then start cycling. I would fix it by plugging in power to that specific side, which seemed to stop it (unplugging the dongle and resetting did not help - it would just reset and the loop continued).
Today, the right half of my keyboard is no longer responding or booting at all after exhibiting the freezing behavior. The screen is now off, it is no longer looping. The back of the keyboard half is hot and is now cooling down, so I am assuming the controller either just died or overheated temporarily.
I use the dongle. The keyboard is not detected anymore via USB. Yes, the batteries were charged.
Surprised nobody else has described this happening. Don’t really know what to do now…
