I seem to have bricked my left keyboard half during firmware update. Probably/Maybe because the keyboard was connected via a KVM switch at that time(?).
I already tried the method described here: My UHK is bricked! What now? - Ultimate Hacking Keyboard, but I just keep getting the same messages over and over until the update process fails with an error (Couldn’t connect to the “Left keyboard half”.). I tried the update process multiple times on linux and windows.
I “bricked” mine in almost the same way, my UHK 60 v1 was plugged in to the monitor. Tried all the things, contacted support and informed them I tried all the things. In the end I had to send in for repair.
Can someone more knowledgeable confirm whether we should avoid K(V)M switches during fw upgrade? For the first year or so I always disconnected it but later forgot it during one upgrade and have not bothered with it ever since.
