During initial setup of a new unit, the firmware updater hung for about an hour, so I tried restarting the unit. I got the "looks like something went wrong screen" and tried again. The firmware updater now displayed firmware version 0.0.1 instead of the 1.7x as it initially had. This time when I started the firmware updater, the KK error screen remained on and the unit gave no indication it was actually receiving the update. Again after about an hour I restarted the unit and tried a different USB port. The first attempt was using my only USB C port, so then I tried with a C to A cable and a USB power adapter. Still the same result.
I tried reinstalling the hardware connection service and still have no luck. Now there are no drivers for the Mk iii unit listed in my device manager, and windows gives the USB device not recognized message when I power the unit on, firmware updater just doesn't see the KK unit now.
I've sent in a support ticket, but I'm just wondering if anyone else has experienced this and if they were able to ever get it working. This is quite unnerving to say the least.
