[Elecraft] Bricked my K3 as well

[Rick WA6NHC]

I've also found that if you use a USB to serial dongle, that a system 
reboot helps (at least in Windows, all versions, which you did by 
changing the OS).  It seems that sometimes the device driver (even for a 
real serial port sometimes) goes wonky when the app fails to load the 
firmware to the K3.  I suspect it hangs because the data isn't being 
purged properly on a fail to send.  The reboot 'cleans' the driver so a 
subsequent retry often works.

Happy New Year!
