Bricked my K3 as well

[Hisashi T Fujinaka]

It's dead. I have it in MCU load mode with the TX light blinking and
"MCU LD" on the display. I can't get communications test to work. Using
the latest utility, trying Mac w/latest driver, Windows 7 with the
latest driver, about to try Linux.

Tried several different cables.

Anything else I forgot?

That fixed things. The Help had more info and a different reset
procedure than in Fred's book: holding down power for 10 seconds. That
and a different laptop seem to have let me reload the beta firmware.

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!
