[Elecraft] K3 - stuck at MCU LD we upgrading software

[Clay Autery]

I'm new to Elecraft (1 year), but with almost 30 years in IS/IT...

I always do the best I can to minimize potential problems when flashing
firmware.

This includes using a laptop or computer running with a truly
uninterruptible power supply.  A fresh COLD reboot of the computer and
radio for EACH flash.

Oh, and as suggested in the manual and/or the Cady book...

BACK UP YOUR FIRMWARE and SETTINGS!!

I save mine every time I make a change.  Storage space is cheaper than
keeping a log of changes between downloads.
