[Elecraft] K3 :: firmware update failure

[Don Wilhelm]

  Steve,

Are you using the latest K3 Utility?  If not, download that first.
Then follow the instructions in the K3 Utility help file to force a K3 
firmware load.  You must unplug the power from the K3, not just cycle 
with the power button.

If that does not work, perhaps Dick will help you.

73,
