[Elecraft] Help! I have bricked my K3.

[Bill Coleman]

PS - the specific error I get is:

“FPF Programming Failed.

“Verify file source and revision. Turn the K3 off and back on, then re-try the firmware load.”

I’ve re-downloaded the files from Elecraft a couple of times using the K3 Utility. I’ve powered off and on many times.

Suggestions??
