[Elecraft] K3 Bricked HELP!!

[Bob DeHaney]

Trouble started with no reception on 14 or 24 mHz.  Reloaded configuration file which got reception back, but had a continuous ERR PTT.  Attempted a complete firmware reload.  K3 hung at MCU LD with all buttons inoperative.  I then tried the recovery procedure in the K3 Utility Help section.  The K3 comes on without backlight, and transmit blinking and MCU LD in the display.  The K3 Utility cannot open the port.  I’m stuck.  This K3 has all K3S upgrades including USB, etc. I have also tried rebooting the computer with and without USB connected.
