See K3 Utility Help, Troubleshooting MCU Load failure. It has a step by step recovery procedure.

Strickland Sent: Saturday, June 30, 2012 6:43 AM To: Elecraft Subject: [Elecraft] help - firmware hangup I have "lost contact" with my K3. I was trying to load the 4.51 firmware when I got an error report in the K3 utility program, and the K3 became unresponsive. Now, the TX light is blinking and MCU LD displays on the lcd. The computer terminal program keeps trying to establish contact with no results. In the K3 utility notice window, the program is continuously cycling through various baud rates with no luck. I tried to reset the radio using the PWR on - press SHIFT/LO 0 [KE7X p32] but nothing happens. I have shut everything down and powered back up but without results. The red TX light and MCU LD is all that I can get. Thanks. ...robert -- Robert G.
