To restore the firmware, follow the procedure in K3 Utility Help,
Troubleshooting, MCU Boot Loader.
That should get past the MCU LD on the LCD screen.

Subject: [Elecraft] Elecraft K3s transceiver blocked MCU LD
Dear friends: My new Elecraft K3s is blocked.
When I open the box, connect power supply, in the display appear HIGH SIG.
It was not possible HIGH SIG dissapear, I tapped CONFIG, I looging for a
solution and nothing.
I want resetting the radio hold in shift knob while pressing power on switch
unit and now the radio shows MCU LD, and is totally blocked.
I didn´t save the original configuration from factory before to start
configuratio.
There is not possible communication between radio and computer.
What can I do?
