[Elecraft] Firmware update process stalled K3

[Dick Dievendorff]

Yes, the firmware load was interrupted.

Go through the procedure described in K3 Utility Help, Troubleshooting, MCU
Boot Loader.

Subject: [Elecraft] Firmware update process stalled K3


I wanted to install the latest firmware beta release (4.47).
The process started, on the K3 display MCU LD appeared, but after a while
the message appeared, that the update failed.
The K3 stayed in the MCU LD mode and the K3 utility showed that there is a
communication problem with the COM port.
Trying to reactivate the COM communication failed with all possible COM
ports my ELTIMA virtual port cable creates.
Turning the K3 on and off didn't change anything, the MCU LD mode stays on.
Also reinitializing the ports by turning the computer off and on again
didn't change a thing, I could not get the COM port communication started
again.

Does anybody have an idea how to get back to normal without  starting the EE
INIT procedure (loosing all parameters)?

Thanks in advance for your help!!

Axel, DL3ZH
