[Elecraft] KX3 bricked by F/W upgrade attempt

[Matt Zilmer]

It doesn't sound stupid at all, Rick.  I just went through the same
exercise with a K3 I'm rebuilding.  On loading it the first time, the
load failed mid-step.  Trying to redo the firmware load, the utility
couldn't even find a K3 attached.  But it was because of the state of
the serial port driver (or hardware maybe), not some failure at the K3
or within the K3 Utility program.

In this case, I only had to exit the utility and cycle power on the
USB hub with the serial converter attached.  After doing that, the
utility found the K3 in its "waiting for firmware load" state.

This same scenario has played out with the KX3 as well.  Rebooting the
computer with nothing attached at the serial port would (should) work
just as well.

73,

I also suggest that you do not have the computer attached to the radio during the (radio or computer) boot process because on occasion, the USB device reader (what is attaching?) may 'read' the device improperly and attach the incorrect driver.
