K3 died while attempting firmware download

[Gary Nichols-3]

Help please.I killed w8uvz's K3 while trying to download current firmware.
The computer attempted to download three times and then became
non-responsive.  I could not power down the K3 so I turned off the power
supply.  When re-applying power the TX light is blinking and only MCU LD
appears on the screen without backlighting.  How do I get back to a working
radio from here?  Thanks, de gary, kd9sv

I have had this on a number of occasions :-
*** DON'T PANIC ***

The Bad News is that something got screwed up on the recent
firmware download.

The Good News is that no harm was done, and your K3 is sitting
there ready to try again.

My advice would be to restart your computer, check your COM ports
and wiring, particularly if you are using a USB to serial
converter.

Restart the configuration utility, and check that you have the
correct port selected.

Just tick the MCU, and the always load data tables boxes, and try
to download again.

With a following wind you should be back in business.

The radio is in a state where it's waiting for you to load software.
Either try the same version, or back up a version or two and put that
in.  Make sure that your serial cable is plugged in properly before
beginning.

I do this regularly as part of testing the K3 Utility.

Just reload the firmware using the K3 Utility.

Use a computer with a "real" RS-232 serial port if one is available.
