[Elecraft] KX3 bricked by F/W upgrade attempt

[Rick Bates, WA6NHC]

This may sound stupid, but reboot the computer and try again.  It might not be the radio not understanding the data coming in the i/o port, but rather it may be the computer (driver) got hosed and isn't sending proper data streams.  Who among us hasn't had an OS go stupid?

Then keep it simple, attach to ONLY the radio directly (you did).  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.

If that doesn't work, then 'prove' that the interface cable is still good (test it).

With all the complexity of attaching various components (OS, firmware, hardware) together, it's a wonder any work at all.

You should be able to get it back to working without EEINT, once the firmware is reloaded.
