Have you tried the Help menu item in the K3 Utility Program? Here is one
thing is suggests...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Forcing the K3 into "firmware load required" mode
To force the K3 into a state that it requires a firmware download,
* Unplug the K3 from its power supply for at least 5 seconds.
* Plug the power supply back in.
* Press and hold the K3's power switch in for about 10 seconds until
the red TX LED begins to flash.
* Click "Check Versions Now" on the Firmware page.
* Click "Send All New Firmware".

Forgot I still had a telnet session open while doing a 1.68 to 1.69
MCU firmware upload; the upload failed and everything stopped
responding, no communication between the K3 upload facility etc. The
power button did nothing so eventually had to turn off the power
supply; turning back on and then doing a 'Parameter Initialization'
(page 55 ) powered up the radio but it is stuck in 'MCU LD'. In the
words of Monty Python - "This is a dead K3"
I'm sure it's just in a coma and wonder if anyone here knows how to
resuscitate prior to Aptos waking up; maybe I should play some music
to it, always thought the K3 would be a Frank Zappa sort of radio.....
There must be contingency plans for repairing wiped out firmware such
as would happen if a power cut occurred mid way through a re-flash so
I'm not panicking (yet).
This is always assuming the problem was caused by a serial port
contention of some sort.......I'd closed the ports in Logger32 but
still had the telnet open though not that sure why that would
interrupt the PC to K3 comms.....
