Gary,
If possible, use a real serial port instead of a USB/serial adapter.
If you are using a USB/serial adapter, plug it into a native USB port,
not into a hub.
Close K3 Utility and reboot the computer.
Remove the power cable from the K3 for at least 5 seconds
Hold the K3 power switch down for at least 10 seconds
Open K3 Utility and "Send All New Firmware".
If that does not cure things, check your computer serial connections -
try a new cable, etc.

I am hoping somebody can help solve this.
I attempted to load the latest Beta software when suddenly the
download failed.
Unable to communite with the K3 from the loader (latest version) and
the power off to force a reset and download results in "Unable to
communicate with K3" error msg appears.
The flashing yellow light appeared first, now extinguished, just the
flashing red Tx light, unlit screen and MCU LD in the display.
Anyone have any suggestions to try next?
