[Elecraft] K3 :: firmware update failure

[The Smiths]

Steve , you went through the same exact thing that I did.  I had thought that I missed a step, and then shut down too early or something... I guess this is an issue with the beta software, UNLESS, you start with the P3 off.. This is KEY.
I did the power on button and the reset and NOTHING seemed to work..
 
I had the same issue with the polling not finding the rig.  What I ended up having to do was 1 - Turned off the rig power supply, 2 - Closed the Port in the K3 utility  under the "Ports" tab.  Next I Then went into the windows "Control panel", selected "System", then into the "hardware" tab I selected "Device Manager".  From there I  went into the "com ports" area, and I opened the com port that I was using for the K3.  I checked on the speed, changed it from the default 9600 to 115200 (or 34800 doesn't matter) and I hit apply.  After that I hit okay. Even if you don't need to make a change, change it just to restart the ports brains... 
I then moved the K3 serial cable over to the K3 (and out of the P3 completely)
 
Next  I turned the power supply back on for the K3, then I HELD the power button down for 10 seconds (until the red light started blinking).  After that I went back to the K3 Utility and I went to the "firmware" tab.  I pushed the button that said "check versions now" then low and behold it finaly read the port again on the rig.. I then hit the Download ALL button and everything worked from there.
 
Give that a try and let me know if it doesn't work..I'm sure there's other ways to skin this cat...
