Try connecting directly to the K3 and not to the P3.

Subject: [Elecraft] K3 Woes Continue!!!

Good Evening,
This is Mark Griffin, KB3Z. I am having a problem with updating the K3 
Firmware. I have a black screen with MCU LD on it. The TX light is flashing 
red. My usb to serial port cable is a prolific cable. My computer does not have 
any issues with this cable. But for some reason the K3 Utility is having a 
problem where it says attempting to contact K3 and it goes through the various 
speed settings. I have disconnected the power from my K3 and followed the 
Forcing a Firmware Download to the letter T but if my computer can't 
communicate with the K3, all is lost. Right now I have the cable attached to my 
P3 and the P3 cable is attached to the K3. I have called Elecraft, and waiting 
for Dave to call me back. Hopefully he will call me. I do not understand why 
the PC will not communicate with my K3. Why Elecraft doesn't have a button to 
push to just reset the radio is beyond me. If I sound frustrated, I am! Mark 
Griffin, KB3Z _____________________________________________________________
