Ok , well I did exactly what you are looking at doing yesterday. Basically just extract the zip file to a folder location on your pc . Then use your ''browse'' in P3 utility under firmware tab to locate that folder.
Ensure the menu advanced function is active so you can select which files will be sent to the P3. The right side column will show the older firmware checked (in checkbox) files against the left column existing new files you have loaded. Use the send checked files to K3 (These should already be checked by default) to K3, and it will go through a firmware downgrade . Then you are good to go. If you do get a mcu ld error with tx light on, then unplug the APP connector power in for a minute & close port on P3 Utility. Then (after a minute) power on holding power button in for 10 seconds until TX ind flashes. Screen will be unlit with mcu ld visible. Close port on P3 Utility, a "firmware required" popup should occur and you can redo the firmware downgrade as previous. Then you are good to go with a good decoder.

However, the K3 utility wants to only go up in firmware so I am not sure how to get it to recognize an older version for installation. I got into trouble earlier and it took me three hours to reboot my K3 as it went dead, I was trying to intall 4.50 at the time and could not get the utility to recognize it. I wasted a lot of time on that one.
