It says version 1.2. I followed the instructions to the letter. I tried doing the 1.3 version also. It says to turn off your scanner and disconnect the programming cable. Then turn on the scanner and press 0, pgm, enter, which I did. The screen on the scanner then reads IC/IF interface, upgrade, (or something close to that.) When I try the "test" on the version 1.3 upgrade, it says my scanner is not connected or has "incomplete data" transfer between the scanner and computer. I tried all three ports in the back of my computer to no avail. Not sure what to do.
