I need some help! I attempted to update my FT-891 Main CPU from V01-07 to V01-09. I downloaded the software update zip file and the SCU-17 USB-COM Port emulator. Followed directions for both procedures. When I attempted to update the Main, I keep getting COM port error. I select cancel disconnect power, USB cable, and put the update switch back in operate mode and attempted to turn on the radio . . . it will not come on. HELP!! radio is only 11 months old.
