Your 12.2 volts in the third line down above is on the ragged edge of being too low, especially during the "Write" and erase portions of the PCM Hammer process. I agree with kur4o . . . you need a heftier power supply that can do a minimum of about two amps without dropping voltage. I use a no kidding 13.8 volts DC old Radio Shack power supply that can deliver three amps continuously - no problems.
