Yikes! Sounds like the ISP gods are very unhappy with you
I'm afraid that I cannot offer any advice. I can only say again that my Uno board no longer requires that autoreset be disabled when programming with ArduinoISP. Before I flashed the chip with the new version of optiboot, my Uno board would not work without physically disabling autoreset. I have only used ArduinoISP to program ATmega328P chips, though.
