All of the sudden my ATmega328P stopped responding to flash commands with avrdude.
Here is the output of the attempt:
avrdude -pm328p -P/dev/parport0 -cstk200 -v -F -Uflash:w:./bin/main.hex:i

avrdude done. Thank you.

I've used this micro for more than 1 year. But I don't think I've depleted its 10000 flash write/erase cycle count.
Last thing I've done was re-programming fuse with Reset Disable programmed:
avrdude -pm328p -P/dev/parport0 -cstk200 -Ulfuse:w:0x62:m -Uhfuse:w:0x59:m -Uefuse:w:0xff:m -i960
How can I bring my micro to life?

Disabling the reset means game over for serial programming because it is used to enter ISP mode.
ATmega without reset can be accessed only by a programmer which can do high-voltage parallel programming, such as the AVR Dragon. If that micro is soldered in a circuit, it is highly inconvenient method and usually not worth the effort.
