Try connecting a 2 Mhz crystal (Any other crystal below 16 Mhz will do ) to the oscillator pins of the chip bieng programmed and then try. Good luck.

Hai

Most Probably you have messedup with fuse bits, (disabling serial programming)

BTW what programmer are you using for programming

MicroCon

Yes..you are correct. 10 Mhz will do the work. If didnt work try any other crystal below that. After connecting the crystal, you have to erase the chip, program it with the default fuses and then the chip is reday for next programming. Good luck.
