Arduino pro mini (clone) @1Mhz target does not answer
I am closing this thread.

The board is probably not destroyed, more likely are fused corrupted.
There are ways of reviving ATMega328 chip and program fuses back its called high voltage programming. You need to probably unsolder the chip or modify your board (post from tontrack).

Also if you are wondering what to do or not to your Arduino board here is quite interesting page (you wil find it in comment).

I did not found a way how it could have happen but it did.

Anyway Iam done with UsbAsp programmer and ordered AVR pocket programmer. Until it arrives I stop any more attempts.

Hope this helps somebody.
