Don't demand fast answers, please. This itches me.

Well, avrdude didn't recognize the code it has burnt. How old is the 328P on your board? The Flash ROM has a life cycle of abt 10.000 erase/flashs. But if this is true for your uC no man really knows - I once had a 1284P which was fried after 6 Month of extensive flashing wich I estimate has been 5000 cycles max.

Do you have another 328P? Then test this uC. But be aware the 328P needs a bootloader-sequence too, otherwise it is not recognized and you probably get some sort of stk-500 error.
