Heres an old DOS program that will re-set an AtMega 128 to its origanal state. This file MUST be run under true DOS (not in a shell like XPs, Vistas, or 7s).

This means you will most likely have to create a DOS start-up disk with FRBPRG16 on the disk.

This little gem has NEVER failed me yet!

I second that, I've used it quite a few times as well and worked every time!

Not here! it worked for me on 128 not on 256 I dont know why! my problem was buy mistake in jeepers I run 128 image on a 256 after the was done nothing heped tryed avrey posible way of unlocking nothing worked so I belive it was a frid Chip! bu I could be rung!

Take your conversation back to the atmega section please:yes:
