And if the rrod error is still 0021 without the drive plugged in then it is just a coincedence that it happened when i flashed my drive. i say this because it shows the rrod even when i turn the box on without the dvd drive connected. just wasnt sure that if the drive timed out then it needs to "retime itself" with a functional drive before the error will reset itself.
Take the circuit board out of the dvd drive and check for shorts from each places you soldered to ground. I think you have a short in the drive and that short has now damged the southbridge. I can install a new southbridge chip if you want. I just got a new very nice machine for BGA rework and would like to try fixing some more interesting problems. PM me if you're interested.
