I have an xbox a friend fixed up for me to play backups. The modification took place about 1.5-2 years ago. Last august '11 a backup caused some problems I didnt get around to fixing until now. I havent done any updates since august 2011 and everything seems to be working fine. My question is how do I go about determining what mod was used so that I can ensure I update the mod correctly. Details that may help determine: There was a snag in the initial mod process due to an incompatible (or something along those lines) DVD-drive I currently have a LiteOn drive according to the yellow wires (not sure how to check what series) My dashboard is 2.0.13146.0 Thanks, anything will help.
