I have a friend that has a xbox 360 that will not read the DVD rom? He asked me to fix it. I ordered a new one and replaced the drive and know it will not read the disk. Did some research and found out that it has to be the same model as the broken on. With that being said I read how to flash the DVDROM and think I can do that. The problem is I don't have broken DVD Rom to know which model was originally installed in the xbox. My question is their a way to find out what the original DVD ROM firmware was from the Xbox with out having the Brocken or the original DVD ROM? So I can flash the replacement with correct firmware.
