I need a little bit of help. Last night I finally flashed my Hitachi 47DH drive with the opa xtreme Hitachi 7in1 v2.1 firmware. Everything seemed to work fine, it passed the flash 100% no errors that I know of. I put my system back together and it seems to be working fine with the exception of Gears of War. I have not even tried to play any backups on the system yet but when I place my original Gears of War in the drive it comes up on the Xbox dashboard as Play DVD. When I try to run the game I get an error message stating that I have to place this disk in an Xbox 360 system. All my other originals seem to work just fine. Does anyone know what the problem is? Should I flash my drive with a different firmware? What is the best firmware out there for my drive? I have also seen the birdy firmware and I think there are probably others. One last question. I think my 360 also did a live update today. One day after I flashed the drive, could that have caused any issues? I would appreciate any help! Thank you!
