so i just recently got a 360 from a friend he did not want it because it kept giving him an unplayable disk error even with original games. He told me he never modded it and i believe him because when i took it apart i discovered it was a samsung ms 25 drive and when i flashed it i did not need to disable the firmguard. i used my usb and ixtreme 1.2 revc to flash the drive. The flash seemed to go well i dumped the old firmware and loaded the new stuff i even backed up the orig.bin file. sadly it kept giving me the unplayable disk error. I have tried reflashing it to no avail. It goes thru the process ok but when i try to play a disk it does not work(dvd's and cd's work fine though) I am at my wits end i don't know how to get this thing to work. I think perhaps i might need a new laser or a new dvd drive. If anyone out there knows what to do or has any suggestions i will be thankful to read them.
