Mate, The update couldnt have unflashed your console in the update, If your drives an Hit then there is no firmware update and your drive remains the same... Also the laser in drives can be hard find a good one, Ive brought afew off ebay "for liteon" where the Laser plays originals But never plays backups, even with a Pot adjustment and the console flashed 100%.. Look, the best way to solve your problem is to rule out possibilities and work forwards, So update, Deffo not it has its impossible to effect a Hit drive... Bad media dvd dl discs? Well alot of people always have this problem when they backup a game is to use cheap DVD dl disks, Theres alot of DL disks and most not made for the data of an xbox game, so try different Disks... Also if you have spoofed another drive that played backups with that laser, are you testing an AP25 game? because Spoofed drives dont play AP25 games.. IF i was you and I 100% knew the drive you spoofed plays Backups, I would take the laser from that drive and Put it in my original drive, Its very easy.. This should work..
Like i said before, Benq, Shammy and Liteons with LT on after update, when they try test a backup game they get "Play DVD" error, If your laser is damaged or Even the drive itself damaged it will say "Open tray".. Try listening to your Drive, Does the disk spin? im asking because maybe your motor might have broke in the drive and explains why it says "Open Tray" because its not spinning your disk.. If your original Drive Saying "Open Tray" Not "Play DVD" then its something more then a bad flash or the update effecting your drive, Open tray means "No Disk is fount inside the drive" so either your Laser isnt picking up the disk or The drive isnt spinning the disk but something is telling your Xbox there is no disk.
Hang in there friend, the solution to your problem isnt hard and im sure working together we could fix this for you and get you running backups again, you just have keep at it..
