So, I have this modded XBOX 360 with like 100+ games in a hard drive that my friend gave me. I think he got it in Shanghai. It's great, but I got greedy and bought a newer game (the tomb raider sequel) which required a system update.
I went to a shop called V Game in Golden Computer Arcade for the update, which they installed, but now tomb raider is all glitchy with weird flashing lines all over the place, and the other games on the hard drive either won't start or are super glitchy too.
I took the machine back to the shop and the guys said they would look at it, but they just called and said nope, there's nothing wrong with it (though there clearly is).
At this point I just want to recover the games on the hard drive, though being able to play tomb raider would be nice. Any suggestions on who else to take it to, or how to handle the guys at the shop?
