Hi guys, First of all, I'm pretty much a noob when it comes to modding and xbox software updates so I came on here hoping to get some advise from fellow members. The shop where I bought from sells 2.0 and 3.0 version games and my modded xbox360 is able to play the version 2.0 games. I just bought a 2.0 version Maxpayne 3 game and installed. When it finish installation, it requested for an update which I did and now it can't play any games (disk not recognised) including all my older games which work perfectly before the update. I noticed the Xbox dashboard is different than the one I used to have. My questions are: 1) Is this reversible? Can I get it back to the previous setting or software so that it can play all my games again? 2) if yes, how do I do that? Again, I tried reading up some previous threads but I don't really understand most of the discussion. Any help is much appreciated.
