I bought my 360 about a year ago from a friend of mine. It's modded but never been updated I think. It's the fat white one. For newer games I've had to insert a kind of boot disc first and then the game disc for it to work. Today I went over and got a pirated copy of Skyrim. I inserted the disc and I got a message saying that in order to play it, I needed to update. So I updated the system using a flash drive. Now none of my games will work. I can still access the HDD so I haven't been banned, but every time I insert a game disc I get thrown back to the dashboard, or I get a white screen that says "TO play this disc, put it in an Xbox 360 console." I know there are threads similar to this one but the error message I get is different for some reason. I think I might need to get it re-flashed, but I'm just not sure. Any help you can give is appreciated! Thank you!
