Yeah samson, the best thing to do is to get it modded at a respectable place and make sure you keep up to date with what’s going on. (Might need to re-flash drive again)
I know that the main reason why most people get caught is because they start playing a burnt game on Xbox live when the game isn’t even out yet.
The best thing to do is to wait 1 or 2 weeks after the game comes out and then start playing it on Xbox Live. But I’m pretty sure if you start playing a day after, you’ll still be fine.
And all that happens is you get banned from Xbox live, which means you can NEVER go on Xbox live again. I don’t think there are any fixes after you get banned.
