Ive been doing it for over a year now. Havent been caught. Just dont be stupid. Dont play games before release on live, or even connected to live. I usually flash all my 360's with the 12x firmware, 5x sucks and the load times are slow. If you use the ixtreme firmware (Youd have to be retarded not to) the firmware wont allow the 360 to boot games that arent properly stealthed anyway. Before you burn the ISO, Check the ISO with a program called DVDMulleter. Also, i dont know where you heard this from, but it does NOT get rid of the region lock. If you have an NTSC 360, You need to download NTSC releases. Period. No way around it. Or id be playing Oneechanbara Vortex right now. If you have any more questions, Please post back.
