it's REALLY complicated. u have to have some 1337 soldering skills lol

As everyone else is saying, it is insanely hard to do, and getting an xbox that doesn't have the NxE update usually costs you around 250-300$ and if you are only wanting a Jtag for the 10th mod it is not worth it, you probably won't get your monies worth and it will be banned very quickly, what people need to realize is that you can do other things with a Jtag not just the MW2 10th lobbies.
