Need help w/ 360 modding without mod chip

How much modding can I do with my 360 and 360 games without a mod chip using a usb. I have been using Horizon, Modio… Anyone that’s willing to help me out is appreciate it… I have used some gamesave mods for Cod Ghosts, but would like to do so with bo2 and halo reach and 3…

Gamesave modding is pretty much all you can do.

Without a Jtag or RGH modified console all you can really do is use Horizon and other save editors to mod, as well as using pre-modded saves you can download online. That’s about it. And please don’t create multiple threads about the same thing.
