New to this need help!

So like it say’s im new to all this any help would be nice, so i am trying to get a mod menu for bo2 for my xbox 360, trying to figure out if i can do it with just a usb or if i need to find a way to send my xbox off to get it modded so i can load a menu up on it. i would like to just use a usb if i can if i need to pay a little i can do that as well.

You will either need a jtag/rgh or you could try hot-swapping iso mods.
