Help ripping personal Spartan model from Halo 4

[Huntertyavatar]

Just like the subject says, I'm trying to rip my spartan character (the guy in my avatar) from Halo 4 on my Xbox 360, so i can rig his model in blender and use him for stuff. Unfortuantely, I have not found a single guide or video about doing so. There were a bunch about ripping from 2 and 3, but none about Halo 4, and especially none about ripping specific spartans out of the game, like your own Spartan IV. Closest on here i could find was a guy saying the models can be ripped about 2 years ago.

If anybody here has any idea how to do this, that would be much appreciated.
