I didn't seem to find this on the forums anywhere. So in my effort of finding something to contribute to the community, I figured I would post a tutorial I made on another website. It's a copy and paste, so if anyone has any formatting suggestions please reply.
This guide is for pretty much getting easy gamerscore points on your xbox 360. It is compatible with xbox live accounts. The exact method varies based on the video game, but I do know a few such as how to get 1k points in Assassin's Creed using the glitch, by loading up the game only twice. Here is the guide:

This tutorial is for performing the spg glitch on your xbox 360. It is for achieving a higher gamerscore by performing a glitch. As usual you should perform all singplayer achievements offline and multiplayer achievements online and try to perform them out of order as to not arise suspicion from Microsoft.
Disclaimer:
I nor any brewery member will be held responsible for your actions. There is a possibility of getting your xbox live account suspended or banned by performing this glitch. Don't do anything stupid and you won't get caught I.E. don't get 50k gamerscore in one day. I have made this tutorial for informational purposes only
You will need:
-Two controllers
-A way to transfer the profiles to your xbox's hard drive.
-The game
-The profile(s)
You can find profiles with several achievements for a given game on several websites including here. Not all games work with the spg glitch and require a gamesave.
Steps:
1. Sign into the source profile, this is the profile that has all the achievements, with controller #1.
2. Start the game up if not already.
3. This is the step where it varies in games. Some games require you to sign in during different loading screens. But during the loading screen (whether for the game's menu, or loading a level) quickly press the guide button on controller #2, then press the "x" button. Using controller #1 now, scroll down to the destination profile (the one you want the achievements to appear on) and sign in on controller #1.
4. Now press B on controller #2 if the guide is still up.
5. Once the game/level has loaded you should receive the achievements! If not some games such as COD4 require you to beat a level, kill x amount of people, and what not. It just depends on the game and the achievement. Just experiment with it and you shouldn't have much of a problem
A lot of games that require different means of getting the achievements will include a readme telling you how to perform the glitch. If you have any problem just ask!
