Ok. I will be updating this post everytime I find something that concerns XB360 hackers as a whole.

-------------------------
Dashboard Update: Playing ANY of these games without patching (Assuming you are using a modded disc, DLC added disc, or you are a pirate) will flag you for ban. If you own the retail copy of these games, you won't have any problems.
-------------------------
AP2.5 Extended to:
Call of Duty: Black Ops
Call of Duty: Modern Warfare 2
Halo Reach
Need For Speed: Hot Pursuit
Assassins Creed: Brotherhood
Fable 3
--------------------------
Update Errors: These are more caused by idiocy than anything else. If you get banned from XBL because of this, you deserve it.
--------------------------
YOU MUST BE ON LT+1.9 to update.
Updating while you are on LT1.1+ will give you an error message and flag you for the October/November Yearly Ban Wave.
