EDIT: The prestige address seems to change, so you can do it the way I previously did it:
1. Set your XP to like 99999999.
2. Check the "active" box on CE so that it stays that number.
3. Keep prestiging until you reach 10th.
4. You win!
thanks for the offsets they still work as of today july 8 2015 anyway you can get offset for time played
