(adsbygoogle = window.adsbygoogle || []).push({}); Ok recently I've been trying to figure this out and heres what I've got so far.

Solution 1:

- After you do the leaderboard hack, turn off your ps3; turn it back on.
- Delete the GameSave data for your MW2 Profile. Note: This is not the file that is 81kb. It is the big file 996kb, something like that.
- Delete the patch data and make sure your not using a proxy.
- Start MW2 and download the New Patch 1.10.
- Now at the Main Menu, go to Spec-Ops.
- Play a really quick mission of The Pit. Finish the round, don't exit out to early.
- While in the Spec-Ops lobby, find a friend and join his session. Note: Must be an online match, not PRIVATE MATCH!
- If it automatically goes to Multiplayer and starts to download the Game Settings, that's good.
- Also it will check for updates; and it will update your profile file (the one that is 996kb), and it will save your Statings.
- Now if done correctly, you should be in an online match.
- Make sure you get one kill, one death, and atleast shot 3 bullets, not FAMAS or M16.
- Don't press Leave, wait till the game ends!
- Now check the leaderboards and see if it worked.

~ If solution 1 did not work, don't do anything, just continue to solution 2 ~

Solution 2:
- Load the offline profile on both controllers (1) & (2)
- Load the error and go to prestige.
- Afterwards load up the non-error.
- Then go to split screen and stay in the lobby for 10 seconds atleast.
- Now click Play Online.
- Play a regular game, shot 3 bullets, die once, and kill one person.
- DON'T LEAVE THE GAME EARLY!

Please don't flame. Theres no tuts on how to do this and I'm just trying to help everyone. IF YOU THINK IT'S SO EASY, DO IT URSELF!
Please someone test this and see if it works.
