1.) Make sure you have 1 prestige token available (ONLY 1)

2.) Have a friend invite you in the Xbox Live Lobby

3.) Go to Barracks > Prestige Shop > Unlock Gear > Perk 1 > Blind Eye and click it ONCE

4.) You should be over the "No"

5.) Have your friend search for any match and then back out as soon as you are both searching

6.) Now you should still have that pop-up but not be able to navigate UP and DOWN

7.) Go to Barracks > Prestige Shop > Double XP and click Yes

8.) Now you should have another pop-up, make sure you click YES to that too

9.) Look at your prestige tokens - it should now be at - 1

10.) Now you may buy everything from the prestige shop that's available to you

NOTE: You do not have to keep doing the glitch. You may just keep buying anything/everything over and over and you'll notice your prestige tokens going down.

As always, you *may* be banned for this, if the servers are able to detect you going into negative prestige tokens.

Post any problems you may have.
