Make sure he is hovering over the prestige mode!
Step Three: Switch the lobby to a combat training lobby, then tell the person to press prestige mode and press more info. (Make sure he leaves it there.)
Step Four: Switch the lobby back to player match and tell the person to enter the prestige. They then should be set back to level 1!
