Everybody knows how to do prestige glitch with UDP flooder, so I skip this part. Right after finishing prestige duplication, take out the disk pressing eject button. Sign off, Start game again, Sign in, After connecting online quickly start UDP flooder before pressing 'Play online' button. Click play online and quickly go to public game, search for a lobby. Stop UDP flooder. Play a match. That will stick your duplicated stats.
No offence but this is the worst way & its not how u make it stick. When u do this glitch u think that the way your telling everyone made it stick but it doesn't people its based on your account if it wants to allow you to over write a prestige without bringing the rank error.
Only way to do this without error:
Your account automatically allows you.. not no disk drive eject crap.
Reset your stats then perform the glitch.
