(adsbygoogle = window.adsbygoogle || []).push({}); Do you have negative stats, or just sick of having the max prestige? Here is the solution to resetting your account!
I believe this works for both PS3 and X360 (On 360 I believe this has to be done through zombies.)
YOU DO NOT NEED BYPASS OR JAILBREAK TO DO THIS!

The Simple Steps with detailed information! (Please let me know if this is possible on 360, then I'll update the thread)
1. Copy over your W@W save game from your PS3 onto a USB.
2. Download W@W Savegame editor (I use Correys COD5 Savegame editor)
3. Click file then open file. Click Computer, USB, PS3, SAVEGAME, Then the BLUS or BLES file.
4. Click on GPAD0_MP on the side and delete everything, then type in:
set gpad_buttonsConfig "BlackCentury"
bind dpad_up "resetstats" (Or put the prestige rank you want) statset 2326 0-11; statset 253 1-65.
set developeruser 1
5. Save the files, and close and copy back to PS3.
6. Start up W@W, Click on MP, go to Private Match and start. When game starts click up on the DPAD, it will say "Your stats have been reset by Treyarch" (Or when you set the rank you wanted, end the game)
7. After that, play online (Any gamemode) get a few kills then back out.
8. Once you have backed out, leave your PS3 on for 3-8 Hours on the MP main menu or overnight when your sleeping. (To update/refresh the servers.)
9. When you wake up, play a game get a few kills and backout, then dashboard to PS3 XMB from the MP menu.
10. When you get back on the game, go to MP, then play a game, and backout then your stats or rank will be officially stuck!!

Hopefully this helps anyone!! Please let me know if it worked or let me know what else you guys want me to post! Have a great life! - BC

Yeah i have horizon, but you can't change much with it other than console numbers and stuff
