This is one of the only tools I use that works and doesn't get me banned. For those reading this post:
1 ) Switch to Ps3Ita 4.50 CFW
2 ) Change Mac Address
3 ) Get a PRIVATE Console ID and change your current PSID by editing the last digit or so
4 ) Spoof those by pressing "X" in psnpatch and it will also disable SYS calls
5 ) Open PSNINJA v4 for 4.XX
6 ) Wipe History - Replace History - Make History Read Only (In that Order, if you want to do it again later, first make history writeable again then do it again)
7 ) Make sure you're signed out and have started Black Ops 2
8 ) Go to the multiplayer menu and sign in, then connect this tool with CCAPI (Cex)
9 ) ONLY MODIFY PRESTIGE AND RANK OR YOU WILL GET BANNED! NO UNLOCK ALL! NO MODS WHATSOEVER! I have not been banned in a few days, will update with more information gathered
