I really need help please

Hi everyone , well i am a bit new on this forum and i'd like some help please,

I need someone or some hack to make me go back to level 1 ! because i am level 70 PRESTIGE 6 and i don't want.

So i tryed deleting the stuff .STAT and userdata/numbers/numbers/Remote and other one but it didn't work i'm still level 70.

After i used EA and it made me go back to one so i started level uping to like 5 and i went off, woke up i was 70 prestige 6 again

Anyone know what to do ?
