[f 1i n e s t]

from what i remember the first flash i did was nueroms i forgot what version, then i went onto the kaosrom for like a year then i went back to nuerom because it got too slow, after that i tried cooking my own roms but that didn't go well because the phone kept acting wierd so i went right back to nuerom, and now i tried the dcd's latest rom and the problem still happens, i think this problem started after i tried cooking my own rom and flashing it. what are the steps i can take to have everything back to when i first got the phone?
