Which files to edit in N880E 4.1 ROM

[Guest mitko7411]

Hey guys, I just want to try out the N880E 4.1 ROM but I don't want to brick my device like last time soo my  question is which files should I delete/modify to get it to work. Cuz they say that it's way faster than even cm10 (cm10 is the fastest rom ive ever tested)
