What to do with a rooted 2.3.6 gingerbread Samsung Galaxy Mini. Can I just flash a rom on it via Odin? Without having to build my phone up from scratch and losing all the data and apps? I would like to flash a custom overclock ROM on it that would keep my phone as close to stock as possible but enable me to over or downclock it with SetCPU. And is there any other method besides flashing a ROM on it to make a phone perform a little better?
