.So now i think that i should install a rom..if i can.I tried many method only to root it.,..without success (superoneclick..z4root..nothing) So i ask 2 things..
1)Where can i find a simple guide..very simple, that explain me how to root this phone and install it a custom rom?
2) Which custom Rom (An Android 2.3..or 4.0?) should i install to have a good battery life, the possibility to install new app like viber and, very important, to have a stable phone that doesnt restart randomly? (i read that this happens with some roms).
THANKS IN ADVANCE FOR YOUR ANSWERS!
