I have an Xperia Arc since 2011 with the default os(4.0.4).
Lately it started to work really bad (it freezes, it sends sms to wrong numbers and many other stuffs like that) and I want to give him a factory reset. But then i thought why not install a custom os.
But...I have no idea how to do that and what to choose. I remember I tried to root him back in 2011 and got him in boot loop..never tried again..
I'm interested in an os with ability lots of customizations(colors, buttons stuff like that..maybe complete themes? is this still possible?), long battery life and that runs smooth during general stuff (sms, calls, navigation). I don't use facebook and stuff like that or crazy games.
Can someone give suggestion?
Also an complete installation guide for complete noobs? I looked at installation guides around the forum and got lost with kernel, room, flash ... I'm not a smart man.
