hello. I have a galaxy s2 I777 on ICS 4.0.3 unrooted . My question is if I need to root my phone in order to flash the rom supernexus. Another question is in case that I decided to update to jelly bean 4.1.2 using odin or kies, I 'll have to unroot the phone or just flash the update?
thanks for your help
