Running CM10.1 now. I'm pretty new to this. And I feel pretty lucky to have gotten this far without trouble. Now I want to go to GB27. Should I unroot, install GB27 via KIES and re-root. Or, is there some way I can install GB27 the way I did CM10.1? I'd really appreciate it if someone here would point me to some idiot-proof instruction here. I'm not having any luck finding this information. Thanks!
