That's what I thought, but I've not put SuperSU on the phone before I got started. Now I can't see the phone when I get it connected to my PC (save as a misc device, as above) which means I can't get it across. Is there another way of moving it to the phone using ADB?
Ok, I think I had this wrong. Can anyone confirm... I have to flash the new radio and ROM images via ADB command line right?
Still can't remember when and how I gain root access, but that's no so important at the moment.
