I've had my One X (2012) for about a year now and it is still Android 4.1. This is my first Android phone so I'm kind of a noob but I think I can do it. Anyways, I don't know if there's a manual way of updating but if I can please let me know. I have the At&t version too. If I need to root can someone link a tutorial on how to do it please? Thanks
