WARNING
Make sure you read everything before you root. Rooting the phone can trip the knox warranty sensor (this is not confirmed but a possibility), it will (this is not a maybe) increase your flash counter and show you have a custom system status. As of right now, you cannot reset/undo these. So unless the devs find a way to fix this, once your root your AT&T Note 3, you cannot return to 100% stock and your warranty is out the window.
