I only want to root and keep this stock ROM. I don't even care if it's unlocked unless it has to be. I have read through several guides that all seem to be written over a year ago. Is there a new tutorial for me? I have installed Samsung Kries 3 and Odin. I can usually make a connection though it often gives me error messages that my device is not supported. When I disconnect and reconnect, the error goes away. I can see and use Odin and Kreis 3.
