But when I go to enter recovery I get a screen saying " system software not authorized by att has been found on your phone" and in the upper left hand corner it's says "secure fail: kernel" what does that mean and how do I get back into recovery so that I can try out cm10.2? What I have noticed that my model number now reads sgh-m1919 instead of m1337is that problem?
You need to read the "pinned" threads in the "general" forum. You will find the answer to the question(s) you asked and many other things you need to know about your phone in those threads. If you don't have a basic understanding of your phone or what it is you are doing to it, you will mess up your phone. Good luck, and please read those threads and use the forum's search function before asking questions that have already been addressed.
