Hello I need serious help. I am a total newbie and messed up my phone. I have a SGH-I337 AT&T. I tried to install a cwm recovery but I must chosen the wrong one. Now my phone just says the error message "software not authorized by AT&T." I had kitkat 4.4.2 so I cant use kies to restore phone, and to make matters harder I use a macbook white not windows. Is there a mac solution to this problem? How do I get my phone working again? Thank you to those who help in advance.

You can't put cwm or twrp on your device, don't even try it again. You need the nb1 full Odin tar file. But you have a Mac, which I don't know how to use. Check out heimdall.
See the second post of this for the tar file http://forum.xda-developers.com/show...php?p=50667360

When using MAC, you would use heimdall to flash the stock firmware. http://forum.xda-developers.com/show...php?p=52768803 has the dump for the NB1.

Probably you can extract it and only flash the recovery to see if it solves the problem. If not, you may have to flash the full firmware.
