Default Soft Brick please help

So I had my galaxy s4 rooted and rom'd. I went to unroot it so I could sell it via this method http://www.androidrootz.com/2014/03/...xy-s4-sgh.html
Everything passed in Odin, however I cannot get into recovery, it sticks at this screen that says "Software has been found on your device not supported by AT&T"
I can still go into download mode, but not recovery.
Any help? Please
