HI everyone. I think i accidentally installed the wrong firmware on my att sgh-i337 GS4. I'm not positive but that's what I think will happen. Appears that it is not rooted as I ODIN keeps failing. Also wireless does not work so I cannot get any internet connection to work. I just want to get back to ANYTHING usable. KIES does not see my device. Please help me get back to anything. I was trying to help a friend with his phone and ended up in this state so I want to get it back to him working in anyway. I've done a few of these and never had this much trouble. Help please. Thanks.
