Go back to 4.1.1?

Hi guys, I'm pretty new to rooting and all that kind of stuff so I messed up a bit. Anyways, I rooted my AT&T Galaxy s3 (was on 4.1.1 before root) and got AOKP for 4.2.2. I had a few problems and tried restoring to 4.1.1 but I guess I messed up on my Nandroid backup somehow and my Titanium backup is no longer there. Is there any way I can go back to 4.1.1? Even if I have to get rid of my root I'm fine, as long as I can go back to 4.1.1. Also, Kies does not recognize my 4.2.2 device so if I go back to 4.1.1 it will recognize my phone, right? I lost all of my texts and would love to ge them all back (I backed them up on Kies). Thanks guys! I really appreciate it :)
