AT&T gs3 Signal Problems

view full story

http://forum.xda-developers.com – I have searched here and google and tried about everything but I cannot find a solution. I have been having a problem with my at&t gs3 not picking up a signal, it will have bars sometimes with no data, then randomly drop all signal together. Sometimes I can get 4g after initially changing APNs, but it always drops out after a few seconds. I did get it to stay on edge for a little bit, but that also dropped out. This started right after I rooted the phone. I then installed Task's ROM, first the ICS then the JB version, to see if that would help, and it didn’t. I went through several APN se (HowTos)
