I had GPS issues, but occurred while updating PA rom from the various versions before.
I fixed it while screwing up my downgrade from 4.2 -> 4.1 because of the file folder architecture and I was unable to nandroid restore. Ended up wiping completely and ODIN back to stock and starting all over. Now back where I left off @ 2.54 STABLE and GPS works again.
Anyways you guys successfully restore nandroid from 4.2 to 4.1??
