[Q] Stock ROM for E980? topic

Hello,

I got an LG E980 which a friend of mine brought me from the US. It was bought from AT&T I believe (it has AT&T logo and applications). Is there any stock ROM (something that doesn't come with AT&T apps)? I apologize if I posted this in the wrong area. I tried searching but I didn't really find anything, so any help would be much appreciated.

Thanks!
