[LG Optimus G Pro] ULTRAM4X:
that one is what I installed, and I cant get 3g working... all the rest is awesome, good battery life and no lag. Really recommend it.

I think it´s some build.prop related, because I flashed all modems that I found and I can´t got it workin.

here is my build.prop and a screenshot, to see if anyone can help me please. really appreciate your help because i need data for my work!
