I have an LG Optimus F3 from Boost Mobile, I've been trying to root it. When I did have a computer I tried motochopper and it didn't work. I no longer have a computer. I've tried safer out and towel root and neither of those worked either. 4.1.2 android version 3.4.0 kernel JZO54K build & LS720ZV7.1401502974 software.
