LG Optimus F3 4g lte Root (goulash93)

Hey all,

So I want to root my LG Optimus F3 4g let (Virgin Mobile) to an android 4.3 or later OS. Is there a way to do that/does this root even exist for the phone?

I've tried using the process in this link right here:

The problem I get with this is that when I plug in my phone to the computer, the computer never displays the pop up that says "Allow USB debugging," which the original post says should pop up. Instead, the regular "sync with windows media player" malarky pops us.

Any tips?

Just won a Samsung Gear Live and I'd love to test this sucker out with ma phone! Eternally grateful
