I have a vzw lg g3 running Android 5.0.1 kernel 3.4.0 software ver vs98524b. I have tried all the one click root systems for the lg devices and nothing will work. Super user installer never runs in download mode and just stays at 0%. Phone also isn't letting me downgrade back to a earlier build using lg flashtool. This is seriously driving me crazy. Can somebody please help me out here.
