Root
You can use Stump Root 1.2.0 to root the LG G3 for the VS98510B software release. If you have VS98511C (which Verizon has been shipping with the phone since late 2014) then this version of Stumproot will fail with the error message:
device is patched, sorry
Use the LG Flash Tool to install the VS98510B software revision, rolling it back, then run Stumproot.
