If you look at KinRoot's site (https://www.kingoapp.com/root-tutorials/how-to-root-lg.htm ), you'll notice that it says that you have to keep trying (because it tries a different rooting method each time) or you have to use the PC version. (And not all rooting programs have root methods for all phones - each phone, on each version of Android, has to ber rooted differently.)
