I want to root my LG G Vista, hardware Rev. 1.0, Droid version 5.1.1, kernel 3.4.0+, software version VS880PP2. Has several intermittent problems, and I Really wanna figure out what is wrong with it
There are some good apps to Root most of the Phones for example Kingroot is good https://kingroot.net/ install and run it and your phone should be rooted
There are several ways to root your device.
The quickest and easiest way is to use the one-click root method, provided by several apps and developers.
Hopefully you'll find that one of these are compatible with your device! I really like KingRoot and find that it's most reliable.
TowelRoot and Framaroot also work well, but I find that they support less devices than KingRoot.
All you have to do is install the app, launch the app and tap on "root" or something of the sort.
