Towelroot is a free android app that gives you full superuser access to make manipulations as you see fit. It has reduced the complexity of rooting a device. The success rate of this program in Android gadgets is more than that of other apps.
SuperSU is a term that geeks and anyone who has sought for information on root access must be familiar anywhere in the world. It grants access management rights to all apps that are installed on your LG G3.
Downloading and installing the USB drivers will establish a connection with your PC without requiring a PC Suite. In the absence of this, you need a PC suite to make it possible for a seamless connection to be established.
Generally, a personal computer is required to run a full-proof rooting process. But you can perform it in your LG G3 easily without any computer. All you need is this specific tool that has been developed for this process.
