- Select the Install button from the Recovery menu and then follow the guidelines to browse the SD card and select the SuperSU zip file to install.
- Swipe the bottom of the display where it says you need to swipe to install it if you are using TWRP or follow the guidelines to complete the installation of the SuperSU if you are using another custom recovery.

In conclusion, that is how to root LG K10 smartphones running on the Android 5.1.1 Lollipop software updates by flashing a suitable version of Chainfire’s SuperSU from a custom recovery partition. The custom recovery is what makes it all possible by giving us a modified recovery to get the SuperSU not only installed but enabled correctly too. Now your device reboots back into the normal mode, and you can see the SuperSU app available from the app drawer. There is no need to change the settings from within the SuperSU app although you are welcome to check them out if you wish by tapping on the app just like you would any other. The root apps are waiting for you to install them and runs effectively immediately.
