How to Root the LG L90

The LG L90 is a great choice for those who’re looking for a stylish device with the latest Android running on it. Whether you’ve already purchased the device or are looking to buy it in near future, you’d be glad to know that it has been rooted. With root on the device, you’ll have much more options to customize your device than what you have without root.

Rooting is the process of gaining administrative rights on your Android device.  Once we root our Android device, we can then make changes to it to customize it well beyond what it normally can do.

Once you have root access on your LG L90, you’ll be able to:

• Remove apps that were preinstalled by your carrier/manufacturer from your device.
• Free up storage space (because of the above benefit).
• Increase battery life (apps that might have been running constantly can be removed).
• Increase performance (after removing apps that are always running, the device will be less bogged down and run smoother).
• Update to a new version of Android (by flashing a custom recovery/ROM, see the end of this procedure for more info on that).
• Tons of other customizations when you use your new found administrative rights to flash a custom ROM (again, see the end of this procedure for more info on that).
