Rooting any Android device is not for people who are not experienced Android users. Those of you who do not know much about a virus or malware should not root any Android device, since the rooting of the file system can make it easier for malware to get on your device if you download it.

Those of you who know how to easily spot malware and browse the web safely can root the LG Optimus Extreme L40G and install better apps on the device.

If you haven’t ever rooted a device before and want to learn more, you can install the Root for Android — All About application and it will tell you all about rooting. You do not need root access to install this app so you can check it out before deciding to follow the guide below if you prefer.

Files You Need

  1. Download the LG L40G root exploit from this page.
