Towelroot is a rooting method made people by Android KitKat software update. The man behind the rooting method is the XDA recognized developer Geohot, who is the same guy to first jailbreak the iPhone all those years ago. Just like the iPhone that is nearly impossible to jailbreak these days, the Towelroot application no longer works for the new software updates either.

Since the LG Optimus G3 is an older device that doesn’t run the latest software update like Android 6.0 Marshmallow, many people can still root the device using the Towelroot method. Furthermore, anyone can downgrade the Optimus G3 at any time and start running the Android KitKat update and get root access to the G3 device.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.

Files You Need

  1. Point your web browser to the http://towelroot.com website when it tells you to do so during the guide.
  2. You are voiding the warranty of your LG Optimus G3 device by following this guide.
  3. The following guide will root your G3 using the Towelroot application so long as your device is running Android KitKat with the kernel version before June 3 2014. After that date, every software update came with a patch in the kernel and the Towelroot exploit is blocked. You can anytime downgrade your firmware to a compatible version or Android KitKat and root the device.

Rooting the LG Optimus G3

  1. Make sure you have the Unknown Sources option enabled on your device so you can install third-party apps like the Towelroot app on your device. Get that done by navigating to the Settings > scroll until you reach Security > scroll down until you reach the Unknown Sources option and check the box for that option.
  2. Point your web browser on the G3 smartphone to the Towelroot website we gave in the files section above.
  3. Tap your finger on the red Lambda icon and it will download the file to your device.
  4. Follow the prompts to install the Towelroot application on your device.
  5. You should see the “Make it Ra1n” button in the end.
  6. Click the button to make it rain, which means to get root access on your device.
  7. Soon you will be greeted with the pass message and you’re done.
  8. Your LG G3 smartphone now has root access to the root file system and you can leave if you want. However, we strongly recommend you continue following the guide for safety.
  9. Head to the Google Play Store on your device and install the SuperSU application. The SuperSU app will keep your device safe. Now it acts as a gatekeeper and will not let any malware through unless you give that app permission. That’s why you must read what you are granting permission if it asks for your permission in the future.
  10. Lastly, install the root checker app on your device to make sure your device does have the root access it needs before installing the root-requiring apps from the Google Play Store.

In conclusion, you are now ready to start installing any apps that require root permission from the Google Play Store and other third-party sources online.
