Geohot made the Towelroot one-click rooting application based on the Linux kernel CVE-2014-3153 which was then later patched by Android developers. The great news is that the same exploit Towelroot used remains open to anybody who is running one of the compatible versions of Android KitKat.

Anyone running Android KitKat can try rooting the G2 Mini device using the guide below and see if it works. The Towelroot application cannot brick your device, so there is nothing to fear. If it does not work on your device, you must downgrade to an earlier version of Android KitKat and the guide will start working for you.

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 browser on the G2 Mini smartphone to here during the guide:
  2. The Towelroot application roots the LG Optimus G2 Mini running Android KitKat and with the kernel version before June 3 2014. The software updates with the kernel versions that came out after June 3 will not work. Therefore, downgrade your G2 Mini to an earlier version of Android KitKat to get it to work.
  3. You do void the LG warranty when you root the G2 Mini device using the guide below. You must unroot the G2 Mini by manually flashing a stock ROM back on the device to get the warranty working again. That same stock ROM will unroot your device.

Rooting the LG Optimus G2 Mini

  1. Check that your G2 Mini has the Unknown Sources option already enabled so you can install third-party apps from outside the Google Play Store. Head to the Settings > scroll down the menu to Security > scroll down until you can see the Unknown Sources option and tap the box.
  2. Open any web browser on your Android device — you might use the Google Chrome browser that comes with your device.
  3. Enter the URL we put in the files section above to go to the Towelroot homepage.
  4. Tap your finger on the red Lambda icon that is in the middle of the homepage.
  5. Tap on the OK button, followed by Install.
  6. Now tap over the Open button and the Towelroot file will open on your device.
  7. Finish the rooting by tap over the “Make it Ra1n” button.
  8. Soon you will get the success message and a message letting you know that a reboot is not necessary.
  9. Download the SuperSU app from the Google Play Store to keep your G2 Mini device safe.

Download the root checker app to double-check the Towelroot application did in fact grant the rooting permissions to your internal system that you need to start installing the rooted applications.
