During 2014, a new rooting method that unlocked the system internal for many devices was released under the name of Towelroot. Nobody knows why the hacker Geohot decided to name it Towelroot, but it’s a new one-click rooting method that can root hundreds of devices so long as they are running Android KitKat.

The Towelroot exploit was a large Android security flaw and as such it made news right around the world. It forced Android to react quickly and by June 3, every new kernel version coming out in an Android update come with a patch for the known Towelroot exploit.

That means if your device is running a kernel after June 03 of 2014, your software will have patched this Towelroot exploit. The great news is you can downgrade the device to an earlier version of Android KitKat, and it will root the device just like it did when the Towelroot one-click rooting tool came out.

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 http://towelroot.com on the G Pro device when it asks you to do so during the guide.
  2. The Towelroot method is extremely effective for those of you running Android KitKat operating system. More specifically, you need to be running Android KitKat with the kernel version that was before the 3rd of June 2014 because that’s when Google developers came up with the patch. You can downgrade your stock ROM/firmware to an Android KitKat version that arrived with a kernel version before June 3 2014 and it will work. If that’s too difficult, keep downgrading until an earlier version of Android KitKat gets rooted.
  3. You are voiding the LG Optimus G Pro warranty by following this guide and rooting your device with the Towelroot tool. You can, however, unroot the G Pro and the warranty will start working again. Unrooting is the same as flashing a stock ROM manually using the Flash Tool.

Rooting the LG Optimus G Pro

  1. Make sure you have the Unknown Sources option enabled on your G Pro device by navigating to the Settings > scroll down until you see Security > tap the Unknown Sources box and tap the ‘OK‘ box.
  2. Open the main web browser you normally use to browse the internet on your G Pro device.
  3. Type the URL we gave to you in the files section above for the Towelroot website.
  4. Once that page loads, tap your finger over the red symbol in the middle we know as the Lambda.
  5. That Lambda is going to give you your Towelroot app to download. Wait for the screen to flicker a few times and then you should get a notification at the bottom of the display.
  6. Tap on the “OK” button to confirm that notification.
  7. Wait for the Towelroot download to complete and tap over the file.
  8. Choose the “Install” option.
  9. You should see a green tick with the “app installed” notification at the top left side of the screen.
  10. Tap the “Open” option on the bottom of the display.
  11. Lastly, tap over the “Make it Ra1n” button and now the magic happens.
  12. Make it Rain is code name for we are about to root your device so sit back and enjoy the show.
  13. Eventually you’ll see the “you should have root, no reboot required” message.
  14. You are official rooted on the Optimus G Pro. However, we want to make sure your experience remains safe, so please continue with the guide.
  15. Open the Google Play Store app and search for the SuperSU app by Chainfire.
  16. Install the app and if it asks you to confirm the update to the SU binary, grant that to happen.
  17. If you do not have a custom recovery installed, choose the “normal” button if it asks you how you want to update the SU binaries.
  18. The SU binary can also disable Knox if you want it to but that doesn’t apply to LG device owners, so skip that message.
  19. Now you have the root access and the SuperSU installed, your device is safe from any malware or virus. The SuperSU makes each app prompt you for the permission to the root file system. Make sure you do not give access to any apps you don’t know the name of and you will be safe.
  20. Open the Google Play Store app once last time and browse for the root checker app. Install the Basic root checker app that is free for everybody.
  21. Grant the superuser request when the root checker app asks you to do so.

Wait for the screen to change and you should get the congratulations message with some green text confirming that your device is rooted.
