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.

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.
