The LG G3 AT&T variant has a new method for installing Team Win’s TWRP Recovery. The TWRP Recovery is main people’s favorite custom recovery because it’s quicker to use than ClockworkMod recovery.

The menu’s found inside are also short, sweet and easy to understand. If you want to gain root access for running applications that want access to the root file system and flash a custom recovery image so you can begin installing custom ROMs on your smartphone, check after the drop on how to do that.

This is how you can root the LG G3 smartphone that has the model number that was given to AT&T subscribers and get Team Win’s custom recovery image flashed as well.

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.


  • You should turn on the handset and head to the Settings, followed by the About Device menu and check the model number matches with D850. You cannot use the guide on a different model number.


  • You are still voiding the warranty by following this guide using the Auto-Rec application. Flashing the stock version of Android once again after this should take away the root access and restore the warranty.
  • Download and install the LG USB Drivers.
  • You must enable the Unknown Sources option from the LG G3 by turning it on and navigating over to the Settings > Security and then enabling the Unknown Sources from the list.
  • Enable the USB Debugging Mode: Settings > About Device > tap the build number seven times. Go back to the Settings > Developer Options > check the box for enabling the USB Debugging Mode.


1. Download the LG_One_Click_Root_v1.3.msi  to the desktop of the Windows PC.

2. Extract the package and run the rooting tool on the computer. You need to double click over the  LG Root Script.bat file to do that

3. Now just follow the set of on-screen instructions and you’re done.

4. Now that you have root access it’s time to flash the TWRP Recovery.

5. Unplug the G3 from the computer.

6. Download the Auto rec app direct from Google Play here directly to the smartphone.

7. Once it’s finished downloading, tap on the new app icon available in the app drawer.

8. Wait a few moments as it backs up your data automatically.

9. Click the TWRP Recovery option when it’s available.

You’ll now have a custom recovery image installed and access to the root file system as well. The root access means you can start installing applications that need access to the root file system, one of which is the ROM manager application which can help you install custom ROMs. Assuming there are other ROM files out there in existence, you can also flash them directly from the custom recovery image by using the option from the recovery’s main menu.
