Not everyone is interested in rooting the Samsung Galaxy S7 Edge SM-G935A smartphone because not everyone will have a reason to make use of becoming the root user that so many people desire. Some people want to be the root user of the Android operating system so that they can take a complete backups, make the battery last longer, enhance gameplay and gaming graphics, strengthen the sound of the music coming from the speaker, change the way the user interface of the operating looks and several thousand other reasons. There are even root applications out there that allow people to manage their servers the websites are running on for when they are on the go. As you can read, there are very specific reasons for people wanting to run root apps, and there are probably a few out there that can change your life for the better if you only knew about them.

Here is everything you need to run through how to root the Samsung Galaxy S7 Edge smartphone with the SM-G935A model number when it is running on any of the Android 6.0.1 Marshmallow software updates using ADB to flash the SuperSU package.

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 need to have a computer that is running the Microsoft Windows operating system for this guide to work or else the files involved do not run and therefore not run the device either.
  • You can only follow this guide on the AT&T versions of the Samsung Galaxy S7 Edge smartphone that comes with the SM-G935A model number. If you follow this guide on one of the other model numbered versions of the Samsung Galaxy S7 Edge smartphones, it likely gets bricked.
  • The guide we are below is made for Windows because it shows the commands needed from the command prompt when running on a Windows operating system. However, it is important to note that Mac OS X and Linux computer users can also run ADB commands. It just required settings up with a different file than the Windows versions and also running unique commands that differ from the Windows Android Debug Bridge. Anyone prefering to use any of those can install ADB for Mac or ADB for Linux and learn the required commands.

In conclusion, that is how to root the AT&T Samsung Galaxy S7 Edge smartphone with the SM-G935A model number running on the Android 6.0.1 Marshmallow software updates. The guide results with the SuperSU application being installed and enabled on the smartphone just like it would be if you were to flash it from a custom recovery image or using the Odin flashing too land the CF-Auto-Root package. That means you see the SuperSU application from the S7 Edge’s app drawer as soon as the smartphone reboots.

Now that the Android operating system is officially rooted correctly, we have access to the root user account. The root user on Android can install and uninstall anything they want so that nothing is locked away anymore–even the apps that re installed n the system partition. That means people can start installing all of the root applications that are available from the Google Play Store and other more direct sources online. Developers can also make websites and host the apps on their websites, but make sure to be on a trusted site and an official site before installing anything. Anyone needing some sources for root apps can check out our list of the best root applications that are available to today for Android and take a pick. One of the things users can do after becoming the root user of the Android operating system is installed the Xposed Framework, which then allows for people to pick and choose which modules they would like to install. A couple of great Xposed modules for people to try are Gravity box and Xblast which collectively add many more options for the Android operating system. These options give plenty of appeal for the consumer who is usually interested in checking out things beyond stock Android.

CF-Auto-Root on XDA-Developers

Chainfire, the developer of the CF-Auto-Root tool available in this guide, has created a CF-Auto-Root tool thread on the XDA-Develoeprs website. You can use the CF-Auto-Root thread on the XDA-Developers site for requesting new root methods for devices that are not currently available.


Note that flashing a CF-Auto-Root file (regardless of the device) wipes the data if the device storage is encrypted. For everyone else, there should be no data loss when rooting with the CF-Auto-Root tool.

Samsung’s Knox security

Some smartphones and tablets in the Samsung range come with Samsung’s Knox security. The CF-Auto-Root tool trips Knox which prevents you from unrooting and using the warranty again.

Flash Counters

Any device with a target flash counter is triggered when using the CF-Auto-Root tool. Chainfire’s Triangle Away supports many devices for this problem.
