When we root the Samsung Galaxy S7 SM-G930A smartphone, we become more in control because we then have access to the root user account. The root user on Linux is not as well known as the administrator on a Microsoft Windows operating st system mainly because the Linux OS is not as popular but those two terms effectively mean the same thing. The root user can install anything they want on Linux, run any commands and also choose to uninstall that is existing on the operating system.

When it comes to smartphone manufacturers and phone carrier networks installing apps, they can only do so on the operating system. They try to hide embed them as much as possible which means installing them on the system partition. People like regular Android users who just buy a device and don’t root it cannot get access to the system partition to uninstall these apps and that is why they put them there. However, a root user can uninstall anything from the system partition because it is the root user who is the true boss of the operating system.

Here is everything anyone needs to root the Samsung Galaxy S7 smartphone with the AT&T model number when it is running on the Android 6.0.1 Marshmallow software updates by flashing the SuperSU from a computer using ADB commands:

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.

Notes:

  • You should only try this on the AT&T Samsung Galaxy S& smartphone that comes with the SM-G930A model number and the AT&T Samsung Galaxy S& Edge smartphone that comes with the SM-G935A model number. The same procedure works for both of those devices but will not work for any other devices. You may brick down the device if you try it on any other smartphone or tablet in the Samsung range.
  • The guide runs through how to root the device using ADB on a Windows operating system, but ADB is also available for Mac and Linux if you need them. The other versions for Mac and Linux require separate commands from the command prompt Windows which ids why we don’t provide it all in this one guide. You can find instructions for the other commands required online if you have one of those other operating systems.

  14. Reboot the AT&T S7 smartphone when it is done and before you try installing any of the root applications from the Google Play Store and other websites online.

In conclusion, that is how to root the Samsung Galaxy S7 SM-G930A smartphone when it is running on the Android 6.0.1 Marshmallow software updates.

The Samsung Galaxy St smartphone now has the SuperSU application installed and enabled that people can see from the app drawer. That is the same SUperSU that people normally find after installing a custom recovery and then flashing the SUperSu from the custom recovery. Moreover, it is the same kind of SuperSU that people find when flashing the CF-Auto-Root tool. That means when you start installing the root application on the Galaxy S7 phone they now give people a message on the display that asks if they would like to grant this app the root permissions required for it to run.

Anyone in need of some root application ideas can check out our list of the best root apps for Android and they should find at least a few appealing.

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.

Encryption

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.
