There are a couple of ways people usually root Samsung smartphones which include flashing a custom recovery image and then installing a stable version of the SuperSU application from the recovery partition. The other way people enjoy is flashing Chainfire’s CF-Auto-Root package using the Odin flashing application. With the Samsung Galaxy S7 smartphone being new, those options that take time are not available just yet. The Exynos processor version of the Samsung Galaxy S& Edge smartphone has TWRP Recovery available, and that serves as a platform for those devices owners, but everyone else needs to keep waiting. There is a few recent exception to the waiting list which includes the Sprint version of the Samsung Galaxy S7 smartphone and also the AT&T version of the S7 and the S7 Edge smartphone.
The way in which we get root access on the Samsung Galaxy S7 with the Sprint model number is different from the AT&T, but both of them have some things in common. The main difference with this Sprint version is that it requires a Disabler Pro application downloaded first and there is no SuperSU involved, unlike the other models. If this guide does not work then, we suggest creating the super folder and then flashing the SuperSU using ADB like it shows in the how to root Samsung Galaxy S7 SM-G930A on Android 6.0.1 Marshmallow software updates article.
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.
- Rooting the Sprint Samsung Galaxy S7 smartphone using this guide is going to void the warranty. Moreover, any smartphone that comes with Knox security is going to get tripped. A phone that comes with Samsung’s Knox security–which is usually the most popular phones and tablets–means that when you unroot the device the warranty does not come back again. Once Knox is tripped Samsung can see what yo have done and therefore have no interest in allowing it to be submitted under warranty.
- Download the Package Disabler Pro application that is available on the Google Play Store.
- Download the engineer boot.img file.

In conclusion, that is everything people need to root the Sprint Samsung Galaxy S7 smartphone when it is running on the Android 6.0.1 Marshmallow updates. The method is posted to the XDA-Developers forum, and if it does not work, we suggest reading over the first few paragraphs and clicking through to the AT&T version which shows how to flash the SuperSU package after the steps in this guide.
As soon as the Sprint Samsung Galaxy S6 phone reboots back into the normal mode, you should find that it installs and run the root applications that are available from the Google Play Store. Anyone who does not know any off by heart can check out our list of 60 best root apps for Android and take a look at some that we think are the highlight apps most people should try. The list includes some of the traditional options like Titanium Backup, Xposed Framework, ROM Manager, Smart Booster, FolderMount and Disk Digger Undelete.
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.
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.
