We always hear about root apps that are great to install on the Samsung Galaxy S6 running Android Marshmallow and what they can do for your device. The problem is they always seem to be about what to do once you know you have root access. To save yourself some time, in the beginning, it’s a very good idea to make the root checker basic application for favorite root app to install for now so you can check whether your device is rooted or not before you go ahead and try installing other apps. The root checker basic app is free to download and install on every Android device out there, including the Samsung Galaxy S6 smartphone. Now that you know the Samsung Galaxy S6 smartphone is rooted, you know that any problems you have with installing Titanium or that SuperSU is installed and working. The SuperSU can be a tricky app to understand and just because it is on your device doesn’t necessarily mean that it is working.

The build number for the firmware that the rooting package in this guide is based on is the MMB29K.G9209KEU2DPC4 firmware. You can check from the About Phone menu on your smartphone to see if you are running that same version of not. Those who get to know that they are running the same version that the developer used to root the device. However, those who do not see the same build number do not need to worry. You do not need to be running the MMB29K.G9209KEU2DPC4 firmware. Some Samsung devices like the S6 may not boot old images, and that’s the reason why Chainfire gives us the build number to use as a guideline.

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.

Files You Need

  • Download the Samsung USB Drivers for the Windows computer you are using from here.

Some Android updates that roll out to your Samsung Galaxy S6 smartphone will bring new bootloaders with them, and they can cause the CF-Auto-Root tool to stop working temporarily. The symptoms you will find if that is happening is a device that does not boot after flashing the CF-Auto-Root tool or just a device that does not flash. You can fix these problems by submitting the new recovery image to the official CF-Auto-Root tool to the official thread on XDA-Developers that Chainfire made, and the developer will see your message and update the files. Those updates that Chainfire makes to the CF-Auto-Root tool will be automatically reflected in our guides because we link directly to his repository.

Anyone looking for some CF-Auto-Root troubleshooting tips should make sure the Samsung Galaxy S6 smartphone did get into the recovery mode that is required for the device rooting to have worked. Any Samsung Galaxy S6 smartphone that did not get into recovery mode at the end can get into the recovery mode manually instead by pressing the hardware button combination for the recovery mode after the flashing completes.

In addition to the recovery mode, the user can try installing one of the other versions of the Odin flashing tool that was not bundled with the rooting package. Chainfire gives the Odin 3.10 within the rooting bundle because it is the latest version of the flashing application anyone can install; however, there are reports of Odin not working for every device out there, and the way to solve that problem is to download one of the older versions and use it instead. You can find all versions of the Odin app from our Odin page.
