Rooting the Samsung Galaxy Tab S2 SM-T810 is going to make you the guy in charge of the Android operating system for the first time. It is now you who is going to have the chance to install anything you want and uninstall anything you desire also. Being handed the key like that comes with responsibility which is why devices do not come with the root user permissions out of the box. There is a chance you can uninstall the wrong thing, and it makes the Android operating system unstable. There is also the chance that you install the wrong thing like malware, and it can roam through the software and jump between apps.

Once you know all the ins and outs of the Android operating system and are confident that you know how to avoid trouble, the upside of being the root user starts coming into play. The upside includes being able to install any of the apps from the Google Play Store. These apps might not sound like much excitement on the surface but there are apps out there that can do some incredible things to make the battery last longer, overclock the hardware so that it gives better performance than the default settings, help enhance the music you love to listen to so it sounds better than ever before and even restore old photos that you deleted a really long time ago. One root application that most people should be able to make use of is the Titanium Backup app. As long as you know what not to uninstall with the Titanium Backup app, it can help people create backups of data better than anything else out there available from the Google Play Store. It’s unique ability to be able to see and read other apps (thanks to the root access) allows it to save data that you just cannot do using other apps like Helium.

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.


  • When we choose to root a smartphone or tablet from the Samsung range with the CF-Auto-Root tool by Chainfire, we are always tripping Knox security on any device that comes with Knox security. Note all Samsung devices do. It is usually reserved for the better and more modern devices in Samsung’s range. You can read more about Samsung Knox, so you understand what you are choosing to trip. Tripping Samsung’s Knox security means that the security still works, but when you unroot the device, Samsung will now that you have rooted it, and therefore the warranty never works again. That is different from the old times when the warranty would start working again once people unrooted the device.
  • The CF-Auto-Root tool that is made in this guide is only going to work for the Samsung Galaxy Tab S2 tablet that comes with the SM-T810 model number. Not only that but it can brick the device if you flash it on the wrong one, so take a few seconds to check out the model number of your device just to double check. You can find the model number of the Samsung Galaxy Tab S2 tablet by tapping on the Menu > Settings > About Device > Model Number.
  • There may be some more Android software updates that roll out over the air for the Samsung Galaxy Tab S2 SM-T810 tablet that is based on the Android 6.0.2 Marshmallow software updates. It is possible that some of those also bring new bootloaders with them. The chances of this are slim because the new bootloader usually only come with a newer version of Android such as the jump up from Android 6.0.1 Marshmallow to Android 6.1 Marshmallow. Nevertheless, it is possible and if a new bootloader does come it can temporarily break the CF-Auto-Root tool from working until Chainfire updates the file. For him to do that he relies on people leaving the new recovery image found inside the new firmware that is creating the problem at the official CF-Auto-Root tool thread that is made for the rooting tool over at the XDA-Developers web forum. He sees the message people leave and then apply the changes that are required to get it working again. Those changes that Chainfire makes are always going to be automatically updated in our guides because we always link directly to his pages.

In conclusion, that is how to root the Samsung Galaxy Tab S2 SM-T810 tablet when it is running on the Android 6.0.1 Marshmallow software updates by using the systemless root version of the CF-Auto-Root tool. There isn’t much difference with the systemless root version and the older version which is why you might not have even heard about it. It creates a cleaner rooting tool because it no longer needs to modify the system partition. One of the fundamental differences with the systemless root version of the rooting tool by Chainfire is that applying a hard reset will now fully unroot the tablet whereas before you needed to flash the stock ROM or do it from within the SuperSU app.

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.
