The Android operating system that runs on the Samsung smartphones and tablets is renowned for being the most popular operating system in the world and extremely customizable. There is a paradox there already: the Android operating system comes to you locked and yet it is known as the world most customizable OS that comes as stock on a mobile device.

The world of rooting the Android operating system is a complex one, but the idea behind it is simple: if you need to run certain apps that need full write permissions in the root directory, then you first need to “root” the device before that can happen. Rooting Android is about taking control of the operating system much the same way that a system administrator would take control of the UNIX operating systems on a computer.

The UNIX operating systems have been around for a long time as a multi-user system. Whenever you have a system that is not intended as a personal computer for one, you will find times where it makes sense to have a master account and other accounts with lesser permissions. For example, a system administrator who knows everything about the operating system often has full master control over an operating system at a business and the employees who use the computers but are not necessarily experts in computers use them with lesser permissions. Moreover, should the people using the computers with lesser permissions need additional permissions they can report that to the system administrator. The key here is not allowing people to use the computer with full privileges if they don’t know what they are doing because the full system access can mean they accidentally delete things that could not be deleted for the system to run correctly.

You could argue a similar reason with the likes of the Android operating system that is running on the Samsung devices. It too can create a problem if people who don’t know what they are doing are given full system access and thus it doesn’t make sense to make everyone in control of the root user account by default. Instead, if you know what root access is on Android and you know you want it and have the ability to use it, then you can follow a guide that helps get that done.


  • Chainfire had the MMB29K.T715N0KOU2BPE8 firmware build number on the Samsung Galaxy Tab S2 SM-T715N0 device when the version of the CF-Auto-Root tool that can be found in this guide was developed. He always let’s us know the firmware he had running on reach device he creates a rooting tool for; however, by him letting us know that information he is not suggesting we need to be running on that same firmware build number. It is just there so you can use it as an indicator if there ever becomes a time when that becomes relevant information to know.
  • You need a computer that runs on Windows if you are to use this guide that involves flashing the rooting file from the Odin flashing application on a computer because the Odin flashing application does not run unless it is on a Windows operating system.
  • You need top have the Samsung Galaxy Tab S2 tablet that comes with the SM-T715N0 model number if you are going to use this guide because the rooting files are only made for one particular model number each when using the CF-Auto-Root tool and flashing the wrong rooting file often results in that device getting bricked until you flash the right stock ROM on the device again.
  • Leave a message that includes the recovery image from the firmware your device is running on the CF-Auto-Root tool thread on XDA-Developers if you flash the rooting file, but your tablet does not boot up after the flashing has occurred because it often means that Chainfire needs to update the rooting file. He cannot refresh the file unless he has the recovery image file from the firmware. If you require downloading the firmware so you can come up with the recovery image file, you can get it from the Sam Mobile website.

How to Root Samsung Galaxy Tab S2 SM-T715N0 on Android 6.0.1 Marshmallow Using CF-Auto-Root

  1. Start off by logging into the computer with the administrators account so you can use the Odin flashing tool with the required administrative permissions.
  2. Unlock the Developer Options menu on the Samsung Galaxy Tab S2 SM-T715N0 tablet so you can use the menu that becomes available for developers to use.
  3. Turn on the USB Debugging Mode from the Samsung Galaxy Tab S2 SM-T715N0 tablet and the Android software then allows you to start making the necessary changes to it for the rooting to work.
  4. Install the Samsung USB Drivers on the computer if they are not already installed so the Odin flashing tool can identify the device that is trying to connect to it.
  5. Extract the rooting file to the Downloads folder on the computer and then run the Odin flashing tool application that is available from the Downloads folder after extraction.
  6. Boot the Samsung Galaxy Tab S2 SM-T715N0 tablet into the Download Mode and connect it to the computer with the USB cable.
  7. Look for the added message to dhow up in Odin now and the ID: COM port to light up with a yellow or blue color, so you know that the Samsung USB Drivers you installed are working and the device is ready to have the rooting file flashed.
  8. Do not make any changes that you could make from the Odin Options tab.
  9. Click on the AP button that is on the Odin app and then navigate to the Downloads folder—which is where you extracted the rooting file moments ago—and then click on the MD5 rooting file to get it to upload to the Odin.
  10. Click on the Start button that Odin has, and the rooting of the Samsung Galaxy Tab S2 then begins.
  11. Have a read of all of the information that is rolling down the tablet’s display that Chainfire has programmed to keep you informed about what is happening and then wait until the screen says the tablet is rebooting in ten seconds.
  12. Check the Odin user interface for a message that says it has passed just after the device reboots.

That is what is required to root Samsung Galaxy Tab S2 SM-T715N0 tablets when they are running on the Android 6.0.1 Marshmallow software updates by flashing the systemless root versions of the CF-Auto-Root tool. The systemless root versions are available from Android 6.0 Marshmallow and Chainfire will likely try his best to keep it going that way because it allows his FlashFire application to benefit from it. The app that he has created let’s people try to maintain the root access on the device—even after updating to newer versions of Android. It isn’t reliable for all devices, and things can go wrong, but you can use it if you want to try it out and see how you go. The FlashFire application is available from the rooting file page that is accessible in the guide when you are directed to click the link for downloading the file.

At the end of the day, it doesn’t matter what version of the CF-Auto-Root tool that you used because they all mean you can run the same amount of root apps. Most of the root applications are available from the Google Play Store. If you don’t find the root apps you wanted to test out from Google Play, then you will likely find the others from the XDA-Developers web forum. Any of the rest you will find from the developer website that is always available from a Google search.

Alternatively, if you need to do some research on what the root applications are that you want to try, you can check out our article that goes into great details about most of the Android root apps and then remembers the names for the next time you are looking to find them online.

You can also tackle the root application learning challenge by reading about what can be done with root access and then find the root apps that do those things instead of you prefer.
