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.

Notes:

  • 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.

How to Root Samsung Galaxy Tab S2 SM-T810 on Android 6.0.2 Lollipop Using CF-Auto-Root

  1. Log into the Windows computer using the administrators account so the flashing tool can run. (Those who only have one account created on the Windows computer will be the administrator of the operating system by default).
  2. Unlock the Developer Options menu on the Samsung Galaxy Tab S2 tablet so you can enter that menu and then turn on the option available for the USB Debugging Mode.
  3. Enable the USB Debugging Mode from the Developer Options menu so that when you connect the tablet to the computer and the flashing tool the Android software allows for some developments.
  4. Extract the CF-Auto-Root tool to the desktop of the computer and the rooting file and the Odin flashing file will both pop out into the desktop.
  5. Install the Samsung USB Drivers on the computer so that the tablet can be detected by the Odin flashing application when you open it.
  6. Boot the Samsung Galaxy Tab S2 tablet into the download mode and then connect it to the computer with the USB cable that is usually used for charging the battery.
  7. Double-click on the Odin .exe file that is on the desktop and the flashing tool opens.
  8. Check that you get a blue or yellow color showing up from the ID: COM port in Odin which is there to let you know that the Samsung USB Drivers you installed earlier and working.
  9. Click the AP button and browse the desktop for the tar.md4 rooting file that has the CF-Auto-Root in the file name.
  10. Do not make any changes to the default settings that you get from the Odin flashing application or else it might not work, or you might accidentally wipe some data.
  11. Click the Start button from the Odin flashing tool’s user interface and then the rooting begins.
  12. Have a look at the screen of the Samsung Galaxy Tab S2 tablet and it gives you many details about what is happening with this new systemless root version of the CF-AUto-Root tool, including some important notices. The important notes go into some detail about the first reboot can take minutes and that it might boot loop a few times, and you are not to worry about it because it is now a regular part of the new rooting process.
  13. Keep watching the text running down the display on the tablet eventually, says it is restoring the stock recovery, cleaning up and then reboots in ten seconds time.
  14. Look back up at the PC display now and check that Odin shows a green box and has a pass message inside that box which is letting you know the rooting is complete, and you may unplug from the computer now.

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.

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.
