The Samsung Galaxy Tab S2 tablet does not come with root permissions out of the box. However, each Android operating system always has root user permissions available; they have just decided to lock them up so neither you or I can use them. The only way we can use them is if we follow a guide that lets us root the device, such as the way here with the Samsung Galaxy Tab S2 tablet running on the Android 6.0.1 Marshmallow update.
There are heaps of ways we can root the Android operating system. The way you will ultimately use depends on your needs and what is available for your device. Those of you who are wanting to flash a custom ROM that does not already come with root access wants to install a custom recovery and then flash a version of the SuperSU from the custom recovery image. Note that installing the SuperSU from the custom recovery image like TWRP Recovery is different from just downloading and installing the SuperSU from the Google Play Store. Those who just install the SuperSU application from the Google Play Store will not find the tablet rooted, but those who install the SuperSU from the custom recovery partition will locate the recovery also works its magic and ends up rooting the device at the same time. It can all be a bit confusing because when you install SuperSU from the custom recovery and then reboot back into the normal mode, you download the apps and the SuperSU gives a message asking whether or not you want to grant the app root access. That is slightly misleading because you are already using the device as a root user. What is happening is the SuperSU automatically blocks everything and double checks that you do in fact want to grant it root access to the internal system. It does this because it is the only form of protection you have. There is no anti-virus installed in the SuperSU app that is going to set off alarms when it is malware asking you for root access. It solely relies on your intelligence to know what to allow through and what to block. While that may sound complicated, know that as long as you download apps that you know are trusted and only grant root access to the app names that you know you installed, then you should remain safe.
The CF-Auto-Root tool is made uniquely for each device and the software it is running. Chainfire has based the CF-Auto-Root tool found in this guide on the MMB29K.T710XXU2CPD9 firmware build number which is part of the Android 6.0.1 Marshmallow updates that rolled out to at least one area in the world for the Samsung Galaxy Tab S2 8.0 SM-T710 tablet. It does not matter if your tablet is running the same firmware build number or another version. Chainfire just gives that information for you to use as guidelines. He does not provide that information because you need to be running the same firmware. You can run any firmware that is based on the Android 6.0.1 Marshmallow software update for the Samsung Galaxy Tab S2 8.0 SM-T710 tablet, and it should work just the same.

There might be some Android updates that Samsung and your phone carrier networks roll out for the Samsung Galaxy Tab S2 tablet that is still based on Android 6.0.1 Marshmallow that brings new bootloaders with them. These issues do not usually happen because new bootloaders are found in the larger updates that update to newer versions of Android, so as long as you are running Android 6.0.1, the file in this guide should be work for you. However, if your file does need updating because your Galaxy Tab S2 does not boot or does not flash, you need to submit the new recovery image files found in the new firmware builds to the official CF-Auto-Root thread made over at the XDA-Developer website. That thread has been created by Chainfire, who is the man behind the CF-Auto-Root tool. Chanfire will see your messages and then apply the required updates to the rooting file on his end. Those changes are automatically reflected in our guides as soon as he makes the changes because we link back to the original CF-Auto-Root tool repository.

You should also see an “added” message appearing in the Odin app user interface on the computer confirming that is the case. (Those who do not see any color need to install the Samsung USB Drivers, or log into an administrator account because one of those two things is not working).

- Check you get more text indicating that it is doing the SuperSU Installer, followed by the Boot Image Patcher.
- Read the important message that is now on the display that says that you can expect the Tab S2 to reboot a few times over the next few minutes, and it might even loop; these are normal and not problems. Do not be alarmed and do not interrupt the rooting process.

In conclusion, that is how to root the Samsung Galaxy Tab S2 8.0 SM-T710 when it is running on the Android 6.0.1 Marshmallow software updates by using another version of the CF-Auto-Root tool by Chainfire. The tablet now reboots back into the normal mode as it says on the screen ad you are then able to install the root checker application from the Google Play Store. The root checker app checks the root status, and it does all of that free or charge. However, there is a paid version of the root checker app that can do even more such as give you the pleasure of having BusyBox installed.
Once you have checked the root status of the Samsung Galaxy Tab S2 tablet, you can see all the things you can do with the root Android and then decide in what direction you would like to head. You might be interested in installing the root applications that require root access to run, or you might want to do something else entirely. Some of the things you can do from this point include installing a custom recovery, installing a custom ROM, remove the system apps some people refer to as bloatware, increase the hardware performance, and improve the battery life. Many of those things you can do by installing applications that require root access to the Samsung Galaxy Tab S2’s internal system to run.
Furthermore, you can try installing another version of Samsung’s Odin application if you need to use a version that is different than the Odin 3.10 that Chainfire packages in with the rooting tool. There are times when people try using the Odin 3.10, and it does not flash, so they try another version of Odin 3.09, and it does flash. That might be your solution if you are willing to give it at least a go.
Moreover, sometimes the rooting process is known not to get into the recovery mode which is an important part if getting the SuperSU installed and enabled correctly. You do not have to give up if you are finding that problem; just boot the Samsung Galaxy Tab S2 into the recovery mode as soon as your tablet reboot back into the normal mode after flashing the rooting tool.
