The Samsung Galaxy Tab S2 tablets, can get rooted a couple of ways. If there is ever a custom recovery image available for your device, then you can flash it and then flash the version of the SuperSU that is working for the tablet. That is the method that people who want to install a custom recovery usually follow because it ends up being slightly the quicker of the two ways to end up with both a custom recovery and the device rooted.

Nevertheless, there is another way we can root the Samsung Galaxy Tab S2 thanks to Chainfire and his CF-Auto-Root one-click rooting tool. Many people prefer using CF-Auto-Root because it is quick and easy. It is also the preferred method for anyone who does not want a custom recovery installed on the Samsung Galaxy Tab S2 tablet.

In case you are not sure, a custom recovery is what you need if you want to start installing custom ROMs and change the version of Android. You do not need root access to install a custom ROM. Some people just like to do that for something extra. The act of rooting the Android operating system is what you need to do to be able to install all of the apps that are out there being developed that require access to the root file system before they can run. We see these applications all over the Google Play Store because Google does not mind that they are there, it just doesn’t want to give everyone root access automatically by default. Google prefers giving people a device that comes with the operating system locked and then it is up to you if you want to root it and unlock it so the apps can be installed. The kind of apps that I am talking about include popular titles like Titanium Backup, Greenify, ROM manager, Xposed, Dumpster, Game Killer,

Details We Should Know

  • Chainfire was running the LRX22G.T815YDVU2AOK1 firmware build number on his personal Samsung Galaxy Tab S2 tablet with the SM-T815Y model number when he came up with the rooting file that is available in this guide. Nobody else necessarily needs to be running on that same firmware build number that he was running when he created the tool. The following rooting file found in this guide should work for all Android 5.0.2 Lollipop software updates that have rolled out for the SM-T815Y model number.
  • You must have the Samsung Galaxy Tab S2 9.7 with the SM-T815Y model number when you use this guide. Flashing the rooting file on the wrong number can result in the device getting bricked.
  • You must have a computer that is running a version of the Windows operating system to use this guide. The CF-Auto-Root tool is an Odin-based one-click rooting tool that can only be flashed with Odin. The Odin app only works on a Windows computer. Anyone who cannot find a Windows computer can try settings up a Windows virtual machine.
  • If you are finding the CF-Auto-Root tool is not flashing, or it flashed, but the device now does not boot up again, it could be because a new bootloader is present in the firmware you are running. These times are very rare because they are usually only around in new versions of Android, and if you followed the guide on Android 5.0.2 Lollipop, then there are no new versions of Android to worry about here. Nonetheless, if you are facing the problem, you can leave the new recovery image found in the firmware on the CF-Auto-Root tool thread made over at the XDA-Developer’s website for Chainfire to see.

In conclusion, that is how to root the Samsung Galaxy Tab S2 9.7 SM-T815Y tablet when it is running on the Android 5.0.2 Lollipop software updates. The rooting method makes use of Chainfire’s CF-Auto-Root tool, and it is the most traditional method that works on the Android 5.0.2 Lollipop updates. That means you can unroot from the SuperSU app or by flashing a stock ROM on the device. It does not unroot when you take a factory reset like the systemless root versions would.
