How to root Samsung Galaxy Tab S2 SM-T810 on Android 5.1.1 Lollipop [Guide]

Galaxy-Tab-S2-3These are the guidelines to root Samsung Galaxy Tab S2 on Android 5.1.1 Lollipop. You can check your software version from the About Device menu. Scroll down the Settings menu until you find the About Device menu to take a look. The Android 5.1.1 Lollipop update is the major Lollipop update available for this device.

We recommend not updating your software version until you know a new rooting method is available for that software if you would like to keep root access in the future. Google patch many of the exploits in future software updates which makes some rooting guides unusable until a new guide is made available.


  • The following guide is made for the Samsung Galaxy Tab S2 device. More specifically, you must have the Tab S2 with the model number SM-T810 only. You can check what your model number is by heading to the Menu > Settings > About Device and checking the model number.


  • Download the universal ADB drivers from our USB drivers and ADB drivers download page. Try installing the Samsung USB Drivers if the ADB driver doesn’t work for your device. You can find both options available from the same page.
  • You can only follow this guide to root Samsung Galaxy Tab S2 on a Windows computer. All other operating systems will not load the flashing tool and thus make the guide ineffective.
  • Make sure you have the Developer Options enabled by tapping over the build number seven times from the About Device menu. It will let you know when it’s unlocked.
  • Check the USB Debugging Mode option is enabled from the Developer Options menu by heading to the Settings > Developer Options and searching for the USB Debugging box.


  1. Download the custom kernel from this link.
  2. Download the CF-Root package from the S2 SM-T810 from this link.
  3. Next, click this link to download the Odin flashing tool.
  4. Shift all three files over to the desktop of your computer.
  5. Right-click over the files and choose the “extract here” option from the menu.
  6. Run the Odin flashing tool by double-click over that executable file.
  7. Reboot your Samsung Galaxy Tab S2 in download mode.
  8. Connect the Tab S2 to the computer using the USB cable.
  9. Wait until you see the ID: COM port change colors so you know the drivers are working.
  10. Click the AP/PDA button and upload the custom kernel.
  11. Click the Start button and flash that custom kernel.
  12. Click the AP/PDA button on your Odin user-interface and browse the desktop for the executable Cf-Auto-Root file.
  13. Leave the default settings as they already are in the Odin user-interface.
  14. Double-check the re-partition box is left empty because you do not want to re-partition your drive.
  15. Click the Start button and wait until you see a pass message from the Odin user-interface.

The Samsung Galaxy Tab S2 should automatically reboot since the Auto reboot option was left checked in the default settings. However if your device does not automatically reboot, you should reboot it manually before doing anything else.

Once the device is rebooted, head to your app drawer and check if you can see the SuperSU app. This app usually is installed by default on your device after rooting with the CF-Root tool. If you cannot see it there, head to the Google Play Store and download the SuperSU app by Chainfire.

    Hi Ben,

    Yeah, I do have a guide coming for the 710 on 5.1.1. I was planning to post them all at once but I got really busy. I should have it out today.

    SM-T810 is specified. Is there something that can be done to adapt these instructions for the Samsung Galaxy Tab S2 SM-T710? Thanks.

    Hi Todd,

    I recommend adding your blogging platform in the search term you are aiming for, or visiting the official help forums associated with your website platform.

    For example, if you are using Joomla, check out the Joomla forums or include Joomla in the search term.

    Where do I find the help forums? I have a question that I can’t seem to find the answer too. Thanks!!! I know this probably isn’t the right place, but I can’t find it in dottech like I used to and all my search terms are failing. HELP PLEASE!! I am looking to have my English Language Learners (I teach
    English as a Second Language students) write in a blog to give them a
    real world audience and to help them practice English writing
    conventions, etc. Is there a way to set up authors so that their posts
    have to get administrator (me) approval before appearing? I don’t want
    anything that could identify them or give out personal info to appear, so I need this setting to be sure it doesn’t. Thanks!!
