Samsung has started to update all the 2015 variants of the 9.7 Galaxy Tab S2 tablets. If you are looking to manually install the update, then this is the guide that you should follow.

Android 6.0.1 Marshmallow OTA Update has been issued in Germany first, but it should soon reach other regions across the globe, too. However, if you're eager to test Marshmallow on your Galaxy Tab S2 9.7 Wi-Fi, then you can do flash the firmware update manually using the ODIN app.

Before starting the updating process you should read the following guidelines:

  • use the tutorial only with the 2015 Wi-Fi Samsung Galaxy Tab S2 9.7-inch model.
    - the version of this tablet should be SM - T810 and it can be verified under Settings> About Device section.
  • don't try to flash the files that you will find in this post on any different Galaxy Tab S2 models other that the model listed above.
  • download Samsung USB drivers here and install them on your computer.
    - it will help your PC detect the tablet via Odin app.
  • Odin is a small tool designed for Samsung users to use in case they need to update their devices manually.
    - for ODIN to open on your computer you need for those USB drivers to be installed and for any Samsung official app to be disabled.
    - also, Odin requires you to enable USB Debugging option on your tablet from its Developer Options menu.
  • if you can't find Developer Options you will need to go to Settings> About Device and tap 7 times on the Build Number section.
    - return to Settings, scroll down and there you should find the Developer Options, open it and find USB Debugging to enable it, too.
  • you can install the new update over rooted firmware, but you will lose root access.
    - any custom Recovery will be replaced with a stock Recovery image.
  • if you are running a custom ROM on your Galaxy Tab S2 Wi-Fi you can install the update, but you need to factory reset the tablet after the update is done.
    - the 'factory reset' steps are listed at the end of the article and you should apply them only if you have installed the update over a custom ROM, or in case your tablet doesn't boot in normal mode after more than 20 minutes after installation is done.
    - factory resetting the device is going to remove the old custom ROM, but it won't delete any data from internal storage.
  • in case your device is sporting 100% stock Android, then you can get to the installation instructions right now, as you won't risk losing any data files and the update should complete without problems.
  • install the Android 6.0.1 Update manually only if you are an advanced user.
    - don't blame us in case you brick the tablet nor in case you lose any important data in the process.
  • read the entire post and do not skip any steps.
  • check the battery charge of your device, make sure that there is at least 50% charge left before starting the update.

How to install Android 6.0.1 Marshmallow OTA Update manually for 2015 Galaxy Tab S2 Wi-Fi:

Remember that this guide works only with the SM - T810 models.

  1. Download the T810XXU2CPD9 Marshmallow archive updating file from here.
  2. When the download is done you need to extract the archived files and save the contents on your PC.
    - you should obtain the T810XXU2CPD9 tar.md5 firmware update file.
    - don't extract the tar.md5 archive, leave the file on your computer.
  3. Download Odin3 v3.10.7 zip from here.
    - extract the zip contents and save them on your PC.
  4. Power off the tablet.
  5. Boot it in Download Mode.
    - it can be done by holding Power + Volume Down buttons.
    - release the buttons when the 'downloading' or a warning screen loads, then press Volume Up once to confirm Download Mode boot.
  6. Launch the Odin exe on your PC.
  7. Connect the tablet to PC via usb cable.
    - wait for Odin to detect the device.
    - if the tablet is not detected you need to reinstall the Samsung USB drivers.
  8. Go to Odin, open the "options" tab and make sure that 're-partition' is disabled.
    - don't edit other default Odin settings.
  9. Next, click the AP button in Odin in order to browse your PC for the updating file.
  10. Find and load T810XXU2CPD9 tar.md5 file in ODIN.
  11. Hit START button to kickstart the Android 6.0.1 updating process.
    - don't press anything until the update is done.
  12. When the Marshmallow firmware has finished installing on your Galaxy Tab S2 Wi-Fi you will see the tablet rebooting and the PASS alert shown by ODIN.
    - the first boot process of this new official ROM is going to take a while before it loads all the new files.
  13. When the 'optimizing apps' screen loads you will know that the update is done and you can unplug the device from PC.
  14. Use your usual login info in order to regain control over your device.

If you've encountered any problems during installation you should check the extra info listed in this post.


In case you're notified by ODIN that the installation has failed, then you will need to try and repeat the whole guide more than once.

If you decide to repeat installation you should make sure that your 2015 Galaxy Tab S2 Wi-FI device meets all requirements listed above the tutorial and that you won't be skipping any steps.


If PASS is shown by ODIN, then the update was applied with success. In case your tablet doesn't go past boot animation screen after 20 minutes or it enters in a boot loop with no sign of the "optimizing apps" screen loading up, then you will be forced to 'factory reset' the tablet.

The 'factory reset' steps should be applied in case you've installed the update over a custom ROM, too. If you have installed official firmware over custom ROM, then your tablet won't boot in normal mode.

Here's how to factory reset your Galaxy TAB S2:

  • power off the tablet.
  • boot it in Recovery Mode.
    - press and hold Volume Up + Power until the screen flickers and the Recovery Mode options are displayed by the tablet.
  • select the 'wipe data/ factory reset' option.
  • confirm.
  • reboot tablet in normal mode and you are done.
