The official Android 6.0.1 OTA Update is now live for all the LTE models of the Samsung Galaxy Tab A 8.0 devices.

If you own one of these tablets and you don't want to wait until Samsung pushes the new firmware in your region, then you should be checking the info listed in this post.

The new update is being done by Samsung in stages, but not all users are going to receive it in the following, which is why a 3rd party app like ODIN can be used to flash the new update manually. In order to be sure that you will complete the new update at your first attempt you should read the guidelines below:

  • use this post only for the Samsung Galaxy Tab A 8.0-inch model.
    - check your tablet's model under Settings> About Device section and make sure that the SM - T355 version is listed there.
  • don't try to update any other different Android devices with the files that you will find in this post.
  • download the Samsung USB Drivers from here and install them on your computer.
    - the usb drivers will allow your device to be detected by the PC.
  • in order to complete the new firmware update manually you can use the ODIN app.
    - Odin is a great tool designed by advanced Android users looking to flash firmware updates by themselves.
    - for ODIN to open on your PC you need to install those usb drivers above.
  • enable USB Debugging option from your tablet's Developer Options menu, too.
    - the Developer Options might be hidden which is why you should enable them by going to Settings> About Device and tapping 7 times on the Build Number text.
    - return to Settings, scroll down and you should now find the Developer Options menu.
    - open Developer Options and find USB Debugging option to enable it.
  • if you are planning on installing Android 6.0.1 update over rooted firmware, then you need to know that root access will not survive the new update.
    - any custom Recovery that you might have installed is going to be replaced with a stock Recovery, too.
  • you can flash Android 6.0.1 official firmware with ODIN over custom ROMs even, but you will have to 'factory reset' the tablet in order to make it boot in normal mode.
    - the 'factory reset' removes the old custom ROM by wiping the system partition, but it won't delete any data from the internal storage of your Galaxy TAB A.
    - factory resetting the tablet is needed if you plan to install the update over custom ROM firmware and the steps can be found at the end of this post.
  • if your tablet runs 100% stock Android firmware, then you can continue to the next part of this post and start the update process right now.
  • check the whole post first and don't skip any steps.
  • this guide is destined to be used by advanced users, we cannot be blamed in case you brick the tablet nor in case you lose any data in the process.
  • check the battery charge level of your phone and make sure that there is at least 50% charge left before the tablet powers off completely.

If you don't want to manually install the update with ODIN, then you can wait until Samsung pushes the update over-the-air in your region. You can check for new firmware updates by going to Settings> About Device> Update Now section of your tablet.

How to install Android 6.0.1 Marshmallow update for Samsung Galaxy Tab A 8.0 T355:

  1. Download the Android 6.0.1 T355XXU1BPE2 firmware archive from here.
  2. Extract the contents from the archive and save the obtained files on your computer.
    - you should find a T355XXU1BPE2 tar.md5 firmware file.
    - don't extract the tar.md5 archive.
  3. Download Odin 3.10.7 from here.
    - unzip the files.
  4. Power off the tablet.
  5. Now boot it in Download Mode.
    - press and hold Volume Down + Power until Download Mode loads.
    - if a 'warning' screen loads you should press Volume Up to confirm.
  6. Open Odin exe on your computer.
  7. Connect your tablet to your PC via usb cable.
    - wait for ODIN to detect the tablet.
    - if no device is detected you have to reinstall the Samsung usb drivers once more.
  8. Go back to ODIN and open the Options tab. Make sure that the 'Re-Partition' option is disabled.
    - don't edit other default Odin settings.
  9. Now, in ODIN click the AP button and locate the T355XXU1BPE2 tar.md5 firmware update file.
    Load the file in ODIN.
  10. Hit START to begin the Android 6.0.1 firmware installation.
    - don't press any buttons until all the new files are done installing.
  11. When the update is done you can see the phone rebooting and the PASS alert shown by Odin tool.
    - the reboot will take at least 10 minutes to complete.
  12. Unplug the tablet from PC after the update is done and use your default login info in order to regain control over your device once again.

These were all the steps that you had to take in order to complete the update.

If the FAIL alert is displayed by Odin, or the update process gets stuck at some point, then you will need to try and repeat the installation once more. Make sure not to skip any steps and that your phone meets all requirements listed above.

NOTE:

If the PASS alert is shown by ODIN, but your phone is unable to go past the boot animation screen or it enters in a boot loop, then you have to 'factory reset' the device.

The 'factory reset' steps below should be applied by those that have installed the Android 6.0.1 update over custom ROMs, too, as that will force the tablet to boot in normal mode. Here's how to 'factory reset' the device:

  • power off the tablet.
  • boot it in Recovery Mode.
    - Volume UP + Power buttons at the same time.
  • select 'wipe data/ factory reset'.
  • confirm process.
  • reboot your phone in normal mode.
