Update Samsung Galaxy Tab A 9.7 LTE to Android 7.1.1 Nougat


The Samsung Galaxy Tab A 9.7 LTE is being rolled out over-the-air for all the users across Europe. Check the instructions listed in this post in order to learn how to manually update your tablet in case you don’t want to wait until the new firmware becomes available in your region.

The Android 7.1.1 Nougat official update is released all over the world for the T555 LTE unlocked models of the Galaxy Tab A 9.7 devices. These updates are usually released in stages, as not all users are going to get the new files at the same time.

This tutorial is great for those that are running a custom ROM, as you can easily flash an official Android ROM over modified operating systems using the same ODIN app. Before starting the flashing process you need to check the following guidelines:

  • use this tutorial only with the Samsung Galaxy Tab A 9.7 LTE models.
    – the model number of your tablet  has to be the SM – T555.
    – don’t use the tutorial for other different devices.
  • download the Samsung USB Drivers from here.
    – install the drivers on your PC, as otherwise ODIN won’t be able to detect the device.
  • for the ODIN app to work with your computer and tablet you will have to install the above usb drivers, and to enable USB Debugging under your tablet’s Developer Options menu.
  • Developer Options might be hidden, go to Settings> About device> Software Info, here tap seven times on the Build Number text.
    – return to Settings, open Developer Options, find USB Debugging and enable it.
  • you can install the new Android 7.1.1 update over rooted firmware, but you should know that root access won’t survive the update process.
    – any custom Recovery you might have flashed will be replaced with stock Recovery.
  • you can install the new official update over a custom ROM, too, but you need to know that an extra Factory Reset process has to be applied after the install is done.
    – the Factory Reset will wipe clean the data from system partition.
    – no data will be lost from internal storage.
    – also, note that the Factory Reset steps are listed at the end of the tutorial.
  • in case your table is running 100% stock Android firmware, then you won’t be losing any files in the process and you can begin the update process right away.
  • read the whole post and do not skip any steps.
  • this guide has to be applied by advanced users, we cannot be blamed in case you brick the tablet nor in case you lose any data files in the process.
  • check battery power, there has to be at least 50% charge left before the device powers off completely.

In case you do not want to install the new firmware manually, then you should wait until Samsung pushes the new firmware update over-the-air in your region.

You can also check for new firmware updates by going to Settings> Software Update> Download Updates Manually menu. If a new update is ready for you to install, then you should confirm the process and your device will take care of the rest of the process.

How to install Android 7.1.1 Update for Galaxy Tab A LTE 9.7 T555:

  1. Download the new firmware update file from here.
    Note that you will need to make an account to be able to download the file.
  2. When the download is done you have to extract the archived contents and save them on your PC.
    You will obtain 5 different update files. Save them all on your computer, and don’t unzip their contents.
  3. Download Odin 3.12.3 zip from here.
    – when the download is done you can unzip the files.
  4. Power off the tablet.
  5. Boot it in Download Mode: press and hold Volume Down+ Power buttons.
    – when the ‘warning’ message loads you need to press Volume Up to confirm Download Mode boot.
  6. Launch Odin exe on your PC.
  7. Connect the tablet to PC via usb cable.
    – wait for ODIN to add the device.
    – if the Galaxy Tab A T555 is not added you need to reinstall the Samsung USB drivers.
  8. Go back to ODIN main menu as you now have to load the firmware update files.
  9. Click BL and load the tar.md5 file that start with “BL” in its name.
    Click AP and load the tar.md5 file with “AP” listed on its name.
    Click CP and load the tar.md5 file with “CP” listed on its filename.
    Click CSC and load the tar.md5 file with “HOME_CSC” in its title. Don’t load the tar.md5 file with only “CSC” in its name, as that will completely wipe the entire device contents.
  10. When you’re ready to begin the firmware update process you simply need to click the START button.
    – when the flashing process is done installing you will see the PASS alert shown by the ODIN app.
  11. Unplug the tablet from PC and wait for it to reboot in normal mode with Android 7.1.1 new OS.

These were the steps that you had to take in order to complete the new official update for your tablet.

If you see the FAIL alert is displayed in ODIN, then you have to repeat the whole tutorial more than once. If you repeat installation you need to make sure that your tablet meets all requirements and that you won’t be skipping any steps.

NOTE:

If the PASS alert is shown by ODIN, but the tablet enters in a boot loop, or it gets stuck at the boot animation screen for more than 20 minutes, then you will have to factory reset the device.

The Factory Reset process wipes clean the system partition, and that is why the steps below have to be applied by those that have installed the new official update over a custom ROM, too.

Here’s how to Factory Reset the tablet from Recovery Mode:

  • power off the device.
  • boot it in Recovery Mode: press and hold Volume Up + Power buttons.
  • select ‘wipe data/ factory reset’.
  • confirm process.
  • reboot device in normal mode.
