  • make sure to enable the USB Debugging from Developer Options.
    - if the Developer Options menu is not listed in the Settings section of your device, then you will need to enable it like this: open About Device menu, then tap seven times on Build Number.
    - visit the Developer Options menu under Settings, then enable USB Debugging.
  • if the device is running on a custom ROM, then you will see all data stored on its system partition getting wiped, which is why you might want to backup some of your most important files:
    - backup data from installed apps using Helium for Android here.
    - sync Contacts data with your default Gmail account.

    - it can be done by pressing and holding at the same time Volume Down, Home and Power buttons.
    - release the buttons when a Warning message appears, then press Volume Up to confirm that you wish to boot the tablet in Download Mode.
    - our guide for booting into Galaxy S4 Download Mode is explaining the same here - use it for extra guidance.
  6. Launch the ODIN executable on your computer.
  7. Next, use the USB data cable and connect your tablet to your computer.
    - wait for ODIN to detect the tablet.
    - if the tablet is not detected that you need to re-install the USB Drivers for your Samsung device and then repeat the entire tutorial once again.
  8. Now, click the PDA button in ODIN.
  9. Find the Android 4.4.2 XXUANA1 firmware .tar.md5 file and load it in ODIN.
    - note that you shouldn't change any other ODIN default settings.
    - make sure that the Re-Partition option is not enabled, if it is enabled you should disable it.
  10. Hit the START button and wait until the installation is complete.

If the process is successful you will see your Galaxy Tab 3 8.0 tablet booting in normal mode after several minutes. It is ok to disconnect it from your PC when the Samsung boot animation shows up.

If the installation was completed and there are no problems during the process, then you can close this article as you're done with it. If you had encountered problems then it might be best to read the notes below, too.

NOTE 1: if ODIN says that the process has failed, the app freezes, the computers restarts before the process is complete or your tablet switches off unexpectedly during installation, then you will need to repeat the entire tutorial more than once. Make sure that in case you repeat the guide, then you won't skip any steps and that you will ask for extra help in comments.

NOTE 2: If ODIN says that the process was passed, but the tablet is unable to get over the Samsung boot animation and it enters into a boot loop, then you will be forced to apply a Factory Reset that will wipe all data from the system partition forcing the device to boot in normal mode.

Here's how to factory reset your tablet:

  • power it off completely.
  • boot the tablet in Recovery Mode.
    - if you don't know how to do it, then you can follow this guide here - that is a guide for Galaxy S4 but it works with the Galaxy Tab 3 8.0, too.
  • in Recovery Mode you should select 'wipe data/ factory reset'.
  • confirm process.
  • after the Factory Reset is complete you should reboot the tablet in normal mode.

That's it, these were all the steps that you had to take. Now you can test the new firmware. For any extra help you can use the comments below.
