NOTE1:

In case the Odin app fails to complete the update, then you need to repeat the whole tutorial more than once. If you repeat installation you need to re-check the guidelines above the tutorial, and to make sure that you won’t skip any steps posted above.

NOTE2:

In case you see the PASS alert shown by Odin, but your Galaxy Tab S T705Y enters in a boot loop, then you will have to ‘factory reset’ the system partition for it to boot in normal mode.

The ‘factory reset’ steps need to be applied in case you have installed the Android 6.0.1 official update over a custom ROM, too. Here’s how to ‘factory reset’ the device:

  • power off the tablet.
  • boot it in Recovery Mode: press and hold Volume Up + Power buttons – release the buttons when the screen flickers or the Recovery options are loaded.
  • select ‘wipe data/ factory reset’.
  • confirm.
  • reboot your tablet after that.
