If ODIN displays the FAIL alert, then you will be forced to repeat the entire tutorial more than once.

If you repeat installation you need to make sure that your device meets all requirements, and that you won't be skipping any steps listed above.


In case the ODIN tool shows the PASS message, but your smartphone enters in a boot loop or it gets stuck at the boot animation screen, then you will be forced to Factory Reset the phone for it to boot in normal mode.

The Factory Reset process wipes clean system partition, while it leaves the internal storage untouched. Factory Resetting the smartphone will make it boot in normal mode with the stock Android 6.0.1 update.

The Factory Reset steps need to be applied by those that have installed the Android 6.0.1 update over a custom ROM, too.

Here's how to factory reset the device:

  • power off the device.
  • boot it in Recovery Mode.
    - it can be load Recovery Mode by pressing and holding Volume Up + Home + Power.
  • select 'wipe data/ factory reset' option.
  • confirm the process.
  • reboot phone in normal mode and you're done with this post.

These were all the steps that you had to take in order to complete the update. If you need any extra help you can tell us in comments.
