samsung - Phone still stuck in a bootloop after flashing official firmware with Odin!

I successfully flashed a stock ROM on my Galaxy Note 4 using Odin 3.13.1 but, unfortunatelly, the bootloop is not gone.

Device info:

• SM-N910C


• unrooted


• Android 6.0.1 Marshmallow

Bootloop sequence: Samsung boot screen —> Android is starting... Optimising Apps 2 of 2. —> Android is starting... Starting apps. —> LOOP

What are my options to restore my personal data from now on?
