Samsung Galaxy Tab A stuck at logo [migrated]

My Samsung Galaxy Tab A stuck at the logo screen.

Frozen Samsung Galaxy Tab A
All I could find on internet so far were advices to push power button together with Volume up.
But it doesn’t react for me.
Push and hold power button also doesn’t react.
The only combination where I see a reaction is Power + Volume down after 7 seconds screen is black for a couple of seconds after that the logo screen just comes back and here we are again.

What could be the (any) next step?
