Galaz A1 Tablet from Galaxy

AC Question

Hi.

Can someone help me out in how to get root Access on this tablet?
I need to install Google Play Store, Google Plus and other apps.
I can however install Google Play Store, but when I open it, it shut down at once. Google Plus, I can't install.
It says I have root Access, but when I try to enable it, it goes back to disable. It is Android 4.4.2 in this tablet.
Hope for some help, as I have allready tried every root programs I found, but none of them help.

Thank you.
