[Q] GT-P5210 stuck on boot screen topic

Hello there, I just attempted to root my tablet following this tutorial http://androidxda.com/root-samsung-g...-10-1-gt-p5210

And after Odin showed a success the tablet it stuck on black boot screen that says samsung galaxy tab3

I have rooted androids so many times in the last years, first time something went wrong

So how do we get it back working?
