Help with Jacky's hidden combo

Hi guys at VFDC forum, I am new here.
I got a question for you.

I still play Virtua Fighter 4 and the oldest chapters of the series, but I can't remember a combo for Jacky in VF3 and VF4.

It's the combo that appear in VF3tb intro, that beging with side hook turn /forums/images/%%GRAEMLIN_URL%%/b.gif/forums/images/%%GRAEMLIN_URL%%/b.gif/forums/images/%%GRAEMLIN_URL%%/p.gif then, somersault kick /forums/images/%%GRAEMLIN_URL%%/ub.gif/forums/images/%%GRAEMLIN_URL%%/k.gif to go behind the enemy and ends with the lightning storm kick /forums/images/%%GRAEMLIN_URL%%/db.gif/forums/images/%%GRAEMLIN_URL%%/p.gif+/forums/images/%%GRAEMLIN_URL%%/k.gif/forums/images/%%GRAEMLIN_URL%%/k.gif/forums/images/%%GRAEMLIN_URL%%/k.gif/forums/images/%%GRAEMLIN_URL%%/k.gif/forums/images/%%GRAEMLIN_URL%%/k.gif

The problem is when backturned, I don't know how to do the somersault, but I can do only a simple turn kick /forums/images/%%GRAEMLIN_URL%%/k.gif

What should I do?

 

Maybe just /forums/images/%%GRAEMLIN_URL%%/u.gif /forums/images/%%GRAEMLIN_URL%%/k.gif?
