Root Reinstating production ROM

[Geoponic]

Okay, i know there are already answers to this.
But i have no idea what on earth i'm searching for.

So, for some stupid reason i want to ROOT my hero.

I've found out how, it looks very easy.
But, lets say something stops working, and i need to return it.

What do i do?

Thanks guys.

Also, does anyone know the latest MoDaCo Hero ROM?

cheers
