How to downgrade Hudl 2 from Android Lollipop 5.1 to KitKat?

I do not like the new update. Very slow, laggy and my Snapchat does not work anymore

I am regretting upgrading it too and the only way to downgrade it is to wipe the whole system and install a old factory image.
And that is what I am going to do but it does cancel the warranty though.
So no, there are no easy way to downgrade it.
