[Q] Back to 4.4 from 5. topic

Hey all,

I'm not finding any relevant results through searching.

I think, for now, I want to go back to KitKat from Lollipop.
Right now I am on the Odexed Rooted ZV8 and want to go back to 4.4.
Must I use LG Flash tool and restore or can I just flash a 4.4 rom in TWRP?

Thanks
