Default Won't Boot

I was on stock 4.4 rooted with Franco Kernel. I tried using Wugfresh to return back to stock, after trying I just get Boot Failed when I boot or try recovery. I'm not the best with Android so any help would be great. I have tried downloading stock 4.4 Rom from Google and flashing via Wugfresh but still the same. I'm worried I can't use again now.
