[Q] oh oh ! Have I screwed the pooch ? HELP topic

Rooted with iroot,
Downloaded the V8 ROM, SuperSu, Kernel for N801X, WiFi Fix for N801X and Remove phone stuff for N801x
- Installed rashr from Google play store and granted root when asked.
- from rashr installed the latest twrp recovery image.

Here is where I fouled up. I held down the power and volume down keys until
I got a warning about installing non official stuff. The I held down the volume up key
(which I think was the wrong thing to do) Now I am sitting with an Android logo and a
warning "Downloading do not turn off target!!" What's happening? How do I fix this? Can I fix this?

HELP.
