ELI5: Photons have no resting state. Theoretically if a photon were held still at point (0,0,0) in a vacuum and suddenly released, what would happen?

That's not a valid question.  Photons cannot exist in a "still" state.  They're always moving relative to every other reference frame, and they do not posses a reference frame themselves.  So they cannot be stopped, even theoretically.  

Not unless you start your question with, "Assume that the laws of physics are different," in which case the answer to your question is, "Whatever the new laws of physics that you just invented that allows photons to remain stationary says will happen is what will happen."
