Stuck in Flash Mode after Root

[zeldarocks2]

So I rooted my new Droid Maxx, everything seemed to go smoothly, then, all of the sudden, I find that my phone has turned off; I restore my phone via Safestrap and discover that it will only boot into the Invalid Flash Mode. Is there any way to restore completely and get it running again?

EDIT: I used DroidRAZR Utility to restore to 6.12.173; is that all there is to it? Have I now been unrooted as well?

Do you see the Superuser app in the app drawer?
