Disabled SuperUser Binary - now phone stuck on logo in boot

So I have a rooted S6 Edge, and I unchecked a box in SuperSU Settings, something along the lines of 'enable SU binary' or something. Now when I try to start the phone after a reboot, it's stuck on the carrier logo.

Is there any way I can ADB into my phone and re-enable the su binary? Or is there any fix I can do short of having to factory reset and reinstall everything?
