No idea, this is a perfect example why rooting is not always the best thing to do to a phone.

The locked-down carrier-controlled with a deathgrip AT&T SM-G900A. I'm stuck with it myself.

I think your best hope is to take it to AT&T and hope they can do a complete wipe and factory restore. Of course then you'll be on 5.1.1 with Touchwiz until August 2016 or so.
