Boot Loop - Sprint S5 Sport (SM-G860P) Return to Stock Lollipop from CM12

I was running MikeD63017's CM12 on my Sprint S5 Sport, and I wanted to return to stock to get the latest stagefright fix. I used ODIN 3.10 to flash G860PVPU2BOC5_G860PSPT2BOC5_G860PVPU2BOC5_HOME.tar .md5. ODIN reported Success.

I'm now in a boot loop where it gets to the Samsung screen, "Preparing your device for 1st time use..." and then reboots. I've tried re-flashing to no avail.
