Cant flash stock rom back onto S6

So, I have the SM-G920P. I was encrypting it when it failed. Well that sucks. Fired up Odin, set my phone into download mode, loaded the only version of the stock rom I have (5.0.2). It was running the newest version of the firmware, 5.1.1 with the stage fright fix. I'm using Odin 3.10.6 and when ever I try to flash it, Odin just says this:

How do I get it to pass?
