K22 Not Communicating

I was brought a K22FN256LH12 board that I just got back from production, and when I plug the J-Link Pro in it instantly turns the LED red. I am also unable to communicate using the JLink commander. Below are images of the errors I keep getting. It says the protection bit is enabled it seems, and therefore I allow it to do a mass erase, but then it still cannot communicate with the board. Any thoughts or is this board shot?
