Double white blink


I am having an issue with my Photon. I was having an issue where it would continuously blink white. I flashed the updated firmware via dfu-util. Now when I plug it in it goes through a constant cycle of double white blinks. I can get it into dfu mode but I cannot then do a factory reset. It always goes back to the double white blinks. I cannot get it into setup mode or safe mode. Please help. Thanks

Was your Photon working normally before this happened?

Yes, it was working fine then suddenly started booting up into a blinking white status. I figured I had turned it off in the middle of a firmware update or something to that effect so I reflashed it as described here
