Photon 5.2 - Blinking Cyan - not found in DFU mode [SOLVED]

I have a photon that is blinking cyan and every 10 or 15 seconds I see the LED cycle through the other colors and then it goes right back to blinking cyan. The last thing I did (and it went through without any errors) was run the particle_firmware_manager-v0.5.2b-windows updater on it.

Also when I put into DFU mode it can not be found by particle update or the DFU util.

Any ideas what might be wrong?

Cloud keys were either missing or corrupt. I did the following to resolve the issue.

Installed DFU drivers
particle keys new
particle update
particle serial wifi
