Mod edit ( @harrisonhjones ): Solution: Used particle keys server to resolve the issue I set this photon up today, it worked fine until I unplugged it and replugged it in. Now its blinking cyan very fast, with intermitten red blinks. I’ve not seen this before. It will go back into setup mode, but …

So I gave that a shot, put the photon in DFU, ran particle keys doctor 56002b000b5135333532xxxxx then I get “Error - No DFU device found” Now if I put the device into discovery mode, and type particle serial list I get the device ID and firmware version. I’m not sure why it doesn’t see it in DFU …

Usually if it can’t find the DFU device it’s because you don’t have the drivers installed. What OS are you using? If windows, what does your device manager window look like?

I’m on Mac running El Cap Running node.js version 4.6 particle-cli@1.18.0 **Update - switched cables and was able to run keys doctor, but I’m still getting the flashing cyan/red lights.

Have you also executed particle keys server

That worked! Thank you @ScruffR
