I'm having the same problem with a photon that I ordered a while back. The device is connected to wifi, I can see it in build, breathes cyan, I can ping it, I can signal it and see the led rotate through the colours.
I've tried putting it into safe mode but the video doesn't seem to indicate what colour the led should be breathing when it's in safe mode (is it supposed to stay breathing magenta?), so I suspect that I might not actually have succeeded in doing so. I hold down setup, press reset, wait for the flashing magenta and then release the setup button. It always comes back to breathing cyan.
Any help would be appreciated.
Cheers,
Dave
