So today I found my Photon completely non-functional. The only thing showing is a steady blue light on the user LED off to the side. The main multi-color LED between the two buttons is off. I tried power-cycling, a different USB cable, etc. but every time I power it up, the small blue LED lights up and nothing else. I tried pressing various combinations of both buttons but nothing happens. Also, when I plug it into my laptop, it’s not making the usual “USB device connected” sound.
How do I get this thing going again?
