My particle Electron board was sealed up inside the box that came with the solar kit and it WAS working. Today I decided to try to write some code for it and I was not able to upload the code. I could see inside the box that the RGB led was not lit up, but the blue D7 led was on solid. I took it out of the box and attempted to flash it over USB. When I plug it in with the USB cable, the red led starts to blink rapidly. I am not able to get it into DFU mode or do anything at all really.
Here is a video of it connected to the USB port on my computer. I try pressing all the buttons, both buttons at the same time, etc. and I get no change in behavior.
