I’ve got a Photon that I’ve used successfully for years, but I’ve had it off-line for a while, and just now tried to bring it back on-line. I put a new (VERY simple) app on it, and have not been able to get it to behave right at all. It will never go into the breathing cyan state. Instead it cycles through every imaginable sequence of LED colors. I’ve tried a factory reset and a couple other things I’ve found on-line. I’d love it if someone could help me put it back in factory fresh mode.
