I was experimenting with alternative power sources for my Photon when it suddenly stopped working. It would successfully flash sketches over USB, but when it started up it just blinked green for a second, then cyan and red. I have tried a number of various solutions including resetting Wi-Fi settings and updating keys over DFU to no avail. I fear my Photon may be fried from the voltage put through it, though my multimeter verified that it was 5V. Any help would be appreciated.
Here is what the blinking looks like right after reset:
