I have been running a photon for about 2 years and in general it has been working well and is running on 0.6.3. Today, it stopped responding and when I checked on it, found it flashing yellow. Strange. I figured that something odd happened, but now I am wondering if it is actually dead. Here is what I have tried so far:
- Tried to get into safe mode, when I see the magenta LED and and release the setup button, it promptly starts fast blinking yellow.
- Go to the CLI and type “particle update” which appears to complete successfully but when the Photon restarts after blinking magenta briefly it starts fast blinking yellow again.
- Manually update the Photon using the dfu-util command. Same result (e.g. successful flash followed by a brief magenta blink on boot and then back to flashing yellow.)
I am at a loss what to do next. Is this thing just dead or am I doing something wrong?
