Hi guys, Yesterday I updated my firmware photon to 0.4.9 and today I was trying to run some app. The app that I was trying to run was the example “blink the led”. When I flashed it, my photon was blinking magenta continuously and suddenly it stopped. Now, it is not showing any signal or blinking le…

Nasty… hold the SETUP button and plug the usb in. What happens?

Make sure there’s no external circuitry attached when trying that. Also, ensure your got a proper power supply, and a good USB cable. Wouldn’t be the first time that messed things up.

Kenethlimcp… Thank you for replying. I’ve already tried this. The photon doesnt give me any sign that is working. Moors7… Thank you for replying. My photon is in the breadboard without any other component and my usb cable is the same that I use in my other photon (that is working) and the power sup…

Is the blue LED brightly lit or dimly lit? Dimly lit means the debugger port is active. You can try connecting D7, D6, D5, D4 to GND to force all debug signals to an off state (make sure no other components are connected to these pins). Then power on the Photon and try safe mode. Also try the Photo…

The blue led is dimly, so I tried to connect D4-D7 to GND. The blue led now is off, but I’m not able to enter in the safe mode. The breadboard is working fine, because I tried the same breadboard with other photon in the same position and it is working.

can you put the device into DFU mode and issue particle update from the CLI (this will take your firmware to a version of 0.4.9) and let’s see if the issue still persists from there -Corey

I’m not able to put in DFU mode. The setup and reset button are not working. Is there any other way to do it? As a reminder, the laptop is not recognizing the photon, it says the photon is disconnected.

reaching out to you now in a private message.

If you can keep this thread public that would be great as I’m having similar issue. Thanks!
