I have an old Photon (0.4.3 firmware) that I just pulled back out of the box a few days ago to use with IFTTT. It was working fine with Tinker installed. I attempted to burn it for the first time with a sketch (blink) and it has been unresponsive since then. I’ve tried various things from the forums…

One issue that I had when flashing new firmware to old Photons with firmware pre-0.5.3 was that they would become unresponsive because the Photon was trying to update its firmware all the way up to 0.6.1. Check what target firmware is selected in build. If it’s anything after 0.5.3, try flashing th…

Hi @arlinjv , When you flash it, and it starts breathing / flashing magenta / purple, let it keep flashing / restarting until it gets back to breathing cyan. Depending on the speed of your internet connection, this could take 60 seconds, or a few minutes. Make sure your copy of the CLI is up-to-da…

Thanks guys! Tommy_boy - selecting firmware target 0.5.3 and flashing blink-an-led.ino I got it to indicate a successful flashing once. But the on-device led did nothing. (It was also unresponsive to the SIGNAL function on the devices tab.) Trying again I get ‘Flash unsuccessful’ and on the bottom …

@arlinjv It sounds like the blink_an_led.ino did not successfully flash to your photon. I would expect the onboard D7 LED to be blinking according to the code. Would you try to flash Tinker to the photon? You can easily do that in the iPhone/Android Particle app. Select the device and “reflash tink…

Yeah it seems that it went bad during the flashing attempt. The D7 LED not blinking was my first indication something went wrong. I just tried reflashing Tinker from the app. (The app indicates, ‘Online, non-Tinker’, btw.) After about thirty seconds the result was ‘Unable to reflash from Tinker’. I…

Have you got the most recent CLI installed? Check via particle --version. Then check the actual system version on the device in Listening Mode and particle identify Try a USB 2.0 port - USB 3.0 sometimes plays up. Try a different cable.

@arlinjv OK. I’ve never personally encountered that behavior with any of my photons. However, try this… place your photon in safe mode in case it wasn’t, and then try to reflash Tinker. Does it time out like it did before? If this reflashing does not work, then I think you’ll have to connect your …

Ok. I just updated to the 1.15.0 version of the cli. (Actually, I just installed again. Incidentally, I’m using Ubuntu and had to run using sudo - ‘sudo npm install -g particle-cli’ - I hope that’s the appropriate way to update the cli.) I’ll also try using different chords on different usb ports. …

The most recent CLI version is 1.21.0, so I’d recomment to update to that. Normally you’d use sudo npm update -g particle-cli Your error messages would point to a setup/driver problem on you computer first and only this can be ruled out I’d think it’s the device as the RGB LED codes suggest it’s …

Is my Photon bricked?

Make sure your CLI is up to date (npm install -g particle-cli) and then issue particle update and particle flash --usb tinker both while in DFU mode.

Screenshot the entire commands, and let us know the state of the LED afterwards.
