Hi
I am trying to add a new SSID to the exiting ones on my photon.
For that I need to moving to other location in range of the new SSID.
In doing that, when I power up the Photon it start to quick flash blinking green, which I understand it is looking for WiFi, and If I continuous observing the blinking, what follows is SOS aan after that again with green blinking.
I try to set up the Listening mode to add the new SSID and push the setup button 3 sec or more but nothing happens, I cannot get blue blink. Quick flash green blinking is continuing.
This seems to be a double post from the other thread, hence I’ll move the other post with answers to this thread.
Just to be explicit: Double posting is frowned upon.

Try engaging Safe Mode first, before you try to enter Listening Mode.
You won’t need to wait for the device to go into flashing magenta, just start SM and then press/hold SETUP again.
Sorry about that, it will not happen again.
Thank you.
I followed your steps. I was unable to to put the device in listening mode.
Just it was fast blinking green going to red flashes.
I decided to use particle doctor through CLI.
I follow the same procedure three time with no success.
Photon remain in WiFi off after doctor ends.
This is what CLI report:
" The Doctor will operate on your Photon connected over USB
You’ll be asked to put your device in DFU mode several times to reset different settings.
Updating system firmware
Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue

> This process should take about 50 seconds. Here it goes!
! System firmware update successfully completed!
> Your device should now restart automatically.
Flashing the Device Doctor app
This app allows changing more settings on your device
Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.

!!! I was unable to detect any devices in DFU mode…
> Your device will blink yellow when in DFU mode.
> If your device is not blinking yellow, please:
1) Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously.
2) Release only the RESET/RST button while continuing to hold the MODE/SETUP button.
3) Release the MODE/SETUP button once the device begins to blink yellow.

Thank you for your help
You can also just clear the credentials by holding SETUP button for 10+ seconds till the RGB LED starts rapid flashing blue.
After that the device should immediately enter Listening Mode on power-up (if your code isn’t using a non-AUTOMATIC SYSTEM_MODE).
If it doesn’t try Safe Mode again.
BTW, it seems you haven’t installed the required DFU drivers (check in Device Manager).
Have you installed CLI via the Windows Installer or npm.
If the latter, remove CLI via npm uninstall -g particle-cli and reinstall with the Installer, this should also install the DFU drivers.
If not, you may need to install them manually via zadig
