I’ve got a possessed Photon. My student put some firmware on it that displays interesting colors with the RGB LED, but we can’t replace it with anything else. I put it into dfu-util mode and then used
particle flash --usb photon_firmware_1567703188561.bin
It says Flash success! and I see the RGB go white, flashing green, and then … back to my student’s firmware.
I don’t know if this is related, but I tried doing particle update (figuring I’d update to the latest deviceOS), and get
! An error occurred while attempting to update the system firmware of your device:
File too short for DFU suffix
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
dfu-util: Error during download get_status
