• I pulled my puck out of the drawer for the first time in a while today and connected it. I was prompted to update the firmware (I'm on a Mac, using the WebIDE on Chrome).

    It failed to update saying "Error: The state of the DFU process does not allow this operation". Subsequently it won't connect (when I connect the battery no LEDs light up).
    I can put it into bootloader mode but it won't connect to the laptop anymore (nor will it work with nrf Connect on my Android phone).

    I tried a hard reset but even after holding the button, the green LED goes off after a couple of seconds and nothing else happens.

    Does anyone have any suggestions?

  • Which application/tool did you use to perform the update?

    Could you try entering the bootloader mode again, and trying to update the firmware again?
    So apply power with the button help down and release it while the green LED is lit.

    You should then be able to re-flash the firmware to it and everything will work fine.
