    Install the firmware via your iPhone. It requires you downloading a zip file of the firmware you're looking for, but I had no success after a lot of trial and error until I attempted this.

    I just got my PuckJS today. I'm now seeing this issue as well.

    I'm a M1 Mac user. I tried updating the firmware from 2.15 (?) to 2.17 (?).

    I cannot hard reset it -- it does seem like I may have managed to corrupt the firmware and can no longer boot. Any help would be greatly appreciated!

    Sorry, the firmware update has failed.

    The error was: Error: The state of the DFU process does not allow this operation

    Please try again, or check out the Troubleshooting page for what to do next.

    Afterwards, I get a solid blue light. If I remove and replace the battery, I'm stuck in boatload mode again and will get the same error as above if I try to re-flash. I am unable to connect to the device in any way other than attempting to flash it
