My unleashed appears to be paired but does not trigger and does not update firmware.
I've tried to reset to factory, unpair, reboot, remove and pluc again... Nothing works, any clue?

Camera is Nikon z6.

It start happening when I attempted to update the firmware.

Here a screen recording.

Hi and sorry for the issues with the update!

I see that your serial number is below 4500, so we almost definitely have a fix for you. You will not believe this but the following trick will almost definitely help: Put the Unleashed in the freezer for 10-20 minutes, then plug it into the camera and try the update again, while it’s still as cold as possible.
We took a long time trying to find the cause of this problem. We found the problem and fixed it, but the fix comes in Firmware A, so if there’s ever a problem during the update of Firmware A, the fix will no longer work either.. The trick with the freezer has a scientific explanation too - now that we know the underlying cause.

Please try a few times - we've had cases where it worked only after the 4th or 5th attempt, see these threads:

I hope it helps!

I've done over 30 attempts without success leaving it in the freezer for 20-60min. Almost giving up I forgot it in the freezer for few days and today I tried again and it worked. It is now updated.

Thanks for the help.

Haha,
wow, that was unexpected, but I'm glad you got it to work:

The good news: there is a fix in our firmware for the problem for which the freezer is a workaround. So you won't need to do this again, unless firmware update A fails mid-way at some point, then it can happen again.

Enjoy your cool new updated Unleashed ;-)
