Got one of these yesterday (from NI) and it's been a nightmare so far. Upon registering in Native Access I kept getting "an error occurred while processing your serial". NI support eventually registered it for me, so got past that. But now the firmware update is failing with this message "an error occurred while updating your KONTROL S MK3":
So I did just that (power-cycled the keyboard and restarted the app). And now the screen on the keyboard says "Looks like something went wrong". Restarting the keyboard 5x doesn't do anything and now the firmware update isn't working either.
I see now on the website that it says to just let it finish despite the error message, but it's a little late for that now. Seems like they ought to update the updater to show that message before others do the same.
Am I SOL here? Sure seems to be bricked. I'm a little ticked. I paid ~$100 for expedited shipping and now I've spent the past two days fighting with this thing.
EDIT: I’m on an M2 Mac and I have opened a support ticket, but was hoping someone on here might be able to help (and to warn others). Had planned my weekend around playing with this thing, so was hoping to not have to wait another couple days to hear back from them.
