That is not a good start! It needs an upgrade already?
The first release only had support for flat hexa and quad, the release yesterday contained support for Y6 because I and a couple of other people had them built, ready to go, and were requesting mixer tables for them. The update was scheduled for next week but due to the requests for Y6 mixer tables they accelerated the release. The issue is that there is a specific procedure that needs to be followed when doing a firmware update and if the steps get out of order or something doesn't go right it comes back with an error that can't be cleared.
This happened to one person over on RCG and now Boris has the same issue so they haven't had time to look into it yet and come up with the fix. Hopefully it doesn't involve shipping the controller back, seems like they would be able to come up with some software that will do the job remotely, just going to take some time for the engineers to look into it and figure it out.
Not unusual for version 1 software to have some glitches, this seems to be a lot more solid than pretty much every other flight controller software I've used. The only problems I've had I caused myself, like not realizing I had misconfigured a setting on my TX that was putting the WKN into failsafe mode when I selected flight mode 2. Took me a while to figure out why it stopped responding to the controls and went into a stable hover every time I flipped that switch.
