Ok, after you restart the H9 with the HotKnob pressed and restart it again, it boots up fine though, correct? It's the updating that's giving you problems, but you can still relaunch the H9 with the previous firmware without any problems, right?
We have an alternative mechanism for updating the H9s, and I'd like to have you try that instead. I think we probably want to give you a slightly different update file than the one on the server, because I think we want to update not only your H9's OS but another component as well. I am going to need a colleague of mine to put this together for you on Monday. So, I hope you don't mind me asking you to wait until Monday, and I'll send you an email to the email account you have registered with us about that.
