Long story... I'm not sure if anyone here can help, but I did want to post this to make sure it doesn't happen to anyone else and to see if anyone has any suggestions.
I also have an open ticket with HDM. Let's see how that goes.
I just received my machine yesterday and decided to check for a firmware update. I found one - 2.0.0.011. I was not sure if it was newer than what was on my machine, but I proceeded. My thought was it would warn me if i had a newer version or i could always get the latest. Anyway, I overwrote a newer version - 2.0.1.004. The only reason I know this is because i videoed the machine booting for some weird reason and very quickly figured out that the first number is the FW revision. I'm not sure how to get this revision and the 1st response from HDM was not all that helpful. Very generic response.
By the way, the machine seems to have lost the ability to ramp or at least pressing and holding down the up button no longer works.
When I had my Z1 that I bought in 2013 I did the software update that enabled the Z-Breathe 3 setting. It was a straight forward update, I would think that you can just go ahead and follow the instructions from HDM's web site to update to the latest software version to - it should work just fine, just as if you had a machine with the older version that you were updating.
I am assuming you are talking about the original Z1 cpap version and not the newer Auto version.......the firmware update is only for the Z1 cpap version.
Thanks under pressure and sorry I was not clear in my original post. Let me try to clear up. I do have CPAP version.
I did update the "latest" FW that was on HDM''s website and it was easy, but it was actually older than what they are using in production, so now I have less features (ramp doesn't work now). I can still adjust Z-breathe. I received a second very generic reply from HDM this morning telling me to "go to the FW update website and follow the directions." Yikes, I think I have a de-featured $1000 (I have battery as well) device now. I'm going to try and return it.
