Did you resolve your stalled upgrade issue? What was the solution? Has anyone else experienced issues. And… How many can provide feedback on a successful upgrade??
To answer my own question… The upgrade to 1.9 on my Qu24 went well. I had the flickering screen on startup, but one shutdown/power down sequence cleared that.
Now all devices, including Android, are at the same level and auto update is disabled. I will not be burned by that again. Newbie mistake.
If I was to ask for one thing, it would be a better indication of progress either via the screen or the channel LEDs.
