Thanks for reporting this, and sorry for the issues you are having.
Are you able to quit/reopen Emote and connect to the H9000 again? If so, you could attempt the update via Emote again.
If not, you can try rebooting the H9000 and attempting the update again. It is likely that the update has not been sent to the H9000 from Emote if the H9000 isn’t displaying any update progress, so rebooting it shouldn’t cause any issues.
Let me know what happens.
