Hey @YeOldeCrown, thanks for your post! Let's see if I can find a fix for you.
Software updates are, by default, set at 3am to avoid any disruption to your normal business hours. If you need to adjust your nightly reboot time, head to ≡ More > Settings > Hardware > General from the navigation bar at the bottom of your screen. Tap Nightly Reboot and select the time that works best for your business.
Note: This adjustment will not take effect on the next nightly reboot, but instead the one after that.
As for the terminals getting stuck, have you tried doing a factory reset on the terminals affected by this issue? You mentioned you were still able to switch them off during the update. To hard factory reset your Terminal, hold the button down for about 10-20 seconds until the screen goes black, then try switching on your Terminal again and starting the software update again.
Hope this helps, let me know if the issue persists. I'd be happy to take another look into it.
