My Motorola Ultra is running 4.4.4 and I've been holding off on upgrading to the next one since I don't want to lose any possibility of getting root. However, this morning when the notification popped up, I accidentally selected "Don't remind me, just update at this time", the time being noon tomorrow. When it tries to start the update, is there anyway I can stop it?
I've already found this hopeful answer:
I just spoke to Google directly. The Nexus 5 under settings, apps has something called Google Play services. Not store. If you uncheck the notification box in Google Play services and restart the phone the notification for the Android system updates will stop in the notification bar. Worked like a charm!
Moreover, if your devise had been rooted, you should be able to install
Disable Services and find the
Google Services Framework. Disable it.

It should work.
It looks like there's no option to disable a in-progress update. Android upgrade is done by system ui. It will keep trying to download the incremental upgrade packages. After the download is finished, it will ask you to install the upgrade. And reboot upon your confirmation. You can decide not to install upgrade when it's prompting confirmation.
