Permanently turn off System Auto Update

[Yguideslou]

Just wanted to update and let you know that your suggestion worked! I purchased the disabler from the website directly and no more reminders have popped up since! Thanks again.

You're most welcome.

Enjoy being able to disable all unnecessary bloatware

Today, an xda member suggested flashing a previous modem, in order to trick the phone into thinking it was already updated, due to the missmatch between modem and rest of the firmware. I've never heard of this before.
