Show Method 2 Guide This method uses your router’s parental controls to block the domains that the Fire TV accesses when downloading updates.Even if you used method 1 on a rooted device or method 2 on an unrooted device, it’s still a good idea to also use this method.The added advantage of this method is that it can be done within TWRP custom recovery.That means, you can have updates blocked on the device itself BEFORE completing the initial setup process.This method disables the service running on the Fire TV which checks for updates. If your Fire TV is rooted, this is the recommended method, but it’s always a good idea to also use Method 3 to block updates via your router in case the update service gets re-enabled, which happens after a factory reset.Show Method 1 Guide This method requires Fire OS 5.0.0 thru 220.127.116.11 to be installed on your Fire TV or Fire TV Stick to work.

The first category, highest priority, contains only the worst of the worst threats, and will offer protection against the major bot and malware infections that we are seeing globally in near real time.
As the categories increase in rank, the threats they stop decrease in severity so that by category 5 most of the rules are related to adware or riskware infections.
