This is a new method of blocking software updates on a rooted Fire TV or Fire TV Stick. It involves setting a custom software version number in the device’s build.prop configuration file. Rbox came up with this idea and asked me to test if it works. The main advantage to this update blocking method is that it can be implemented from within TWRP custom recovery before the device boots. That means, if you factory reset (i.e., wipe data partition) a Fire TV, you can ensure the device does not update during the initial setup process. Prior to this method, you had to rely on external router or OpenDNS update blocking methods when going through the Fire TV initial setup process after factory resetting. Now you can block updates internally before starting the initial setup process. If you have a rooted device and are blocking updates using the “pm disable …” method (method 1 in my blocking guide), it’s a good idea to also follow this guide to have an additional update blocking method in place.
