Sorry if this is a duplicate, but I can not seem to get success with blocking OTA updates. I have been hitting Install Later for the 98.18.94 update for over a month and I would like to stop as well as have the knowledge to stop future ones and take them when I want to. I am currently on 98.18.78.xt907.verizon.en.US (Razr M) and it wants me to take 98.18.94. SuperSU installed, VooDooOTA and to get rid of this OTA notification I installed Autorun Manager. I disabled SystemUpdateService$Receiver and tried to clear the cache, but I was not sure what applications cache to clear (cleared Google Paly Store, Google+ and Google Play Services). I re-booted after that. I am planning to take the OTA (when I want to and hopefully get back root with VooDoo) but wanted to make sure I know how to block OTA Updates with this one. I don't need to go too far into customization, but I want control over my OS. Any help by sharing success stories and specifics would be appreciated.
