I have a US AT&T Note 3, I have followed this guide (http://xdaforums.com/showthread.php?t=1856632), however on the AT&T Note 3 there's not FotaUpdate.apk. Is there another name for that file on an AT&T phone? I heard AT&T will come out with the KitKat update soon, I do not want to be automatically updated when that happens. Please help. Thanks.
