Hi - I've successfully used TR on my AT&T Note 3 SM-900A running 4.3. Loving it and a big thanks to all the Devs that work so hard for us ... And yes, whenever possible, I Pay for my Root apps and go Pro, etc. to help support them!
Currently having no issues except my WiFi seems to get locked up sometimes. A reboot fixes it ... I do have the Custom logo issue and I've read through all the tips and will try what I've read.
My main question: I've already got Titanium Backup freezing the Samsung Software Updates, Security Updates and Knox. With the current STAGEFRIGHT vulnerability, and any other future ones, what are the chances I can unfreeze Software Security Updates and get a fix for it without losing Root? I don't want Software Updates past 4.3 but I am hoping to get the one-off Security Only updates ... I've seem some discussions that suggest they might actually start using a more routine update process. Is there any way to side load or .apk Just the Security Updates?
