Moved to Sprint S4 Q&A as the folks in there can probably get you what you need in short order. (Mine still on pre-Knox and will probably never update.)
Update: I see the exact same thing posted in two 3 other threads. Not sure if intentional or not but going to ask to have all but the one with longest discussion (including this one) closed. No need to spam the forum with this request.
Happy to provide further information if needed. Thanks!
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
