I have SPH-L720 and I am trying to install the HotSpot mod for the 4.4.2 stock rom. I am using Philz Touch to install from zip and I am getting the "cannot open ..... " message. Replacing the services files method does work,but everything installed after that force closes(tried clearing cache still no luck). I would post this in the thread I saw it on but I don't have access to it yet(not enough posts) Any suggestions> BTW I also tried Auto root as well to load and it didn't work either.
The thread is here :http://forum.xda-developers.com/show....php?t=2653666
