ok ive been looking looking and looking for how to unlock my s4 for sprint. and its starting to become annoying, ive found a couple vids about kitkac. and those were unsucseful. i have a version 4.4.2 build and base are NAE. L720..08 model-SPH-L720. all im trying to do is unlock it so i can get free wifi teather. im currently using a hacked version of foxfi. and works fine for mounted computers. but cant get the wifi tether to work. if you could send me links on how to get this all done. id be highly apperciated. thank you very much for the help!!!!
