[G3 Q&A, Help & Troubleshooting] thjubeck:
You can get service on stock if you use my guide but I can't get the com.android.phone app to work. Otherwise text and internet are working on stock sprint already. You don't have to modify the modem for it to work only modify the build.prop. I'm working on getting the rest to work at the moment.

below is the contents of the file you referenced but these are not the settings that the phone uses.
