So far (you may skip this part):
I have managed to successfully install Spirit Rom with full functionality, by copying my old build.prop into the system directory, and restoring my previous apn settings using the apnsbu. I forget why I left this rom, but I did. Everything I try has some problem! I then proceeded to try just CM11, by itself, and had 3g difficulties. Then, using Kushman's sprint MIUI, (Ntelos shares sprint towers) things seemed to work right, but it remapped my recent app key to menu... (perhaps I can map it back?) and the volume was not controlled by my physical volume buttons.
Now my favorite rom so far: Mokee Rom It's fast and visually pleasing, but I have wi-fi and phone difficulties.
After imposing my APN settings, I can reproduce these effects:
(1) Before replacing build.prop, the wi-fi works and can be enabled or disabled as I need. Also, 3g works very well at nice speeds, but it says "Verizon Wireless" underneath the 3g indicator bars. However, I cannot make calls. If I attempt to do so, the 3g data stops working, turns orange, and no longer says "3g". If I do this, then no data can be transmitted or received.
(2) After Replacing build.prop with the "good original" copy (which sometimes fixes similar problems in other custom roms) the wi-fi becomes stuck in a constant state of "turning wi-fi on..." but never turns on. 3g still works, but, as in part (1), it will break if I try to make a call.'' Also, in this case it says "Sprint" instead of "Verizon Wireless"
Does any one have advice, or perhaps some build.prop settings to modify? Or maybe there's a different file that would help. Again, my phone is the SM G900R7. Has someone else with this phone had luck customizing it?
