At this point I'm willing to try the modem even if it breaks WiFi. Knox has become more of a hassle for me and the fact that I'm a noob at using custom Roms doesn't help. The new modem really ruined this phone. I no longer connect to EVDO or 1x data if I'm fringe whereas before it had no issues. Even my old Evo3D didn't have a problem establishing data connections and that phone had terrible rf performance. Any idea if I could revert back to the ND8 modem and fix WiFi if I install the NDC modem?

What about the modem? I've looked everywhere and haven't seen anyone attempt to use the modem that comes on NDC being used on ND8.

Give it a while. I thought the same thing but as soon as I moved around I saw what everyone was complaining about. I recently took my phone on a road trip from Texas to California and along the way, I kept getting so many dropped data connections. I knew LTE was butchered with the update, but I had no idea that the new update would make the S3 struggle to establish data connections with both EVDO and 1X. It was really irritating while streaming Spotify or tunein on a long road trip and having data services disappear on me. I know this isn't a network issue because it happened with sprint and every roaming partner along the way. I really hope they fix this issue. I dont want to upgrade since that would mean giving up SVLTE and SVDO in exchange for the tri-band feature.

I'd also like to add that I pick up LTE back up just as quick as MK3 did but ONLY if I am in an area with good reception (-99 to -105). If I'm in an area with bad reception, forget about it.

After further use of this new ND8 modem, I have now came to the conclusion that the new modem is as bad as advertised. There are location I have visited where I would lose LTE, but once I left them I would pick up a weak LTE signal fairly quickly again with MK3. With ND8, (based on my observations) it seems to ignore a weak LTE signal (even if its usable) and only go back to LTE if it comes in at -112 dBm or better. That was not the case with MK3 since I used to see it switch back to LTE at a weaker signal. This is so far what I observed and of course you can always manually scan and latch onto LTE (even if worse than -112) by toggling airplane mode. As far as losing LTE, I haven't seen much difference in that threshold. Both MK3 and ND8 lose LTE at the same places as before. Overall, I'd say that this new update worked wonders on the ROM and WiFi connectivity, but ruined LTE connectivity. I hope sprint pushes out a small update for the modem and leave the rest as is.

I really don't see a difference in signal strength for LTE with ND8. Compared to MK3, the only difference I see is that it takes slightly longer to go back to LTE from 3G. Overall, the entire KitKat update seems to have given new life to this phone. I really don't mind the new ND8 modem since my area is fairly advanced as far as NV upgrades go so 3G is usable again if I ever fall to it. One thing that people haven't really noticed is that WiFi works now. On 4.3, if my phone sat on the edge of my WiFi network, the speeds would be so slow that the phone would kick me out to LTE automatically. Now, my signal is a lot better and my speeds are way faster on on the same location. Before, my WiFi speeds on fringe area were 3-6 Mbps, but now on the same location the WiFi is anywhere from 13-18 Mbps.
