Long story short. I was on...
5.0.2 Build Number LXI22.50-14.6 24
I needed to be on...
5.0.2 Build Number LXI22.50-14.8 30

It should be - SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml.zip
After this, the original OTA worked and presently I'm on...
5.1 Build Number LPI23.29-18S.1
Dig IT!
But, the voice mail app updated after a wipe and is now constantly trying to send some stupid activation for the dumba** avatars nobody uses. It's the only thing I have seen with issues so far. Voice mails do come in. There was some sprint error that flashed up real quick, I don't know what it was though.
