Default [Q] No Connectivity on MJ9 4.4 ROMS

I Odin'd the MJ9 radio some time ago and have been able to flash 4.3 custom ROMS based on that radio with no issues at all. The problem comes when I try ANY 4.4 ROM. The ROM and Gapps flash and install with no issue. However, I don't have data or voice connectivity. I'll go into APN settings and it's blank. I've tried manually entering the values, but the changes won't stick. As a point of reference, I'm running the MJ9 radio with TWRP 2.6.3.0 as my recovery.

Ideas?
