[Q] Unknown IMEI/Baseband/SIM topic

There are quite a bit of threads pertaining to this particular issue, but most of these "fixes" require the files to have been backed up and simply be restored. I have no idea how I lost my service since I've always flashed new ROMs with a clean slate. A back up would be buried in the external sd card just in case. This time, I installed the N3BULA ROM v3.6 Android 4.3. I assumed the modem and other prerequisites were common since there were no links to obtain them, though I did seek out the modem firmware they mentioned. Once I booted, I had a circle with a line through it instead of the 4G LTE symbol or the bars. I CANNOT CALL, TEXT, NOR ACCESS DATA!! I would call it a brick, but everything else works just fine! I've done MANY methods to no avail. I've tried different stock ROMs, all did not want to activate and even when I reverted back to the exact ROM back-up I made prior to N3BULA, it had no service. My SIM card is still registered with verizon and from past experience, I KNOW a new SIM card ain't gonna help. I've been reading about a lot of **** coming from the 4.3 updates, but I never expected something like this...

HELP ME!!! I DON'T HAVE MONEY TO BUY ANOTHER PHONE OUT OF CONTRACT!!! (I have unlimited data still ^-^)

My device is the Galaxy Note II Titanium for Verizon. Model: SCH-I605
