Default ROMs Removes Modem - Cannot Restore Modem

Ill admit that Im not the best at this, but Im not too new to rooting, roming, or flashing (so now you know I might be the reason). Out of all, I've never done anything like the Sprint Note 2 where flashing a ROM removes all phone info, IE. IMEI, Baseband Unknown.

I tried restoring EFS and Modem (which I backed up beforehand); manually installed modems; all to no avail. Basically I have to recover by starting from scratch using http://forum.xda-developers.com/show....php?t=2591898.

What am I missing?
