[Q] Baseband version unknown topic

I rooted my phone for the first time and everything went fine. I backed up apps and setting using Titanium Backup. I did a full backup from CWM Recovery. I then did a factory reset and then restore from CWM Recovery. It booted up but I get constant "Process ..... has stopped" messages and I can't really do anything so I did another factory reset and went through the basic setup and everything seems fine except I now I have no cell network connectivity. The Baseband version says unknown. I have 4.4.2. Build KOT49H.I747UCUFNJ1, bootloader i747UCUFNJ1. IMEI says unknown. I tried to flash the NJ1 bootloader/modem from enewman17 but no change. What else can I try? Thanks
