Welcome to the forum Mazzgaming.

It sounds like your efs folder has been deleted. If you haven't backed it up you can try this app
https://play.google.com/store/apps/details?id=com.helroz.GSII_Repair&hl=en

Or you could try to recover manually using this guide
[GUIDE] Recover your IMEI in 9 steps. - xda-developers

If neither of those work it will have to be a professional fix.

hmm may be this is simple to find this problem

turn on your debugging mode and connect to your pc then note download the super one click there u will get adb kit folder get into it copy cmd to there and

enter cmd
type : adb devices (it shows the devices)
type : adb shell (now u will enter the shell of your mobile)
type : rild

on apply of this rild it gets you the result what files are missing from lib so collect it from previos roms and replace now your baseband get worked
 
I am facing unknown imei/baseband problem in my korean Samsung SII SHV-E110s so i have to bump this old thread..

when i did what you suggested than I got following message:

rm failed for /data/misc/radio/dlnk, no such file or directory
rm failed for /data/misc/radio/kmem, no such file or directory
rm failed for /data/misc/radio/ahrh, no such file or directory

so from where I can get these files so my problem can be solved. i have checked all custom and stock roms i have for these files but could not find it..
