Null IMEI, No Common Option on Service Mode: Can't Turn on WiFi and No Signal

I had my phone rooted, but recently messaging service stopped working and I also discovered phone calls were not going through. I unrooted it and now I have an empty efs folder and no IMEI or it shows it is null. I've tried the *#197... to get to Service Mode but the FTM option doesn't exist.

Also tried the bin fix with Odin and now I can't turn on WiFi either.

Hopefully you can help.
