Thanks a lot
what phone model do you have??
1. when you say you loaded a back up what backup did you load? the phone backup or the EFS backup?
2. if incase you loaded the phone backup I would suggest you first backup your EFS this partition stores your IMEI and other network sensitive parameters...if this partition is corrupted or destroyed you won't have any network on your phone.
you can Google or search on XDA the tools for EFS backup... I think one of them is EFS backup pro...I would suggest use multiple tools for backup just incase as sometimes incase you want to do a restore and it fails you have an alternative backup and tool
3. try searching for other networks in your wireless connection settings if you do get a list of networks (not Wi-Fi !) then their might be a SIM registration issue or even the NETWORK MODE ie. GSM,WCDMA,LTE so try keeping your network in auto mode for now
4 try changing SIM cards, if still problem do the below step
5 flash another modem
6 if step five fails get a completely original Samsung stock ROM flashed via Odin including its .pit, acc and modem
7. if all the above fails....there is a technique of repairing/recovering EFS this is your last hope ! just Google it or search here on XDA you could also start with step 7 before step 5 & 6 as long as the method doesn't involve modifying stuff alot or whatever you do is reversible
all the best
