Phone [Q] IMEI has become unknown

H All,

While flashing a new ROM CM 10.2 to my Samsung S3, my IMEI has become "unknown" and and due to that i have no network.

I am searching for a solution for that past 2 days and learned a lot but didn't find a specific solution, found a lot of tutorials with broken links, etc...

Please HELP!!!
I didn't found a working stock ROM too.
please i need a full help here.

ps.: i don't have a backup of my efs folder and my phone wasn't blocked or something

Thanks in Advance
