Invalid IMEI after installing ROM



Hello,
I've Galaxy S III,
I tried to install an official ROM on the device
It's baseband version is : XXUGNA8
After installing,
The IMEI became invalid and it became 04949....
Are there any way to restore it without box service
Note : My device isn't MTK and I didn't have any backup from " efs " folder
Help me :(
Thanks !
