You'll need an app that can write your IMEI to the phone. Since I've never gone down to that level without first making a backup of the partition, I never saved a link to any app that would do that (I can always restore the partition), but you can look on Samsung Galaxy S III I9300, I9305 - XDA Forums to see if anyone has posted links or other methods of writing the IMEI to the phone.
