    The /efs file is the unique file containing, among other things, your IMEI code and its loss or corruption renders your phone useless which is why, after rooting, you should make a backup of your /efs file and keep it somewhere safe on your PC or the cloud, or both. See, Getting to know your EFS folder on Samsung Devices

    If, as per best practice, you have previously made a nandroid backup of your phone, there is a good chance that your custom recovery will have included your /efs file in the backup and you can restore it from the backup.
