S5 Neo Bricked Corrupted EFS

[Gripes]

Help! My S5 neo g903f is Bricked after rooting. EFS invalid argument, stuck on blank screen after logo on booting. I've tried kies, smartsync, odin adb, twrp all to no avail. Any suggestions welcomed.

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.
