[HEAD]Other Infos[/HEAD]

This Tool is for Backing up the /efs folder!

In the EFS Folder your IMEI and other very important Files are stored!

It's a MUST to back it up!

A corrupt ROM or Script could change this Folder, like we have seen at Nexus Sense or TWRP !

adn I don't want to say something bad about the Nexus Sense Dev! He is a very good Dev and I only want to bring a example for this Tool!

[HEAD]HOW TO[/HEAD]

Make sure you have USB Debugging ON!

To back it up run efs_backup.bat / efs_backup.sh

to restore it run efs_restore.bat /efs_restore.sh

i see EFS everywhere and i dont know what it mean can someone break it down for me
EFS is a direction in the root of your nand, /efs !

in this direction are some very important files stored! these files contain the IMEI and other important information! this is the main thing!

the problem is when a updater-script is written false the this can cause the problem that the updater-script deletes/formats the /efs and your IMEI is gone!
and the only one that can restore your IMEI is Samsung so you have to send it to Samsung or you will get blacklisted by your provider, because you use a generic IMEI !

hope this helps
