[Q] Backup /efs folder?

Hi,
I came from Galaxy S2, on which I learned that it is crutial to backup the /efs folder with nv_data.bin file immediately before messing around with the phone.
unfortunately I can't find the nv_data.bin file on the S4 in the /efs folder or subfolders. Where can I find it?
I have an unlocked rooted i9505

Hi,
I am using root explorer and see the contents of /efs, but there is no nv_data.bin file in there. Is this file located somewhere else on s4?

Is your phone rooted ?
If so , then only proceed.
Otherwise NO root , No party.
For rooted device only :
1. Download the file from the given link.
2. extract the files and folders from the rar.
3. copy the .qmg files and the audio folder to system/media (you can use any root file explorer).
4. And most IMPORTANT - give proper permissions to all the related files and folders.
5. Reboot and enjoy the party.
For permissions:
files ---- 0644 (rw-r-r)
folders ---- 0755 (rwxr-xr-x).
