    EFS back up through terminal emulator.

    I have been reading around about how to use terminal emulator to back up your efs. I found alot about other s4's but couldn't find anything for our variant. There was only a few variations in the command to back up between variants. So I decided to perform efs back up through philz advanced cwm touch. While philz was backing up I was reading the lines philz was displaying. I saw the command that was used for the 9505 type s4's. I couldn't find the back up that philz made so I decided to try terminal emulator using the information I gathered. This is what I typed in.....
    1.su
    2.dd if=/dev/block/mmcblk0p10 of=/sdcard/efs.img

    I succeeded in creating an efs.img onto my sdcard. My question is. Do you guys think that this is an actuall back up of my efs? Or is it just some random file I created and named it efs.img? I'm willing to email some one the file if willing to take a look and tell me what they think. Thanks to everyone. I just want to be secure in worst case scenario if my efs/imei gets wiped/cleared/nulled.
    As for restoring your efs that would be simple as this command....
    1. Su
    2. dd if=/sdcard/efs.img of=/dev/block/mmcblk0p10
    3. Reboot your phone and you efs is restored.

    I'd like thanks to Mr.W0lf for providing the community with this method.

    Just in case anyone was interested in backing up your efs. I can confirm that the method I used was correct. I liked it because I didn't need access to a computer and can restore on the go if something happened to my efs.
