AFAIK this partition is an exclusive partition on Samsung devices...
Isn't it efs on Samsung?

Yeah you're right! Is it a spelling error? Never heard of esf...
Nexus 4 doesn't have a efs partition.

If your friend is lucky few ROMs will take EFS backup in SDCard and there are tools which can restore IMEI number. If you do flash other roms then better take a backup of efs folder. using root explorer you can archive and store efs folder.

There isn't an efs partition on nexus 4. It's a samsung thing. Galaxy nexus had it because it was made by SAMSUNG
Backing up ur ESF Partition
U need Root,Android Terminal Emulator and busy box to successfully backup your ESF Partition. Type the following codes to backup/restore the ESF partition.There is another block mmcblk0p10 which contains the m9kefs3.img however the same is blank(So backup not mandatory). The m9kefs2.img contains the IMEI information. Also kindly backup the same to ur PC / Email or Drive
Also these codes remain the Same for Android 4.4(Kitkat) & 4.2(JB). However for Android 4.3(JB) change the storage path to storage/emulated/legacy
Code:
su
dd if=/dev/block/mmcblk0p8 of=/storage/emulated/0/m9kefs1.img
dd if=/dev/block/mmcblk0p9 of=/storage/emulated/0/m9kefs2.img
Restore.
su
dd if=/storage/emulated/0/m9kefs1.img of=/dev/block/mmcblk0p8
dd if=/storage/emulated/0/m9kefs2.img of=/dev/block/mmcblk0p9

I tried to delete nv_data.bin and nv_data.bin.md5 in order to recover original version from .nv_data.bak and .nv_data.bak.md5 after reboot but failed.
Firstly I remounted efs partition with -w flag:
Code:
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
First file've been deleted but for second message 'read-only system' shows up. And when i unmount and then mount again first file appears again.
I tried to do these from terminal emulator, adb shell from booted phone and in recovery mode (with CF4 installed).
My firmware version XWKE7. I bought phone as sim free at clove.co.uk
Can anyone suggest what can i do?
From what I have read from the SGS forum if your efs folder is missing your imei your stuck, only thing to do is flash some stock FW from odin and return it, hope you can return it under warranty mate.

You could try the backup and restore efs post from dev section if you have not already .

You can use TWRP recovery to get a EFS backup

You can back up a whole partition with Terminal Emulator from Play Store.
This is example made for I9505 ONLY!!!!
For I9500 use mmcblk0p3 and efs.img instead!!!
Download it , and run it, then type:
Code:
su
dd if=/dev/block/mmcblk0p10 of=/mnt/sdcard/efs.img.ext4
and it will dump whole partition into one file efs.img.ext4 on your internal SD card
or
Code:
su
dd if=/dev/block/mmcblk0p10 of=/mnt/extSdCard/efs.img.ext4
to save it on external SD.
If something goes wrong and you need to restore it:
Code:
su
dd if=/mnt/sdcard/efs.img.ext4 of=/dev/block/mmcblk0p10
or
Code:
su
dd if=/mnt/extSdCard/efs.img.ext4 of=/dev/block/mmcblk0p10
Keep it safe and enjoy

With all respect to your post, I would like to warn people that this is not working for all the models/devices. Although it might look fine when executing the commands, it might not have made a backup of EFS, but of something else... What I know for sure is that it will not work for atleast the international i9505-model of the S4, as the partition layout is different.
In my post below, more details are given on this partition id.
http://forum.xda-developers.com/showthread.php?t=2276599
While executing your commands does not affect the device, it does not always give the people a backup they expect it to be, depending on their device/model. In my case you are able to verify which 'mmcblk' is actually efs on your device. It also gives a TAR backup as option.

Mate... I've added that it is for I9505!!!!
I9500 have EFS located @ mmcblk0p3...........

I used GS2 repair from play store. It went through the usual process and I can see the back up file on the sd card. Can anybody more qualified confirm if this app works on S4?

Great. You are right, in my case it's mmcblk0p10 as well, as mentioned correctly in my guide already.
Thank you for updating.

The best thing is to check it with the developer. I do not know what file has been created, although I expect it to be a raw copy using dd. The best thing is to do it manually. Or by the instructions given by djembey, or by the more detailed step-by-step instructions in the thread of my previous post here.
Hey, I managed to backup the EFS folder. Is there any way to modify the backup file and restore it after the modification? I want to change the IMEI number but unfortunately I have no box / cables available to do so. There must be a solution?! I am currently living in Turkey and they restrict western mobile phone usage for foreign people.
thanks a lot

TWRP also has efs backup.
On i9505 you can do it manually using terminal emulator dd command and then copy the backup files in a safe place.
su
dd if=/dev/block/mmcblk0p10 of=/mnt/sdcard/efs.img.ext4
dd if=/dev/block/mmcblk0p13 of=/mnt/sdcard/m9kefs1.bin
dd if=/dev/block/mmcblk0p14 of=/mnt/sdcard/m9kefs2.bin
dd if=/dev/block/mmcblk0p15 of=/mnt/sdcard/m9kefs3.bin
Don't know if it's the same for i9500.

Yes. I have backed up my Efs using this tool..
open the thread and search i9500 you would get to see it is compatible.

I change my i9505 to i9505G.. i can use this location to backup my IMEI etc..?
is there a difference for using the same tools for the differents models of SGS4?
For I9500 try these to backup.
su
dd if=/dev/block/mmcblk0p3 of=/mnt/sdcard/efs.img
dd if=/dev/block/mmcblk0p4 of=/mnt/sdcard/m9kefs1.bin
dd if=/dev/block/mmcblk0p5 of=/mnt/sdcard/m9kefs2.bin
dd if=/dev/block/mmcblk0p6 of=/mnt/sdcard/m9kefs3.bin
Beware! make sure you type it exactly!
Also, EFS Pro works fine on I9500.

So I think I lost the efs files while flashing cm10.2. I do have it backed up in my stock rom,but I can't restore it because of a 'E: unable to mount /efs' error in twrp. I still have my IMEI, can make calls and sms, but the efs folder is empty according to root browser, es file manager and twrp. What can I do to fix the unable to mount /efs thing? Thanks!
EDIT: I'm using a GT-i9505
If you don't succeed otherwise flash full stock rom with PIT and restore your backup. Backup internal sd first.

I wonder if you can take your backed up efs folder and push it back onto the phone with adb??
Or, download EFS12.tar file then flash it, you done.

That is not for I9505, for I9505 u can clear EFS without risk. The problem is you already have a couupted EFS file, so no point to backup it.
