I created a tool a while back for Galaxy S II owners to backup and restore the '/efs' partition and perform basic NV Repair on their devices.
This proved so popular that I recently updated the application which now includes a feature to automatically detect the mount point of the '/efs' partition. This allows any supported device to be used with EFS Pro and also adds support for future devices.
Check out the link below for more info and download:

Nice to see you here lyriquidperfection. Used your tool for my S2 few months ago. Works wonders. Cheers!
I actually spot your program a few days back in the GSII forum, the EFS file seems small, should not be a problem right?

Guys,
for those of you having issues with the app, just do it yourself. It's not like it's complicated:
su
dd if=/dev/block/platform/omap/omap_hsmmc.0/by-name/efs of=/sdcard/efs.img
Done. The file will be called efs.img in /sdcard.

EFS Pro has now been updated to v1.8.3.
Nexus S / Galaxy Nexus support has now been fixed hopefully.
Differences in the 'efs' location, name and partition layout was causing issues.
Please test this new version and post your feedback please as I dont have a physical device to test on.

There's another app I know of that claims to be able to back up and restore efs on the gnex and some other galaxy devices. It's called kTool and you can read about it here:
http://forum.xda-developers.com/showthread.php?t=1314719
or search for it on Playstore.
It seems to back it up OK, but I hesitate to do a test restore, since a problem there could permabrick the phone. Has anyone actually personally verified that kTool restores the efs partition reliably?

Hi, efrant. I assume the efs partition or IMEI is checksummed somewhere in such a way that you couldn't simply dump the efs, alter the IMEI with a hex editor, and write it back?

That's an excellent question. It is and it isn't. Have a read of this thread. (I honestly haven't really looked into, but I guess I could if there is a need for it. And I don't really want to get myself or XDA in trouble by talking about cloned IMEIs. )
Yup. Ditto.
thanks for your efforts putting this together OP.
suggestion: this could be moved to themes & apps, perhaps?

You can flash TWRP 2.2.2.0 recovery and boot it. It has an option to back up efs.

Hi
I having a huge problem, i restored efs img through efs pro (latest version) and it mounted and pushed files ok, but before it finished it wrot efs backup is corrupted (or similar) do not use this backup.. and then rebooted phone - and since there have been NO way to mount/delete/format the efs dir on sd, cant root, install rom from cwm or anything because its totally locked it seems, installed twrp 2.3.3.0 and its working, but im not able to mount efs dir from here either , i tried format all data/cache/system/sd but still unable to mount efs it says????
and says there is no sim card even there is.
Only thing i can is flash stock rom from sammy but not latest v 4.1.1 only v 4.0.4 then it boots to os but tells me its in factory mode (no wi-fi bla)
if i flash 4.1.1 its gets stuck on galaxy boot logo - tried flashing syiah 1.86 through odin but just hangs on siyah logo!!!

Yeah this is what it says in flashing instructions:
For Odexed, Deodexed, Kernels, and Modems use CWM or TWRP to flash.

For Factory Image use Odin.
__-- Unzip the downloaded file and flash ".tar.md5" via Odin. Ignore "SS_DL.dll". Will LOOSE data and root. Back to Factory State.
____-- If you boot loop go back into recovery, do a factory reset, and reboot.

And then you put it on the root of your sd card then boot phone into recovery (thats if your rooted and have a custom recovery , like cwm or twrp ) (get into recovery by having phone off press volume up and home center button and power button all simultaneously until I see the galaxy note II as creen let go of power but hold volume up and home buttun until your in recovery , then let go of buttons ) then go to install if in twrp navigate to the root of your sd card and selct the modem zip and press flash after that reboot and you should be good.

Thanks, I don't know whether or not there is a custom recovery, as I just got the phone and it came with the Jedi rom, not sure if that is cwm or twrp. And I've never rooted a custom rom or other zip before but this post certainly helps.
How do you put it in the root of SD Card? The internal one in the Note 2 right? Is there a specific folder I put it in?
And which file am I taking from the modem download? Just the .bin? Do I rename it?

Do yourself a BIG favor... slow down!!!! Start by doing a LOT of reading. Search button works great here... use it! You've never done any of this before, and if you do something wrong you are going to be posting "My phone won't boot" or some other thread that says your phone is dead.
Since you just bought the phone and it has a custom ROM, it has a custom recovery. Start by making a backup in recovery, and save to your sd card so you have something to fall back on.
Don't be silly an be too anxious and brick your device.
NO problem, if you have the jedi rom I can guarantee u have a custom recovery so just go ahead and take the steps I told u and u should be good . Having any trouble Pm me or watch some Youtube videos .

Based on your questions, DO NOT ATTEMPT to Flash the modem. You need to read up much more BEFORE YOU START.
One, wrong flash and you are screwed. Make sure you back up your EFS partition before you start so you dont loose your IMEI.

All right, finally the baseband version is now updated to T889UVBMB4
Hello everyone, firstly I'd like to apologize in advance if this has been answered before. I searched and could not find a resource to help me with my problem. Here goes, I recently purchased a SGH-T889 Galaxy Note II. I managed to unlock the device and popped in a AT&T sim card. All was well until I decided to flash the AT&T varient stock firmware on it and that's when everything went wrong. Odin failed at the very end of the flash and the phone would not boot. I flashed back to TMobile stock and the phone boots into the OS fine but now the IMEI is blank, the baseband is unknown, and it says there is no SIM inserted. I also noticed when the phone is connected via USB the internal storage is not accesible, says there is 0 space. After searching around and reading up a bit it seems I have screwed up my EFS partition. Being the extreme noob that I am unfortunately a backup was not made prior to flashing. Am I screwed? I've tried reflashing different versions of the stock but I still get the same results. Is it possible to use a EFS backup from a different phone and insert the IMEI from my phone? Any help will greatly be appreciated.

Flashing to stock is not your problem. If you're booting you're fine. You will need to restore your imei now. There is a guide in development (edit I actually didn't find it when I just checked, but that guide above should work). I'm sure you realize this now, but never Odin something not made for your phone.

Thanks for the links. I don't have the phone on me at the moment but will give this a try and hopefully this will fix the issue. When this happened to you were you able to see any internal storage from your PC and or the phone itself? When I went into the storage area under settings it displayed how much space was being used by the apps but it also said 0 was available.

Hello there,
Im with a big big problem right now, I was at Slimbean ROM 4.3 (JB 4.2) and triet to install original Samsung rom via ODIN, when I did I lost my EFS folder, IMEI, etc., but my phone did turn on and i could use it except for calls and messaging.
After several tries to restore my efs folder again (I had an efs folder "efs.tar" that is about 3mb but dont remember which program i used to create it) it simple doesnt turn on and is stuck at Samsung Logo, i tried instralling original ROMS via ODIN, custom roms via CWM and nothing of that works, i can copy files from the efs.tar backup file to the efs folder, but after i reboot it all dissapear and the efs folder is empy.
I tried lots, and I mean lots of ways to recover my efs, or even boot my phone but i get no luck at all.
If anyone can help me please, there is no way to send to Samsung at all.
Thanks in advance,

I cannot turn on the device, i cant acces my phone, only CWM recovery and download mode.
Already tried one of those but when i click on mount /efs i get an error telling Unable to mount /efs!
Maybe if I could get an efs.tar that my Odin could accept i could start the phone, and later copy all my efs files to the efs folder, but i cant find any.
