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,
DCastro555

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.
Have you read link i have attached?
That's you have to do in recovery.

Yes I read all link, the efs.tar i have is only 2mb, and i have no efs.img that is needed, and i dont know why my adb shell is not working, my cmd doesnt recognize the "adb".

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.

Actually had a proper back up already, just toying with the programme.

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!!!
What do i do ? is the phone softbricked or what PLZ help out - big thanx in advance
Hi there, just bought a new N7100 and because I'm using Linux mint I decided to root my phone using Exynos Abuse and to be honest this was really simple....Then I installed ROM Mnnager, and set up CWM recovery from within ROM Manager. Now then, CWM has installed but whenever I try to reboot into CWM I just get stock recovery....
Is there a simple method to resolve this problem????
Thank you in advance

Download the recovery from cwm site.
If it is in .img format then rename it to recovery.img and flash it via mobile odin.

Did you search your entire device for the folder efs_Backup? It should create automatically. If you don't find that. Use note2 toolkit and restock.

I have a phone backup not the EFS backup. The Imei got corrupted all of a sudden. Next time i'll keep a EFS backup. i have few stock roms but i don't have Modem / recovery Roms and i found this thread " http://forum.xda-developers.com/showpost.php?p=31986738&postcount=6 " but the links are dead. You got any links to download stock ROMS along with Modem / Recovery / Bootloader , then please do share. Also, ROM links are slow if you can provide fast meta link that would help.

I went back to the stock rom on my Galaxy Note 2 (Telus i317m) and now my IMEI, IMEI SV, memory and baseband are no longer registering so I am unable to use my phone and no internal memory available. I have tried everything I can think of. I backed up my IMEI and EFS and NV. When I plug my phone into the PC with NV items reader writer, QPST, EFS Pro my phone is recognized and then when I try to write the NV data to the phone it is no longer found by all programs. I cannot install busybox because my internal memory is no available and tried to an SD card, but it won't install on the SD card. I followed eveything to the dot or at least I thought I did. I have done this before with the S3 with no issues. Below are images of what my phone shows. TIA.
did you "NAND ERASE ALL" when you were flashing your stock rom through ODIN?
Did you format your system?

Yes I did using twrp as I have always done.
If you Nand erased the device by mistake you have killed the device partitions. ..
Fully wipe the device in recovery and boot into download mode. ..Then push the rooted stock rom of your choice via Odin...Then reboot. ..
If the IMEI and EFS folder are gone the device is likely dead...
A repair is possible by the folks at mobiletechvideos.com..
They can restore the partitions and fix the device. ..
See their website for more information and cost. ..g

Workaround:
Make use of your installed/reinstalled recovery system to restore a rom or better nandroid-backup that is already as close as possible to your stock firmware. From there the kdz flasher should work (at least according to my own experience).
This backup worked for me(E986)

I had 2 times problems with low battery issue. I passed it only changing from Diag mode to emergency.
And also it seems to me that the kdz flashing procedure passes only randomly without battery issue. But only on emergency.
I also reinstalled all drivers to reactivate usb ports. With some patience it should pass through
