[TOOL] EFS Pro - Advanced '/efs' Backup, Restore, Repair!

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?

Not working with my Nexus. It gives the error operation failed at the time of detecting the EFS partition on the phone.
Running AOKP M5 and the phone is GSM

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.
Pressed from my Maguro

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?

No claims about my tool! EFS Pro does exactly what it says on the tin! Tested all functions myself!

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

If i remember correctly flashing rom doesnt wipe out ur imei

IMEI will not get lost in any circumstances... So far flashed as many roms & zips & still not a single error. Also, I think that there's no particular method for backup or restoring IMEI.

better not use that.
without doing something wrong while unlocking, your emei will not be removed/corrupt or what else.
so just dp the right things, no need to make a backup, wich may result in losing it top

EFS forders, lost imei. no backup

it's no method solve this problem ..? :crying::crying:
i solve i9305, write imei method , but 7105 is write protect ,read only ..

Happened to me when I flashed ROM via mobile Odin. I just flashed stock ROM again and got my IMEI/baseband back... worth a try.

nothing can be done at this point you will have to pay for the support.
Always remember to make a backup of EFS before flashing files.

When did the problem start exactly. My guess is that its an efs structure problem. Done by updating to a newer samsumg rom TW etc..
Also, are your imei and serial intact Nazgul?

Read up on that before you install it. It may not be exactly what you are looking for. Just a heads up.
Its usually used for no imei and serial. Not the same issue you are having. But as I said, read up on it

Its used for patching your existing imei and restoring not only for no imei

I'm having turkey for Turkey stock rom DMF3 installed and registered on the network says it's not the same as normal, but still there is no network only fault imei patch was installed, but I do not want to root stock would I want to use my phone with original rom thanks for the help. .

[HELP PLS] IMEI, IMEI SV, internal memory and baseband gone.

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
