For me, following OP instructions worked, end result was EFS file of type 'Disc Image File' 20 MB size

I will guard it with my life. Hearing others explain how a ROM flash wiped theirs makes me nervous...I am about to flash my 1st ever GT7100 ROM wish me luck. My 1st phone was a Nexus S, and EFS corruption wasn't ever discussed in the forums. Is it not an issue with Nexus phones?

Anyways thanks OP

Can I restore the efs.img using the CWM?..

I think you need to run the script, not CWM. The files in the first post can do that for you.

Ok thank you.. But what if the phone won't boot in the main screen, is it possible to restore using CWM?

I think CWM does not do that for img files. But I could be wrong. Personally I never did so.

Hey guys is there any way to restore IMEI from download mode? What happened is that i tried flashing ARHD coming from WanamLite 3.8. Did a full clean wipe install tho..after booting up, i noticed my IMEI wasnt the one i had. So tried restoring my IMEI from my EFS backup using Terminal Emulator. Then after rebooting my phone was stuck in bootloop. And now thats all it is. It just wont boot up. I tried restoring to stock via ODIN and still phone wont boot....Any ideas?

Sorry if this has been asked before but when running the script all I get is this:

Any solution? Tried to uninstall KIES but it doesn't help.

@corvux360

what i did i to flash the rom i want then i did extracted the tar.gz file so you've efs folder extracted so after i've flashed the rom i deleted EFS folder in my phone and i reboot you find no lockscreen and some words in yellow copy EFS backup folder you extracted before to the same location you deleted your device EFS folder then reboot service now should work if not so apply the following commands in terminal emulator line by line and press enter after every line:

su
rm /efs/FactoryApp/keystr
rm /efs/FactoryApp/factorymode
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot

Descompact .tar.gz

To descompact .tar.gz I use this:
On Pc, black screen:
adb shell
gzip -d /storage/sdcard0/efs.tar.gz .. or .../storage/extSdCard/efs.tar.gz
Now I have efs.tar only on device.
If extract this tar I have efs/files. I can copy efs/files to root/efs.
I verify permissions and alright (in my succeeded cases).

On device whit Shell Terminal Emulator work well also.

Nandroid backup provides a proper EFS backup, right? Asking because i can't get this method to work..

Will this work on any GN2 or just the N7100?
