Backup EFS

I downloaded a program called "7 Zip" and extracted the script. This is probably a stupid question but where do you run the script? Tried the CMD prompt and the script will run but it does not do anything to the phone. It just runs on the PC and returns an error "file not found". I did have the phone connected in download mode but nothing happened.

Oh, I just read that you have to give root permission to ADB. Apparently you have to run the script in ADB?

Where do I get ADB and how do I run the script in it? Step by step instructions would be much appreciated.

EFS Backup
The script appears to work on the Samsung Galaxy Note II SGH-I317 (ATT).

It put a file called efs.img into the same directory as the backup.cmd file. That is fine.

I am comfused about where it put it on my phone. I performed a search for efs.img and found it in two places. Is that correct.?

I found it at /data/media/efs.img and also /mnt/sdcard/efs.img. The time stamp corresponds to the date and time that I did the procedure.

Is it working as intended or is something amiss?

Thanks a bunch!

Well ,the backup cmd,
didn't copy the file on the working folder on the pc,
so i found it in the sdcard folder of the smartphone (which is the built in storage on samsung devices),
and copied it my self .

The file is 20 megabytes.

Probably some access rights issue..

I'm trying to do a restore using the script, but keep getting the same error message:


Press CTRL+C to cancel

'CHOICE' is not recognized as an internal or external command,
operable program or batch file.

--- Push efs image "efs.img" to phone "/sdcard/efs.img" ---
The system cannot find the path specified.

--- Restore efs image "efs.img" from phone "/sdcard/efs.img" ---
The system cannot find the path specified.

--- TRY KILLING ADB DAEMON / EVENTUALLY SHOWN ERRORS BELOW CAN BE IGNORED
ERROR: The process "adb.exe" not found.

--- RESTORE SCRIPT IS FINISHED

Your EFS partition is restored from "/sdcard/efs.img"

For any feedback or when having problems feel free to contact me at XDA.
Please include also your phone model and Windows version if you have problems.

Press any key to continue . . .

This is driving me up the wall at this stage.

Is it possible to backup the EFS from an old Samsung Galaxy S2, and restore it on a new phone like the Note2 or Note3?
So we could have a spare EFS backup in case there's a problem with a new phone...

My guess is that the EFS files have an identical structure on all Androids and don't change with different models/manufacturers.

Hello,

I have a tar.gz file with my EFS backup and not a .bin one.
Can I use this script to make the restore or what is the best method to restore my IMEI in my International GT-N7100?

Thanks in advanced

Hi friends....

Im really confused here.... I downloaded the zip file (340kb) and have it on my desktop... When I use WinZip to extract the files, it gives me an error... However when I double click on the file, WinZip Window opens and shows me 5 files in it ; Adb.exe , AdbWinApi.dll, AdbWinUsbApi.dll, efs_backup.cmd and efs_restore.cmd.

Plz advise...

Thanks in advance

Now that you have your efs backed up since my tip to use winrar to extract worked, could you leave other users any tips that would help while doing this process.
