[TOOL] Backup & Restore EFS (IMEI) for Samsung Galaxy Note 2 GT-N7100 / S4 GT-I9500

This is a simple script, to backup and restore the EFS / IMEI partition of the N7100 and other Samsung phones under Windows OS.

It is tested by me on a Galaxy Note 2 / GT-N7100 under Windows 8, but reported by users to work also for other phones, see details below.

Please let me know, if its also working on N7105, S3 or other Samsungs

See the attachment file and let me know, if it is useful to you.

Requirements before running the scripts:

• Developer Options -> USB Debugging must be enabled
• Phone must be rooted and root access given for ADB Shell access
• Phone Drivers must be installed correctly on your OS
• Connect the phone by USB and run one of the scripts

Reported Devices by users which are working:

• Galaxy Note 2 GT-N7100
• Galaxy S4 GT-I9500 (reported by "iznee", thanks)

Why my scripts?

I was inspired by batch scripts of xda user "as i9000".

But his "Windows" scripts did not satisfy me, because there where file not found issues, and in my opinion missing checks, that made me build up my own scripts from scratch...

- Do you have a SD card in the phone?
- Do you try to backup or restore?

Could you post a screenshot of the error? That might be helpful to investigate it...

I fear you have not understood what I was telling.I could not backup EFS as the Tool is is saying "error: write faileure during connection" and stopping there without making Backup.What might be the reason for the Tool is not able to establish connection with the phone?I have enabled the phone USB Debugging and Unknown sources.Also in my PC(Windows XP) the Firewall and Antivirus is disabled.I had also installed Samsung Drivers(not Kies).Now please suggest the remedy.

I understand very well.

I fear you did understand what information I need to give you support:

- Do you have an SD card, Yes / No ?
- Screenshot or exact copy of the console output to see at exactly at which position you get the error?

Other checks you can do:
If you use custom firmware, you can check the mount path of sd, because I create a temporary copy to /sdcard/efs.img. If the path dont exist it might give an error.
Try the script 2x because it might kill another version of running ADB at the end of the script.
If you still get the error try to run the command manually.

Open a console
run: ADB SHELL

You should get to a shell where you can access your phone and use "ls" to show the content of the local directory.

If you dont get that far there is something wrong with your drivers, OS configuration or phone...

Phone needs USB debugging enabled and it must be rooted / superuser rights granted over ADB!

This should not be a problem, it is just a cleanup action which runs as last command of the script to kill an eventually existing ADB process.

The "efs.img" file should be created in the same directory, where you also have the script files after running the script.

If it is there, everything is OK. Please let me know if the file exists and if not, do you have post a full screenshot or copy of the console output here.

 

[radiikal]

yeah that file exist. the size is 20,480kb

so am i cool now to proceed to flash rom?

Yes, everything should be fine. I have just updated the scripts, you might try it again with this new version.

The functionality is the same, I just changed the text outputs to make it more clear, that this error is not really an issue and additionally the full path to the created backup file is shown...

Ok,I am sure it is a great script. BUT, how do you open or execute it in windows 8? A (.7z) file extension is unknown to me and windows 8. Forgive my ignorance.

its very easy, u can unrar with winrar... go to "efs_backup_restore_windows_scripts_v3" folder and click on "efs_backup.cmd" , on your phone will ask to superuser grant thats all.
