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)

CHANGELOG - SCRIPTS LAST UPDATED 2013-05-11
  • v3 - Updated text output of the scripts
  • v2 - Updated ADB binary files

Hit the THANKS button if you like it!

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...

Dear,
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.

Tried flashing STOCK ROM 4.4.2, but still no luck.

Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED

IM using Note N7100 K.K.4.4.2

PLEASE PLEASE PLEASE HELP ME.

    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!
