--- ERROR OCCURED

The backup of your EFS partition could not be created.

Please contact me by xda developers and post this output with an explanation
of what you exactly did. Include also your phone model and Windows version.

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.
