Successfully created a backup for my SGS Captivate running CM10.1.3 (Also transferred to my laptop with my first adb pull.)
I hope I never have a need for it.

Thank you wanam. :D

Is it work on custom rom? like ParanoidAndroid?

The app successfully located the EFS location. So I try to make a backup, and it says successful. But, I don't see any folder called EFSBackups on sdcard directory. (both sdcard0 and sdcard1 (even sdcard2) :confused:

Samsung Galaxy SIII Mini (GT-I8190) running ParanoidAndroid-4.6-Beta5-unofficial.

While I can't make any efs backup, I just translated your apps to Indonesia through the app menu :D Maybe there should be an option to save the EFS on custom location. Will PM the syslog.

I am facing the same problem: I can't find the EFSBackups folder anywhere.... I can locate my EFS folder though.
Would really like to be able to choose a specific backup lcoation.
ROM: CM11 unofficial
Device: Note 3 N9005

    EFS backup updated to 1.4.0, the new update will backup any modem or extra efs partitions on your device as well as the main efs partition.

    According to some posts i saw here on xda, saving the main efs partition is NOT enough on some new devices, that's why i updated this App to save all other related partition.
