download terminal emulator to your I9500. open it and type (enter, after each command)
for backup:
Code:
su
dd if=/dev/block/mmcblk0p3 of=/mnt/sdcard/efs.img
dd if=/dev/block/mmcblk0p4 of=/mnt/sdcard/m9kefs1.bin
dd if=/dev/block/mmcblk0p5 of=/mnt/sdcard/m9kefs2.bin
dd if=/dev/block/mmcblk0p6 of=/mnt/sdcard/m9kefs3.bin
to restore if something goes wrong :
Code:
su
dd if=/mnt/sdcard/efs.img of=/dev/block/mmcblk0p3
dd if=/mnt/sdcard/m9kefs1.bin of=/dev/block/mmcblk0p4
dd if=/mnt/sdcard/m9kefs2.bin of=/dev/block/mmcblk0p5
dd if=/mnt/sdcard/m9kefs3.bin of=/dev/block/mmcblk0p6
NB Beware! make sure you type it exactly!

Will this also work for the I9505 model of the Galaxy S4? I've attempted to run /efs backups using the terminal emulator (with root access) with a different set of commands, but I keep getting the error message "tar: not found"...

dd command is great for that purpose... Actually it can backup any partition... I would do them all and store them in my hard drive...
