[Samsung Galaxy Gio GT-S5660] V a L y O:
Hello. I need help with backing up my /efs folder. I tried different methods and none seemed to work.

Phone: GT-S5660 Gio

Network Lock [OFF]

Network Subset Lock [OFF]

SP Lock [OFF]

CP Lock [OFF]

Android: 2.3.3

PDA : S5660XXKPO

PHONE : S5660XXKPA

CSC : S5660OXFKP5

Lurking the forums I tried different methods with no luck:

C:\sdk>adb shell

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

$ su

su

# tar zcvf /sdcard/efs-backup.tar.gz /efs

tar zcvf /sdcard/efs-backup.tar.gz /efs

tar: not found

# exit

exit

$ exit

exit

=======================

C:\sdk>adb shell

$ su

su

# busybox tar zcvf /sdcard/efs-backup.tar.gz /efs

busybox tar zcvf /sdcard/efs-backup.tar.gz /efs

tar: /efs: No such file or directory

tar: error exit delayed from previous errors

# cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img

cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img

/dev/block/stl3: Invalid argument

# exit

exit

$ exit

exit

This method creates efs_dev-block-stl3.img (0 bytes) and efs-backup.tar.gz (29 bytes)

=======================

EFS Pro

Checking Device Connection... Device Connected!

Restarting ADB Server... Okay!

Checking ROOT Access... Device Has ROOT Permissions!

Backing Up Device's '/efs' Folder, Please Wait...

Creating EFS Backup TAR Archive... EFS Backup Failed!

Operation Finished!

With the ISO option the program freezes.

=======================

C:\sdk>adb shell

$ su

su

# dd if=/dev/block/stl4 of=/sdcard/efs.rfs

dd if=/dev/block/stl4 of=/sdcard/efs.rfs

/dev/block/stl4: cannot open for read: Invalid argument

# exit

exit

$ exit

exit

=======================

I also tried this:

With Root Explorer I am unable to find the /efs

Sorry for the long post, but what am I missing?
