another alternative is to try the following using ADB or Terminal emulator

su
cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img (OR)
busybox cat /dev/block/stl3 > /sdcard/efs_dev-block-stl3.img

then using a Linux distro such as ubuntu

Copy efs_dev-block-stl3.img to the computer with ADB

ADB pull /sdcard/efs_dev-block-stl3.img ~/efs_dev-block-stl3.img

sudo mount -r -o loop efs_dev-block-stl3.img ~/efstemp

browse to efstemp
nv_data.bin should be located in this folder

Use ADB to push this file back to the phone

ADB push ~/efstemp/nv_data.bin /sdcard/nv_data.bin

ADB shell

copy nv_data to EFS directory then remove MD5 file

cp /sdcard/nv_data.bin /efs/nv_data.bin

rm -rf /efs/nv_data.bin.md5
(OR)
busybox rm -rf /efs/nv_data.bin.md5

change the permissions on the file
chmod 700 /efs/nv_data.bin

change the owner of the file
busybox chown 1001:1001 /efs/nv_data.bin
or
chown 1001:1001 /efs/nv_data.bin

Most of these details have been taken from the following site

The phone will be require to be rooted for this to work
