We will do the simplest way by adb shell
- Have root privileges
- Download and install busybox

- SD Memory Card inserted (formatted in fat 32 from the same phone)
- Before you begin to unlock the computer with the file browser to do a full backup of the folder / EFS in SD and PC

su
cd /sdcard
echo "this takes about 45 seconds"
if [ ! -f /sdcard/nv_data.bin.orig ]; then
echo "copying file to /sdcard"
cp /efs/nv_data.bin /sdcard/nv_data.bin.orig
fi
echo -en \\x00 > out0
dd if=nv_data.bin.orig of=out1 bs=1 count=1578089
