the tool you are using is for sparse images.
do you know what type of image you are trying to unpack.

try the mount command in adb to veiw what partitions are mounted and what type thay are.

Im pretty sure .dat is a sparse image.

.img could be ext4 or ext3 or yaffs or yaffs2 filesystem.

each image type needs specific binary tools for unpacking / mounting.

Give me some more info and i can help you
