Now it is clear that the thing that does not go well is that the image does not have a format but its possibly a block by block copy of the volume here is what asr says to me:

sudo asr restore --source /Volumes/MACCLN/MACOSX.DMG --target /dev/disk0s2 --erase --format HFS+ --noverify
Validating target...done
Validating source...
Could not detect format of volume on device /dev/disk1
Could not validate source - error 254

What can i do? How can i restore a block by block image? Is there any way to properly do this?
