How to restore an image of android partition from my linux PC

I created an image of my flash disk of my Nexus 4 as described in this thread by doing

# adb pull /dev/block/mmcblk0 mmcblk0.img

The image is fully functional but I would like to push this image back to my phone and the inverse command is not working since stays there forever and no change is done.

# adb push mmcblk0.img /dev/block/mmcblk0

How can I push this image back to my phone?
