I encountered the above state when trying to copy an image to an ex4550.

I factory-loaded the box, set up the root password and basic IP for reachability to the box that has the images and was able to copy the image & finish the upgrade of the box.

PS: Ensure you back up the configurations.

rebooted the box at this point and the upgrade was as smooth as ever.
