@arkarain: Then see my first paragraph, it also applies on FW 4.0.x. Either restore default screensavers over SSH, or adapt the runme script from the K4 #I_can't_update_to_4.1.0 wiki page to the stuff you did. (That implies you have a backup of the default screensavers somewhere, or extract them from the forensic K4 images).
Or, join the 'hitting a nail with Mjolnir' fellowship, and follow the debricking stuff to downgrade to 4.0.x.
