New Release - WD TV Play Firmware Release 1.05.47 (3/25/2013)

Like a week ago I noticed my TC play wasnt recognizing my DLNA servers anymore. I think this update caused the issue (see also http://community.wd.com/t5/WD-TV-Play-Discussions/Unable-to-recognize-other-network-devices/m-p/608537#M1007)

Is there any way to revert to the old firmware?
