Users report problems with PS4 update 2.04

New firmware for the PS4 is available, and it's (imaginatively) called 2.04. It's focused solely on stability, and is supposed to make the overall service more solid, and it doesn't add any new features. The update has also caused a few problems regarding error messages ("SU-30709-9" or "CE-32937-4"), as some users have reported. They cannot access the service and/or download the update. Sony has confirmed via Twitter that they know about the problem.
