PS3 4.45 firmware update bricks consoles

Angry users claim main navigation screen inaccessible after latest update

Sony’s latest PlayStation 3 firmware update 4.45 has caused a number of consoles to stop working.
A number of users took to the Sony support forums to report the issues, such as the disappearance of the main user interface screen.

One user said that their system would also not shut down properly, and was forced to pull the out the power plug to turn off the console. It has been suggested that starting up the console again results in the same problems.
Sony has since confirmed it is aware of the problem and has pulled the update while it conducts an investigation and implements a fix.
