An update to the PS3 system software was released on July 8, 2008. If you update your PS3 system, the system software version will be 2.41. In order to download PS3 system software version 2.41, you will need a minimum 135Mb of free space on either the PS3 Hard Disk Drive (System Update) or on removable storage media (PC Update).
With this update, we have fixed the problem that has prevented a limited number of PS3 systems from activating properly after updating to version 2.40, which was caused by certain system administrative data being contained in the HDD.
For those users who have updated to version 2.40 and have experienced the problem that the PS3 Home Menu (XMB) is not appearing, or no images are displaying on the screen, please contact Customer Service.
We have confirmed that for those users who have successfully updated to version 2.40 and are able to activate the PS3 system, this problem will not occur on your PS3.
We apologise for any inconvenience this may have caused you and appreciate for your understanding and continued support.
