PC Update
Visit http://eu.playstation.com for the very latest version of the update data. Follow the on-screen instructions to download to your PC.
To transfer the update data to your PLAYSTATION 3, save the file to a PS3 compatible storage device such as Memory Stick, Memory Stick Duo, USB drive or PSP.
Before starting, use your PC to create a folder named 'PS3' on the storage media or USB device. Within the folder, create a folder named 'UPDATE' (This folder name is case sensitive and must appear in all capital letters). Once the UPDATE folder has been created, download the PS3 system software update to this location.
Once the update data has been saved, disconnect the storage device and connect it to your PS3 via the slots under the slot cover or the USB connectors depending on the device you're using.
Once connected, navigate to Settings on the PS3 Home Menu, select [System Update] and then [Update via Storage Media]. Select the connected device and your PS3 will install the update data stored there.
