As Play Station 4 owners are currently beta testing the major update 3.00, Sony has released the latest Play Station 3 firmware update, 4.76.
Head to Settings, then System Settings and finally System Information.
If the number showing matches the update you downloaded at the beginning of the guide, then the update was successful :) If you have any questions or comments please post them in our Play Station 3 Discussion Forum.
Follow the on screen instructions to begin the update.
When the update is done, your PS3 will reboot and when you come back, confirm you have the firmware update.
From there, plug in your flash drive or insert your memory card.
