I have saw a couple of post asking how to unjailbreak your PS3 so I thought I would make a TuT explaining how.

1.Download the original 3.55 update here. [ Register or Signin to view external links. ]

2.Create a folder on a usb title PS3

3.Then inside the PS3 folder make another folder UPDATE.

4.Then take the original 3.55 Firmware that you downloaded and put it in the UPDATE folder.

5.Take the usb and put it in your PS3 and go to system updates and update via. storage device.

6.Download the update and there you go your PS3 is no longer jailbroken.

*NOTE* I would recommend deleting all homebrew as well as clearing your boot_history.dat a TuT telling you how to do that can be found here. How To Delete boot_history.dat
