taufik, Thanks! However, according to your link say 4.25t03.55pup CFW downgrade but my friend is at the 4.55 FW and PS3 SLIM with 120GB or 320GB - Not sure.
misiozol, LOL! As I said he have 4.55 fw since he updated it but dont know if he had 3.55 fw for the first time before update to 4.55 or much later fw version.
For what I know is that he have 4.55 FW that he updated by mistake and he have 120gb or 320gb. Not sure.
