I'm new to the ps3 since i bought mine today so i thought it would be a good thing to register here. I'm familiar with almost every hack on every platforms except for the ps3.
Hope i won't need your help and if you need mine be welcome.
To answer your question, you can't without downgrading first. If you need more help ask in the appropriate section and the users here will answer your questions.
Just Joined I want to hopefully find a trusted rep to flash my PS3, any help in the right direction would be most appreciated. I hear Musy409 does downgrades?
