Is any genuine cfw for PS3 4.00 out yet?
This is my first post on this site. I apologize in advance for sounding like a dummy, but I am new at this.
I have recently bought a 160GB slim PS3 (about 3 months back, but its warranty is now void since I moved to India). Currently, it has v4.00 firmware on it, but it was shipped with v3.65 (verified with MiniVerChk). Since I was new, I was foolish enough to upgrade the firmware to v4.00 at the time. I have bought Resistance 3 game, but somehow, a crack started developing at the centre of the disc, and I have noticed that the crack grows the more I play the game, and I'm afraid the disc might just shatter into pieces someday. It plays fine as of now, but I want to be able to copy the game onto my ps3 int hdd and play it from there. I am not a fan of playing ps3 online, so that's not a concern if that facility gets disabled after jailbreak.
There are a few too many sites which offer jailbreak cfw for 4.00, but then, there also lots which say that these cfw's are fake. I can't seem to tell who's right and who's not.
Now, I wish to know:-
(1) Is there any stable and genuine cfw for 4.00 yet, using which I can backup and play my game from the int hdd?
(2) If not, is there a way to downgrade my ps3 firmware and then jailbreak it to achieve my purpose?
Thanks in advance. Cheers!!!
