PS3 Firmware Spoofing drawing on early PSP hacks for reference

[horendus]

Something that could potential grind the PS3 hacking scene to a hault is the current inability to spoof the firmware, which would be needed to allow future PS3 games to run on a PS3 3.41 system.

Firmware spoofing came out very early in the PSP hacking scene as games quicky came out requiring newer firmwares than that which had been hacked yet.

The PSP and PS3 both run similar OS's, I assume it was originally created for the PS3 then modifed heavily for the PSP.

I guess the question which needs to be answered is, is the same OS vulnerability used to Firmware Spoof the PSP present in the PS3?

Or was this patched on the PS3 once it was used on the PSP?

Or did it only ever exist on the PSPs version of the OS?

Or did sony infact not bother patching the PS3s potential vanurability because the PS3 was considered Hack Poof, leaving this exploit open for use once again?


Someone who understands the PSP firmware spoof hack or someone who can "reverse Engineer" the PSP firmware spoof hacks should check to see if the same vanurability exits on the PS3.

I have an original PSP with an early PSP firmware hack installed into the custom OS available for use...

Please discuss

The problem with that is the psp guru left a long time ago. No 1 has seen dark alex In ages in the psp scene has not been the same for a very long time. the architecture of the disc construction maybe someone similar I keep in mind the psp does ron on cell processors in the full security system from the ps3 has it been exploited. n as of right now we only have 1 game that requires a higher firmware so it seems a little patience is in order as the ps3 is a totally new beast as compared to its a little brother the psp. Strides have already been made To successfully load the flash from a usb stick. Now we need rights to overwrite the nand itself. They were all com In due time I assure you Compare the xbox 360 scene to the ps2 scene. It has matured much quickly and revs seem eager to share with us meager end users. For that im thankful and the homebrew keeps me entertained in the mean time.

i dont think people should worry about this so soon it has only been a couple of days since we even found out that a game needed 3.42 also those games arent in everyones hands yet. give it time the scene is moving very quickly. im sure we will see a way to play the games within the next week or two.

The problem is that the file that stores the encryption information is encrypted (index.dat). Now if we could decrypt it, we can do more then firmware spoofing. All the executables are encrypted too. Once we have the decryption key(s), we can decrypt everything and make modifications to the OS. We can enable debug options, enable otheros, and who knows what. The main problem is getting the decryption keys. I don't know how the PSP guys did it, but it may be something along the lines of tricking the PSP to hand out the keys or something. Or maybe the PSP's keys are short and could be brute forced. But to get the PS3's decryption keys, I'm guessing it would be alot harder, as they built an enormous security system in it. Maybe it's impossible to do from lv2, so we need the old 3.15 exploit to trick the system into giving out the keys. (Just speculation).

Jesus people, paragraphs! (Not including the OP)

It's giving me a headache just looking at these posts.

Workarounds like the old PSP spoof won't work on PS3 OS because it uses smarter checks than the PSP did. Though I'm sure it's been said in one of the blocks of text above my post.
