advanced ps3 jailbreak
I don't know why people keep developing jailbreaks that you have to UPGRADE to. I can only get a jailbreak on 3.55 but oh damn I have a 4.40 console. I really don't like hardware mods because If it breaks your pretty much ****ed as apposed to a software mod you can recover just by reformatting. what is the point of a downgrader anyway? I mean I might as well get a damn mod chip to directly let me play backups on my ps3. now don't get me wrong i'm not saying it is easy but I just wonder why people keep building on an exploit that died long ago and don't work on finding new exploits. if anyone feels the same please respond.
Because you need the private keys to be able to install CFW on OFW 3.56+ and nobody has them.
CFW can only be installed on OFW 3.55.
You can install a "mod chip" aka ODE (3k3y) to play backups, but having CFW is more flexible because you don't need to keep the "mod chip" installed, you just use it to downgrade and then take it out. Also, you cannot run homebrew with an ODE.
The Cobra ODE is like the 3k3y and is yet to be released. They say it will support 3k and 4k models but this is yet to be confirmed.
The reason there's doubt is because you need the console specific root key to be able to use an ODE and right now, the root key can only be extracted on 3.55 CFW. 3k and 4k models cannot be downgraded to 3.55 so the root key cannot be extracted.
This is the reason the Cobra ODE has been delayed, it's because they cannot find a way to extract the root key on FW higher than 3.55 yet. When (and if) they do, it's another story.
