PS3 JailBreak for 3.50 and lower

Posted by Ali Reda | Posted in | Posted on 6/26/2011

You must be on 3.41 or below to jailbreak with the PSGroove exploit (DO NOT update beyond this if you want to use this or similar exploits). You can downgrade from firmware version 3.50 or earlier by entering factory/service mode and using .self and .pup files which you can download

PSFreedom was written by KaKaRoTo to implement the original PS Jailbreak exploit, based in part on reverse engineering efforts by the PSGroove project.

How It Works?

The initial analysis by suggested that it was a Stack overflow attack. After further analist it turns out that this exploit is a Heap Overflow attack. The exploit carefully manipulates the heap by plugging and unplugging fake usb devices with large device descriptors until the device on port 4 which misreports its size to overwrite one of malloc's boundary tag.
1) plug device 1 then device 2 then device 3
2) After port three is connected, port two will be disconnected, this will cause the port two descriptors to be freed, which frees up some space between the Port One and Port Three descriptors.The heap is now prepared for our exploit.

Jailbreak PS3 on 3.55

A new hacker team called fail0verflow was able to find a new way to jailbreak PS3, the team was able to make a small presentation at the Chaos Communication Congress which has been held in Berlin recently. The hackers team announced that they had been able to break PS security in a missive way.

Fail0verflow discovered how to calculate the security keys needed to sign off on any piece of software which essentially makes the keys to the security gate for the PS public.
Now, this prodigy hacker Geohot has released PS 3 Root Keys publicly on his own site beside thanking the fail0verflow team. He also encouraged them to contact him if they want their “next console to be secure”. From now on, developers can make their own applications, custom firmwares or even pirated ISOs without facing any kind of problems
