It is very easy to jailbreak your PlayStation Three
To jailbreak the PS3 is a process by which a system bug is exploited allowing a level of access to the subsystem which makes it possible to replace the authorized factory firmware with a customized firmware created by the hacker community. Advantages to running a custom firmware amount to increased capability, backup ability, and control over the system beyond what Sony would otherwise allow. One particular benefit is the ability to install an entire game from the Bluray so that disc insertion is no longer required to play a game. This way those precious and expensive game discs can be stored away safely, preventing scratches and damage, while all your games are accessible directly from the system drive or an attached USB storage device.
It is very easy to jailbreak your PlayStation 3 if you have not used the system update to advance to a version higher than OFW 3.55. You do not need to buy any special devices to jailbreak your PlayStation, or pay for any special software. Everything you need is free to download. Also have ready a USB Flash Drive and PC, those you may buy or barrow.
There are different Custom Firmware (CFW) available. Rogero is a very popular CFW and is completely free. Rebug is also very popular. Last we knew, Kmeaw firmware is no longer being developed. Many feel that a CFW is a better option as opposed to an Optical Drive Emulator. Our guide focuses on applying the Rogero CFW.
If you have a PlayStation 3 with a firmware version newer/higher than 3.55 it is still possible to jailbreak it, but it is a lot more involved and does require the purchase of hardware. To Update Rogero PS3 Custom Firmware on a PS3 with factory firmware 3.55 or older, and for a PS3 that is already running Rogero custom firmware, the process is straightforward and noninvasive.
