The guide can also be followed for the purpose of applying jailbreak to a PS3 that still has official factory firmware 3.55 or older. This guide covers, specifically, the process of upgrading a PS3 that has already jailbreak applied, and is using the Rogero custom firmware.
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. 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. Our guide focuses on applying the Rogero CFW. Many feel that a CFW is a better option as opposed to an Optical Drive Emulator. Last we knew, Kmeaw firmware is no longer being developed.
Rogero is a very popular CFW and is completely free. There are different Custom Firmware (CFW) available. Also have ready a USB Flash Drive and PC, those you may buy or barrow. You do not need to buy any special devices to jailbreak your PlayStation, or pay for any special software. 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. 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.
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. Advantages to running a custom firmware amount to increased capability, backup ability, and control over the system beyond what Sony would otherwise allow. 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. The Regero firmware is used on the PS3 after jailbreak. Rogero (pseudonym) is a well known Playstation 3 (PS3) developer that offers, free of charge, a CFW (Custom Firmware) having the same name. Both can be considered an upgrade, as a PS3 with OFW being converted to a PS3 with Rogero CFW is an upgrade as well as a PS3 which already has Rogero CFW needing updated to a newer CFW. The process for a fresh install is the same as for an upgrade and use of the terms is really just semantics.
