This document provides a history of jailbreaking attempts for the PlayStation 3 from its earliest exploits to the current state. It discusses various jailbreaking methods and devices over time, including Geohot's work, the first jailbreak dongle, firmware updates from Sony that blocked exploits, and the work of fail0verflow, geohot, and others to find vulnerabilities in the system. The most recent goal mentioned is developing a jailbreak for firmware 4.21 that would provide full access and compatibility with online features and the PlayStation Store.

1. How to Jailbreak a PS3 on Firmware 4.25
PS3 Jailbreak The Story So Far
The Ps3's History is simply littered with old jailbreak solutions and fakes. We have seen
plenty attempts to get a working Playstation 3 Jailbreak. Early exploits depended on the
actual integrated Java of BlueRay menus. Unfortunately not a single thing was discovered
that allows you to run backups. At the same time the otheros option had been updated by
Sony to enable Linux on the console By running various tools on linux elements of the PS3
system can be investigated. Geohot made the earliest progress along with his memory
glitching solution to accessing the hypervisor. The community was outraged by what
happened next! Sony removed otheros swiftly in a move that many thought at first was an
April fools joke All hope seemed to be lost and the scene was getting much quieter again.
After getting the blame for otheros beign removed by sony Geohot leaves the scene.
Around august from nowhere a fresh PS3 Jailbreak dongle was reported. This was massive
news and was front page on the main sites within hours. News sites called fake on the video
at first. Quickly it became obvious that the dongle and backup manager were genuine. Even
at over 100 dollars all stores received many pre orders. The huge demand saw many people
without a dongle for weeks. During this time Sony rushed out a new firmware update. This
blocked unknown USB devices from working. This simple move stopped the dongle dead in
its tracks. The upside was that every game released to then would be playable from USB.
Without a firmware spoofer it was not impossible to go online with PSN. Many big game
releases for the coming christmas were going to require newer firmware. GT5 was out in
October and couldn’t be backed up. This required the new higher firmware to run
It wasn’t until nearly Christmas that a way was found to play it on CFW. By the end of
December failoverflow had shown the Key Fail to the world The fail in the key algorithm was

2. public news by the following day with the console security apparently beaten. New Years day
sees the hello world app by geohot being released Not long after that he released his
jailbreak pup. This one small pup file patched out the key checks enabling both homebew
and PSN access. A nice way to run backups was found with this jailbreak. Still the nicest
looking now! One infamous CFW from Wanikoto caused many bricks but most went for the
Keamw release.
For eight weeks users had backups and playing them online. Suddenly cheating was a real
problem with online games for the PS3 More server monitoring was added to the games to
catch the cheaters. It was around this time that unknown to Sony someone breached their
PSN servers. Credit card details were stolen from a possible 50 million users. When the hack
is discovered Sony closed down PSN. PS3 users were without PSN for nearly eight weeks.
A new pass key sign on process now prevented CFW users from accessing PSN. For the
average user accessing the network was too difficult. As new games come out they are
uplayable due to firmware restrictions.
Once more the PS3 scene started to go into limbo until a new dongle was released by true
blue. This shady company locked the eboots so they would only run with the dongle. Eboots
that were being released by paradox. A little later duplex started releasing PSN games
having somehow cracked the newer keys. How trueblue were decrypting newer games
remained a mystery for a while, that was until the 3.60 keys were leaked by an unknown
hacker. Rumors of a jailbreak for 3.60 OFW circulated along with various youtube videos. It
didnt take long though until Duplex turned their attention to the TB dongle itself. Within days
scene sites were filled with cracked TB Eboots meaning all the games previously only
available to TB users were perfectly playable. Promises were made by TB manufacturers of
a dongle update and newer games however nothing has been released so it would seem
now that trueblue are dead. Another big development to note is the new found ability to
convert from CEX to DEX. The great thing about a debug console is it can easily run any
homebrew without any keys at all. Debug units are tied to the Dev Network though so no
PSN for DEX users. The best way of course is to keep PSN and modify the latest firmware
so PS3 Jailbreak 4.21 is what is currently required. This would mean access to all the latest
game releases having the ability to play them online. Full access must also include for the

3. Store and being able to download and buy things is a must.
