The PS3Xploit team, along with Joonie (of Rebug fame), have managed to make the PS3Xploit hack run on the latest PS3 firmware 4.84, through a clever modification of the official firmware.
It was disclosed when 4.83 was released that the underlying kernel hack was still alive, but the Webkit entry point had been patched by Sony’s official update. Typically, hackers would look for a new userland entry point to reactivate the hack. But this time the team chose to go another route, by reintroducing the exploit in a modified official firmware.
By installing that “hybrid” firmware 4.84 on your console (you’ll need to run 4.84 or less, which is obviously the case at the time of this writing since 4.84 is the most recent firmware on PS3), you are able to trigger the PS3Xploit and install the tools to hack your console.
Furthermore, Esc0rtd3w and Team PS3Xploit have already published updates to their series of tools so that you can be up and running right now on any PS3 console.
To restate, this new exploit is compatible with all PS3 consoles today (and until the next firmware update from Sony).
There are lots of benefits to installing this HFW (Hybrid FirmWare), as stated by the team:
1. You can use PSN since the FW is the latest.
2. You can downgrade/Install CFW on your PS3 if your model is downgrade-able/hack-able (excluding CECH-3K and 4K) (The same capability as what you had for 4.82 OFW)
3. You can use HAN and all the tools that worked up to 4.82 with this FW.
4. You can always go back to the real OFW 4.84 if you wish.
