The most iconic question for newcomers we probably heard after buying their own PS3 console is how to jailbreak it, so that they can get the best out of their PS3 as well as enjoying cool homebrew applications such as multiMAN, emulators and not to mention unlocking a much better Linux with the 3.55 CFW. Well, that’s what I’m going to write in this tutorial where will give my best to help guide those newbies who are still finding their own ways to give custom firmware (CFW) a shot on their console.
Why 3.55 CFW and not other PS3 firmware version? The 3.55 is currently the highest version of firmware which is jailbreak-able and thus helping in some ways for the overall PS3 games compatibility. You might not want to mess with 3.41 firmware, for example, which you need to edit some inner files to get some games working.
Rebug 3.55 CFW

Before we started with the tutorial, you need to know what type of 3.55 CFW you want for your console. If you are the advanced type, always like to alter things here and there to unlock features, then you might want give Rebug 3.55 CFW a try. It’s currently one of it’s kind where jailbreak users can taste Debug Settings options right on the PS3 XMB menu, not all of them are “playable” in the CFW though. In addition, there are also some other features such as Package Manager and Rebug Selector which sets them apart to other region of 3.55 custom firmwares.

Now, if you are the “clean” type and doesn’t want your console to be butt loaded with some unnecessary rubbish functions, then Kmeaw 3.55 CFW is the best choice as far as my opinion goes. There has been no problems or issues such as bricked PS3 consoles after installation reported so far despite it’s the only 3.55 custom firmware release from kmeaw. You can compare that with Waninkoko who has two versions of his 3.55 CFW been released where the first version has bricked a lot of consoles back in January. Alright, enough with the talk, let’s proceed to the installation of the custom firmware file (PUP) on PS3.
The 3.55 CFW Tutorial
- With the discussion over the two type of CFW, you may have gotten the idea which custom firmware is the best for your console. Have one in mind? Now, pick between these two CFW files which you need to download before we can go to the next part of the tutorial: Download Rebug 3.55 CFW (PUP) or Kmeaw 3.55 CFW (PUP)
- As you have downloaded the CFW of your choice, you need to properly install it on your PS3 console. To do that, put the PUP file onto your USB flash drive with the folder path type being set like this one here “x:PS3UPDATEPS3UPDAT.PUP”. Remember, the folders and file name need to be set exactly like what i have shown just now so that you can update your firmware successfully, x: being your USB flash drive root, if you still not get it.
- After you have been assured that you have followed the steps above correctly, now you just need to connect your USB flash drive to your PS3 console so that it can read the PUP file you transferred.
- On the PS3 XMB menu, you need to go to the Settings where you can find “System Update” feature just like in the screenshot below.

- Then, your PS3 will boot up two options, Update via Internet and Update via Storage Media. You must choose the later because you don’t want your console to download the latest firmware which is yet to be jailbreak (at the time of the writing) aren’t you?

- Afterwards, you just need to follow the on screen instructions until you have successfully installed 3.55 CFW into your precious PS3. It’s that easy right? Well, enjoy your freedom
That should wrap it up, if you have any questions or problems when jailbreaking your PS3, you can shoot me up. I will try my best to help in any way i can. Oh, and if your PS3 console is already on firmware higher than the 3.55 version, i am sorry to say that you are out of luck because there is no method yet available in the scene to downgrade 3.56, 3.60 and 3.61 PS3 firmware to 3.55 CFW.
