- Today PlayStation 3 developer KaKaRoToKS
has released the first PS3 Custom Firmware alongside a video of it in action below!
PlayStation 3 Custom Firmware, users can now run PS3 homebrew 3.55 signed packages (currently doesn't support PS3 game back-ups) via 'Install Package Files' on non-JailBroken PS3 consoles and access PSN for the moment.
(Removed app_home from XMB) / PS3UPDAT.355Cfw.KaKaRoTo-1.2.pup
(More game_tool2.xml Fixes) / PS3UPDAT.355Cfw.KaKaRoTo-1.2.pup
(Mirror) / PS3UPDAT.341Cfw.KaKaRoTo-1.2.pup
(Fixes Missing Game Data XMB Icons) / PS3UPDAT.355Cfw.KaKaRoTo.pup
(Mirror) / PS3UPDAT.341Cfw.KaKaRoTo.pup
(Mirror) / PS3 Category Game XMLs
/ PS3 Keys
/ PS3Keys GIT
Note: DO NOT try to install this from the service mode, it might brick your console, install it normally from the normal menu or the recovery menu. Regarding PS3 back-ups with CFW, from IRC: the payload currently remaps the Blu-ray to USB or internal if a back-up manager calls for it meaning don't expect support for them unless someone else adds it.
has now updated FWTool
for PS3 Firmware (not application) PKG files and it now decrypts, encrypts and signs properly.
To quote from his site: Great news! Thanks to the tools made by the fail0verflow team (and thanks to sven in particular for his work on the pkg/unpkg tools), the first “Custom Firmware” is now available for the PS3!
I see a lot of questions coming up really fast on my Twitter account, so here are the basic things you need to know :
Because of legal/copyright issues, I will not provide the custom firmware to anyone, however, I’ve made available all the tools necessary to transform an Official firmware update, into a custom one, just grab my ps3utils repository from github, compile, then run :
./create_cfw.sh PS3UPDATE.PUP CFW.PUP
This will take the official firmware, unpack it, modify it, then repack it correctly (requires you to install ps3tools).
This requires Linux of course, but I’m sure others will do it for the masses and illegally release those files somewhere.
The advantage here is that you can do it for any firmware, if you want to keep version 3.41, then give it the 3.41 update, if you are on 3.55 already and can’t downgrade, then run the script on the official 3.55 firmware and it will create a modified 3.55 firmware.
You can put the file in a USB drive under the filename “PS3/UPDATE/PS3UPDAT.PUP” and then go to system update in the XMB, and it will allow you to install the update (even if you’re already on 3.55).
People are asking what are the features of this firmware, it’s simple, all it does is to add those “Install Package Files” options to the Game section of the XMB. It doesn’t do anything else!
This firmware will not allow you to run the currently available homebrew application. Once the homebrew developers re-package their files in a ‘retail’ .pkg format with signed executable, then it will work (this should be coming soon thanks to the work of the fail0verflow team).
Since the kernel is left unmodified, this means that this custom firmware is really meant for future homebrew installation, and it will not allow piracy. I plan on keeping it that way.
This is just the first attempt at custom firmware, and it only contains a minor modification to allow you to install pkg files directly, eventually we’ll get some more options added to it in the future. This is just starting to get interesting!
p.s: Thanks to everyone who helped make this possible!
1. Download ps3 utilities and ps3 tools from github / team fail0verflow:
git clone https://github.com/kakaroto/ps3utils.git
git clone git://git.fail0verflow.com/ps3tools.git
cp pkg unpkg ../ps3utils
2. Grab the PS3 encryption/decryption/signing keys from github:
git clone https://github.com/kakaroto/ps3keys.git
3. Download PS3 3.55 (or whatever official firmware PUP)
4. Extract and copy “PS3UPDAT.PUP” to the “ps3utils” directory
5. Create the PS3 Custom Firmware (CFW) from the original/official update (OFW):
./create_cfw.sh PS3UPDAT.PUP CFW.PUP
6. Copy and rename CFW.PUP to a USB storage device keeping this directory structure in mind: /PS3/UPDATE/PS3UPDAT.PUP
7. Connect that USB device to your PS3 and install from Settings -> System Update
If you’re currently running 3.41 (or earlier) you can either remain there and create a specific CFW PUP for that version, or you can upgrade to a later PS3 firmware version, like 3.55 for example. It’s whatever original PUP file you use — only you cannot flash a version lower than the current version installed on your PS3.
So if you’re already at 3.55, where you’re unable to downgrade, then for the moment you have no other choice but CFW (or OFW) 3.55. 3.41 on the other hand: upgrade or create CFW 3.41 and for the interim you’re still able to jailbreak and run unsigned homebrew. Other things to note:
1. This CFW does not modify the kernel in any way, meaning all the current compiled homebrew out there will not install or run using “Install Package Files” from the XMB.
2. With the above point in mind you should know this CFW does not enable backups - straight homebrew.
3. Current PS3 homebrew and new homebrew will need to be “retail” packaged and signed; that’ll happen with fail0verflow's tools.
4. This is only the beginning.
