Okay so I was searching up if there was a way to run SteamOS on a PS3 with Linux, and I came across something called OtherOS++. So I know it won't let me do what I want it to do, but what can it do? I used Google and only got tutorials, but not an explanation. What in user friendly terms is OtherOS++? Thanks! (BTW I have a CFW PS3)

Sony had an official Linux OS on PS3 called "OtherOS".
But when hackers found it could be used to exploit the console, Sony completely removed it (around firmware 3.40).

hackers re-added support and called it OtherOS++

Okay. So if I took the steps to installing this and got Linux running. Could I use my PS3 as a computer and run SteamOS?

As a computer, yes.
I read about SteamOS working on PS4's linux, but I don't know if SteamOS works on PS3's linux.
I never used it, so I don't know what it can do. sorry, can't help more here. Someone else will probably answer you.

Well I will check it out. In most forums people claim that it neither works on PS4 or PS3, but that was obviously proven wrong. Even if I can't manage to run SteamOS at least I have Linux. One last question if you can answer it, if I install OtherOS and get onto Rebug 4.30.2 (Supports OtherOS++) can I update or do I have to stay on that firmware forever? Which I am completely fine with. Sorry didn't see your edit. It's fine I will try it anyways. Thanks!

I installed OtherOS on my PS3 back in the day and recommend the Red Ribbon Linux distribution: http://weblog.redribbongnulinux.comxa.com/

Here's an old video I recorded showing off the operating system:


What Sony did by removing OtherOS was a very bad and evil thing. One of the reasons I originally purchased a PS3 was because I could install Linux on it! In fact, Sony got sued by the European government for the forced removal of this feature. The reason they removed it was due to Geohot glitching the PS3's hypervisor from OtherOS. Instead of putting a stop to opening up the system this spurred additional interest leading to the calculation of Sony's private keys by fail0verflow due to improper random seed generation in the ECDSA algorithm.

Steam for Linux only runs on x86/64 processors (PS3 run on PowerPC architecture). However for general use, as long as the software you need to run compiles for PowerPC, I suppose there is nothing preventing you from using it on your ps3.

Thanks! I will probably use Red Ribbon. What features do I have with this power now?

You have a full Linux distribution running on the Cell Broadband Engine with no hardware restrictions from the hypervisor. You can program multi-core code to take advantage of the synergistic processing units of the Cell and have full access to the GPU. Other than that, you can pretty much do anything you'd normally do on Linux as long as you can build the source for PowerPC. Back when I was recording this video, I had actually installed OpenOffice (before the LibreOffice fork) and was using it as my primary PC to do homework while I waited for my laptop to get back from RMA.

I also recommend using the latest Rebug firmware and switching your kernel to DEX so you can use real time debugging tools in GameOS if you want to mess around with native homebrew and/or game hacking. The PS3 is pretty well documented due to the nature of attack (complete code signing bypass) and is a great platform to hack on even though it's starting to show it's age. I highly recommend doing some research and learning about the PS3 security measures and exploits. It's a fun rabbit hole to fall down if you're into this sorta thing. :)

Wait.After I install otheros++ I can update to the latest/other Rebug Firmware? Doesn't it have to be made OtherOS++ or can I just do it?
BTW you just confused the shit out of me. Can I run Linux while playing PS3 to run DEX tools?

I am also considering installing OtherOS(++) onto my PS3.
Relys' video looks wonderful; I can definitely see a really good use for Linux on a PS3! :)

However, I just wanted to ask whether I need to be on a specific CFW and whether I need to have either a CEX/DEX to use the setup/installation tools.

I had just formatted my PS3 via the recovery menu a few minutes ago for the setup tools, then I installed Setup_flash_for_OtherOS.pkg via the Package Manager, but when I booted the tool I encountered a 80010017 (error during start operation) error.

Currently, I am running 4.80 Rebug CEX firmware, and this is why I asked if I needed a specific CFW and type to successfully use the tools and get the beeping sound to tell me it's all worked out.

Any help would be massively appreciated

Yes. You need Rebug 3.55.2 OtherOS++ PS3UPDAT.PUP. Search it up. It is a Rebug downgrader made to support OtherOS++. P.S there are others that you can search up if you prefer them. I will not provide and links.

Sorry, I wasn't too sure on what to use; I did happen to do a search, but I was searching for video tutorials at the time, and they weren't really specifying what CFW and firmware to use for some reason. :wink: (and that is definitely not me being a dumb person; I am actually a person with common sense that just happened to have a lack of information with me at the time...)
