only old model will have a firmware bellow 3.55 (like PhatPS3, or slim up to the PSMove Demo disc pack, released near September 2010)
If on of these console have a firmware past 3.55, there's a way to downgrade them using a hardware NOR/NAND flasher (but it requires soldering skills).

Newer consoles can't be downgraded at all.

You will have more chance to buy a used PS3 already hacked than finding a new one on an old firmware.



@ankc:
Backups used to depend on the firmware you used. New games had new encryption key which required patches to play on old console firmware.
But it's now possible to install a custom firmware at the same version than the latest official firmware (4.30/4.31) so the games don't need patches anymore.

If a game is not working, it's because it's incompatible with the gameManager and/or launch method.
You can see a list of backup compatibility here: http://www.pshomebrew.net/wiki/PS3_Backup_Compatibility_List

Some game haven't been tested yet.
Other games are marked as not working, but it might be an old report because there's no precision on which cfw/Manager it was tested on.
Hi Cyan

thanks for your answer :)

as you said it is possible to install CFW 4.30/4.31 but the current guide is based on CFW 3.55 and I heard here and there that 3.55 is the best as you might not be able to downgrade above it(unless you use an E3 flasher). so how do I play the newer games if I want to stick to 3.55?

Thanks

There are different way to play new games requiring a higher firmware:

1. install a CFW equal or higher (there's no big sticky tutorial to update to 4.x on gbatemp, but it's still evolving. Someone might write one once it's easier/more straightforward to install).
It's not hard to do if you really want to update, and you can downgrade without hardware flasher if you followed the guides correctly (you need to start at 3.55 to add a debug menu to allow software downgrade later, then update and the debug menu will still be there)

2. Wait for someone (usually released groups) to release a patch/fix for the game to work on older firmware (usually 3.40+). The file are decrypted and re-signed for 3.40

3. Do the above patching yourself. You need the 4.x keys and a program to decrypt the files, then sign them with the known private 3.40/3.55keys
Then when you launch a game from a higher firmware, multiMAN ask you if you want to patch the file setting for that game (PARAM.SFO) which contains the required firmware version. it will replace the value "4.x" by "3.40" (you can even to it manually in your computer, but multiMAN does it for you).

Recent games have another firmware version check directly into the executable in addition to the PARAM.SFO file.
but new version of multiMAN can patch it too.

Thanks clears things up :)

Have a virgin 4.31 slim PS3 here I'm looking to install CFW on.
Which version(s) out there are safe to use?
I find a couple when I google search but none are on sites I trust (like this one), any tips for me?

EDIT: The one from ps3jail.com seems to be the one most people say is working, even on OFW 4.31.
Can anyone confirm?

EDIT2: And now I find that the "CFW" from ps3jail.com is actually just the OFW so now CFW at all :/

You cannot install CFW on virgin (OFW) 4.31, period.

What is your Slim model? Depending on the model you can buy and use E3 Flasher to downgrade to 3.55 and go on from there.

Seems like my only 2 viable options are:
1: Wait until 4.31 possibly gets hacked
2: Use an E3 flasher
And option 2 is the more likely one, expensive stuff thou :)

I wouldn't recommend a youtube tutorial (in general), and even less when it's only showing the TV screen all the time without future supports and better explanations. but, it's up to the user to decide if he wants to take the risk to follow a random video which is not even made for what he is looking for.
That video is initially for GeoHot Custom Firmware 3.55, some CFW can be installed like that, and other might require the recovery menu.

I have a phat ps3 so my understanding is that it is hack able. I am wondering though if there are downsides to hacking, would I be blocked from psn or online play? I have playstation plus so that is a deal breaker.

no you won't be blocked from playing online, you only need to stay on the most recent cfw or have a spoofer.

So it looks like the hardware to downgrade the PS3 to a hackable firmware is pretty expensive.

Couldn't I just use 3k3y?

Can someone please create a more updated guide? I'm entirely new to this and I'd rather not use files and methods from 4 years ago.
