Finally a CFW for the PS3 with backup support! DO AT OWN RISK!!

Waninkoko won’t have you waiting any longer… The infamous hacker in black dishes a full serving of PS3 custom (or modified) firmware; and by full serving I mean all your homebrew, including support for Backup Manager! That’s what you’ve been asking for, right?

How to install PS3 Custom Firmware v3.55

1. Download PS3 Firmware Update (OFW) 3.55
2. Install (or restore) OFW 3.55
3. Patch the OFW 3.55 PS3UPDAT.PUP using “bsdiff” / “bspatch”

   bspatch PS3UPDAT.PUP PS3UPDAT-CFW.PUP CFW_v3.55.patch

4. Confirm the resulting PUP has the md5 sum of 6eab7f1deea1ed46a1dc9924fd7080b3
5. Rename and copy the patched PUP to a USB storage device: /PS3/UPDATE/PS3UPDAT.PUP
6. Flash it from Settings -> System Update (or the Recovery Menu if you need to)

Tools will be available on github soon. See README.txt for more info.

Update: Uh oh… Waninkoko speaks up: “Do NOT install in Slim consoles! Looks like users are reporting bricking issues. That’s weird as the CFW was tested on both models.”

I’m testing it now. Please standby.

Update: Well, on my Slim the installation went a-okay! That said I’ve uploaded the patched PUP for you. And I can also confirm that multiMAN, as a Backup Manager, works with no problem. I should mention I updated from geohot’s jailbreak; I already had multiMAN installed under that (for those wondering why it won’t install under Waninkoko’s CFW).

Update: There have been many brick reports… Some fat models, some slim… Many variables come into play when patching LV2. So right now, it’s like this: If you really, really want backups, then give it a shot, just know the risks involved — you could end up with nothing in the end. Otherwise I recommend you buy your games and jailbreak only for homebrew purposes.

Update: As the reports file in, it would seem older “Fat” (launch?) models are more prone to bricking. If you have one of those, I reckon you not try this at all. Slim owners — this doesn’t mean you’re in the clear either. While mine worked, your luck may differ.
