From included the ReadMe file: PS3 Custom Firmware v3.55 developed by Waninkoko


This Custom Firmware for the PS3 increases the system features of your console to allow the installation and execution of homebrew applications. This Custom Firmware could allow too the loading of legal copies (backups) using these new included features.

We don't support and condone the usage of illegal copies. We are not responsible for any damage for the usage of this Custom Firmware.


1. Download PS3 Firmware 3.55 (PS3UPDAT.PUP file).
2. Patch PS3UPDAT.PUP file with the patch included in this package using the "bsdiff" tool (
3. Install the patched PUP file like a normal firmware update. (in case you're already in 3.55 you need to install it in recovery mode).

How to install PS3 Backup Manager with Waninkoko CFW:

Below are some recent Tweets from Waninkoko: Custom Firmware v3.55 for PS3 released! Tools will be pushed in github soon.

Do NOT install in Slim consoles! Looks like users are reporting bricking issues. That's weird as the CFW was tested on both models.

Well... I don't know if those problems are real or just jokes. As I said, some testers tried this and worked in both models.

PUP MD5: 6eab7f1deea1ed46a1dc9924fd7080b3
PUP SHA1: 771e0f2431f15c7edd323899fbab810f32e35aba

IMPORTANT: Check the hash of the created PUP file before flashing.

I recommend updating first to OFW 3.55, then to CFW 3.55. I'm sorry for all the consoles that have dies, this was unexpected

At least some people report that it works! That's good news.

Working in an alternative way, with no brick risk... No ETA.

From Waninkoko CFW Analysis

  • nas_plugin.elf
  • lv2_kernel.elf
  • vsh.elf

From festizio on FIX PERMISSIONS: It seems that a lot of folks are having issues installing and running backups on there Ps3′s due to the bug in PL3 that effects file permissions. Here is what I have been doing to get around the black screen hangs and disc read errors.

1. fire up multiman, blackb0x, whatever ftp & transfer your backup
2. run your lv2 pkg of choice
3. run the fix permissions app that is installed from running the package located above

The app will go through the HD and correct the file permission errors that come with using PL3. I have been using this method after each game backup I install, however if you install (ftp/copy) 5 at a time the app only needs to be run once and it will fix all 5 games as it does its magic to the entire drive.
Now as far as USB, hampster driven HD's etc I can not say as I do not have any of the above so I have not tested it myself.

I'm on the same boat here. I don't think you can put your hdd in another ps3 without asking you to format it. We can't even take a backup on our pc now. Isn't there a tool that recognize the ps3 hdd now that developers know so much about how the ps3 work?

Hi Guys, anyone know if there is a simple ay of signing .pkg files as some of the games need .pkg files for install and they cannot be installed on this cfw cos i assume theyre not signed. would be handy if we could do this easily.

Should be fine its the nand in the ps3 thats people are saying has been badly written hence brick. Only prob you will have is when you put it in other machine it may ask you to format it.

Hi all, bricked one of my PS3's with this yesterday. Question for you all. If I take the hard drive out of that one and put it into my 3.55 OFW PS3 which is working fine will it do any harm to the working PS3? I want to try and transfer my Gran Turismo 5 save off the other hard drive to a memory stick.

To all, the (BR-Required) in Rogero is only a reminder that you can turn on so it tells you what games need a disc and ones that don't. It does not add any function to make a game work or not work.

You can downgrade from CFW the same way as OFW.

Anyone else notice the video in multiMAN and Rogero look choppy? Not the games them self but when navigating the menu the background changes are not as smooth as 3.41 JB?

I am able to play GT5 perfectly with the CFW, I was never able to get past the loading bar of the track selection. It took ages, the music shut off, just generally unplayable. Worked first time with GT5 unpatched this time.

Did you try using Rogero BM? I can't find any info on God of war 3 but maybe it need BR-Required to play, worth a try...

Load up Rogero and navigate to God of war 3, now you have to hit the square button (BR-Required), maybe the game requires any game disc to be in the PS3 for it to work, so after hitting the square button and enabling BR-Required, enter any PS3 game.

Then hit x to load the game, once again it sends you back to the XMB. Browse to the GAME tab. Rather than browsing down to ★/app_home/PS3_GAME, keep going and browse to the game disc, this will read as the game you want to load, not the game that is actually in.

Hope it works!!!

So i have brand new ps3 2504A, i had Geohot`s cfw, bluray working just fine,then i have installed OFW, then Waninkoko`s CFW. Everything was just fine. So then i run my God of war 3 it just freezes and send me back to XMB.

When i open the /app_home/ps3_game/ folder form CFW it says...

-An error occurred during start operation 80028F14

What to do ?! Try going back to OFW it reads that game is in the drive, but just black screen

Thanks but i tried with Rogero's BM already. The problem is i think downloads are for 3.41 / PSGroove / Dongles. One thing i note is when i open Rogero's BM, on right bottom side payload/version : kakaroto/3.55 Can this be a reason ?

I spend lot of time and not able to play any game as of now. Anywhere i can get original EBOOTs ?
