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 need some help. I installed Waninkoko 3.55 firmware and Rogero v7.8 and now game discs don't show up in XMB. I know its not the drive b/c I can run BR movies fine and the disc shows up in Rogero. Any help? Thanks in advance.

Strange but now everytime I put a disc in the game shows up in /app_home/PS3_game

Is this normal behavior?

This particular one is suicide with the wrong hardware, but they're all still bloody dangerous if they patch any system binaries, especially with the way the PS3 boots. But I think the Wii has also proven that it doesn't even need to be a binary to cause major problems either. My point really was that just because this works for some people and the others seem to work for everyone, it doesn't mean it's a safe method.

Or even a good idea, but that is a matter of opinion. People are working on things. Some methods have already been released, even if they have limited success. Then they can choose to use a MFW, people are free to make their own choices. But I just thought people should be aware that even if it seems to work fine on 100% of consoles there's still a risk because the method itself can not be 100% safe.

To nick a phrase, you can have it done right, fast, or cheap. Pick two. Fair enough, but what about all those dumb people who are bricked because Waninkoko himself told them Slims will break but Fats are fine?

yes 256MB NAND consoles reportedly will brick if flashed with Waninkoko CFW3.55 but no bricking report as of yet when flashed with Kmeaw CFW 3.55 and lv2.pkg... To be on a safe side don't flash your console if your not sure about it.

So i'm assuming all 256mb NAND consoles that are ofw 3.55 are totally closed off from the homebrew scene at the moment? Downgrading firmware causes losing blu-ray, and installing any of the working CFWs that permit backup manager will always result in a brick?

I've flashed 2 CECH-2002A PS3 model yesterday and backup all of my ps3 games to the internal HDD and external HDD. I can confirmed that burnout paradise, killzone 2, castlevania lords of shadow, GT5, Black Ops, Street fighter 4 and bad company 2 works with rogero manager 7.8

Its dangerous if you do it to the wrong hardware sure, I'm not denying that - but how could you possibly know whats going to happen in a few months, and what if you don't want to wait a few months for this magical solution that may or may not come?

Theres nothing wrong with CFW's if you're not dumb enough to apply it to incompatible hardware.
