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.

1. every game I have, runs from internal
2. I did not. I did it all from XMB
3. Mine got a little fooked up, but follow my post and it works, which leads me to believe its not a perm broke.(as your ps3 is alrdy JB'd, back up your /dev_flash3 files for a restore later)
4. Dunno, I dont have a slim. I would assume if you have the smalle NAND you would be ok. (16mg vs 256)
5. 3.41 sign'd and 3.55 Un-sign'd run from what I understand. I could not get 3.55 sign'd to run
6. No one would know that as that havent banned anyone as of yet.

The only conclusion of the same model brickin is that they did something wrong in the install process.

I didnt have to use recovery - I installed from 3.50ofw->3.55ofw->3.55Wan fw

This makes no sense... There should be NO differences in different model PS3's? Can somebody tell me how on earth it works on one's model PS3 but not another? Sounds like whoever made this poorly patched LV2...

Oh and just saw the Recovery Install? How can somebody release something so risky like this? Maybe this is just a way to buy bricked ps3's off people for cheap. jk

Well, its also up to your ps3 model and more but anyway. I can also confirm some freezes here and there. Most of the time while leaving xmb to multiman. Or within a gamestart.

Sometimes i can power of on the console but most of the time i have to hard reset with powercord. Also im presented with a harddrive database error. That fixes fast and after that it runs fine again but its weired for sure.

I need to figure out if there is any difference in updating through xmb against the recovery mode?! Does anyone else had some freezing issues or something like that??

Yes, it fixes the whole dev_hdd0, but it doesn't affect games which are working. I remember that evilsperm edit the original fix_permissions (fixed only LAUN12345) to fix the dev_hdd0.

All slim moddels have been reported working 100% the bricks from slims were because of people patching the update wrong! And if multiman isn't working for you try deleting the previous save game files and game utility data from xmb or reformat the hdd and update to ofw to geo to wanin then back up and try again and it should work... I tested this method just now!

this killed my ps3, it was working fine and throughout the day it froze more and more often until the ps3 was growling and failing to do anything... this will kill your ps3 fat or slim, stay away and go to the ofw; such a shame after backing-up my games just to not be able to use them... last time i trust this user.

Does that fix the whole hddo folders? Will this affect already running games to not run after fix?
