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 for one haven't updated my launch PS3 because of this bricking problem.

Of course if you're talking about re-flashing the nand with a nand flashing tool, that's not very "joe public" friendly and would need specific skills. If however you've fixed yours using a JB device of any kind, or any other method that is easily done i think you should share the details.

Anyway, here's hoping you tell all.

Confirmed. Uncharted 2 works on my PS3 with no issues and no freezes at all

Well I have helped do a few console's phat and slim and haven't run into any issues using this CFW at all. But with regards to all the older phat model's bricking up is the only reason I stated it was not a good idea. In the coming months there will be way more CFW out there than these.

These are just the beginning. Now that we have such CFW it's a matter of time until we have an actual "no worries" CFW out in our hacker ocean

All MFWs apart from Kakaratoks are potentially dangerous and carry a risk. I would really advise people not to play with a modified or actual custom firmware without the right form of flash programmer.

I can understand people been excited, but you do all realise you don't need to bypass security anymore? Give it a couple of months and you won't need any peek and poke or system patches at all.

I know, I haven't had the time, I'll give it a try again and let you know.

Well the system won't let me edit the post so I replied to myself. It's just if it has been confirmed it's only lvl2 that has been shafted then this should be fixable. I'm trying to get hold of a bricked console right now to confirm that right now.

Thanks for your reply. Before using Wanin CFW, with PS3Break in 3.41, I had no problems with this games. More people reported random freezes, and Dean who made Multiman suggested me to install Kmeaw CFW.

It's fully compatible with the nem Multiman version, and according to other people resolved the freezing in these games.

You my friend do not update to CFW on that console. You mines well pull out a hammer and smash your PS3 and it would be more useful. Try a different CFW man. There are others that have been released that would be safer for you to go with than Waninkoko's.

That is weird. Have you tried to re-install it and see if it does the same?

Hey I updated my console last night to run the CFW but I have an issue with distorted sound, all the sound xmb, game and any streamed stuff is sounding well off. Has anyone else had this, I've had a quick scan through the posts on this thread and couldn't find any mention. Oh and I reverted back to OFW and the sound works fine... Strange ey??

Is it true it only messes up the lvl2.self on them, or does it also mess with metldr or the keyvault?
