January 21, 2011 // 10:37 pm - Spanish PlayStation 3 developer Hermes has made available what he calls Hermes PS3 CFW, a PS3 Custom Firmware 3.41 version 1.0 Beta build which includes Payload 4, followed shortly by Hermes v4c Payload v1.01 which includes source code and details HERE.

Download: Hermes PS3 CFW 3.41 with Payload 4 / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP) / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP - Mirror #1) / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP - Mirror #2) / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP - Mirror #3) / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP - Mirror #4) / Hermes PS3 Custom Firmware 3.41 with Payload 4 (patched PUP - Mirror #5)

PUP MD5: 2787b1294ca0cd7064be099c53f3421f
PUP SHA1: 7ac5f852f74d74231316c2bb8f4b7cb91b048318

To quote, roughly translated: Well, do not take any more, I have to sleep it took more than 20 hours in active!

  • CECHC04 (my model, 3 times with Different Changes, FAT 60GB)
  • CECHG04 (FAT)
  • CECHH04 (FAT 40GB)
  • CECHL04 (FAT 80 gb)
  • CECHE01 (NTSC)
  • CECH2001A (NTSC slim 120GB)
  • CECH2004A (slim)
  • CECH2504B (slim)
  • CECH2404A (slim)
  • CECH2004B (slim)

I see that the link has been posted "tomorrow" will open a thread and it will take all this data update the readme. For those wondering, where you put the PS3UPDAT.PUP. bat of the package, run the bat and you create a CFW341_PS3UPDAT.PUP

That gets into a pendrive as PS3/UPDATE/PS3UPDAT.PUP and if you are in 3.41 so you will have to start the restoration console (which is done by pressing the power and using a USB cable for connecting the controller and such)

Then, since the firm installed just install the pkg is included and run the application to load the payload. I think that having a 100% success in all these models, we can say that the patch is safe: if a console peta, be anything else but work, work.

From the included ReadMe File: Hermes CFW 3.41 version 1.0 (BETA)

WARNING! This modified firware is tested only by two persons (it is experimental!!!) with this models:

  • CECHC04 (my model, 3 times with different changes)
  • CECHG04 (from one friend)

I cannot be sure if it can brick others models (don't use this CFW if you have buy your console with 3.50+, you can brick it!)

I am not responsible if this CFW brick you console: I have taken all possible precautions using SHA1 hash to avoid errors building the firmware, etc, and other problems (i include too my own patch utility to be sure you apply the patch correctly).

Building the firmaware:

Put original PS3UPDAT.PUP (3.41 v2) with patch.bat and run patch.bat. It must create CFW341_PS3UPDAT.PUP.

Put CFW341_PS3UPDAT.PUP as PS3UPDAT.PUP in one pendrive (usb:/PS3/UPDATE/PS3UPDAT.PUP) and try to update normally from the device.

If it say "you have this version yet" try the restoration - recovery method (pressing POWER. Ask about this method if you don't know in the forums)


  • LV1 patch for undocumented v1_undocumented_function_114 (kudos for flukes1/graf_chokolo) 1 byte, don't worry!
  • LV2 peek/poke patch (original from psgroove)
  • vsh.self patch to enable .self (same patch as psgroove-hermes_v4B. To launch self requires the payload working)
  • nas_plugin.sprx patch to enable packages (same patch as psgroove-hermes_v4B. You can install PSL1GHT original packages but requires geohot make_self_npdrm without one payload working)
  • category_game.xml modified to enable packages (kudos for KaKaRoTo)

With this options PS3 works with Homebrew signed (use make_self_npdrm in the EBOOT.BIN).


Install payloadhv4.pkg and launch it to load the psgroove-hermes_v4B

NOTE: payload code is experimental. I need to work in the application and the payload to add news features. don't worry about the source code now: this is a beta test version yet, but the source code will soon available.

I think i just wait a little bit longer to make sure i know what i am doing. I think i will eventually go from Hermes cfw 3.41-ofw 3.41-ofw 3.55 to Kmeaw 3.55 (in recovery mode). I let you know how it turned out. If you find anything on the subject, please post back. Thanks

same here I wanna update from Hermes 3.41 to Kmeaw CFW but am worried that the games I have installed already will be deleted or not playable, cuz 4 I installed using MultMan and they are located in ddev_hd/GAMES folder but the other 5 I installed using Comgenie and they are located in LAUNCH12345/GAMEZ folder.

Will do. Is there any known issues with missing bluray playback going from hermes cfw to kmeaw? I sure somebody must have done it before. Anyone?

I think I would use recovery mode to reinstall OFW 3.41 first, then go straight to Kmeaw 3.55 from there. After you get to Kmeaw can you test your Bluray playback and post back?

Do i need to take any special steps when going from Hermes cfw to kmeaw? Can i go straight to kmeaw in recovery mode or do i need to install ofw 3.55 first? Thanks for any reply.

ok just to double check, I'm on a Slim model 2001A so it passes, and I use iPod with PSGroove. So I can just install the CFW and everything will still be on my HD?

You will need Modified EBOOTs for both games or will need to update to a 3.55 CFW.

The XMB based payload won't help you unless you also install the CFW with it. I am using it on my slim that shipped with 3.40 and it works fine. I have also installed on a slim that shippem with 2.70 and a 80 GB fat, and both work fine. I would recommend that you install the CFW if you dont want to use your ipod anymore, but if you dont then maybe grab a teensy, they are easier to deal with.
