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.

MultiMAN 1.13.04
HERMES v4b CFW for 3.41
v4b patcher

CECH-2101B (slim 250gb) (very easy, very stable)

From OFW 3.41 to CFW HERMES 3.41

I used the pre-patched file found in the first post and everything is working flawlessly. No crashing, no nothing. Very clean install from regular update on the XMB choosing to install from storage devise instead of network. All PSN games working, all pre-patched eboot games working from external and internal as if nothing had changed. Very happy I installed HERMES, very happy I didn't try others.

Can't connect to PSN, I meant to say that everything was working 100% as it was before, with the dongle.

For the last 2 guys: You need to install the hermes v4 under "install packages".. once.

Then every time you start up (whether it be hard or soft boot) you will need to run the hermes program under games.
It's nice not having to hard power the PS3 anymore too, especially with the slim.

That Hermes is the payload for jailbreak. You need this to run the backup manager. Thanks, It is what is on the dongles.

And as far as i know that you can not connect to the PSN with 3.41. This is to take away the need for the doogle. Thanks

With Payload 4 ? Does this mean, that the hermes modification for playing without disc (broken drive) is integrated in this CFW ??

benefit to this over the 3.55 CFw's is that everything that worked before just works now. PSN, games with fixes (disgaea 3)... I'll move up to a higher CFW in the future but for now. THANKS HERMES!!! for letting me ditch the dongle!

blackbox ftp works normally, which it doesn't on 3.55 (right?)

Ummm... You can CONNECT to PSN? How?

successfully installed on fat ps3 60 gig. all 3.41 emulators working, all backup managers working-15 games tested including NFS hot persuit and GT5 with 3.41 eboot patch, all psn debug games working , signed and unsigned pkgs for 3.41 working. very easy to install and use.

just turn on ps3 after installation of patched PUP, install payload pkg and run it. no need for any usb. better than any 3.55 CFW (if you don't use psn) because there is no need to run any lv2 or fix permissions pkg.
