150w ago - 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.
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)
CECHH04 (FAT 40GB)
CECHL04 (FAT 80 gb)
CECHH01 (NTSC 40GB FAT)
CECH2001A (NTSC slim 120GB)
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.

Add another model to the list. CECH-2512B (Slim/320GB/Hong Kong) Upgraded from 3.40 that came as default using the Recovery Console. No issues so far. I already loaded the 1.01 Payload. Everything is working as it should. Thanks a lot.
Better backup, format & install the CFW. But you can try this way too. Just don't forget to report back.
I'm on ofw 3.41 & use an ipod 1st gen with hermes 4 for jb for all my games,I do not really want to install custom firmware but can I just only install the payload package under normal jb conditions & then no longer use my ipod for jb just using payload menu on screen?
If I can & dosn't really work for me can I just delete & will I be back able to jb with ipod?
