PS4 EBOOT / ELF FW Patcher Barthen Method, Playable Scene Group

To kick things off on this Valentine's Day hot on the heels of recent PS4 scene group MarvTM comes news via Malatya of another known as Playable, who is also doing PS4 4.05 PKG releases including The_Last_of_US_Remastered_EUR_FW_405_PS4-Playable... and even DUPLEX is now doing 4.05-friendly PS4 releases including Uncharted.4.A.Thiefs.End.PS4-DUPLEX.

Next up, @CelesteBlue passed along a Pastebin guide via Twitter from Barthen on how to lower the firmware requirement in ELF and PRX files which can be found below.

Following that method and the Free PS2 Pub Gen / Fake PKG Tools releases, PlayStation 4 developer @cfwprophet shared some updates on Twitter including Fake_PKG_Tools_v1.3.rar and an ELF FW Patcher v1.0 which patches the Firmware Version hex number of one or more PS4 ELF files for those working on getting newer titles running on 4.05 OFW.

From Barthen: How to lower the firmware requirement in ELF and PRX files

Example of lowering the firmware required for files compiled with the leaked 4.50 *** (tested on 4.05) hex editing some bytes:

1. In the ELF section called "sce_process_param" we patch the reversed *** version (there should only be one instance of the pattern): search for "01 81 50 04" and replace with "31 80 50 03"

2. In the ELF section called "sceversion" we patch the *** version (multiple instances of the pattern will be found): search for "04 50 81 01" and replace with "03 50 80 31"

3. Resign it with flatz's make_fself.py or add it to a PKG with cfwprophet's Fake_PKG_Generator

4. Profit

5. A side effect of this is that if someone is able to dump games on higher firmwares (ex. 5.05) it SHOULD be possible to play those games in lower firmwares (ex 4.05) with this method, unless the games uses functionality added on newer ***s

From the ReadMe.txt: ELF FW Patcher v1.

• Select one or more Files or a Folder to patch.
• Enter FW version hex numbers into the to Lookup Text Field.
• Enter FW version hex numbers into the to Patch Text Field.
• Click Patch FW Button.

Status Strip is currently broken......need to invoke it. I'll ix that later.

Have Fun -cfwprpht-

Here's a video via @toni1988 from Cyb3r on YouTube, with a rough translation as follows:

We already have the clear sign that there is something forceful in PS4 firmware 5.05 where it looks like can massively launch games from a USB external storage disk. Still better than in 4.05. Everyone's question is when will the release be? We will not be able to prove it but if it comes out we will have to update.

Finally, @Bassabov shared a Horizon Zero Dawn Russian Video Demo (a translation would be great) alongside another via @GritNGrind from kbarticle for those interested.

Thanks to @bonusball, @kizabg, @Orgad, @sdlc, @spyro2670 and @ziobleed for the news tips in the PSXHAX Shoutbox today, and enjoy your Valentine's Day everyone!

Nope

Iso files give you access to all files containing the game, All these files can be manually modified as far as the licence is concerned, and finally using this new tool.

Why not?

 

[AeonLewis]

Cmon, just release the PS4 Console Master Key instead of teasing us

One of you out there probably have it already

 

[boybergamo76]

Guys i discovered more informations, we needs first of all a spoof for higher firmware for 4.05, this is the base of everything.

 

[n30j0su3]

thats exciting! the PS4 scene is running!!!

 

[boybergamo76]

i know how this was done, we need spoof to higher firmware over 4.05, without spoof we can't do nothing!

The game can be dumped from a 4.05 console ^_^

 

[Havok10]

All the packages on the 'net are encrypted disc dumps. They have been dumping these forever with the hope that we can use them in the future. That future is not here yet.

As has been stated numerous times you need a kexploit for a higher firmware to dump a higher than 4.05 game.

 

[gamba66]

First of all im not sure if I believe the rumours about horizon zero dawn, but if it is out there it will be just a matter of time until it leaks.

Second: cfwprophet indirectly mentioned he will create something to patch the 4.05 kernel to spoof a higher firmware

I am sure he will be releasing a payload pretty soon

Then game can be dumped directly in 4.05

 

[Havok10]

Spoofing does not give you the valid decryption keys.

 

[tooretoo42]

Spoofing should permit to install game with retail disk > 4.05 and also official updates > 4.05 and after that allow dumps for copy private.
