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. :fire:

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. :love:

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. <3

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.

Patch Method by Barthen

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! :lovewins:

The method of external hard drive change does not look a bit suspicious ... that's something that with 2 accounts one main and one secondary can be done without problem
 
Guys, it seems that only few of you have really understood this news.

The point is simple: every game is "encrypted" with some keys.
Every firmware has some specific firmware-related keys.

A game "encrypted" with the keys of 5.01 firmware can't be decrypted/executed on a 4.05 console because of the "physical" lack of the needed keys.

A game that can't be decrypted/executed, can't be dumped.
So a 4.05 will never be able to dump a 5.01 game, and this is a fact.

What this news is talking about, is the possibility to:
  • take a dump made by a k-exploited console with 5.xx firmware, so that the game can be normally decrypted/executed and the dumper can do the dirt job;
  • edit the version of firmware requested by the game
  • repack the game as fake-pkg compatible with ps4hen.
This is a "simple" trick needed because simply dumping a game from a 5.xx console and repacking it, is not enough.

The point is that the hard part is to find a 5.xx k-exploited console.
Only the bigs of the PS4 scene own this type of stuff, and most of these bigs don't look good to backups (or that is the impression they give to us).

From my point of view, for now i prefer that a k-exploit for >4.05 firmware is not released, so that we can preserve these vulnerabilities for the future!

It's better that some "good souls" release only pre-decrypted dump of >4.05 games, so that they can enjoy this dumps on their 4.05 consoles without burning some potential exploits!

Just my 2 cents :D
