How to Bypass PFS Protection PlayStation 4 Tutorial by Zecoxao

Today PlayStation 4 developer zecoxao shared a PS4 tutorial on how to bypass Sony PFS (PlayStation File System) protection entirely with other devs... check it out below!

To quote: How to "bypass" pfs protection entirely

Things needed:

• PS4 on 1.76
• Disc game or PSN game activated on the console
• TITLE ID of the Game in question
• http://www.extreme-modding.de/PS4/1.76/Playground/index.html (the FTP Server + Debug Settings part)
• FTP client (filezilla or something like that)
• Brains you can use

How to:

1- Go to http://www.extreme-modding.de/PS4/1.76/Playground/index.html and select the FTP Server (big Silver Star)
2- Enable it and minimize the browser
3- Start the game you want to copy/modify pfs content
4- Keep the game running (i believe this is the issue people are having)
5- Start your favourite ftp client
6- Navigate to:

/mnt/sandbox/pfsmnt/[TITLE-ID]-app0

where [TITLE-ID] is the id of the game you're running.
7- From there you can dump and modify files at will

I originally wondered if there was a way to do pfs bypass with the app.db so i asked around to see what would people say. Credits to flatz for the original idea.

PS:

/mnt/sandbox/pfsmnt/[TITLE-ID]-app0-nest

contains the entire file listing (and also the files) in a big .dat file. You can also use it but you'll need an extractor later.

Now the eboot.bin protection is left to "crack". let's see how this plays out.

Thanks to @B7U3 C50SS for the news in the Shoutbox!

This is using sandbox as you can see in the commandline
(/mnt/sandbox/pfsmnt/[TITLE-ID]-app0)

So what exactly is the point in this? Can anyone confirm if the files are not encrypted like the article suggests?

According to the article they are but we are not using this (ram access) is the best for any if this stuff.

On another site it gives details on it n how well it works but our main guy is away for the weekend n taking personal time with his family.
