A significant new discovery is circulating in the homebrew development community: the Y2JB (PS5 YouTube App Jailbreak) project. This exploit, currently in beta development, has reached a major milestone: code execution in Userland on the PlayStation 5.

What is Userland?

Simply put, Userland is a privileged, but not top-tier, execution environment. Being able to run code here is a crucial step toward homebrew development, potentially more comprehensive jailbreaks in the future, and greater control over the system, potentially paving the way for emulators, game backups, and unofficial applications.

Y2JB Key Requirements

In order to work, the Y2JB exploit requires very specific conditions:

  • YouTube App Version 1.03 PKG: It’s essential to have this exact version of the YouTube app installed. Different or updated versions will most likely not work.
  • FTP access to the path download0: You need to be able to FTP access a specific folder on your PS5 system  download0. Often, writing to this path requires changing permissions.

Setup Instructions (Experimental)

If you meet the requirements and want to test in a controlled environment, the steps to follow are:

  1. App Installation: Make sure you have the YouTube app version 1.03 PKG installed on your PS5.
  2. FTP Access: Use an FTP client to connect to the console and navigate to the path  download0.
  3. Permissions: You may need to change the folder permissions  download0 to make it writable.
  4. Internet Disconnection:  Important Note: Disable your PS5’s internet connection to prevent the file splash.html (crucial to the exploit) from being overwritten or automatically repaired by Sony’s servers.

Status and Important Notes

It is essential to underline the current status of the project:

  • UNSTABLE BETA: Y2JB is in a very early beta stage and suffers from instability issues. Crashes are frequent and reliability is low.
  • NOT for End Users: This exploit is absolutely not ready for general consumer use. It is a tool for researchers and developers.
  • Risk of Future Blocking: As with any exploit, Sony could patch it with the next system firmware update, rendering it unusable.
