PS5 Y2JB Guide – Everything You Need to Know (November 2025)

PS5 Y2JB is a userland exploit that uses a vulnerability in the YouTube app to run remote JavaScript.

It allows you to run unauthorised code on specific firmware versions of the PlayStation 5 by using the YouTube application. 

It is not a full “jailbreak” and does not grant kernel-level access, meaning it has limited functionality. 

What Y2JB Exploit Achieves

Userland code execution: The Y2JB exploit allows for remote JavaScript to be executed through the PS5’s YouTube application. This provides developers with a user-level entry point into the system.

Payload loader: Developers can now use a payload loader to send custom files to the PS5. This is a critical step for further development toward a full jailbreak.

Not a full Jailbreak: It is crucial to understand that Y2JB is not a complete jailbreak. A full jailbreak requires a separate kernel exploit to gain higher-level permissions. 

Researchers hope to combine the Y2JB userland exploit with a future kernel exploit, such as the “Lapse” exploit, to achieve a full jailbreak

Check your Firmware: This exploit only works on specific PS5 firmware versions. Your console cannot have the latest update, so if you have already updated, this method will not work.

You can check your system’s current firmware by going to Settings > System > System Software > Console Information.

YouTube App Version: You must have the YouTube app version 1.03 installed on your PS5.

Network Setup: The process requires setting up a custom DNS address or restoring a backup from a USB drive.

Exploit is in beta: The Y2JB exploit is in a beta state and is considered unstable. It is intended for developers and researchers, not for general users.

Risks: Any type of exploit or modification to your console’s software carries risks, including bricking the system, voiding your warranty, or having your account banned by Sony. Proceed at your own risk.

Y2JB Installation via System Backup (Non-Jailbroken PS5) 

This method involves restoring a backup file containing the necessary exploit to your console. This will factory reset your PS5, so back up your data beforehand. 

  • Download the backup file from a reputable source, such as the official GitHub page for the Y2JB project.
  • Format a USB drive to exFAT or FAT32.
  • Transfer the backup file to the USB drive.
  • Restore the backup on your PS5 using the official Sony backup and restore process.
  • Your PS5 will then contain the necessary files for the YouTube exploit.  
  • Load exploit: Launch the YouTube app to load the remote JavaScript loader and begin sending payloads

Y2JB Installation via FTP (already Jailbroken PS5) 

This method is for users who already have some form of jailbreak or code execution capabilities on their PS5.

  • Install the YouTube app version 1.03 on your PS5. You will likely need to download the PKG file for this specific version from an external source and install it on your PS5.
  • Access your console via FTP. You will need to use an FTP client on your computer, like FileZilla.
  • Transfer Files. Connect to your console and navigate to the path /user/download/PPSA01650. If the folder doesn’t exist, create it.
  • Send the necessary files, such as download0.dat, from the Y2JB releases page into that folder via FTP. 
  • Send Payloads: After loading the exploit on your PS5 through the YouTube app, use a remote JS loader or other tool to send payloads to your console. 

How to Use Exploit:

  • Launch the YouTube app on your PS5.
  • The exploit will load automatically.
  •  It will show a “remote JavaScript loader” message.
  • Wait for Payloads. This exploit prepares your console to accept payloads. 
  • However, users need to wait for further developments and payload releases from the community.

That is a complete guide on PS5 Y2JB and how to use it.
