Overview

Have you ever imagined turning your PlayStation 5 into a fully functional Linux PC capable of running Steam games? Thanks to the work of security engineer Andy Nguyen and his ps5-linux-boot project, this is now a reality – but only for certain PS5 models running specific firmware versions. This guide will walk you through the entire process, from understanding the prerequisites to booting Ubuntu and launching your favorite Steam titles. The exploit leverages a patched hypervisor vulnerability, granting Linux direct access to the console's powerful hardware: eight Zen 2 CPU cores (16 threads), a custom RDNA 2 GPU, and 16 GB of GDDR6 RAM. However, please note that this is entirely unofficial and not supported by Sony. Proceed at your own risk.

Prerequisites

Before you begin, ensure you have the following:

• PS5 Console: Only the original "Phat" model (disc or digital) is compatible. Slim or Pro versions are not supported.
• Firmware Version: Your console must be on firmware 3.xx or 4.xx. If you have updated beyond 4.xx, this exploit will not work.
• USB Drive: At least 16 GB capacity for the boot image and Linux installation.
• ps5-linux-boot Files: Download the latest release from the project's GitHub repository.
• Ubuntu ISO: A desktop image of Ubuntu (20.04 LTS or later is recommended).
• Patience: The process involves multiple steps and potential pitfalls.

Step-by-Step Instructions

1. Prepare the USB Drive

First, format your USB drive as FAT32. Then, copy the contents of the ps5-linux-boot release onto the drive. Next, extract the Ubuntu ISO and place the files in the root of the USB, overwriting any conflicting files. Alternatively, you can use a tool like Rufus to create a bootable Ubuntu USB, but the ps5-linux-boot files must be added afterward.

Note: The exact file structure is critical. Ensure the USB contains both the Linux kernel (vmlinuz), initrd, and the bootloader configuration from ps5-linux-boot.

2. Disable Automatic Updates

To prevent your PS5 from updating to a newer firmware (which would break compatibility), go to Settings > System > System Software > Automatic Downloads and disable system updates. Better yet, keep your console offline until you're ready to run the exploit.

3. Boot into Safe Mode

Power off your PS5 completely. Then press and hold the power button until you hear two beeps (about 7 seconds). Connect the USB drive to the console, then connect the controller via USB cable. Select Clear Cache and Rebuild Database from the Safe Mode menu. This step is optional but can help avoid conflicts.

4. Launch the Exploit

After rebuilding the database, the PS5 will restart. When you see the main menu, insert the USB drive again (if not already plugged in). Navigate to Settings > System Software Update and select Update from USB Storage Device. The console will read the ps5-linux-boot payload and load the Linux kernel. If successful, you'll see a boot menu with options to launch Linux.

5. Install Ubuntu

The boot process will eventually lead you to the Ubuntu live environment. From there, double-click the Install Ubuntu icon. Choose your language, configure partitions (you can use the entire internal SSD or an external drive), and complete the installation. Once finished, reboot – but do not remove the USB drive yet.

6. First Boot into Ubuntu

After installation, the system will boot into Ubuntu directly from the internal SSD (if you installed it there). You'll need to log in with the credentials you set during installation. Now, open a terminal and run the following commands to update the system and install essential drivers:

sudo apt update && sudo apt upgrade -y

Also install the proprietary GPU drivers (if available) or rely on open-source alternatives.

7. Install Steam

Ubuntu's default package manager might not include the latest Steam version. The easiest way is to download the .deb package from the Steam website and install it with sudo dpkg -i steam_latest.deb. Resolve missing dependencies with sudo apt --fix-broken install. Launch Steam from the application menu, log in, and begin downloading your games.

Common Mistakes

• Wrong firmware version: The exploit only works on 3.xx and 4.xx. Do not update past 4.xx.
• Incorrect USB preparation: The ps5-linux-boot files must be at the root, not in a subfolder. Missing the kernel or initrd will cause boot failure.
• Forgetting to disable updates: An automatic system update will patch the vulnerability, making the exploit useless.
• Using a non-Phat model: PS5 Slim or Pro have different hardware and are not supported.
• Skipping Safe Mode: While not always required, some users report better reliability after rebuilding the database.
• Not backing up data: The process can corrupt your SSD if something goes wrong. Back up your PS5 saves and games beforehand.

Summary

Running Linux on a PlayStation 5 is a fascinating hack that unlocks the console's hardware for a true PC gaming experience. The ps5-linux-boot project by Andy Nguyen makes it possible, but only on original PS5 models with firmware 3.xx or 4.xx. By following this guide, you can boot Ubuntu, install Steam, and play games natively. Remember the risks: this voids warranties, may be patched by Sony at any time, and could lead to bricking if not done carefully. However, for adventurous users, it's a rewarding way to repurpose a console into a powerful Linux desktop.
