How to Jailbreak a PS5 on Firmware 4.03 or Lower

Jailbreaking your PS5 can unlock new features like running homebrew applications and accessing hidden debug settings. This guide will show you how to jailbreak a PS5 on firmware 4.03 or lower. If your PS5 is on a firmware version lower than 4.03, don’t worry—you can safely update to 4.03 using a USB drive. It’s important to avoid updating via the internet, as that could install the latest firmware, which might not be jailbreakable.

What You’ll Need

PS5 console with firmware 4.03 or lower.
USB drive with at least 1GB of free space.
Stable internet connection (for downloading the necessary files, not for updating the firmware).

Step 1: Check Your Current Firmware Version

First, you need to check which firmware version your PS5 is currently running.

Go to Settings > System > System Software > Console Information to view your firmware version.

If your firmware version is lower than 4.03, proceed to the next step. If you’re already on 4.03, skip to Step 6.

Step 2: Backup Your Data

Before jailbreaking, back up your PS5 data to avoid any potential loss.

Go to Settings > System > System Software > Back Up and Restore and follow the instructions to back up your data.

Step 3: Disable Automatic Updates

Before we begin, it’s crucial to prevent your PS5 from automatically updating to a newer firmware. Follow these steps:

Go to Settings > System > System Software > System Software Update and Settings.
Turn off Download Update Files Automatically and Install Update Files Automatically.

Step 4: Set Up DNS to Access the Exploit Page

To run the jailbreak exploit, you’ll need to adjust your network settings:

Go to Settings > Network > Set Up Internet Connection.
Choose your connection and select Advanced Settings.
Set the Primary DNS to 192.241.221.79 and Secondary DNS to 165.227.83.145.
Save your settings. This will allow you to open the web browser via the PS5’s User Guide menu.

Step 5: Prepare Your USB Drive

You’ll need a USB drive formatted to exFAT to transfer files. Here’s how to prepare it:

Connect your USB drive to the PS5.
Go to Settings > Storage and select your USB drive.
Choose USB Extended Storage > Format as exFAT.Tip: If the PS5 doesn’t recognize your USB in the front port, try using a port on the back.

Step 6: Updating to Firmware 4.03 (For Users on Lower Firmware)

If your PS5 is on a firmware lower than 4.03, you’ll need to update it using a USB drive. Do NOT update via the internet, or it will install the latest firmware, which isn’t jailbreakable.

Download the 4.03 firmware.
Format your USB to exFAT, if you haven’t already.
Create the following folders on the USB: PS5 > UPDATE.
Place the downloaded firmware file into the UPDATE folder and name it PS5UPDATE.PUP.
Plug the USB into the PS5.
Go to Settings > System > System Software > System Software Update and Settings.
Select Update from USB Drive. (Tip: If the PS5 doesn’t read the USB from the front port, try the back one).

Step 7: Running the Exploit to Jailbreak the PS5

Now that your PS5 is on firmware 4.03, let’s run the jailbreak exploit and unlock Debug Settings:

On your PS5, go to Settings > User Guide > User Guide.
The Al-Azif Exploit Page will automatically open.
Press L2 twice to open the URL entry field.
Type https://es7in1.site and press enter.
On the website, select PS5 from the top menu.
Click Sleirsgoevy 4.03 Bin JBV2.
Choose the JB+KSTUFF option. This will run the jailbreak exploit and inject the fPKG enabler payload. (Note: This process may take multiple tries to succeed (anywhere from 1 to 10 attempts). Be patient and repeat the steps if needed.)

Step 8: Verify the Jailbreak and Enable Debug Settings

Once the exploit has successfully run:

Press the PS button on your controller to return to the main screen.
Go to Settings and scroll down.
If you see Debug Settings, the jailbreak was successful!

What’s Next?

Your PS5 is now jailbroken, and you’ve unlocked Debug Settings. With this, you can run homebrew applications and tweak settings, but be aware that updating your firmware will remove the jailbreak. Be sure to avoid any future updates if you want to maintain your jailbreak.
