How to jailbreak a PS4 using PPPwn

How someone could jailbreak your PlayStation 4 using PPPwn

This tutorial covers using PPPwn on Linux and installing GoldHEN on a PS4.

Part 1: Using PPPwn on Linux

PPPwn is a kernel remote code execution exploit for PlayStation 4 up to FW 11.00. The code bellow is a modified proof-of-concept exploit for CVE-2006-4304 that was reported to PlayStation. This section will guide you through the installation and usage of PPPwn on a Linux system.

Prerequisites

Before you begin, ensure you have the following:

A Linux distribution (e.g., Ubuntu, Debian, Fedora)
Root or sudo privileges
Basic knowledge of networking and Linux
A PlayStation 4 on firmware version 9.00 or 11.00

Installation

Step 1: Update Your System & Install Dependencies

First, update your system's package list and upgrade any outdated packages. Then install python3 and gcc.

sudo apt update
sudo apt upgrade
sudo apt install -y git python3 gcc

Step 2: Clone the PPPwn Repository

Next, clone the PPPwn repository from GitHub.

git clone --recursive https://github.com/TheOfficialFloW/PPPwn
cd PPPwn

Step 3: Install Python Dependencies

Install the required Python packages using pip.

sudo pip install -r requirements.txt

Step 4: Compile the stage1 .bin

make -C stage1 FW=YOURFWVERSION clean && make -C stage1 FW=1100

Replace the YOURFWVERSION with your PS4's version (Example: 1100, 900...).

Setting up GoldHen

Now you need to go to https://github.com/GoldHEN/GoldHEN/releases and click on Assets at the latest pre-release & click download.

Step 2: Extract the .bin from the archive

After you've downloaded the .7z file Here's an example, go to the pppwn_stage2 folder and select the .bin that matches your firmware. Then move the .bin and rename it to .../PPPwn/stage2/stage2.bin.

Step 3: Move the goldhen.bin file to a USB stick

In the archive, you will find a file, named goldhen.bin, which you will have to move to a exFAT formatted USB stick, into it's root directory.

Run the final commands!

Now you will need to do the following on your PS4:

Connect an Ethernet cable from your PC to your PS4
Go to Settings and then Network
Select Set Up Internet connection and choose Use a LAN Cable
Choose Custom setup and choose PPPoE for IP Address Settings
Enter anything for PPPoE User ID and PPPoE Password
Choose Automatic for DNS Settings and MTU Settings
Choose Do Not Use for Proxy Server

After you did all of that, press the Test Internet Connection button and run the following command at the same time:

sudo python3 pppwn.py --interface=YOURINTERFACE --fw=YOURFWVERSION

Change the YOURINTERFACE with your network interface (example: eth0) and enter your firmware version.

ALWAYS wait for the console to show the message "Cannot connect to network: (NW-31274-7)" before trying this PPPOE injection again.
