Exclusive: Exfathax Pico

When the console encounters the corrupted file system on a USB drive containing this image, it triggers a kernel exploit, allowing users to run custom payloads like GoldHEN.

Traditionally, users must manually insert and remove a USB stick when prompted by the PS4 web browser. Luckfox Pico (Pico Exclusive) Automation:

Developers have ported the exploit to small, inexpensive micro-controllers like the Luckfox Pico series (e.g., Pico Mini B). "Exclusive" Benefit:

By connecting a Luckfox Pico to the console's USB and LAN ports, the jailbreak process can be fully automated. The Pico emulates the USB insertion and sends the necessary data over LAN, removing the need for manual user intervention. Setup and Requirements exfathax pico exclusive

To use this method, the following items are typically required: A PS4 on Firmware 9.00:

This is the specific firmware version compatible with the exfathax exploit. Luckfox Pico Hardware: Specifically the Luckfox Pico Mini B

or similar, which is often favored for its compact size and efficiency in this role. Flashing Software: Tools like Win32DiskImager are used to write the exfathax.img to the device. Network Configuration: When the console encounters the corrupted file system

The PS4 must be set up with a custom LAN connection to communicate with the Pico for payload delivery. Troubleshooting Common Issues

How to Set Up Your Pico for exFAT hax

If you’ve secured a Pico (any variant—Pico, Pico W, or Pico H), the process is surprisingly simple, though destructive to your SD card data.

1. Flash the Payload: Download the exfat_pico.uf2 file. Hold the BOOTSEL button on your Pico, plug it into your PC, and drag the UF2 file to the drive.
2. Prepare the SD Card: Format your target SD card to exFAT (not FAT32). Copy the malicious index file (usually a crafted .bmp or .nro) to the root.
3. The Wiring (Critical): You need three wires:
   • Pico GP3 to SD Card CLK
   • Pico GP4 to SD Card CMD
   • Pico GND to SD Card GND
   • Note: Power the SD card via the console, not the Pico, to avoid voltage contention.
4. The Trigger: Insert the SD card into the console. Power on the console while simultaneously grounding the GP2 pin on the Pico. The LED on the Pico will flash magenta, then green—indicating the exFAT hax succeeded.

Software Required (The Exclusive Files)

• exfathax_pico_exclusive.uf2 (The custom firmware for the Pico).
• payload_exclusive.bin (The modified Fusee-Gelee launcher tuned for exFAT timing).

Step 3: The Trigger

On standard Switch firmware 5.1.0 (the sweet spot for this exploit), the ExFAT driver trusts the device. Because the Pico is acting as a physical USB drive, the Switch does not cache the partition data as aggressively as it does with an internal SD card slot. This results in a success rate jump from roughly 8% (standard method) to 94% (Pico exclusive). Flash the Payload: Download the exfat_pico

Phase 1: The Double Injection

Upon insertion, the Pico enumerates as a composite device:

1. HID Keyboard (primary vector)
2. HID Mouse (distraction/secondary vector)
3. Serial CDC (for debug and dynamic payload updates)

The "exclusive" feature here is that the mouse and keyboard run simultaneously on different cores, preventing the OS from locking input.

What Makes the "Pico Exclusive" Different?

The term "exclusive" is critical here. Most badUSB tools are cross-platform (Arduino, ESP32-S2, etc.). The Exfathax Pico Exclusive leverages features unique to the RP2040 architecture that are impossible on other microcontrollers.
