The Pico is programmed to immediately push the pOOBs4 exploit upon detection, launching the payload launcher on port 9020 without manual intervention. 3. Space-Efficient Design

However, based on the components of the name, this likely refers to a specialized project involving file system support for the Raspberry Pi Pico (or a similar RP2040-based microcontroller).
The 9.00 firmware jailbreak relies on a kernel heap overflow vulnerability triggered by a corrupted . Under normal circumstances, users must manually insert a specially formatted USB flash drive into their PS4 exactly when prompted by the web browser exploit.
Plug the Pico into your PC via its USB cable, then release the BOOTSEL button. The computer will detect it as a mass storage device named RPI-RP2 .
Exfathax is the name given to the kernel exploit for PlayStation 4 consoles running firmware version 9.00. Discovered by the developer ChendoChap (in his GitHub repository pOOBs4 ), this exploit targets a vulnerability in how the PS4’s kernel handles a malformed file system on a USB drive.
: Running the "GoldHEN" homebrew enabler, which is the final payload delivered by the exfathax exploit to unlock features like game backups and debug settings.
When the ChendoChap pOOBs4 kernel exploit revolutionized the PS4 scene, it came with a frustrating caveat: users had to manually plug and unplug a specially formatted exfathax.img USB drive every single time they booted their console. An "exfathax pico exclusive" configuration solves this headache completely, using an affordable microcontroller to programmatically trigger the exploit. The Evolution of the pOOBs4 Exploit
