Instead of using a physical flash drive, developers started using Single Board Computers (SBCs) like the , ESP32-S2 , and specifically, the Luckfox Pico , to emulate the USB drive.
The "exclusive" magic lies in its automation. A developer created a port of the pOOBs4 exploit, known as , which gives the board a "brain". This allows the Luckfox Pico to manage the entire exfathax process automatically:

The traditional USB stick method for PS4 9.00 is functional but clunky. It relies on precise human timing and risks the failure of the exploit due to late insertion. Instead of using a physical flash drive, developers
Optimized for modern SD cards that come pre-formatted with ExFAT, eliminating the need to force-format them to FAT32 using third-party tools.

The PS4 9.00 jailbreak relies on a filesystem bug discovered by comparing the differences between the 9.00 and 9.03 kernels. The vulnerability is triggered when the console mounts a drive containing a corrupted or heavily modified exFAT filesystem layer. This allows the Luckfox Pico to manage the
