: Like many Phison chips, the PS2251-09 uses a PRAM (Program RAM) architecture, meaning firmware is loaded from the NAND flash into RAM upon power-up. This makes it possible to "upgrade" or flash custom code if you have the correct Burner Image (the intermediate loader used to interface with the chip). Custom Firmware vs. Patching
Explain the to avoid bricking your drive during a flash update.
The PS2251-09 is one of the definitive modern platforms for researching this vector. Using tools like Phison-Build or community repositories on GitHub, researchers load patched firmware onto the PS2251-09 to alternate between standard mass storage and a malicious HID keyboard injector. Technical Guide: How to Flash the Patched Firmware
