Set the New VID and PID values if you wish to change them, or leave them at default to match the original factory settings.

It is impossible to discuss the PS2251-07 firmware tool without mentioning . Because this specific Phison controller has an exposed microcontroller architecture, security researchers discovered that its firmware can be overwritten to mimic a USB human interface device (HID)—like a keyboard.

Click the button (usually a gear icon or a tab labeled "Parameter"). It will prompt you for a password. Enter the default password: The tool will update the firmware and display a progress bar

Watch the progress bar carefully. The box color will shift during processing.

When finished, the icon will turn and say "Finished" or "Pass."

A user can "push" a new firmware image into the controller's RAM and then burn it to the flash memory.

The primary function of the Phison PS2251-07 Firmware Update Tool is to interact with the controller at a low level. Unlike a standard file transfer, which operates at the application level, this tool communicates directly with the hardware. Its most common use case is mass production or "mass production mode" (often accessible via the MPTool software). This allows technicians to configure specific parameters of the drive, such as adjusting the partition type, setting write-protect flags, or calibrating the drive for specific types of NAND flash memory.
