Phison Ps2251 07 Firmware Portable May 2026

Here’s a sample forum-style post about the Phison PS2251-07 (also known as PS2307) firmware. You can use this on places like USBDev, Reddit (r/techsupport, r/datarecovery), or MyDigitalLife.

Title: Need help with Phison PS2251-07 (PS2307) firmware – MP tool not detecting

Body:

Hey everyone,

I have a USB drive (Kingston/ADATA/Silicon Power – 64GB) that uses the Phison PS2251-07 controller (sometimes listed as PS2307). It suddenly stopped being recognized properly. Windows sees it as “Unknown Device” or 0MB capacity.

I’m trying to reflash the firmware using the Phison MP (Mass Production) tool, but I’m running into issues:

Questions:

  1. Which MP tool actually supports PS2251-07 properly? I keep getting “Device not support” or “Bin mismatch.”
  2. Where can I find the correct firmware .bin files for PS2251-07? Specifically looking for:
    • FW_07_01_80.bin
    • BD_07_01_80.bin
    • BootCode_07.bin
  3. Has anyone successfully recovered a PS2251-07? Any special pre-format or low-level steps?

Drive info before failure (from ChipGenius):
Controller: Phison PS2251-07 (PS2307)
Flash: Toshiba 19nm TLC (TC58TEG6TDLTA00)
VID/PID: 13FE / 5500

Any help is appreciated!

Optional extra tip to add after posting:

Important: PS2251-07 firmware is flash-type specific (e.g., Toshiba, Micron, Intel). Using the wrong firmware will brick it completely. Always check your flash ID before flashing. Also, some newer PS2251-07 drives are “ModeConverter” only – meaning you cannot fully reflash them with standard MP tools. If shorting pins doesn’t work, the NAND might be dead.
