Phison Ps2251-07-ps2307- [2021] -

The Phison PS2251-07 (also known as PS2307) is a high-speed USB 3.0-to-Flash microcontroller chip widely used in consumer flash drives, including models from Kingston (like the DataTraveler G4) and Toshiba.

Depending on your goal, you are likely looking for information related to one of the following areas: 1. Device Repair and Restoration

If your drive is showing "Write Protected," "0 MB capacity," or is otherwise inaccessible, you can often restore it using specific production tools.

MPALL (Multi-Port ALL-in-one): This is the primary factory-level tool for Phison controllers. Versions like MPALL v3.70.0E and v3.72.0B are generally compatible with the PS2251-07.

UPTool: An alternative tool often used if MPALL fails to recognize the drive. It performs a deeper "low-level" format, though it may result in lower final read/write speeds.

Format & Restore Tool: A simpler Phison Restore Utility for end-users that can sometimes fix basic file system corruption without complex firmware flashing. 2. Firmware Flashing

Flashing firmware is risky and can "brick" the device if the wrong version is used.

Burner Files (BN):* These are temporary loaders (e.g., BN07*.BIN) used to communicate with the chip during the flashing process.

Firmware Files (FW):* These are the actual operating instructions for the controller (e.g., FW07*.BIN).

Resources: Documentation and downloads for these files are most commonly found on specialized community sites like USBDev.ru. 3. Security and "BadUSB" Projects

The PS2251-07 is popular in the cybersecurity community because its firmware can be modified to emulate a keyboard (HID), allowing it to execute automated scripts—a technique often called a Rubber Ducky attack. Phison Format & Restore v3.26.0.0 - USBDev.ru Phison Ps2251-07-ps2307-

View topic - Need help reviving Kingston DataTraveler 3.0 USB – PS2251-7. HDD GURU FORUMS Phison PS2251-07 (PS2307) Firmware [BN07*.BIN, FW07*.BIN]

It looks like you’re referencing a Phison PS2251-07 (often labeled PS2307) USB flash drive controller. This is a very common controller found in many USB 3.0/3.1 flash drives from brands like Kingston, Corsair, Patriot, and ADATA.

Below is a draft quick-reference guide for identifying, low-level formatting, and recovering these drives.

Typical Features & Capabilities

  • USB interface: Mostly USB 2.0 High Speed (480 Mbps); some revisions may support higher host-side features but generally not USB 3.x.
  • Flash management: Flash Translation Layer (FTL), wear leveling, bad-block management, read-retry support.
  • Error correction: Built-in ECC (often BCH); capability varies by controller/firmware.
  • Power management: Low-power idle states; features depend on controller firmware.
  • Security: Some vendor firmwares add password protection or secure partitioning; not standardized.
  • Over-provisioning: Some drives allocate extra NAND space for longevity — vendor-dependent.

The "Short Pin" Method (Firmware Repair)

You don't need expensive tools to revive a bricked PS2251-07. You need a paperclip and the Mode 3/ Mode 8 trick.

  1. Download MPALL (MPTool): Get version v3.xx or higher specifically for the PS2307.
  2. Locate the Test Points: Open the drive casing. Look for two tiny copper pads labeled "TP" or two unconnected pins near the edge.
  3. Short the pins: Use tweezers or a paperclip to connect them.
  4. Plug in the drive: While shorted, plug it into a USB port. Windows will make a "connected" sound, but the drive won't appear in Explorer.
  5. Remove the short: The controller is now in ROM Mode (factory state).
  6. Run MPALL: The tool will see the device. Use a "Preformat" or "Erase All" operation to rewrite the firmware.

Warning: This erases your data. Do not do this if you need to recover files. For recovery, use GetDataBack or R-Studio before reflashing.

3.1 Prerequisites: Finding the Correct Tool

The biggest challenge is that Phison MP tools are vendor-specific. You cannot use a generic PS2251-07 tool meant for a Kingston drive on an ADATA drive, because each vendor uses different NAND chips, timings, and firmware.

Steps to identify your exact configuration:

  1. Download ChipGenius (Windows) or lsusb -v (Linux).
  2. Look for these values:
    • VID (Vendor ID)
    • PID (Product ID)
    • Manufacturer string
    • Product string
  3. Search for MP tools using the combination of Controller = PS2251-07 + VID/PID.

Example: Kingston DataTraveler 100 G3 often has VID 0951 PID 1666. The correct MP tool is often labeled MPALL v3.xx or STTOOL v3.xx.
