Phison Ps2251-07-ps2307- __top__ May 2026

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. Phison Ps2251-07-ps2307-

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). The Phison PS2251-07 (also known as PS2307) is

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

The most "useful" story regarding the Phison PS2251-07 (often paired with firmware PS2307) is the story of "The Trojan Horse in Your Pocket."

This is a story about how a specific hardware component, originally designed for honest data storage, became the central tool in one of the most sophisticated cyber-espionage campaigns in history. Understanding this story is critical for anyone in data security, forensics, or IT procurement. Flash Firmware: Load the specific operating firmware onto

5. MPTool (Mass Production Tool)

One of the most notable aspects of Phison controllers in the enthusiast community is the availability of MPTools.

The MPTool for the PS2251-07 is proprietary software used by manufacturers to:

1. Flash Firmware: Load the specific operating firmware onto the controller.
2. Partitioning: Create CD-ROM partitions (for auto-run software), public partitions, and hidden secure partitions.
3. Low-Level Formatting: Repair drives that have become "write-protected" or corrupted by resetting the flash memory mapping tables.
4. Parameter Tuning: Adjust ECC levels, cache settings, and LED blinking patterns.

Note: In the "grey market" and data recovery communities, finding the specific MPTool version (e.g., MPALL v3.xx) allows users to "reprogram" USB sticks, often to fix fake flash drives (drives reporting false capacities).

Performance Expectations

• Sequential read/write: Varies widely by NAND type and firmware; typical USB 2.0 drives with these controllers often show:
  • Reads: 20–100+ MB/s (peak depends on NAND and host)
  • Writes: 5–40 MB/s (sustained writes lower on TLC)
• Random I/O: Limited compared to SSD controllers; high write amplification possible on cheap NAND/firmware.

Identifying Fake / Low-quality Drives

• Price much lower than market norms, unrealistic capacities listed (e.g., 1 TB for ~$5).
• Inconsistent VID/PID, mismatching controller and NAND reports (use ChipGenius).
• Performance tests (H2testw, F3) reveal real capacity much smaller than advertised.
• Short lifespan or sudden failure after moderate use.
• When suspected, immediately back up and test with F3/H2testw.

Step 3 – Configure MPALL

1. Extract MPALL package.
2. Edit MPALL.ini (or use FC.ini for fixed disk mode):

   [OPTION]
   EraseAllFirst=1
   TestBeforeWrite=0
   Partition=1
   [PARTITION]
   DiskType=1   ; 0=removable, 1=fixed (HDD)
   Format=1
   FormatType=FAT32
   

3. Load correct BN (Burner) & FW files from the FW_PS2251-07/ folder.
