Understanding the Phison PS2251-07 (PS2307) Controller The Phison PS2251-07 , often referred to by its hardware ID
, is a widely utilized USB 3.0-to-Flash micro-controller. It serves as the "brain" for many mid-range USB 3.0 flash drives produced by brands like Kingston, Toshiba, and Patriot.
While it is a reliable component for data storage, it gained significant notoriety in the cybersecurity and enthusiast communities due to its susceptibility to firmware modifications and "BadUSB" exploits. Technical Specifications
is designed to bridge the gap between high-speed USB 3.0 interfaces and NAND flash memory.
Interface: USB 3.0 (SuperSpeed), backward compatible with USB 2.0.
Architecture: Supports 1x/2xnm flash memory and various types of NAND, including MLC and TLC.
Performance: Typically offers read speeds up to 100-150 MB/s and write speeds varying based on the paired NAND flash.
Security Features: Includes built-in ECC (Error Correction Code) and wear-leveling algorithms to extend the life of the flash memory. The "BadUSB" Connection
is one of the specific controllers compatible with the BadUSB exploit. Research revealed that the firmware on these controllers could be overwritten to make the USB drive masquerade as a different device type. Keyboard Emulation: A compromised
drive can act as a "Human Interface Device" (HID), typing malicious commands into a computer at lightning speed the moment it is plugged in.
Network Redirection: It can emulate a network card to hijack internet traffic.
Stealth: Because the malicious code lives in the controller's firmware rather than the data storage area, it is invisible to standard antivirus software. Firmware Flashing and Repair Phison Ps2251-07-ps2307-
Beyond security research, users often seek information on the
for repair purposes. If a drive becomes "Write Protected" or shows "No Media" due to firmware corruption, enthusiasts use specialized "MPall" (Mass Production) tools to reflash the controller.
Identification: Users use tools like ChipGenius or Flash Drive Information Extractor to confirm the controller is indeed a Phison PS2251-07 (PS2307).
Firmware Matching: Reflashing requires a specific "Burner" file (BNxx.bin) and a "Firmware" file (FWxx.bin) that matches the specific NAND chip inside the drive.
Restoration: Success with these tools can bring a "dead" drive back to life, though it wipes all existing data. Phison PS2251-07
(PS2307) is a workhorse of the USB 3.0 era. While it effectively handles billions of files daily, its legacy is defined by its flexibility—a trait that makes it both a favorite for hardware repairers and a cautionary tale for digital security.
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 | Topic | PS2251-07 | PS2307 | |---|---:|---:|
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
If you have a USB drive using the Phison PS2251-07 (also known as PS2307)
controller, you are likely dealing with a drive that is "write-protected," unformatted, or completely unrecognized by Windows. This specific chip is a popular USB 3.0 controller found in many Kingston, Toshiba, and Patriot drives, as well as specialized recovery media like the Microsoft Windows 10 Model 1734 sticks. Identifying Your Drive
Before attempting a repair, verify your hardware using a tool like ChipGenius or Flash Drive Information Extractor. Look for: Controller: Phison PS2251-07 (PS2307)
Flash ID: This tells you the specific NAND type (e.g., Toshiba, Hynix), which is critical for choosing the right firmware. Essential Recovery Tools
To fix or repurpose these drives, you generally need specialized "Mass Production" (MP) tools. These are not official consumer software but are often leaked or shared on technical forums like FlashDrive-Repair.
Phison MPALL (v3.70 - v3.89): The standard "Mass Production" tool. It allows you to reflash the controller and partition the drive. Phison ST-Tool: Specifically designed for fixing corrupted
chips that show "Write Protect" or "Device Not Recognized" errors. Firmware Binaries: You will need two types of files: Burner File (BN07.bin):* Prepares the chip.
Firmware File (FW07.bin):* The actual operating code for the controller. Common Troubleshooting Steps
Mode 3 vs. Mode 21: If you are trying to make a bootable drive or an ISO-USB, MPALL allows you to set "Mode 21" to create a CD-ROM partition.
The "Shorting" Trick: If the drive is "dead" (not showing up at all), some users on Tom's Hardware suggest shorting pins 2 and 3 on the controller chip while plugging it in to force it into "Test Mode." Warning: This is risky and requires opening the physical casing.
Read-Only Hardware: Some specific sticks (like the Windows 10 recovery ones) have a physical "write-protect" or OTP (One-Time Programmable) setting in the firmware that may be impossible to bypass without a perfect firmware match.
Note: Reflashing firmware carries a high risk of permanently "bricking" the device. Always backup data first, though if you're looking for these tools, the data is likely already inaccessible.

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.
Tools needed:
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:
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.
If the PS2251-07 is physically damaged (shorted USB connector, cracked PCB, burnt chip), no MP tool will work. However, software recovery is sometimes possible if the controller is still recognized.
