A small file (e.g., BN07V*.BIN ) that prepares the controller's RAM to receive the main firmware.
The "Phison MP Tool" is a specialized utility designed by Phison to interface directly with the controller chip of the USB drive. Unlike standard formatting, which only touches the file system, the MP Tool performs a low-level format. It re-writes the firmware (ISP code) and rebuilds the physical mapping of the NAND flash memory.
The primary utility used to service, repair, and reflash the USB 3.0 controller is Phison MPALL . When a USB drive built on this hardware fails—displaying symptoms like "Write Protected," "Please Insert Disk," or recognizing only as "2307 PRAM" (firmware panic mode)—generic formatting tools will fail. You must use a specialized Mass Production Tool (MPTool) and compatible binary firmware files to rebuild the drive’s file system and internal controller parameters.

The is a popular USB 3.0 controller found in many Kingston, Toshiba, and Patriot flash drives. Repairing these drives requires "Mass Production" (MP) tools to reflash firmware or reset the controller. Essential Tool & Firmware Links phison ps225107ps2307 mptool link
Before downloading any production files, you need to identify the exact combination of your drive's controller and flash memory (NAND).
: You must match your controller with the correct BN (Burner) and FW (Firmware) files (e.g., BN07*.bin and FW07*.bin ). Find these at USBDev.ru PS2307 Firmware Library. Step-by-Step Repair Guide 1. Identify Your Chip Details
This is where you'll match the tool to your specific hardware. A small file (e
This often means the burner ( BN07 ) file does not match your memory flash type. You may need to try different BN07 versions available on the USBDev.ru PS2307 page.
Open Device Manager → Universal Serial Bus controllers → Right-click your USB drive → Properties → Details → Hardware Ids . You will see something like: USB\VID_0951&PID_1666 (Kingston). Write this VID/PID down.
With MPTool, users can perform various tasks, such as: It re-writes the firmware (ISP code) and rebuilds
This is where most mistakes happen.
