SMI MPTool (Silicon Motion Mass Production Tool)

The is a specialized low-level software utility used to program, repair, and configure USB flash drives that use Silicon Motion (SMI) controllers, such as the SM32X and SM34X series. Primary Functions

Step 6: Start Mass Production

The SM34x Series (High Performance)

Bad Block over setting

| Error Code | Meaning | Solution | | :--- | :--- | :--- | | | Too many physical bad blocks | Reduce total capacity in settings (e.g., 64GB → 32GB) | | Compare Flash Fail | Flash ID mismatch | Wrong MPTool version. Find a newer/older DBF file. | | Download ISP Fail (0x01) | Controller not entering firmware mode | Short the LED or TEST pins on the PCB (hardware fix) | | Preformat Fail | NAND interface voltage wrong | Do not use "High Voltage" mode unless required | | Sensor is Bad | Hardware failure (crystal oscillator dead) | Replace the drive.

⚠️ Warning:

Using the MPTool will erase all data on the drive. It formats the NAND flash memory completely. Do not use this if you are trying to recover files; use data recovery software (like PhotoRec) first. SMI MPTool (Silicon Motion Mass Production Tool) The
