2. Step-by-Step Guide

Step 5: Configuration (Settings)

Click on the "Settings" or "Parameter" tab. This is the heart of the repair.

  1. Flash ID: Look for the button "Get Flash Info". The tool will query the drive.
  2. Capacity: If the tool detects the NAND correctly, it will auto-select the capacity (e.g., 16GB, 32GB). If it shows "0GB", the NAND flash might be physically disconnected or dead.
  3. Partition Settings:
    • Under "Partition 1", ensure "Type" is set to "Public" or "Removable".
    • Ensure the filesystem is set to ExFAT or FAT32 (ExFAT is recommended for drives over 32GB).
  4. Bad Block Management:
    • If the drive was showing 0 bytes or formatting errors, set "Bad Block" handling to "Replace" or "Skip". The default setting is usually sufficient.

Step 3: Launch the Tool

  1. Plug your defective USB drive into the computer.
  2. Extract the downloaded MPTool (usually an RAR or ZIP file).
  3. Locate the executable file (usually named SMI_MP_Tool.exe or SMI_MP.exe) and run it as Administrator.

Step 6: The "Start" Button

  1. Go back to the main screen.
  2. Click "Start" (or "Burn").
  3. The status bar will show progress (Detecting -> Erasing -> Programming -> Verifying).
  4. If successful, the status will turn Green and say "Pass" or "OK".
  5. If it turns Red and says "Fail", check the error log. Common errors are "Bad Block" or "Timeout".

4. Understanding "Exclusive" Functions

In the context of SM3265AC, "Exclusive" usually refers to the ability to bypass standard safety checks to force a repair: Flash ID : Look for the button "Get Flash Info"

  1. Force Format: If the drive is detected but you cannot format it, the MPTool performs a low-level format (LLF) that ignores the file system corruption and writes fresh factory data.
  2. CD-ROM Partition: The SM3265 supports creating a "CD-ROM" partition (ISO mode). This makes the computer see the drive as a read-only CD. If your drive is stuck in this mode (often used for malware or promotional software), use the MPTool to set the partition type back to "Public" (Removable) to restore it to a normal flash drive.
