Use Phison Restore Utility first. If it fails, use MPTool.
If you have opened up a Silicon Power V3700 USB 3.0 flash drive—or plugged it into a diagnostic tool like ChipGenius—you likely encountered the controller marked (often listed as PS2251-16 or Phison 162).
Once the "Format Successful" or "Device Repair Complete" message appears, click . Step 4: Power Cycle the Hardware Safely eject the USB drive using the Windows system tray. Unplug the drive from the computer. Wait 10 seconds. formatter silicon power v3700 ps2251162
