Sprd U2s Diag Driver For Windows 10 64 Bit -

  • Open Device Manager (Win+X → Device Manager). Look for an unknown device or device under “Other devices” or “Ports (COM & LPT)” named like “Unisoc USB VCOM” or “Spreadtrum USB”.
  • Right-click device → Update driver → Browse my computer for drivers → Let me pick from a list → Have Disk → Browse to the extracted folder → select the .inf file → Next → Install.
  • If Windows warns about unsigned driver, accept/Install anyway (if you intentionally disabled signature enforcement).

    • Driver Signature Enforcement is the biggest hurdle. The official driver package (often version 2.0.0.0 or newer) is not digitally signed for modern Windows 10.

    Once installed, the driver appears in Device Manager under Ports (COM & LPT) as SPRD U2S Diag or Unisoc USB Device.

    Stability: Acceptable for short diagnostic sessions, but occasional blue screens (BSOD) have been reported with build 19044+ when rapidly connecting/disconnecting devices.

    Use this if no installer is provided.

    Before installing, verify your system:

    ⚠️ Important: SPRD U2S Diag drivers are not backwards compatible with Windows 7 64-bit in all cases. Windows 10 64-bit has stricter security models. Always ensure you have a driver package explicitly labeled for Windows 10.

    Cause: COM port number > 16 (some legacy SPD tools only scan COM1-16).
    Solution: Change COM port number: Device Manager → Ports → Right-click SPRD U2S → Properties → Port Settings → Advanced → COM Port Number (choose COM1-COM16).

    Note: Always back up NVRAM before making changes via Diag mode – corrupted NVRAM bricks the device's radio.
