3. Windows 10 Preparation & Updates

Windows 10 often blocks the installation of unsigned drivers required by these tools. The following preparation is mandatory:

A. Disable Driver Signature Enforcement

  1. Press Start and hold Shift while clicking Restart.
  2. Navigate to: Troubleshoot > Advanced options > Startup Settings > Restart.
  3. Press F7 to select Disable driver signature enforcement.

B. Driver Installation

  • MediaTek: Install the MTK VCOM Drivers or MTK USB All Drivers.
  • Qualcomm: Install the Qualcomm USB Driver (often included in the QC Tool folder).

Important Warnings

  • Do not use a USB hub – connect directly to a motherboard USB port.
  • Do not interrupt the flash process – this can hard-brick the device.
  • Do not check “Format all + download” unless you have a full backup of NVRAM (or you’ll lose IMEI).
  • Always match the firmware to your exact model (e.g., Aquaris X5 vs X5 Plus) and region.

Common Errors & Fixes

  • Device not detected:
    • Reinstall drivers, try different USB port/cable, check Device Manager for unknown devices.
  • “FAILED (remote: signature)” or verification errors:
    • You have mismatched firmware; obtain correct signed firmware or unlock bootloader if vendor allows (may void warranty).
  • Stuck in bootloop after flash:
    • Boot to recovery and factory reset (this wipes data). Reflash using correct complete images.
  • Permission denied or write errors:
    • Ensure bootloader unlocked (if required) and run commands as Administrator.
  • Tool crashes on Windows 10:
    • Run in compatibility mode (right-click → Properties → Compatibility) or use an alternate machine/VM.

Error 5: Tool doesn't detect any device (no red bar)

Cause: Driver not installed or device is not in preloader mode. Fix:

  • Open Device Manager. Connect the phone (powered off, Vol down). You'll see a blink of “MediaTek USB Port”. If it changes to “Unknown Device”, your driver is wrong.
  • Uninstall the unknown device, scan for hardware changes, and manually reinstall the usb2ser.inf.
