. Because these drivers are often unsigned, standard installation on modern Windows systems (10 and 11) requires specific manual steps.

Phase 1: Preparation and Disabling Driver Signature Enforcement

Windows 10 and 11 prevent the installation of unsigned drivers by default to protect system security. Since many MTK VCOM drivers lack a digital signature, you must temporarily disable this feature.

Step 2: Install Using Auto Installer (Easiest Method)

1. Extract the driver package.
2. Right-click MTK_Driver_Auto_Installer.exe → Run as Administrator.
3. Click Install.
4. Wait for “Driver installed successfully”.
5. Reboot your PC.

Step 4: Verify Installation

• Open Device Manager → Ports (COM & LPT).
• Reconnect phone in PreLoader mode.
• You should see: MediaTek PreLoader USB VCOM (COM3) (COM number varies).

Problem 1: "The hash for the file is not present" / Driver Signature Error

• Solution: You missed disabling driver signature enforcement. Reboot and repeat the process. On Windows 11, you may need to also disable Memory Integrity (Core Isolation) in Windows Security → Device Security.

Troubleshooting

• Driver conflicts: Sometimes, older or incorrect drivers might cause issues. Try uninstalling previous drivers for your device before installing the MTK driver.
• Windows updates: Ensure your Windows is up to date, as newer updates might fix connectivity issues.

Testing the Driver

Use SP Flash Tool:

1. Open SP Flash Tool → Options → USB COM → select your COM port.
2. Click Download → Connect powered-off phone.
3. If the driver works, the download starts automatically.

Important: The Preloader driver does not permanently stay visible. It only appears during the brief connection window. Once installed, it will automatically load when you connect the phone in powered-off mode.
