How To Install Mtk Driver Mediatek Preloader Usb Vcom [2027]

Install MediaTek (MTK) Preloader USB VCOM Driver — Windows (concise guide)

Warning: installing unsigned drivers can reduce system security. Proceed only if you trust the source.

Requirements:

• Windows PC (Windows 7/8/10/11)
• USB cable and the MediaTek device
• Driver package containing “Preloader USB VCOM” (from device manufacturer or a reputable source)
• Administrator rights

Step-by-step

1. Download driver package

• Get the Preloader USB VCOM driver package from your device manufacturer or a reputable forum. Unzip to a folder.

2. Disable driver signature enforcement (if needed)

• Windows 10/11: Settings → Update & Security → Recovery → Restart now (under Advanced startup). Choose Troubleshoot → Advanced options → Startup Settings → Restart → press 7 (Disable driver signature enforcement). Windows will boot with enforcement off for one session.
• Windows 7: usually not required; if problems occur, use Test Mode (advanced users).

3. Connect device in preloader/boot mode

• Power off the device completely.
• Some devices need specific key combos (e.g., hold Volume Down or Up) while connecting USB; for many MTK phones, simply insert USB while powered off triggers Preloader mode. Device Manager will later show “MTK USB PreLoader” or “MediaTek PreLoader USB VCOM”.

4. Install driver via Device Manager

• Open Device Manager (Win+X → Device Manager or Control Panel → Device Manager).
• If you see an unknown device or “MT65xx Preloader” with a yellow icon, right-click → Update driver.
• Choose “Browse my computer for drivers” → “Let me pick from a list…” → “Have Disk” → Browse to the driver folder and select the INF file (e.g., preloader.inf or android_winusb.inf).
• If prompted about unsigned driver, accept and continue.
• After installation, the device should appear as “MediaTek PreLoader USB VCOM Port (COMx)” under Ports (COM & LPT) or as an installed USB device.

5. Verify and test

• With the driver installed, use your flashing tool (e.g., SP Flash Tool) — it should detect the device in preloader mode.
• If flashing tool doesn’t detect the device, try:
  • Reinstall driver (remove device in Device Manager and scan for hardware changes).
  • Use a different USB cable/port (prefer rear ports on desktops).
  • Reboot PC after installing driver.
  • Re-run driver signature enforcement disable if required.

6. Re-enable driver signature enforcement (recommended)

• If you disabled it, reboot normally to restore driver signature enforcement (it will re-enable next boot automatically unless you used persistent Test Mode).

Troubleshooting quick tips

• If “Windows failed to install driver”: run Device Manager → uninstall device (check “Delete driver software for this device”), then reinstall using INF.
• Use Zadig only for libusb-style replacements — not typically required for SP Flash Tool.
• Use 32-bit drivers for 32-bit Windows and 64-bit drivers for 64-bit Windows.
• If device never appears, ensure battery isn’t removable and fully disconnected; some MTK tools require the battery connected.

If you want, I can provide:

• Specific driver download links for a particular phone model (tell me the model and Windows version).
• Step-by-step screenshots or an INF-based installer script.

To install the MediaTek (MTK) Preloader USB VCOM driver, you must manually add it as "legacy hardware" because Windows often fails to recognize it automatically. This driver is essential for flashing firmware with tools like the SP Flash Tool.  1. Preparation: Disable Driver Signature Enforcement
