Replace the Cable: Use the original USB cable or a high-quality data cable to ensure a stable connection.

Update VCOM Drivers: Open Device Manager, connect the phone, and check if it’s detected as "Mediatek USB VCOM". If it shows as "Unknown," manually update the driver using the Mediatek VCOM Driver Installer. 3. Adjust SP Flash Tool Settings

Run as Administrator: Right-click flash_tool.exe and select Run as Administrator.

Compatibility Mode: Set the tool to run in Windows XP Service Pack 3 compatibility mode via the file properties.

Change Download Agent: In the "Download Agent" field, try selecting MTK_AllInOne_DA.bin from the SP Flash Tool folder. If your device has secure boot, you may need a custom DA file specifically for your phone model.

Uncheck Preloader: Some users find success by unchecking the Preloader partition in the list before clicking "Download". 4. Bypass MTK Authentication (For Newer Devices)
