SP Flash Tool (SmartPhone Flash Tool) has long been the industry standard for flashing firmware, recovery, and preloader files on devices powered by MediaTek (MTK) processors. Version 4.8.0 represents a mature, stable release that balances legacy device support with the features required for early Android 10 and 11 chipsets.
Whether you are unbricking a dead phone, upgrading to a custom ROM, or restoring stock firmware, SP Flash Tool 4.8.0 remains a go-to utility for technicians and enthusiasts.

You can also use MTK Driver Installer 1.4 or MediaTek DA USB VCOM drivers.
After installation, restart your PC. To verify: Connect your powered-off phone via USB. In Device Manager, you should see "MediaTek PreLoader USB VCOM Port (COMx)" flashing briefly.
