When a powered-off MTK device is connected via USB, the built-in Boot-ROM listens for specific handshake bytes (0xA0). Upon detection, the Boot-ROM loads a minimal Preloader or the DA directly into SRAM.

While newer SP Flash Tool versions are optimized for Android 9-14 and newer chips like the Helio G series or Dimensity, they often drop support for legacy chips. v5.1420 shines with:

Before opening the tool, you must install the correct MTK VCOM Drivers or MTK Preloader Drivers on your PC. Without these, the computer will not recognize the device when you plug it in.
