(commonly known as SP Flash Tool), a utility used to flash firmware onto MediaTek-based Android devices. When you activate this mode—typically by pressing Ctrl+Alt+T
The technical function of this mode is to capture the hand-shake sequence between the PC and the MediaTek SoC. When a device is connected via USB, the Boot ROM (or Preloader) initializes and waits for commands. Runtime Trace Mode monitors this initialization process at a lower level than the standard interface. It captures data such as USB endpoint status, buffer sizes, and the specific return codes from the NAND or eMMC memory controller. For developers and technicians, this data is invaluable. For instance, if a flash operation fails at 10%, the trace log can reveal whether the failure was caused by the USB cable unplugging, a voltage drop, or a bad sector on the device's internal storage.
