Introduction
The “preloader” is a low-level firmware component used on many MediaTek-based Android devices, including the Redmi 9C. It runs early in the device boot process and provides essential hardware initialization and a communication channel (usually via MediaTek’s DA/boot protocol) between the phone and a host PC flashing tool. The preloader file for a particular model contains device-specific initialization code and configuration (clock settings, memory map, PMIC init, USB/serial IDs), so it’s tightly coupled to the exact board/revision and NAND/eMMC configuration.
