Purpose: The preloader is a low-level boot component for MediaTek (MTK) devices. It initializes critical hardware (power rails, clocks, DRAM) and provides a handoff to the next boot stage (little or main bootloader).
Role in flashing/unbricking: Required for full firmware flashing and often necessary when a device is bricked at a very early stage (no USB enumeration, no adb/fastboot). A correct preloader ensures the phone’s hardware is initialized so tools (e.g., SP Flash Tool) can communicate with the device.

How to identify the correct preloader
Confirm exact device model and hardware variant (check Settings > About phone, packaging, or under battery compartment if removable).
Check board/chipset (MT6765 etc.) via fastboot/adb (if available) or by opening device and inspecting board markings.
Match the preloader to:
Unbricking: If a Redmi 9C (codenamed Angelica) is stuck in a bootloop or won't turn on, a custom preloader is often used with tools like SP Flash Tool to bypass authentication (Mi Auth) and flash a stock ROM.
