When your phone is powered off or bricked, the processor enters a low-level Preloader or BROM mode. The DA file is what initializes the handshake, negotiates baud rates, and tells the phone’s eMMC storage to accept read/write commands.

The Download Agent is a piece of code that is temporarily loaded into the device’s RAM. Once loaded, it takes control of the flash memory operations—allowing you to read, write, or erase the firmware.
