To understand QFIL, you must first understand . Often referred to as "9008 mode" (for its USB product identifier), EDL is a failsafe built into the boot ROM (read-only memory) of virtually every Qualcomm SoC. Think of it as the device's "last will and testament." When the phone is powered on, the very first code that runs is from this boot ROM. If it cannot find a valid bootloader to launch the system—because the bootloader is corrupted, the partition table is damaged, or the device is otherwise "bricked"—it will fall back to EDL mode.
Unlike standard flashing tools that operate when the phone is powered on or in Fastboot mode, the Flash Loader bypasses the Android operating system entirely. It operates at a hardware level, making it the tool of choice for unbricking, repairing corrupted partition tables, and upgrading or downgrading firmware on completely unresponsive devices.

Do not disconnect the cable during this process.
