EDL (Emergency Download Mode) , also known as Qualcomm HS-USB QDLoader 9008 mode , is a low-level, pre-boot protocol hardwired into the Qualcomm Snapdragon SoC (System on Chip). Unlike Download Mode (Odin mode), which runs after the primary bootloader (SBL) initializes, EDL runs from the PBL (Primary Bootloader) —a small, immutable ROM inside the CPU.
