What is EDL Mode?
EDL or Emergency DownLoad Mode is a special boot mode in Qualcomm Android devices that allows OEMs to force-flash firmware files. This special mode of operation is also commonly used by power users to unbrick their devices.
EDL implements Qualcomm’s Sahara or Firehose protocol (on modern devices) to accept OEM-digitally-signed programmer in ELF file format (or in MBN file format on older devices). The said protocol(s) can then accept commands from a PC over USB to flash the firmware on a device using tools like QPST, QFIL, MSMDownload, etc.
When in this mode, the device identifies itself as “Qualcomm HS-USB QDLoader 9008” over a USB connection.
