Qualcomm Flash Tool For Mac

Qualcomm MSM based devices contain a special mode of operation, called Emergency Download Mode (EDL). In this mode, the device identifies itself as Qualcomm HS-USB 9008 through USB, and can communicate with a PC host. EDL is implemented by the SoC ROM code (also called PBL). The EDL mode itself implements the Qualcomm Sahara protocol, which accepts an OEM-digitally-signed programmer over USB. The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS).

As open source tool (for Linux) that implements the Qualcomm Sahara and Firehose protocols has been developed by Linaro, and can be used for program (or unbrick) MSM based devices, such as Dragonboard 410c or Dragonboard 820c.
