The Sahara protocol is the primary bootloader communication framework used by Qualcomm technologies. When a device cannot boot into the primary operating system or the secondary bootloader (Fastboot), the Primary Bootloader (PBL) baked into the phone's hardware ROM initializes EDL mode (USB ID 05c4:9008 ).
and ensure your device is listed as a "Qualcomm HS-USB QDLoader 9008" or similar diagnostic port. Enable Sahara Settings Navigate to the Sahara Configuration menu within the QPST Server. Auto Start Sahara Dump
Because it resides in the hardware ROM, the Sahara protocol executes before any secondary software—like the bootloader (ABOOT/LK), recovery (TWRP), or the Android OS—initializes. When a device cannot boot normally due to corrupted partitions or damaged software, the PBL forces the device into EDL mode (recognized by a computer as Qualcomm HS-USB QDLoader 9008 ). qpst sahara memory dump
Before starting the dump process, you must gather the following:
If you're dealing with a specifically branded phone (like a , OnePlus , or Pixel ), you might need specialized EDL mode tools or the firehose programmer meant only for that model. What is your device's brand and model?

Once in EDL, the computer and device use the to communicate. The computer sends a "Hello" command to the device, initiating a handshake. The device responds with its capabilities and version information. Then, the PC uses the Sahara protocol to transfer a Firehose Loader to the device's limited internal memory (SRAM). After a successful transfer and signature verification, the device executes this loader. It then transitions from the simple Sahara protocol to the more powerful Firehose Protocol .
