The Sahara protocol is a proprietary Qualcomm bootloader protocol executed by the Primary Bootloader (PBL) or Secondary Bootloader (SBL) when a device is in EDL mode (frequently recognized by Windows Device Manager as Qualcomm HS-USB QDLoader 9008 ).
Thus, is slightly a misnomer. It should be “QPST Sahara + Firehose Memory Dump.” However, the term persists in forums and tool documentation.
It is common to confuse Sahara with Firehose, as both are used sequentially during an EDL unbricking or dumping session.
Better method – Use edl.exe from bkerler’s edl toolset: qpst sahara memory dump
When a crashed device is connected, QPST should automatically detect the port and prompt to save the dump files.
For anyone working with Qualcomm-based Android devices, encountering a "hard-bricked" state—where the phone shows a black screen but is recognized by a PC as Qualcomm HS-USB QDLoader 9008 Go to product viewer dialog for this item.

The Sahara protocol is used primarily by the primary bootloader in modern Qualcomm chipsets. It facilitates several critical tasks: Reverse Engineering Stack Exchange Image Transfer
Most third-party implementations (like the edl Python tool by bkerler) extend this by iterating through entire memory ranges (RAM from 0x80000000 to 0xFFFFFFFF, then NAND partitions read via later Firehose protocol) to produce a full physical memory image.
Open . It should show Qualcomm HS-USB QDLoader 9008 under Ports (COM & LPT). Open QPST Configuration . It is common to confuse Sahara with Firehose,
The QPST server can be configured to poll for a device that has already sent a "Sahara Hello" packet, meaning the phone is waiting to send or receive data. 4. Resolving Sahara Memory Dump (Unbricking)
QPST is a professional tool suite that is officially distributed only to manufacturers and certified partners, such as Samsung and LG. The public uses leaked versions, which can pose risks. QPST’s power comes from its ability to execute emergency download (EDL) protocols like .
A Windows host PC with the official installed. QPST Software Suite (Version 2.7.496 or newer recommended). A high-quality USB data cable.
A Sahara Memory Dump is the process of extracting a complete, raw copy of a device's RAM when the system has crashed using the Sahara protocol. When a Qualcomm device suffers a "kernel panic" or a critical OS crash, it may enter a special diagnostic state. In this state, the device halts all normal operations and awaits a connection from a PC. When you open , the software listens to the device's diagnostic port. Upon detection, it displays a status of "Sahara Memory Dump" , signifying it is ready to download the crash dump.
