Qpst Sahara Memory Dump Now

QFIL does not natively provide a “dump RAM” button. However, you can use the QFIL command-line mode or switch to a Python-based tool.

Better method – Use edl.exe from bkerler’s edl toolset:

edl --loader=prog_firehose.elf --memory=ram read 0x80000000 0x1000000 dump.bin

Or, using QPST’s fh_loader.exe (from QPST/bin):

fh_loader --port=\\.\COM5 --sendxml=dump_memory.xml --noprompt

Where dump_memory.xml contains:

<?xml version="1.0"?>
<data>
<read memaddr="0x80000000" memlen="0x1000000" filename="ramdump.bin" />
</data>

QFIL does not directly have a "memory dump" button. Instead, you must send raw Sahara commands via the Tools → Partition Manager or use the Command Prompt with fh_loader (part of QPST).

Using QFIL Partition Manager (Limited to Partitions):

For a Full Physical Memory Dump (Raw): Use the command-line fh_loader tool (found in C:\Program Files (x86)\Qualcomm\QPST\bin). qpst sahara memory dump

Open Command Prompt as Admin and run:

fh_loader --port=\\.\COM10 --sendxml=memory_dump.xml --memoryname=emmc

You must create an XML file (memory_dump.xml) that defines the memory ranges. Example:

<?xml version="1.0"?>
<data>
 <dump start="0x00000000" end="0x746C00000" filename="full_dump.bin" />
</data>

Note: The end address should be your device’s total storage size: eMMC = (blocks * 512 bytes). Use ls /dev/block in a working device to find mmcblk0 size. QFIL does not natively provide a “dump RAM” button

QPST is a proprietary software suite from Qualcomm for communicating with Qualcomm-based chipsets (MSM, Snapdragon). It includes tools like:

In the realm of mobile device repair, embedded systems engineering, and forensic data recovery, few tools are as simultaneously powerful and misunderstood as the Qualcomm Product Support Tools (QPST) package, particularly its “Sahara” protocol component. The phrase “QPST Sahara memory dump” refers to a specific low-level diagnostic procedure used to extract the full contents of a device’s memory (RAM, and sometimes raw NAND/eMMC/UFS storage) when the main processor—a Qualcomm Snapdragon—is in Emergency Download (EDL) mode. While often associated with unbricking operations, this technique serves as a crucial gateway for engineering analysis, forensic acquisition, and advanced debugging. This essay explores the technical underpinnings of the Sahara protocol, the mechanism of performing a memory dump, its legitimate applications, and the associated risks.
