This guide details the procedure for performing a Qualcomm Sahara Memory Dump. This is an advanced low-level operation used to extract the entire contents of a device's eMMC/UFS storage (or specific memory regions) when the device is in Qualcomm EDL (Emergency Download) mode.
This process is typically used for forensic data recovery, firmware analysis, or unbricking devices where standard flashing tools (like QFIL) fail to communicate.
# Example using QUTS (successor to QPST) or custom firehose loader:
firehose_client -f programmer.elf -c "read SECTOR_START SECTOR_COUNT output.bin"
firehose_client -f programmer.elf -c "write SECTOR_START input.bin"
The device must be in EDL Mode (Emergency Download). The screen should be black, and Windows Device Manager should show: qpst sahara memory dump upd

When engaging with QPST, Sahara, and memory dump updates, several precautions and steps should be followed: This guide details the procedure for performing a
Backup Data: Before performing any firmware updates or diagnostic procedures, ensure that all critical data on the device is backed up. Some procedures can lead to complete data loss.
Use Authorized Tools: Only use QPST and related tools from authorized sources to avoid any malware or unauthorized modifications. Phase 1: Device Preparation (Entering EDL) The device
Follow Procedures Carefully: Incorrectly following these procedures can result in a device becoming unusable. Always follow the recommended guidelines and tutorials provided by reputable sources.
Ensure Device Compatibility: Make sure that the tools and procedures are compatible with the specific device model and chipset.
