QPST (Qualcomm Product Support Tools) is a suite of software tools designed by Qualcomm for use with their chipsets, particularly for diagnostic and flashing purposes on Android devices. One of the critical components of QPST is Sahara, a protocol or interface used for communication between the device and the computer. It's primarily involved in the process of flashing or updating firmware on Qualcomm-based devices.

Establish the initial "Hello" handshake required before sending firmware images or loaders to a non-responsive device. How to Perform a Memory Dump using QPST

The is a specialized diagnostic process used by Qualcomm-based devices to capture the state of system memory (RAM) immediately following a crash. This process utilizes the Sahara Protocol , a transfer method specifically designed for communication between a PC and a Qualcomm device in its Emergency Download (EDL) or "Dump" mode.
