What is QPST?

QPST (Qualcomm Product Support Tool) is a software package used primarily for flashing firmware, configuring, and diagnosing Qualcomm-based mobile devices, particularly smartphones. It allows technicians and developers to interact with the device's internal settings, update software, and troubleshoot issues. It's commonly used in repair shops, by developers working with Qualcomm chipsets, and sometimes in manufacturing environments.
