QPST is a set of tools that are designed to change some important Qualcomm chipset parameters. They are installed in many smartphones and tablets made by Samsung, Huawei, Lenovo, ZTE, Nokia. Also, these chipsets serve as a "heart" for some modems, because Qualcomm is one of the largest players in the CDMA and 3G networks market.
QPST stands for Qualcomm Product Support Tools. Most often, the need to use this program is mentioned in the manuals for "firmware" of various Android-devices. The tools in this package are used for the most operations. For example, the QPST Configuration module allows you to select a COM port to work with the device, RF Calibration and TM Application tools are used to calibrate and test the RF path, respectively. EFS Explorer is a full-fledged file manager that helps to work with the "contents" of the device. Software Download is a handy "flasher" (it's the one you'll have to use for "firmware" most often), and RF NV Item Manager is an NV memory manager. There are modules in it, the purpose of which is difficult to describe in one sentence. For example, Service Programming, which can be used to configure a variety of device settings. Each of the above described tools is quite "independent" and can work separately from the others.
We strongly recommend that you use QPST carefully and perform all operations in accordance with the manual. Remember that some of the tools in the kit are capable of turning your device into a "brick" when handled incorrectly.
