QCN file is a Qualcomm Calibration Network file. It is a binary file that contains all the calibration information for several elements and sensors of a device, such as Wi-Fi, radio, GPS, IMEI, and touch screen.
The QCN file stores the device’s radio and network configuration parameters, including the IMEI number, baseband version, and other important data. If these configurations are lost or corrupted, such as after a firmware update or as a result of other system-level problems, it can be used to restore them.
