Locate the Open UpgradeDownload.exe and open it to launch the SPD Upgrade Tool.
Once it is open, you will get the interface below, and the next step is to click the “SETTINGS” button to locate the .PAC file you extracted recently from the firmware file.
Click Open to load the .PAC firmware file to the SPD Upgrade Download tool.
Power off your smartphone and connect it to the PC using the USB cord.
