A factory reset, also known as a hard reset, is the process of restoring an electronic device to its default factory settings. This can be done for a variety of reasons, such as troubleshooting problems, selling the device, or giving it to someone else. Factory resetting a PS4 will erase all data from the console, including games, saves, and user settings.
There are two main ways to factory reset a PS4. The first is through the console’s settings menu. To do this, go to Settings > Initialization > Initialize PS4 > Full.
