Afactory reset, also known ashard reset ormaster reset, is a software restore of an electronic device to its original system state by erasing alldata,settings, andapplications that were previously stored on the device. This is often done to fix an issue with a device, but it could also be done to restore the device to its original settings.[1]

Since a factory reset entails deleting all information stored in the device, it is essentially the same concept asreformatting[1] ahard drive. Pre-installed applications and data on the card's storage card (such as amicroSD card) will not be erased.[citation needed]

Factory resets can fix many chronicperformance issues (such asfreezing), but it does not remove the device'soperating system.[2] Factory resets can also be used to prepare a device for sale,refurbishment,disposal,recycling, donation, or other transfers of ownership by removing personal data and settings associated with the previous owner.[3]

Examples

[edit]

Factory resets can be achieved in a variety of ways depending on the electronic device. For some devices, this could be done by going into the device'sService Menu. Other devices may require a completere-installation of the software. The following section lists a few common electronic devices and how they can be reset to factory settings.[citation needed]

Computer factory resets will restore the computer to its originaloperating system and delete all of the user data stored on the computer. Microsoft'sWindows 8,Windows 10 andWindows 11, and Apple'smacOS have options for this.[citation needed]

On devices running theAndroid operating system (mobile telephones, tablet computers, television receivers, etc.) there is a factory data reset[4] option in Settings that will appear to erase all of the device's data and reset all of its settings. This method is typically used when the device has a technical problem that cannot be fixed using other methods, or when the owner wants to remove all their personal data before selling, giving away, returning, or disposing of the device. Factory Reset Protection (FRP) is a security feature implemented in Android devices starting fromAndroid 5.1 Lollipop and later. Its purpose is to prevent unauthorized access to a device that has been lost, stolen, or reset to factory settings. If the user does not recall theGoogle account information, alternative methods such as FRP bypass are utilized to unlock the Android device. After performing a study,Avast reported that the data is recoverable usingforensics software that is fairly generic and publicly available.[5] OnSamsung smartphones, a factory reset operation does not affect theKnox Flag, and consequently does not reset the device to its original factory settings and is not a way to return the device to a state compatible with the manufacturer's warranty. Data on theSIM card and the microSDmemory card is not erased.[citation needed]

Many electronic devices have a menu with tools and settings called the service menu, which commonly includes a tool that performs a factory reset. This tool is most common in devices withdisplays, such as television sets and computer monitors. These menus are usually accessed through a sequence of button presses.

Game cartridges, particularly ones designed forNintendohandhelds that maintainsave data, may feature a factory reset option that can instantly delete all of such data from the cartridge, initiated either by selecting a particular setting in anoptions menu[6] or by inputting a particular button combination during startup.[7][8][improper synthesis?]
