Refreshing the phone's standard firmware allows you to get rid of problems with the functioning of the software, various freezes and malfunctions of the device. In this case, after resetting the settings (Hard Reset), the firmware of the device will return to its original state, in which it was installed by the manufacturer.
Android
Resetting an Android phone to the factory firmware is performed using the appropriate setting in the phone's menu or by using a key combination (if it is not possible to turn on the phone). To reset the firmware of the switched on phone, go to the "Settings" menu of the device. Then click "About device" and select "Factory data reset". The name of the menu items for invoking the reset operation may vary depending on the version of the operating system of the device and the manufacturer that made changes to the standard firmware. If necessary, enter the security code to reset the software, and then confirm the operation.
If you want to return the phone to the factory state if it is impossible to start it completely, hold down the phone key combination, which can be described in the instructions for using the device, on specialized forums or on the official website of the device manufacturer in the section of technical documentation. Most phones reset their operating system and return their settings to factory defaults when using a combination of the unlock (power) keys, menu and volume down buttons. It is worth noting that some phones use the volume up key to reset the settings. In this case, the power button can be released after starting the smartphone, and the volume and menu keys should be held down for a few more seconds before the formatting process begins.
iPhone
You can also use the corresponding menu item to reset iPhone settings. To do this, go to "Settings" - "General" - "Reset" - "Delete all content and settings". Confirm the operation twice and wait for the phone to return to its factory state.
You can also reset your device using iTunes. Connect your phone to your computer and open iTunes. After that, select the name of the device in the upper right corner of the program. In the "Browse" section, click on the "Restore" button. Remember that resetting the firmware will result in the loss of all saved settings and data, and therefore it is recommended to make a backup before proceeding with the operation.
Windows Phone
Resetting the Windows Phone firmware is also performed using the corresponding function, which is available in the device's settings. Click "Settings" and go to the "Device Information" section, then select "Factory data reset". Confirm the operation twice and wait for the formatting completion notification to appear.
Some Windows Phone models can be returned to factory settings without having to turn on the device. To do this, hold down the volume down button at the same time as the power key. Release the power button. After you see the phone logo, release the volume down key. Then press the volume up, volume down, power, and then volume down buttons in sequence. After that, wait until the settings are reset and the corresponding notification appears on the screen.
