There are several ways to perform a factory reset on the Steam Deck, a handheld gaming device designed by Valve. A factory reset is often used to fix performance issues, corrupted files, or bugs, or to prepare the device for sale. This process wipes all data from the internal storage, including locally installed games and user settings. Before resetting, it's important to back up data not stored in the Steam Cloud, such as save files and controller configurations. To reset the Steam Deck using the Settings menu, open the main menu by pressing the Steam button, then go to Settings and select System. Scroll down to the Advanced section and choose "Reset to Factory State." If you're troubleshooting, toggle on "Reinstall SteamOS." Confirm the action, and the device will begin the reset process, which typically takes 10–15 minutes. If a microSD card is inserted, it won't be affected, but removing it before the reset is recommended. An internet connection is needed to reinstall SteamOS afterward. If the Steam Deck doesn’t power on normally, a factory reset can be done through recovery mode. First, ensure the device is completely powered off by holding the power button for 10 seconds. Then, hold both the Power button and the "..." button. Continue holding the "..." button after hearing the boot sound to enter the SteamOS menu. From there, select "ERASE USER DATA FROM DECK" using the A button, which will remove all user settings, local games, and save data. From the same SteamOS menu, users can also roll back to a previous version of SteamOS by selecting "Previous SteamOS-(build number)." This allows the device to restart using an older version of the operating system while keeping user data intact. However, this change only lasts until the next restart. If the device is being prepared for a new owner, it's advisable to disable "Reinstall SteamOS" to speed up the process and ensure only personal data is erased.
