Modern smartphones based on the operating system Android over time may begin to work slower, consume more energy, or produce system errors. Often the only effective solution in such a situation is to completely reset the device to its original state. This procedure, known as Hard Reset or factory reset, deletes all user information and returns the software to the state in which it was when you purchased the gadget.
The need to restore factory settings on Android can arise for various reasons: from the desire to sell the device and clear it of personal data to an attempt to fix critical glitches in the interface. It is important to understand that this process is irreversible without first creating a backup copy. All photos, contacts, correspondence and installed applications will be permanently deleted from the internal memory of the smartphone.
In this article we will analyze in detail all the available methods for performing this operation. You will learn how to safely prepare your device, what types of reset methods exist through the system menu and special recovery modes, and what to do in situations where the phone is locked or won't turn on.
Preparing your device for a full reset
Before you begin the factory reset procedure, it is critical to complete a number of preparatory steps. Ignoring this step can lead to the loss of valuable information, which will later be almost impossible to recover. Make sure that the battery level is at least 50-60%, and ideally connect the smartphone to a power source for the entire duration of the operation.
Backing up your data is the most important step. You can use cloud services, such as Google Drive or proprietary utilities from the manufacturer, for example, Samsung Cloud or Mi Cloud. It is also recommended to manually copy photos and documents to a computer or external memory card microSDif your model supports transferring data to external media.
Before resetting, be sure to remove the SIM card and microSD memory card so as not to accidentally format them along with the internal memory of the phone.
Be sure to write down or remember the data your Google account (login and password). After the reset, the system will require authorization in the previously used account as a theft protection measure (FRP-lock). If you do not remember the password, the device may remain locked forever.
⚠️ Attention: Removing the Google account from the phone settings before resetting (Settings → Accounts → Delete account) will disable FRP protection. If you do not do this, after resetting you will be required to enter the password for this account.
☑️ Preparing to reset your data
Reset through the Android settings menu
The easiest and safest way to reset to factory settings on Android settings, available directly from the smartphone menu. This method is suitable for devices that turn on and allow you to navigate the interface without freezing. The path to the required option may vary slightly depending on the version of the operating system and the manufacturer's shell.
In "pure" Android or on smartphones Pixel, Motorola i Nokia usually you need to go to the section Settings → System → Reset settings. On devices with shells from Samsung, Xiaomi or Huawei this item is often located in the General settings or Advanced settingssection. Look for the wording “Data reset”, “Factory settings” or “Emergency reset”.
After selecting the appropriate item, the system will issue a warning that all data will be deleted. You will need to confirm the action, possibly by entering your current PIN or screen unlock pattern. The process will take from a few minutes to half an hour, after which the phone will reboot into the state of a new device.
- 📱 Go to the main settings menu of your smartphone.
- 🔍 Find the "System","About device" or "Advanced settings" section.
- 🗑️ Select "Reset settings" or "Delete all data."
- 🔒 Confirm the action by entering the screen unlock password.
Using Recovery mode to reset
If the smartphone does not turn on, freezes on the logo or is locked with a forgotten password, the standard menu becomes inaccessible. In such cases, a special recovery mode is used - Recovery Mode. This is a service memory section that allows you to control the system at a low level without loading the main interface.
To enter this mode, you must completely turn off the device. Then you need to hold down a certain key combination. Most often this is the power button together with the volume up button Volume Up. On some models Samsung you may need to connect the USB cable to the computer while pressing the buttons. Hold the keys until the brand logo or the recovery menu appears.
Navigation in the Recovery menu is carried out with the volume buttons (up/down), and the selection of the item is confirmed with the power button. You need to find the item Wipe data/factory reset. After selection, the system may request confirmation of where to select Yes or Factory data reset. When the process is complete, select the option Reboot system now.
What to do if Recovery does not open?
If the standard button combination does not work, try holding down the volume down button instead of up. Some older models require you to press three buttons at the same time: Power, Home and Volume Up. Also try connecting the phone to the charger before turning it on.
⚠️ Attention: In Recovery mode, the touch screen does not work. Be careful when navigating with the buttons so as not to accidentally select the option to format all partitions, if there is one in the extended menu.
Resetting settings via service codes
There is an alternative method that allows you to initiate a reset through a special engineering menu using USSD codes. This method does not work on all devices, as manufacturers often block these functions in new firmware versions for security reasons. However, on older models or some versions Android it may be useful.
To do this, open the "Phone" application and dial one of the following codes: *2767*3855# or ##7780##. The first code usually performs an immediate hard reset without further confirmation, so should be used with extreme caution. The second code often calls the standard reset confirmation menu.
It is worth noting that modern versions Android (starting from 9.0 and higher) often ignore these commands or redirect the user to the standard settings menu. Don't count on this method as your primary method if your device is relatively new. It is more suitable for emergency situations with an old fleet of equipment.
| Code | Action | Risk | Compatibility |
|---|---|---|---|
*2767*3855# |
Instant full reset | High (no confirmation) | Old Samsung, LG |
##7780## |
Reset settings and applications | Medium (confirmation required) | Most Android |
##9876## |
Checking reset status | Low | Rare models |
Reset features on popular brands
Various smartphone manufacturers make their own changes to the menu structure and ways to access recovery functions. Understanding these nuances will help avoid confusion and save time. For example, on devices Xiaomi with a shell MIUI before resetting, you often need to activate the Internet and log into your Mi account to disable the protection.
Smartphones Huawei i Honor may require input Huawei ID password before performing the reset operation through the menu. If you forget this password, the procedure may be blocked. Owners Samsung should remember that on new models, to enter Recovery, you often need to connect the phone to the PC with a cable, otherwise the menu will not appear.
On phones Sony i Motorola the process is as close as possible to stock Android, but the button combinations for entering recovery mode may differ. It is always worth checking the official documentation of a specific model if standard methods do not work.
Each manufacturer has its own data protection logic: Xiaomi requires a Mi account, Samsung requires a connection to a PC for Recovery, Huawei requires Huawei ID. Take this into account when preparing.
- 🔹 Xiaomi/Redmi: It is necessary to disable "Find device" in the Mi Cloud settings.
- 🔹 Samsung: To enter Recovery on Android 11+, you need a USB connection to the PC.
- 🔹 Huawei: It is necessary to synchronize and exit Huawei ID before resetting.
Solving problems after the reset Settings
Once the device is reset to factory settings, you will be faced with the initial setup screen. It is important to act consistently here. Connect to a Wi-Fi network and sign in to your Google account. If the system writes “Invalid account or password,” make sure that you enter the details of the account that was last on this device before the reset.
In some cases, there may be a problem with activation due to server errors or unstable Internet. Try rebooting your router or using a mobile hotspot. If the phone requires a software update immediately after turning on, it is better to agree, since this may fix the bugs that caused the need for a reset.
If the device reboots cyclically (bootloop) even after a reset, this may indicate a hardware failure or damage to the system partition. In such a situation, a soft reset will no longer help, and you will need to flash the device through a computer using special utilities like Odin for Samsung or SP Flash Tool for MediaTek.
⚠️ Attention: Menu interfaces and item names may change with security updates and new versions of Android. If you do not find the exact name of the item, look for synonyms in the “System” or “About device” section.
Why does the phone ask for the old password after a reset?
This is the work of FRP (Factory Reset Protection) protection. Google blocks the device if the reset was performed not through the settings menu (where the password was entered), but through the buttons. This is protection against theft. You can unlock only by entering the old account data.
Frequently asked questions (FAQ)
Will information be deleted from the memory card when resetting?
By default, resetting to factory settings affects only the internal memory of the device. The data on the microSD card should be preserved. However, in the reset menu there is sometimes a checkbox “Empty SD card” - make sure that it is not active if you want to save files on the flash drive.
Is it possible to reset the phone if it is locked and I don’t remember the PIN code?
Yes, this is only possible through Recovery mode (with the volume and power buttons). Resetting through the settings menu is not possible without unlocking the screen. Remember that after such a reset, Google protection (FRP) will work and you will need a password from your account.
How long does the process of restoring factory settings take?
Usually the process takes from 5 to 15 minutes depending on the amount of data and the speed of the smartphone's memory. The first startup after a reset may last longer (up to 10 minutes), as the system optimizes applications.
What to do if after a reset the phone does not see the SIM card?
Try to restart the device again. If this does not help, check whether the SIM card is installed correctly in the tray. In rare cases, it may be necessary to update basic modems through a service center or reflash them.
