Resetting your phone to factory settings is a radical but effective way to return the device to its previous performance or prepare it for sale. This procedure deletes all user data, applications and settings, returning the smartphone to its "out of the box" state. However, many users are afraid to perform a reset because of the risk of losing important files or disrupting the system.

In this article we will analyze in detail three main reset methods (through settings, Recovery Mode and using a computer), explain how to do it correctly save data before the procedure, and warn against common mistakes. You will also learn what to do if the phone does not turn on, stuck on the logo or requires a password after a reset. The instructions are relevant for all versions of Android - from Android 8 Oreo to Android 15.

Why do you need a factory reset?

A factory reset is not just a “nuclear option” for fixing errors. This is a tool with clear application scenarios:

  • 📱 Selling or transferring a phone. Deletes all personal information (photos, messages, accounts) without the possibility of recovery.
  • ⚡ Slowdown. If the smartphone slows down due to full memory, application conflicts or data fragmentation.
  • 🔄 Crashes after updating. For example, after installing a new version of Android, the phone stopped turning on or is buggy.
  • 🛡️ Removing viruses. If the antivirus detects malware that cannot be removed using standard methods.
  • 🔧 System errors. Cyclic reboot, black screen, inability to enter settings.

It is important to understand that a reset does not solve hardware problems (for example, a broken screen or a faulty battery). Also, it does not delete files from SD cards —only data from the internal memory.

⚠️ Attention: On some models Samsung, Xiaomi and Huawei after a reset may be required entering your last Google account credentials (FRP lock). If you do not remember the password, the phone will become a “brick.”

Method 1: Reset through the settings menu (the most secure)

This method is suitable if the phone turns on and you can go into the settings. The procedure takes 5–15 minutes depending on the model.

Instructions for pure Android (Pixel, Motorola, Nokia) and most brands:

  1. Open Settings → System → Reset settings (or Advanced → Reset options).
  2. Select Delete all data (reset to factory settings).
  3. The system will prompt you to enter PIN code, pattern or password (if installed).
  4. Press Erase everything or Reset phone (the wording depends on the firmware).
  5. Wait for the process to complete (the phone will reboot 1–2 times).

On smartphones Samsung the path may be different:

Settings → General management → Reset → Reset data

And on Xiaomi (MIUI) look for:

Settings → About phone → Reset settings

Back up important data|Remember passwords for Google and Mi/Samsung accounts|Charge the phone to at least 50%|Remove the SIM card and SD card (optional)

-->

⚠️ Attention: If data encryption is enabled on your phone (usually activated when setting a password), the reset may take up to 1–2 hours. Do not interrupt the process!

Method 2: Reset via Recovery Mode (if the phone does not turn on)

If a smartphone stuck on the logo, does not respond to press or requires a passwordthat you forgot will help Recovery Mode. This method works on 99% of Android devices, but requires precise execution of the instructions.

Steps to enter Recovery:

  1. Turn off phone (press and hold the power button for 10-15 seconds).
  2. Hold button combination (depending on the model):
    • 📱 Samsung: Power + Volume up + Bixby (or Home on older models).
    • 📱 Xiaomi/Redmi/Poco: Power + Volume up.
    • 📱 Google Pixel, Nokia, Motorola: Power + Volume down.
    • 📱 Huawei/Honor: Power + Volume up (on some models you must first hold down Volume up, then Power).
  • Hold the buttons until the brand logo or the Recovery menu appears.
  • In the Recovery menu, use volume buttons for navigation and power button for selection.

    • Further actions:

    1. Select item Wipe data/factory reset (on some firmware - Clear eMMC).
    2. Confirm the action (usually item Yes — Delete all user data).
    3. After completion, select Reboot system now.
    What to do if Recovery Mode does not open?

    If the button combination does not work:

    1. Try another combination (for example, for Samsung sometimes you need to hold Power + Volume up + Volume down).

    2. Connect the phone to charge for 10-15 minutes - sometimes a low battery blocks the input Recovery.

    3. On some models Xiaomi you must first connect the phone to the PC and use the app Mi Flash Tool.

    Brand Combination to enter Recovery Features
    Samsung Power + Volume up + Bixby On new models (S22 and newer), you may need to connect to the PC via Odin Mode.
    Xiaomi/Redmi Power + Volume up On some firmware you need to select a language before resetting.
    Google Pixel Power + Volume down In the Recovery menu, first select Enter fastboot, then Recovery Mode.
    Huawei/Honor Power + Volume up On some models you need to hold the buttons for 10+ seconds.

    Method 3: Reset using a computer (for advanced users)

    If the first two methods did not work (for example, phone does not respond to buttons or Recovery is damaged), you can use official utilities from the manufacturers. This method requires USB cable, computer and special software.

    The most common apps:

    • 🖥️ Samsung Odin —for phones SamsungAllows you to flash the original firmware.
    • 🖥️ Mi Flash Tool — for devices Xiaomi. Requires unlocking the bootloader.
    • 🖥️ Huawei eRecovery — for Huawei i Honor. Works via a button combination + Wi-Fi connection.
    • 🖥️ Android Flash Tool (from Google) - for Pixel and devices with pure Android.

    Example of reset via Samsung Odin:

    1. Download firmware for your model from the site Sammobile or Frija.
    2. Install drivers Samsung USB Drivers.
    3. Run Odin, connect the phone in mode Download Mode (press Power + Volume down + Bixby).
    4. In Odin select the downloaded firmware file (usually with the extension .tar.md5) in the field AP.
    5. Click Start and wait for completion (the phone will reboot automatically).
    ⚠️ Attention: Incorrect firmware via Odin or Mi Flash Tool may disable the phone forever. Use only official firmware for your model!
    💡

    Before flashing firmware via PC, check the phone model in the settings (About the phone → Model) or under the battery. Firmware from a different model will lead to a “brick” (inoperability) of the device.

    What to do after the reset?

    After a successful reset, the phone will turn on in the “as after purchase” state. You have to:

    1. Setting the language and region — select the necessary parameters on the first screen.
    2. Connecting to Wi-Fi —necessary to restore data from a backup.
    3. Login to your Google account —if the phone was linked to account, you will need to enter your login and password.
    4. Recovery data —if you made a backup via Google Drive or Mi Cloud, the system will offer to restore contacts, photos and applications.
    5. Installing updates —after resetting, it is recommended to update Android to the latest version.

    If the phone after resetting requires a password for the old Google account (FRP lock), and you do not remember it, the only official way to unlock it is to enter the correct data. Bypassing FRP through "holes" in the firmware often leads to re-locking or loss of warranty.

    Tips to speed up setup:

    • ⚡ Use quick setup via NFC (if supported) - bring the old phone to the new one to transfer data.
    • 📱 Install only necessary applications —do not download everything to avoid slowdown again.
    • 🔒 Setup biometric unlocking (fingerprint or facial recognition) immediately after logging into your account.

    Typical problems after a reset and their solutions

    Even after a successful reset, problems may occur. Let's look at the most common ones and how to fix them:

    Problem Possible cause Solution
    Phone does not turn on after reset Battery low or failure firmware Connect to charge for 30 minutes. If that doesn’t help, repeat the reset via Recovery.
    Permanent reboot (bootloop) The system partition is damaged Flash the phone via PC with the official firmware (see Method 3).
    Requires a password from the old account Google (FRP) Anti-theft function Enter the correct data or restore access to your account via accounts.google.com.
    No network or SIM card does not work Reset mobile network settings Go in Settings → Mobile network → Operators and select the operator manually.
    Applications are not installed from the Play Market Incorrect date/time settings or Google Play cache Check the date in the settings and clear the cache Play Market i Google Play Services.

    If after resetting the phone does not see the SIM cardtry:

    1. Remove and insert SIM card again.
    2. Update operator settings manually (in the mobile network menu).
    3. Reset network settings: Settings → System → Reset → Reset network settings.
    💡

    If after resetting the phone began to work slower, than before the procedure, most likely the problem is in the hardware (worn out battery, overheating of the processor). In this case, resetting will not help - you need diagnostics at a service center.

    How to avoid data loss before resetting?

    The main fear of users when resetting is loss of photos, contacts and messages. To prevent this from happening, perform a backup in advance.

    Ways to save data:

    • ☁️ Google Account:
      • Automatically saves contacts, calendar, notes.
      • Photos and videos can be downloaded to Google Photos (settings → backup).
      • Applications and their data - in Settings → Google → Backup.
    • 📱 Local copy to PC:
      • Connect your phone via USB, select mode File transfer.
      • Copy folders DCIM (photo), Downloads (downloads), WhatsApp (chats) to your computer.
    • 🔄 Third-party applications:
      • Swift Backup (requires root) - saves applications and their data.
      • Titanium Backup —for experienced users.
      • Samsung Smart Switch / Xiaomi Mi Mover —official utilities for backup.

    What is not saved when backing up via Google:

    • 📁 Files in folders not associated with the account (for example, downloaded documents in Download).
    • 🎮 Game saves (if the game does not support cloud synchronization).
    • 📞 Call log (on some firmware).
    • 🔐 Wi-Fi passwords (saved only if synchronization in Chrome).
    💡

    To save SMS, use the application SMS Backup & Restore. It exports messages to a file that can be restored after the reset.

    FAQ: Frequently asked questions about resetting Android

    Can I cancel the reset after the process has started?

    No. After confirming the reset, the process cannot be interrupted - this will lead to damage to system files. If the phone stuck during reset, wait until the battery is drained (if possible) or contact a service center.

    Does the reset remove viruses?

    Yes, full reset deletes all user data, including malware. However, if a virus has entered system files (for example, through root access), flashing may be required.

    How to reset your phone if you forgot the pattern key?

    Use Recovery Mode (Method 2) or Find My Device from Google (if synchronization is enabled). To do this:

    1. Go to the website google.com/android/find.
    2. Select a locked phone.
    3. Click Erase device.

    ⚠️ After this, all data will be deleted, including the lock password.

    Reset will help if the phone does not turn on?

    If the phone does not respond to charging or does not show signs of life, resetting will not help - the problem is most likely in the hardware (battery, motherboard). If the phone vibrates or logo lights up, try resetting via Recovery.

    Is it possible to reset only the settings without deleting files?

    Yes, some phones have an option Reset settings (without deleting data). However, it clears only:

    • Wi-Fi, Bluetooth settings.
    • Accounts (except the main Google account).
    • Application settings.

    Photos, videos and documents will remain untouched. But such a reset will not help in case of serious lags or viruses.
