Many users are faced with a situation where a smartphone or tablet starts to work incorrectly, freezes, or consumes battery power faster than usual. Often the cause of such problems is accumulated system errors, conflicts of recently installed applications, or unsuccessful firmware updates. In such cases, the most effective solution is to return the device to its original state, known as a factory reset.
The rollback procedure allows you to clear the internal memory of user data, settings and apps, returning the gadget to the state in which it was immediately after purchase. This is a radical, but often the only way eliminate software failuresthat cannot be fixed by the usual methods of restarting or deleting applications. Before starting any action, it is important to understand that this process is irreversible without a prior backup.
There are several ways to perform a rollback, each of which is suitable for different situations: from the standard settings menu to using the engineering Recovery menu. The specific method you choose depends on whether the device has access to the operating system or is in a bricked state. Below we will analyze in detail all the available options and preparatory steps.
Preparing the device for the reset procedure
Before you begin the process of returning the system to factory settings, you need to perform a number of critical steps. Ignoring this step can lead to the irretrievable loss of personal photos, contacts and documents. Android does not provide a built-in recycle bin for files deleted during a reset, so responsibility for saving them lies entirely with the user.
The first step is to create a backup copy of the data. You can use cloud services such as Google Photos for media files and Google Drive for documents, or sync contacts with your Google account. For a more complete copy, including application and SMS data, it is recommended to use a local backup on a computer or external drive.
You also need to make sure that the device's battery charge is at least 50-60%. The process of formatting memory partitions can take anywhere from 10 minutes to an hour, and a sudden power cut in the middle of the procedure can damage the bootloader. If your phone has a removable battery, it is better to insert a fully charged battery.
- 📸 Back up photos and videos to the cloud or PC.
- 📞 Sync your phone book with your Google account.
- 🔋 Charge your device to at least 60% before starting procedures.
- 🔑 Remember or write down the passwords for your Google account and lock screen.
⚠️ Attention: After resetting, the device will ask for owner confirmation. If you do not remember the password for the main Google account that was synchronized with the phone, it will be extremely difficult or impossible to unlock it due to the FRP protection system.
☑️ Ready for rollback
Standard reset through the settings menu
The easiest and safest way to perform a rollback is available if the operating system is stable and you can get into main menu. This method does not require connecting to a computer or using special button combinations. The interface may differ slightly depending on the version Android and the manufacturer's shell, but the logic of action remains the same.
You need to open the “Settings” application and find the section responsible for the system. In pure Android this is usually the item “System” → “Advanced” → “Reset settings”. On devices Samsung the path may look like “General settings” → “Reset”, and on Xiaomi - “Advanced settings” → “Backup and reset”.
In the menu that opens, select the option “Reset settings” or “Delete all data (reset to factory settings)”. The system will warn you that all data will be deleted. Once confirmed, your phone may ask you to enter your screen unlock PIN or account password for security. As soon as you confirm the action, the device will reboot and begin the cleaning process.
The duration of the procedure depends on the amount of internal memory and the number of files. The screen may fade in and out, and the progress bar will show the percentage of completion. Do not interrupt the process or try to turn off the phone manually.
What to do if the reset menu is inactive?
If the menu item is locked, check to see if Do Not Disturb is enabled or the encryption process has started. Also, access may be limited by device administrator rights in corporate profiles.
Using Recovery mode for hard reset
If the system does not boot, freezes on the logo or the touch screen does not respond, the only option is to use the mode Recovery. This is a special diagnostic interface, recorded in a separate memory section, which allows you to control the device at a low level. Navigation here is carried out using the volume buttons, and the choice is confirmed by the power button.
To enter this mode, you need to turn off the smartphone and hold down a certain key combination. There is no universal combination, but the most commonly used combination is holding the volume up button and the power button. On devices Samsung with a physical Home button, you may need to hold down all three buttons at the same time. It is better to check the exact combination for your model in the manufacturer's specifications.
After the logo or menu with text appears, release the buttons. In the list of options, using the volume rocker, find the item Wipe data/factory reset. Confirm your selection with the Power button. Next, the system may ask for confirmation, prompting you to select Yes or Factory data reset.
After completing clearing the data sections, select Reboot system now. The device will reboot and the initial setup will begin, as when you turn on a new smartphone for the first time. This method is guaranteed to delete all user data and settings, returning the system to a clean state.
- 🔽 Turn off the device completely before starting manipulations.
- 🔘 Press the combination of buttons (usually Volume Up + Power).
- 📉 Use the volume buttons to navigate the menu Recovery.
- ✅ Select Wipe data/factory reset for a complete reset.
If the sensor in Recovery does not work, this is normal. Control in this mode is carried out exclusively by mechanical volume and power buttons.
Rollback via computer using ADB
For advanced users who have access to a PC, there is a reset method via USB debugging. This method requires preliminary installation of drivers and utility ADB (Android Debug Bridge) on the computer, as well as the “USB Debugging” option enabled in the developer menu on the smartphone itself.
Connect the device to the computer via the original cable. Open a command line or terminal in the folder where ADB is installed and enter the command to test the connection: adb devices. If a device with status deviceappears in the list, then the connection is established correctly.
To perform a reset, enter the command adb reboot bootloaderto enter bootloader mode, from where you can select Recovery, or use a direct command to reset if access rights allow: adb shell recovery --wipe_data. However, the most reliable way is to switch to recovery mode with the command adb reboot recovery, and then perform the standard actions through the Recovery menu described above.
This method is especially useful when the touch screen is partially not working, but the system responds to commands from the computer, or when the volume buttons are faulty. It gives full control over the reboot process and allows you to bypass some software blocking of the interface.
adb reboot recovery⚠️ Attention: ADB commands are executed instantly and without additional confirmation on the phone screen. An error in syntax or choosing the wrong command can lead to unexpected results. Be careful when entering.
Comparison of reset methods and their features
The choice of rollback method depends on the current state of the device and the user’s goals. Each method has its own advantages and limitations. Understanding these differences will help you avoid unnecessary steps and wasted time. Below is a table comparing the main characteristics of the considered methods.
| Method | Requires access to the OS | Complexity | Risk of errors |
|---|---|---|---|
| Through Settings | Required | Low | Minimum |
| Recovery Mode | Not required | Average | Average |
| Through ADB | Desirable (debugging) | High | High |
| Service code | Required (screen) | Low | Medium |
Use of service codes such as ##7780##is also possible on some models, but this method is less universal and depends on the manufacturer. This often duplicates the menu reset function, but can be useful if the system interface is badly damaged, but the display and input work.
It is important to note that none of the software methods will help if the bootloader is damaged or there is physical damage to the board. In such cases, flashing through special utilities (Odin, MiFlash, SP Flash Tool) or repair at a service center is required.
The safest and recommended method for the average user is a reset through the standard settings menu, as it minimizes the risk of accidentally selecting the wrong option.
Data recovery and initial setup
After the rollback procedure is successfully completed, the device will reboot and the welcome screen will prompt you to select a language and connect to the Wi-Fi network. This is the beginning of the initial setup phase. The system Android will try to determine whether this Google account has been used on this device previously, as part of FRP protection.
Enter the login and password for your Google account. If you created a backup, the system will offer to restore data from it. You'll be able to choose which apps, contacts, and settings you want to get back. The recovery process may take some time depending on the amount of data and Internet speed.
Do not rush to install all applications at once. Allow the system to complete background indexing and updating processes. This will help avoid false sensations of “brakes” immediately after the reset. Check the operation of the main functions: calls, Internet, camera.
- 🌐 Connect to a stable Wi-Fi network to download a backup copy.
- 🔐 Enter the details of the Google account that was used previously.
- 📲 Select a backup copy to restore data from the list.
- ⏳ Wait until all system updates are installed.
⚠️ Attention: If after resetting the device requires you to enter the password for the Google account that was previously synced, but you do not remember it, restoring access through standard methods may not be possible. Make sure your account data is up to date before resetting.
Frequently asked questions (FAQ)
Will the operating system be deleted when resetting to factory settings?
No, the operating system Android is not deleted. The reset only affects the partition with user data (/data) and the cache (/cache). System files remain intact, so after a reboot you will get the same version of Android, but in a clean state, without your personal files and installed applications.
Is it possible to recover deleted photos after a rollback?
Recovering data after a full reset (Factory Reset) is extremely difficult, and often impossible, since the encryption keys are destroyed. If you did not have a backup copy in the cloud or on your computer, you will not be able to return the files using standard means. Specialized data recovery software is rarely effective on modern devices with encryption.
How long does the reset process take?
Usually the process takes from 5 to 15 minutes. The time depends on the amount of internal memory of the smartphone and the amount of data that needs to be erased. On devices with large storage capacity (128 GB or more), formatting may take longer. Do not interrupt the process, even if the screen remains black for a long time.
Do you need to remove the SIM card and memory card before resetting?
You can leave the SIM card in place, it will not be affected. It's best to remove the microSD card to avoid accidental formatting if you select the "Wipe internal memory and SD card" option. If the card is used as part of the internal memory (adaptive storage), it will be formatted along with the phone.
What to do if the phone freezes after a reset?
If the device hangs on the logo for a long time (more than 15-20 minutes), try performing a forced reboot by holding down the power button for 10-15 seconds. If the problem repeats, the system files may be damaged, and you will need to reflash the device via a computer using the manufacturer's official sources.
