Modern smartphones, including the popular Xiaomi Mi A1, can run slower over time, accumulate software errors or require cleaning before selling. If your device starts to behave unstable, freeze, or you just want to return it to its original state, formatting will be the optimal solution.
The reset procedure on the Android One lineup, which includes the Mi A1, has its own features that distinguish it from standard MIUI shells. Understanding these nuances will help avoid errors and loss of important information. In this article, we will discuss in detail all the available ways to restore the system, from simple methods through settings to deep formatting through Recovery mode.
Before you take action, you need to realize that formatting is an irreversible process: all photos, contacts, messages and installed applications will be permanently deleted. So backup is a critical step that should not be ignored under any circumstances. Make sure you save all important files to a cloud server or computer.
Preparation of the device for complete reset
In the initial stage of preparation requires careful attention to detail. Insufficient battery charge can lead to interruption of the formatting process, which in the worst case will turn the smartphone into a “brick”. Charge Xiaomi Mi A1 at least to 60-70% to have enough power to perform all system operations.
The second step is syncing data with your Google account. Since the Mi A1 runs on pure Android, your contacts, calendar and app settings are stored in the cloud. Check the sync relevance in Settings → Accounts → Google. It’s also worth manually copying photos and videos to your computer or to Google Photos.
⚠️ Note: If the phone is installed SIM-Remove your microSD card or memory card before starting the procedure, which will protect your personal data on the memory card from accidental deletion and prevent potential file system conflicts during resetting.
Remember to disable FRP (Factory Reset Protection) protection, which requires you to delete your Google account from your device settings or know your password, as after reset, the system will require authorization of the last account you used for security reasons.

☑️ Checklist before reset
Method 1: Reset via the Android settings menu
The most secure and easy formatting method is available directly from a working operating system, which is suitable for most users who have access to the smartphone interface. Go to the main menu and select Settings, then go to the bottom of the list to the System section.
Inside the system menu, find the Additional subsection (in some firmware versions it may simply be called “Additional Settings”). Here you are interested in Resetting. The system will warn you that all data will be deleted and offer several reset options, including cleaning only settings or full formatting.
Select Delete All Data (Reset to Factory Settings) and the screen will show a list of what will be deleted: Google accounts, app data, music and files. PIN-The unlock code or the pattern lock, and once you enter it, you start cleaning it up, which takes a few minutes.
💡
Before pressing the reset button in the settings menu, take screenshots of important Wi-Fi network or Bluetooth device configurations to quickly reconfigure them.
Once the process is complete, the smartphone will automatically restart. The initial launch may take longer than usual, as the system will re-index files and adjust basic parameters. Don't be afraid if the device heats up in the first 10-15 minutes of operation - this is the normal reaction of the processor to intense background load.
Method 2: Formatting with Recovery Mode
If the operating system does not boot, the phone is stuck on the logo or the touch screen does not respond to commands, you will have to use Recovery Mode. This method is deeper and allows you to format Xiaomi Mi A1 even in case of critical software errors.
When the device is turned off, press both the volume button and the power button at the same time. Keep both buttons pressed until the Mi or Android logo appears. Once you see an image of the Android robot (even if it is inverted), release the buttons. If there is a message "No command", press and hold the power button, then once press the volume button.
Volume Up + Nutrition → Hold to the logo → Recovery MenuIn the Recovery menu, you can control the volume buttons (up/down for moving) and the power button (to select). You can find the Wipe data/factory reset. Confirm the choice by selecting Yes or Factory data reset in the next menu.
⚠️ Attention: In Recovery mode, the touch screen is not working, all actions are performed exclusively by mechanical volume and on buttons. Be careful when selecting points, so as not to start unnecessary processes.

Comparison of Resetting Methods
The choice of formatting method depends on the current state of your Xiaomi Mi A1. Each of the described methods has its advantages and applications. Understanding the differences will help you choose the most effective way to solve the problem without unnecessary risks.
The method through settings is less stressful for the user, because the interface is familiar and understandable. However, it requires the system to work. Recovery Mode is a "heavy artillery" that operates at a low level, bypassing the main operating system, but requires greater caution when navigating.
| Characteristics | Through Settings. | Through Recovery. |
|---|---|---|
| Need for access to LOs | Required. | Not required |
| Difficulty of implementation | Low. | Medium |
| Risk of user error | Minimum | Medium. |
| Speed of implementation | Standard. | A little faster. |
If you plan to sell the device, both methods are the same in terms of the result – the data will be deleted. However, for deep diagnosis of hardware problems or after unsuccessful firmware experiments, it is preferable to use Recovery Mode, as it guarantees cleaner partition formatting.
💡
Use the settings menu for a scheduled reset, and Recovery Mode only if the phone is not turning on or is running with critical errors.
Deleting Google Account and Protecting FRP
One of the most important security features in Android is FRP (Factory Reset Protection), which is designed to protect the owner’s data in the event of a phone theft. If you reset without first deleting your Google account, the phone will require you to enter the password from the last synchronized account when you first activate.
For the Xiaomi Mi A1, this means that without knowing the password, it will be extremely difficult to use the device. Before formatting, be sure to go to Settings → Accounts, select your Google account and click Delete Account. This action will break the connection between the device and the cloud profile.
- 🔒 FRP locks the phone after resetting without password.
- 📤 Deleting the account before reset removes the lock.
- 🆘 Without a password, access restoration is extremely difficult.
It’s also worth checking for a Mi Account, although it’s less common on global versions of Android One. If you’ve logged in to any Xiaomi services, you’d better log out early, and this will save you from having to worry about security issues when you first set up after formatting.
Possible problems after formatting
Even after a successful procedure, there are some nuances that can occur: often users experience a battery drain faster than usual on the first day, because the background services re-index files, update applications and sync data, usually after 24-48 hours, the situation stabilizes.
If the phone is stuck on the Xiaomi or Android logo after being reset, the system partition may have been damaged or the update interrupted, in which case it may be necessary to flash the device through the computer using the utility. ADB Or official tools for recovery. Don't panic, let the device go. 10-15 minute.
Another common problem is the lack of communication or Wi-Fi. Make sure that the IMEI or network settings are not damaged during the reset process. If the problem persists after resetting, it may be a hardware malfunction of the antenna module, which requires contacting the service center.
⚠️ Warning: If you've formatted your phone endlessly restarts (bootloop), don't try to do it indefinitely. Discharge the battery completely, then try logging in to Recovery and resetting. If it doesn't work, you need to flash it back.

Initial adjustment after reset
When the formatting process is complete, the Xiaomi Mi A1 will greet you with a welcome screen. Select a language, connect to the Wi-Fi network to activate. The system will check for security updates, which is crucial to do immediately to protect against vulnerabilities.
