How to reformat Xiaomi phone: the complete guide

Modern Xiaomi smartphones running on the shell of MIUI or the new HyperOS can accumulate software debris over time that slows down the system. Users often wonder how to reformat the phone to return it to factory speed and get rid of system errors. Complete cleaning of internal storage is a radical but often necessary step to solve performance problems or before selling a device.

The formatting process, or Hard Reset, removes all user data, apps, and settings, bringing the gadget back to the “out of the box” state. It’s important to understand the difference between a conventional reset and deep formatting, especially if the goal is to remove malware or prepare for flashing. In this article, we’ll look at all the available methods, from standard menu settings to using engineering mode.

Before we take decisive action, we need to assess the risks and prepare the device. Failure to perform the procedure can lead to the loss of important photos, contacts and passwords. We will look not only at the process itself, but also at critical stages of preparation that should not be ignored under any circumstances.

Preparation of the device for complete reset

Start with backup, because formatting will permanently destroy information. In the Xiaomi ecosystem, it is convenient to use Mi Cloud cloud service or local computer saving to do this. Make sure that the Mi Account is active and synchronization of contacts and notes is successful.

The second critical point is battery power: the cleaning process and subsequent initial setup can take a considerable time. If the phone turns off at the time of writing system files, it can damage the bootloader. Charge the device to a minimum of 60-70% before any manipulations begin.

⚠️ Note: Deleting your Google and Mi Account before reset is a prerequisite for unlocking your device after rebooting.If you forget the password from your linked Google account, protection will work FRP, And the phone will turn into a brick".

It's also worth checking if there are external devices connected, and if you have a microSD card installed in your smartphone, you'd better remove it before you start the procedure, so you don't accidentally format it with your internal memory, and although the system usually warns you about this, physical extraction is the most reliable way to protect the data on the card.

Reset method through the settings menu

The safest and easiest way to reformat a phone is from a working operating system, which is suitable for most users who want to clean the device of garbage or prepare it for transfer to a new owner. The interface may vary slightly depending on the version. MIUI or hyperos.

To start, open the Settings app and find the About Phone section. At the bottom of the screen, there's usually a Reset button. In some firmware versions, this path may look like Settings → Advanced Settings → Reset. The system will offer several cleaning options.

Select the option "Erase all data." This action initiates a full partition formatting. /data. The system will request confirmation of your actions several times and ask you to enter a pattern lock or PIN-The screen unlock code is a protective mechanism against accidental deletion.

• 📱 Click "Erase all data" in the reset menu.
• 🔐 Enter the screen unlock password to confirm.
• ⏳ Wait until the process is complete, the phone will restart automatically.
• ✅ Go through the initial setup as a new device.

Once confirmed, the cleaning process will begin, which can take 5 to 15 minutes depending on the amount of memory filled, the screen may go out and light up, and the Xiaomi logo will appear several times.

💡

If you plan to sell the phone, don’t sign in to your Google account after the reset so the new owner can activate the device with their data without any linking issues.

Using Recovery Mode for Deep Cleaning

If the operating system is not loading or is unstable, you can reformat the phone through Recovery mode. This method is deeper and allows you to clean the device even if there are software errors that block the entry to the menu.

Turn off the smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then the power button can be released, continuing to hold the volume. In a few seconds, the Recovery menu will open.

Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it. Then the system will suggest you select Wipe All Data. Confirm the action by selecting Confirm.

Once the cleanup is completed, the bottom of the screen will be marked "Data wiped successfully." Now select Reboot and then Reboot to System. The phone will reboot and the new system will start to boot for a long first time.

Formatting via Fastboot and computer

For advanced users who are facing serious failures, there is a method of cleaning through the Fastboot mode. This mode is designed for low-level interaction with the device and is often used in flashing, reformatting the phone in this way only with the help of a computer and special software.

To enter Fastboot mode, turn off your phone and press the power and volume buttons at the same time, and the screen will show an image of a rabbit repairing a robot, or the inscription: FASTBOOT. Connect the device to the computer through high-quality USB-cable.

On PC, you need to use the official Mi Flash Tool or ADB/Fastboot commands. In the Mi Flash Tool, when choosing a firmware for installation, it is important to pay attention to the Clean All option. This option ensures that all memory partitions are reformatted before writing the new system.

• 💻 Install Xiaomi drivers USB Driver on the computer.
• 🔌 Connect your phone in Fastboot mode to your PC.
• 🛠 Run the Mi Flash Tool and select the firmware file.
• 🧹 Select the "Clean All" option for a complete reset.

Using the command line command fastboot erase userdata also allows you to manually clean the user partition, but this method requires high accuracy, since a error in the command can affect system partitions, which will make the phone unrecoverable without a service center.

⚠️ Note: Fastboot mode and use of the Mi Flash Tool may void the warranty if you choose to unlock the Unlock Bootloader for full access.

Cleaning cache and partitions without losing data

Sometimes fullness (formatting) is not required and the problem can be solved by clearing the cache.It's a secure procedure that doesn't delete your photos, contacts or apps, but deletes temporary system files that may have been corrupted.This often solves the interface freeze problems.

Log in to the Recovery menu in the way described above. Find the Wipe Data item. Inside this menu, as opposed to a full reset, select the Wipe Cache option.

Once the cache is cleared, it is also useful to validate files if this option is present in your version of Recovery (Validate), which will check the integrity of the system files. If no errors are found, you can restart the device. If errors are found, you may need a complete firmware reflash.

This method is especially useful after a failed firmware update, when the phone is slow or some functions are not working properly, a "soft" resuscitation option worth trying before drastic measures.

💡

Cache Clearing is a secure procedure that does not delete personal files, unlike Wipe All Data.

Possible problems and solutions

Users can experience a variety of errors during the formatting process, one of the most common being a cyclic bootloop, where the phone constantly displays the logo and does not load any further, which can mean damage to the system partition or incompatibility of the installed version of the software.

If you reset your phone after you reset, you need an account that you don't remember, that's FRP protection, and you can only get around it legally by remembering the data from the Google account that was last synchronized with the device, and Recovery resets don't take that protection away.

Another problem is the “broken” memory sectors, which can cause the formatting process to freeze at a certain percentage, in which case it helps to repeatedly repeat the reset procedure or use specialized software to remark memory, but this is already a task for service center specialists.

• 🔄 Bootloop: Try resetting via Recovery again or flashing.
• 🔒 FRP Lock: Restore access to your Google account through your browser.
• 📉 Hanging on the logo: leave your phone on charging 2-3 hour.
• ❌ Formatting error: Check integrity USB-cable.

It is important to understand that reformatting a phone means returning it to the factory state of the software. If the problems are of a hardware nature (for example, a malfunction of the motherboard or memory), a software reset will not help, but only confirm the need for repair.
