How to wipe the system on Redmi: a complete guide

Smartphone users Redmi i Xiaomi sometimes face situations where the standard operation of the operating system becomes impossible. Malware, critical errors after a failed update, or simply the desire to get a “clean” slate to sell the device require drastic measures. Complete removal of the current firmware is a process that cannot be called a simple reset, since it affects system memory partitions.

There are several levels of intervention in the operation of the device: from a soft reset through the settings menu to a complete flashing via a computer using special software. The choice of method depends on whether the phone turns on at all and whether you have access to basic functions MIUI or HyperOS. It is important to understand that any action aimed at erasing data irreversibly deletes all personal information without the possibility of recovery.

Before taking active steps, you need to understand the risks. The wrong sequence of steps can turn a smartphone into a “brick” that cannot be restored at home. However, if you are ready to follow the instructions and understand the responsibility, we will look at all the available ways to clear memory from the old system.

Device preparation and backup

Any intervention in system files requires preliminary preparation. Even if your goal is to completely destroy your current system, you may need drivers, firmware files, or access to accounts for subsequent activation. The first step is always to save important data to an external drive or cloud storage.

Make sure the battery is charged at least 60-70%. The flashing or resetting process can take anywhere from 10 minutes to an hour, and a sudden power cut at a critical time of data writing will damage the bootloader. Also prepare an original USB cable, as poor-quality wires often cause loss of connection when transferring large amounts of data.

⚠️ Attention: After resetting or flashing, Mi Account Lock protection is triggered on Xiaomi devices. If you don't know the password for your Mi account, your phone may be blocked forever. Make sure you remember your login information or unlink the device from your account in advance in the settings.

For users planning deep cleaning via a computer, you will need to install drivers ADB and Fastboot. Without them, the PC will not see the smartphone in a special service mode. Download the archive with drivers from the official developer portal or trusted sources and unpack it to the root of drive C for ease of working with the command line.

Soft reset via the settings menu (Factory Reset)

The safest and most accessible way to “erase” user data and return the system to its original state is the reset function in the menu. This method does not remove the operating system itself, but erases all data partitions, cache and settings, essentially making the phone the same as it was at the time of purchase.

Go to the menu Settings and find the partition About phone. At the bottom of the screen there is usually a button Reset settings. The system will offer two options: “Reset all settings” (saves files) and “Delete all data”. For complete cleaning, choose the second option. The process may take several minutes, after which the device will reboot.

If the interface is unstable, you can use the settings search. Enter the phrase “reset” or “factory reset” in the search bar. This will allow you to quickly find the desired menu item, even if the shortcuts are hidden or moved in new versions of the shell HyperOS. After confirming the action, the phone will begin formatting the internal storage.

Hard reset via Recovery mode

When the system does not boot or is locked with a pattern, the only way to clear the memory is to use the mode Recovery. This is a service menu hardwired into the phone's memory regardless of the main OS. You can enter it using a combination of physical buttons when the device is turned off.

Turn off the smartphone completely. Press and hold the Volume Up button and the Power button at the same time. Hold them down until the logo Redmiappears, then release the Power button, but continue to hold down the volume until the recovery menu appears. Navigation in this menu is carried out with the volume buttons, and selection is done with the power button.

You need to find the item Wipe Data. In some versions of Recovery, it may be hidden in a submenu or require confirmation by entering a code word that appears on the screen (for example yes). Select an option Wipe All Data and confirm the action. After the process is completed, select Reboot to reboot into the system.

Action	Control buttons	Result
Enter menu	Volume + and Power	Start Recovery Mode
Navigation	Volume Up/Down	Move through items
Select item	Button Power	Command activation
Exit	Reboot to System	Reboot to Android

What to do if the Recovery menu is in Chinese?

If you are in the Chinese Recovery menu, do not panic. Usually the items are arranged in the same order. The data clearing item is often second or third from the top. Focus on the hieroglyphs that look like “clear” (usually contain the radical of water or hands), or simply select the second menu item, confirm with the second button below, and then select the top button to reboot.

Full flashing via Fastboot

For those who want not just to clear data, but to completely replace the system partition, there is a mode Fastboot. This method allows you to write a new firmware image directly to the phone's memory, ignoring the installed system. This is the most effective way to “demolish” the old OS.

Put your phone into Fastboot mode by holding down the volume down and power buttons at the same time. An image of a hare in earflaps repairing a robot will appear on the screen. Connect your device to your computer. To work, you will need a utility Mi Flash Tool and downloaded firmware in the format .tgz (Fastboot ROM), which needs to be unpacked into a folder without Cyrillic characters in the name.

⚠️ Attention: When flashing firmware via Fastboot, select mode Clean All in the Mi Flash utility. The option Clean All and Lock will block the bootloader, which is normal for global versions, but may lead to an error if you are flashing Chinese firmware on a global device. Be extremely careful when choosing the firmware region.

Run Mi Flash Tool as administrator. Press the Refreshbutton so that the app sees the connected device (it will be displayed as a serial number). Specify the path to the unpacked firmware and click Flash. The process will take from 200 to 500 seconds. The phone will automatically reboot after completion.

Unlocking the bootloader

Many advanced users tend to demolish the stock system in order to install custom firmware, such as LineageOS or Pixel Experience. However, on devices Xiaomi this is not possible without unlocking the bootloader. By default, it is blocked by the manufacturer to ensure security.

The unlocking procedure requires submitting an application through the official utility Mi Unlock Tool. You need to link your Mi account to the device in the settings (For Developers -> Mi Unlock Status) and wait for the mandatory waiting period, which usually ranges from 7 to 168 hours (from a week to a week). Instant unlocking is practically unheard of now.

After receiving permission in the utility on your PC, switch the phone to Fastboot mode and connect it. Click the button Unlock in the app. All data on the phone will be destroyed during the unlocking process. This is a critical step for those who want to gain full control over the file system and replace Android with an alternative build.

It is worth noting that an unlocked bootloader reduces the security of the device and makes it impossible to use some banking applications and contactless payment services (Google Pay / Mir Pay) without additional manipulations to mask superuser rights.

Possible problems and ways to solve them

In the process of deep intervention in the system, unforeseen situations may arise. The most common problem is “bootloop”, when the phone endlessly reboots at the logo. This often happens when you try to install firmware from another model or when the recording process is interrupted.

If the device is stuck at the logo, try entering Recovery mode again and resetting the data (Wipe Data). If this does not help, you will need to flash it via Fastboot and clear all partitions. In rare cases, when the phone does not respond to buttons and is not detected by the computer, the mode may be required EDL (Emergency Download Mode), to enter which you often need to disassemble the case and close the contacts on the board.

Another problem is an error in account verification after a reset. If the phone requires you to enter a password for your Mi account, and you don’t remember it, it’s almost impossible to unlock the device using the official method. This is an anti-theft measure. In such cases, only contacting the service center with a purchase receipt confirming ownership helps.

⚠️ Attention: The Recovery and Fastboot menu interfaces, as well as the requirements for unlocking the bootloader, may change with software updates. Always check the latest requirements for your specific model on the official Xiaomi community forum before starting the procedures.

Frequently asked questions (FAQ)

Will my warranty be voided after resetting the system?

Regular reset via settings or Recovery does not affect the warranty. However, unlocking the bootloader and installing custom firmware in most regions is grounds for denial of warranty service, since this changes the device software.

Is it possible to restore data after a hard reset?

No. If you selected the "Delete all data" option or formatted via Recovery/Fastboot, the data is overwritten. Specialized recovery apps can help only in rare cases and only if the memory sectors have not been completely rewritten with new firmware.

What is a "Hard Reset" and how does it differ from a regular reset?

Hard Reset is a forced reset to factory settings, performed through hardware buttons (Recovery mode). It is used when the phone does not turn on or is locked. A normal reset is done through the settings menu of a running system. The result for the data is the same - complete deletion.

Do you need the Internet to reset the system on Redmi?

For the reset process itself via Recovery or Fastboot, the Internet is not needed. However, after rebooting during initial setup, the phone will require a connection to Wi-Fi or a mobile network to check your Google and Mi Account, especially if FRP (Factory Reset Protection) protection has been triggered.

How long does a complete flashing take?

The process of writing firmware via Fastboot usually takes from 3 to 10 minutes depending on the size of the image and speed USB port. The first boot after flashing may take longer than usual - up to 10-15 minutes, as the system optimizes applications.
