How to Demolish Xiaomi Phone: From Settings Reset to Clean Firmware

Situations where the owner of a Xiaomi smartphone needs to completely demolish the system arise for various reasons: it can be a sale of the device, critical operating system errors, viruses or just wanting to start from scratch after a lot of experimentation with settings. It is important to understand that the phrase “demolish the phone” users often mean two different processes: software reset (hard reset) and complete flashing of the device from the computer.

The first option is a regular feature available to each user, which returns the gadget to the state “out of the box”, removing all personal files, accounts and applications. The second option involves a deeper intervention in the memory structure, often with a regional firmware (e.g., Chinese firmware to global firmware) or recovery from major bootloader failures. MIUI or hyperos.

Before you start any manipulation, you need to be aware of the risks. Interrupting the data recording process can cause the smartphone to turn into a brick and stop turning on. So be sure to have a battery charge of at least 60-70% and a USB cable is healthy and provides a stable connection. In this article, we will discuss all the ways to completely clean the device, from simple settings menus to using engineering software.

Preparation of the device before complete reset

Starting with the most important step, data retention: Once you decide to demolish your phone, it will be impossible to return deleted information without specialized (and expensive) recovery. Backup is not just a recommendation, it is a necessity. Check if your contacts are synced with your Google account or Mi Cloud, and copy photos and videos to your computer or external drive.

Two-factor authentication is a special focus, and if you've linked a phone number or authentication apps to important services, make sure you have access to them from another device. SIM-The card may not be immediately activated in the new profile, or you may lose access to the confirmation codes, and be sure to log out of all important accounts manually if you plan to transfer the device to another person.

For ease of preparation, you can use the built-in Mi Mover tool or third-party solutions. However, if the goal is a net sale, it is better to just upload the data to your PC. Make sure you know the passwords from your Mi Account and Google account, as FRP (Factory Reset Protection) security system will require them to enter after a reset to confirm ownership.

Method 1: Standard reset via MIUI settings

The safest and easiest method available when the operating system is stable and you can unlock the screen, is suitable for preparing a smartphone for sale or eliminating software glitches that are not associated with booting the system. The algorithm of actions may vary slightly depending on the version of MIUI or HyperOS, but the logic remains the same.

You need to go to the settings menu and find the section that provides general information about the device. In newer versions of the shell, the path often looks like Settings → About the phone. In older versions of Android, it could be Advanced Settings → Restore and Reset. Look for the Reset button or the Erase All Data button.

⚠️ Warning: Before confirming the action, the system will warn you several times that all files will be destroyed. If you have account protection enabled, the phone may require you to enter the screen unlock password or Mi Account password directly during the reset process.

Once you press the confirmation button, the device will reboot and the cleaning process will begin. The screen can go out and light up, and the progress bar will move in jerks — this is normal behavior. Do not interrupt the process and do not try to turn off the phone with buttons, even if it seems to be getting stuck. Complete cleaning of the data partition can take from 5 to 15 minutes.

💡

If you drop your phone for sale, don't log into your Google or Mi Account after the procedure is completed, but turn off the device immediately. The new owner activates it with their data.

Method 2: Hard Reset with Recovery Mode

If the phone doesn't turn on, it's stuck on the logo, or the touch screen doesn't respond, the only way to detach the data is to use Recovery Mode, which works at the bootloader level and doesn't require an operating system to work, and it's entered by a combination of physical buttons when the device is off.

To enter Recovery on most Xiaomi and Redmi models, you need to press the volume button ("Loudness +") and the power button at the same time. Hold them until the Mi logo appears, then release power, but continue to keep the volume until the Recovery menu appears. Navigation is done with volume buttons (up/down), and selection is made with the power button.

In the Recovery menu, select a language (usually English and Chinese), then go to Wipe Data, you will be asked to choose Wipe All Data, formatting will begin after confirmation, this method also deletes the cache partition, which is useful for frequent system errors, but it does not reinstall the firmware itself, but only cleans the user partition.

• 📱 Wipe Cache – Clearing temporary files, user data is saved.
• 🗑️ Wipe All Data – Full reset to factory state, deletes all photos, apps and accounts.
• 🔄 Reboot – Reboot normally after cleaning is completed.
• 🔙 Back – Return to the previous menu (carefully not to choose an extra one).

Method 3: Complete Fastboot and Mi Flash flash flash flash

For those who want to not just clean up, but completely demolish the current system and install fresh firmware from the computer, Fastboot mode is a professional method that requires drivers, a USB cable and a firmware file in.tgz (not.zip!), an approach often used to change region (CN to Global) or recover from unsuccessful experiments.

First, download the official firmware for your model from miui.com or trusted sources. Unpack the archive at the root of the disk (the path should not contain Cyrillic alphabets or spaces). Then turn the phone into Fastboot mode: turn off the device, press the volume button ("Loudness -") and connect the USB cable to the computer.

Run the Mi Flash Tool on your PC. Press the Refresh button to show the device (the serial number will be displayed). Choose the path to the unpacked firmware folder. The critical point is choosing the firmware mode at the bottom of the window.

Clean all and lock mode should be used with extreme caution. If you try to lock the bootloader by installing global firmware on a device with an unlocked bootloader, or vice versa - Chinese on a global device, the phone will go into a hard bootloop or brick.

💡

Use the Clean All mode for clean installation. Lock mode only if you are 100% sure that the firmware version and the device region are compatible.

Mi and Google account issues (FRP Lock)

Xiaomi smartphones today are heavily protected, and once you reset your settings (especially through Recovery or Fastboot), the security system checks to see if the device has been stolen, and when you first activate it after you reset, you will need to enter a password from a Google account that was synced earlier or from a Mi Account.

It's called FRP (Factory Reset Protection. If you forget your password or you buy your phone with your hands, and the previous owner hasn't untie your device, you'll face a lockdown. It's almost impossible to untie it legally without passwords. So the rule is the same: Before you demolish the phone, be sure to log out of the accounts in the settings: Settings → Mi Account. → Get out and Settings → Accounts and synchronization → Google → Delete the account.

In some cases, if the phone is not connected to the Internet immediately after the reset, the system may miss the check, but this is a temporary measure. Once the device connects to Wi-Fi, the authorization request will appear again. For corporate devices or phones received through the exchange program, it is important to make sure that the device is removed from the list of trusted in the organization profile.

Frequent mistakes and ways to solve them

Unforeseen situations can occur during the reset or flashing process, and one of the most common is the “Can’t verify update” error when trying to install firmware through the file selection menu, which often happens if the version of the software being installed is lower than the current one, or if you are trying to install global firmware on top of Chinese without an unlocked bootloader.

Another problem is the Bootloop, which is an endless reset, and if the phone is stuck on the Mi logo for more than 15 minutes, the system partition may be damaged, and then only a full-cleaning Fastboot flash will help. If this does not help, you may need to re-flash through EDL-a regime that already requires skilled intervention and often paid accounts.

Users also encounter a message saying “This Mi Account doesn’t exist” or network errors, make sure the date and time are set correctly (although they should be automatically pulled up when reset), and check the workflow. SIM-Sometimes a lock is caused by a device being wanted by a person. IMEI in the manufacturer's database, which is relevant for used equipment purchased from hands.

• 🔋 Battery discharge – if the phone is turned off while you’re firmware, charge it and try logging in to Recovery again.
• 💻 Drivers. USB — If your computer doesn’t see your phone in Fastboot, reinstall the drivers. ADB/Fastboot.
• 📉 Lack of memory -- for OTA-Updates need a minimum 2-3 GB of free memory, otherwise the reset may be incorrect.
• 🔒 Locking bootloader – having the “Locked” yellow label in Fastboot means that flashing to another region-version is impossible without unlocking.

⚠️ If after all the manipulations the phone shows a black screen and does not respond to the buttons, it may have gone into mode EDL (In this case, only the charging indicator can be lit on the black screen.

Conclusion and final recommendations

Xiaomi’s complete reset or flash is a powerful tool that can give a device a second life or prepare it for a new owner. However, like any operation with system files, it requires care. The main rule is: seven times measure (backup), once cut (reset).

If your goal is to just speed up, sometimes it's enough to clear the app cache or remove unused software without resorting to drastic measures. But if you decide to tear down the phone completely, follow the instructions Step-by-step, without missing the preparation steps. Using original cables and chargers during the process significantly reduces the risk of failure.

Remember, after the "demolish phone" procedure, the device becomes a blank slate, which is the perfect time not to install a hundred apps at once, but to configure only the minimum necessary to keep the system running for months to come.
