The desire to completely clean the device of accumulated digital debris or get rid of intrusive advertising often leads users to think about how to demolish the system Xiaomi. smartphone owners of this brand face aggressive optimization of the shell MIUI or HyperOS, which can slow down the work of the gadget over time. Deep cleaning or complete reinstallation of the software is an extreme measure, but sometimes the only right solution to restore performance.

There are several levels of interference with the MIUI-based Android operating system, from soft resets to factory settings to complete flashing through a computer with all memory partitions removed. It is important to understand the risks: inept actions can turn a phone into a brick, so you need to carefully study the theoretical part and prepare tools before starting any manipulations.

In this guide, we will look at all the available methods, from standard recovery functions to advanced methods through Fastboot.You will learn how to properly prepare the device, what drivers to install on the PC and how to avoid the typical mistakes that beginners make when working with system partitions.

Preparation of the device before removal of the system

Before taking drastic action, a number of preparatory procedures must be performed. Ignoring this stage can result in the loss of important data or the inability to unlock the device after a reset. Xiaomi has a strict security policy that requires an account to be linked to Mi Account.

The first step should always be to create a full backup. Even if you plan to completely demolish the system, your contacts, photos and documents may be lost forever. Use Google's cloud services or the built-in MIUI backup tool to save data to an external medium.

The critical thing is to turn off the theft protection. If you have a Mi or Google account on your phone, be sure to log out before you reset it, otherwise FRP (Factory Reset Protection) will work, and after you reboot, the phone will require you to enter a password from an old account that you may have forgotten.

• 🔋 Charge the device to minimum 60-70%, Because the process of firmware is energy-consuming.
• 💾 Free up space on the internal drive if you use the Recovery Update method.
• 🔌 Prepare the original. USB-cable, as cheap analogues may not provide stable data transfer.
• 📱 Find out the exact model of your smartphone by looking at Settings → The phone.

⚠️ Note: If you don’t know the password from the Mi Account associated with the device, the procedure for a complete reset will block the phone, in which case the restoration of access is possible only through Xiaomi technical support with a check of purchase.

Full Reset Method through Recovery Mode

The most affordable way to demolish user data and return the system to its original state is to use the built-in recovery mode, which does not require a computer or special knowledge, but it only removes the user partition, leaving system files and ads intact.

To enter Recovery mode, you need to turn off your smartphone and press the button combination. On most Xiaomi and Redmi models, this is a combination of a volume button and a power button. Hold them until the Mi logo appears, then release the power button, continuing to keep the volume.

In the Recovery menu, you can control volume buttons (up/down) and power button confirmation. On modern touchscreen devices, Recovery mode allows you to control your finger. You need to select a language (usually English or Chinese) and go to Wipe Data.

Then select the Wipe All Data option and confirm the action, the system will alert you to the irreversibility of the process, once completed, the phone will automatically restart. The first start can take up to 10 minutes, as the system performs the initial partition configuration.

• 🚫 Do not interrupt the reset process even if the screen is out or there is a delay.
• 🔄 If after resetting the phone again offers to enter the password from the account, this is a normal work of protection. FRP.
• 📲 Touch screen in Recovery can work with a delay, press the buttons confidently.

Using Fastboot Mode for Deep Cleaning

Fastboot mode allows you to interact with your phone at a lower level than Recovery, and through this interface, you can not only reflash the device, but also execute a command to completely clean all partitions, including cache, system and user data, which is a deeper level of intervention.

To get into Fastboot, turn off your phone and press down and power buttons at the same time. The screen will show an image of a rabbit repairing an android, labeled FASTBOOT. This mode will require a computer with ADB and Fastboot drivers installed.

Connect your phone to your PC and open the command line or terminal in the platform tool folder. Enter the command fastboot devices to check the connection. If the device serial number is displayed, the connection is established correctly.

Fastboot uses fastboot erase userdata to execute the Wipe All command, followed by fastboot erase cache. Be very careful: running fastboot oem unlock also initiates a complete data reset, but its goal is to unlock the bootloader to install custom firmware.

Complete flashing through the Mi Flash Tool

If your goal is to completely demolish the current system along with all the modifications, bugs, and tails of previous updates, the best solution is to flash through the Mi Flash Tool. This method requires downloading the full version of the firmware (Fastboot ROM) for your particular model.

Firmware is divided into two types: Recovery (updating on top of the old system) and Fastboot (completely replacing the system image). We need the second type, files have the.tgz extension. You should download them only from official resources or verified archives, such as miui.com or xiaomifirmwareupdater.com.

Once you download the archive, unpack it to the root of the C disk so that the path does not contain Cyrillic characters. Launch the Mi Flash Tool on behalf of the administrator. In the program interface, click the "Select" button and specify the folder with the unpacked firmware.

Select Clean All mode at the bottom of the program window. This mode ensures that the old system is completely wiped out. Press Flash and wait for the process to end. The green success bar means that the system is demolished and re-installed.

• 💻 Use the ports. USB 2.0 on the motherboard, avoiding the front panels of the case.
• 🛑 Do not turn off the cable while writing partitions, this will cause the bootloader to break down.
• 🔓 Fastboot flashing often requires an unlocked bootloader.

⚠️ Note: When choosing the "Clean All" mode + Lock make sure you flash the device in a region corresponding to the bootloader status. Global firmware on a Chinese phone with bootloader lock will cause an error and a cyclical reboot.

Removing system debris and advertising without flashing

You don't always have to demolish the whole system. Often the problem is the bloated cache of applications and system services. MIUI is known for its background processes that collect data and display ads. You can use ADB debugging tools to combat this without getting superuser rights.

Turn on Developer Mode by seven clicks on the build number in the About Phone menu. Then activate USB Debugging. Once you connect your phone to your PC, you can send commands to remove or freeze the system packages responsible for advertising (MSA, Analytics, Daemon).

To safely remove, use utilities like Xiaomi ADB/Fastboot Tools or Universal Android Debloater, which provide a graphical interface and tag safe-to-remove components, making it easier to "facilitate" the system without having to format.

However, it is worth remembering that removing critical system components can disrupt the app store, or even the update system. Deleting the com.miui.misys package can cause Mi Account failures. Always backup the list of installed applications before cleaning.

Recovery after a failed system reset

If the demolition process is not correct, the device can go into a cyclic restart (bootloop) or get stuck on the logo, in most cases, this is solved by re-running through the Mi Flash Tool in Clean All mode.

If the phone is not detected by the computer in Fastboot mode, the bootloader partition may be damaged or the drivers installed incorrectly. Try reinstalling the drivers in Device Manager by selecting the device with a yellow exclamation mark and pointing the way to the Qualcomm or MTK drivers.

In the most severe cases, when the phone does not respond to any buttons and does not charge, it may require intervention at the hardware level (EDL mode for Qualcomm processors or BROM for MediaTek).

• 🔍 Check integrity USB-cable and port for oxidation.
• 💻 Try another computer or laptop to rule out problems with OS drivers.
• 🔋 Allow the battery to fully discharge to zero, then set to charge for 30 minutes without turning on.
