How to Destroy Xiaomi: From Complete Reset to Firmware Reflashing

The decision to “make” the operating system on Xiaomi’s smartphone often comes at times of critical failure, selling a device or wanting to completely clean the gadget of digital garbage. In the context of MIUI and HyperOS users, this term refers to actions ranging from a banal reset to factory settings to complete firmware reflash with unlocking the bootloader. It is important to immediately determine what level of intervention your device needs to avoid losing important data or turning the smartphone into a “brick”.

The memory cleanup and software reinstallation procedure on Xiaomi, Redmi and POCO devices has its own unique security features. Unlike many other manufacturers, there is a strict binding to the Mi Account and a mandatory procedure for waiting for the bootloader to unlock. Ignoring these nuances can lead to the phone being locked during the activation stage, requiring a password from the previous owner’s account.

In this article, we will look at all the steps of the process, from preparing backups to using the specialized Mi Flash Tool software. You will learn how to properly prepare the device, what risks exist when interfering with the system partition and how to avoid typical errors. Complete deletion of data is an irreversible process, so it should be approached with the utmost care and understanding of each step.

Choosing a cleaning strategy: resetting or flashing

Before we start radical action, we need to clearly distinguish between reset and flash. Standard reset via the settings menu deletes user data, but leaves system files and unuched settings. This is suitable for selling the phone or eliminating small software glitches. Firmware reflashing involves writing a new system image to the device's memory, which is often required in case of serious failures or to change the firmware region.

If your goal is simply to clean the phone before selling, then using the built-in recovery feature will be the safest and fastest option. However, if the device hangs on the logo, goes into a cyclical reboot or is infected with malware that is not removed by antivirus, a deeper intervention will be required, in such cases a clean installation is the only right solution.

The status of the bootloader should also be considered. On Xiaomi devices, it is blocked by default, which prohibits the installation of modified systems or custom recavators. Full-featured flashing often requires its unlocking, which is officially only possible after filing an application and waiting from 7 to 30 days. Unlocking the bootloader automatically cancels the software warranty and erases all data from the device.

Critical Preparation Before Deleting Data

The beginning of any manipulation of the system partition should be accompanied by the creation of a full backup. In the Xiaomi ecosystem, there is a built-in application “Mi Mover” or the Mi Cloud service. It is important to save not only contacts and photos, but also key data of the applications, if such a feature is supported. Losing correspondence in messengers or progress in games will be an unpleasant surprise after formatting.

Special attention should be paid to unbundling accounts. Before you demolish the system, you need to log out of your Google account and, critically, from your Mi Account. If you don't do this, FRP (Factory Reset Protection) protection will go off after the reset, and the phone will require you to enter a password from the last account used, without this data, the device will become a useless piece of plastic and metal.

Be sure to check the battery level. The flashing or deep reset process can take anywhere from 15 minutes to an hour. If the device turns off when you write system files, there is a high probability of damage to memory parts. Connect your smartphone to a power source or make sure that the charge is at least 60-70% before you start the operation.

Standard reset via the settings menu (Soft Reset)

The easiest way to “delete” user data is to use the standard functionality of the MIUI shell. This method does not require a connection to the computer and special knowledge. Just go to the Settings menu → About the phone → Reset. Here the system will offer two options: “Reset” (saves files) and “Erase all data” (full reset).

When you choose to erase completely, the system will ask for a pattern lock or screen unlock password to confirm the identity of the owner, and after confirmation, the cleaning process will begin, which can take several minutes, and the device will reboot and appear in front of you as a new, just unpacked smartphone with a welcome screen.

⚠️ Note: If the phone has Find Device enabled, the system will require you to enter a password from your Mi Account even when resetting through the menu.

This method is effective in 90% of the time it prepares a gadget for transfer to another user, ensuring that personal files, app cache and network settings are deleted, but system debris left over from remote applications or deep registry errors are not always eliminated in this way.

Recovery Mode (Hard Reset)

If the operating system is not loading or the touch screen is not responding, you have to use the Recovery Mode. To enter it on the device turned off, you need to press the key combination: usually Volume Up + Power. Hold the buttons until the Mi logo appears, after which the power can be released, continuing to keep the volume.

In the Recovery menu, you can navigate with volume buttons and you can choose with power buttons, and you can select Wipe Data, then you can choose Wipe All Data, and you can confirm the action, and this method forcibly formats the user partition, ignoring the software locks on the interface, and after the process is complete, you can select Reboot to reboot.

There's also Fastboot mode, which is called by squeezing Volume Down + Power, and in this mode, you see a hare fixing an android on the screen, which is a state you need to connect your phone to your computer and run firmware through special utilities. Just being in a Fastboot, you don't erase the data, it's just a gateway for low-level access.

Full Fastboot Fastboot and Mi Flash

For those who decided to “make” Xiaomi on a professional level, the Mi Flash Tool is designed. This tool allows you to record a clean image of the system (Fastboot). ROM) Directly to the device's memory. ADB/Fastboot, the firmware itself and the firmware file with the.tgz extension (not.zip).

The process is as follows: the firmware archive is unpacked into the root of the C disk (the path should not contain Cyrillic alphabets and spaces). The phone is converted to Fastboot mode and connected to the PC. In Mi Flash, the path is selected to the firmware folder, and at the bottom of the window, the firmware mode is selected.

The most important thing here is to choose the action with the bootloader. If you choose clean all and lock, make sure that the firmware region matches the region of the device. For example, you can not block the bootloader with global firmware on a Chinese device, this will lead to a hard lock (Hard Brick), which can only be removed in the service center through the programmer.

💡

Use the original. USB-cable USB 2.0 on the motherboard (back of the system unit) to avoid communication interruptions during firmware.

Common mistakes and ways to solve them

During the process of demolition, users often encounter a Missmatching image and device error, which means that the selected firmware is not intended for this model. For example, trying to flash the Redmi Note 10 Pro (codename: sweet) firmware from Redmi Note 10 (codename: mojito) will result in failure. Always check the code name of the device before downloading the image.

Another common problem is hanging on the Mi logo after flashing, which may indicate that the file persist or incompatible modem part, in which case it helps to re-flash with clean all mode or roll back to an older version of the software if the current one contains bugs.

⚠️ Warning: Interrupting the firmware process (cable shutdown, PC shutdown) may damage the bootloader. EDL-mode, access to which is often paid or requires opening the case.

Also worth mentioning is the problem with Windows Defender antivirus, which can delete script files from the folder with Mi Flash. Before starting, it is recommended to temporarily disable real-time protection or add a folder with the utility in exceptions.
