Owning a modern Xiaomi smartphone often involves a deep setup, especially when standard features no longer meet the user’s needs or the device begins to work unstable. The question of how to drop firmware on Xiaomi becomes relevant when switching from the global version of MIUI to the Chinese, when trying to obtain superuser rights or if you need to eliminate serious software failures.
There are several ways to do this, each with its own technical and preparation requirements. Some methods allow you to save personal data, others involve completely cleaning the memory of the device. Understanding the difference between boot modes and firmware file types is a key success factor. In this article, we will discuss all the steps in detail so that you can safely modify your smartphone software.
Preparation of the device and choice of software version
Before you start any manipulation of system files, you need to do a thorough preparation, as the success of the entire operation depends on it. The first step is to determine the current version of Bootloader, the status of which can be checked in the settings menu or through special utilities. If the bootloader is locked, you will need to officially unlock through the Mi Unlock service, which can take from 7 to 30 days of waiting.
It is also important to choose the right firmware type that will be compatible with your device model: files are divided into Recovery (to update via the recovery menu) and Fastboot (to completely flash through your computer), and an error in choosing a region or model can lead to the phone turning into a brick.
- 📱 Make sure that the battery is at least 60% before the procedure.
- 💾 Make a full backup of all important data to an external medium or to the cloud.
- 🔌 Use the original. USB-cable USB 2.0 on a computer.
- 📶 Check the stability of the Internet connection for downloading drivers and utilities.
⚠️ Note: The use of firmware from another device model is strictly prohibited and will lead to irreversible damage to the hardware.
Required tools and drivers
To succeed, you will need not only the system image file itself, but also specialized software installed on your personal computer. The main tool for working with Fastboot mode is the Mi Flash Tool, which allows you to download images to your phone’s memory. Recovery mode will be enough built-in bootloader and file with the.zip extension.
The critical point is to install the correct ADB and Fastboot drivers. Without them, the computer will not be able to recognize the connected device in a special mode. Often, the Windows operating system automatically installs standard drivers that may not work correctly, so it is better to use the official Xiaomi USB Driver package.
☑️ Firmware readiness check
It is also worth taking care of the availability of an archiver that can work with.tar and.zip formats, since firmware files are often delivered in a compressed form. Before running the firmware utility, it is recommended to close all unnecessary programs to free up system resources and avoid process conflicts.
Recovery Menu Update Method
The easiest and safest way to download firmware on Xiaomi is to use the built-in recovery menu.This method does not require a connection to a computer and is suitable for installing updates in Recovery ROM format. First, you need to put the downloaded firmware file in the root of the internal memory of the device, renaming it to update.zip to avoid recognition errors.
Once you have the file, you need to go to Recovery mode. To do this, turn off your smartphone and press the volume button and the power button at the same time. When the Mi logo appears, release the power button, but keep the volume until the menu appears. In this interface, volume buttons control the control, and the choice is confirmed by the power button.
From the menu, select Wipe Data if you want to clean it completely, or go straight to installation. However, cross-regional updates (e.g. China to Global) often require a pre-reset. Once you select Install update.zip, the verification and installation process will begin.
| Parameter | Recovery ROM | Fastboot ROM |
|---|---|---|
| File extension | .zip | .tgz |
| The need for a PC | No. | Yes. |
| Data retention | Maybe. | Only with cleaning. |
| Speed of installation | Hurry up. |
⚠️ Note: When moving between different regions (CN ↔ Global) through Recovery be sure to do a full data reset (Wipe All Data), otherwise there will be a cyclical reboot.

Fastboot and Mi Flash Tool
A more advanced method that gives full control over memory partitions requires the use of Fastboot mode. To enter this mode, you need to turn off the phone and press the power and volume buttons simultaneously, and an image of a rabbit repairing an android will appear on the screen, which signals the device is ready to receive commands.
Run the Mi Flash Tool on your computer and connect your smartphone with a cable. The utility should identify the device by displaying its serial number in the list. If an error or field is displayed instead of the number, check the installed drivers in Windows Device Manager. Next, click select and specify the path to the folder with the unpacked firmware.
At the bottom of the program window, there are three firmware modes that depend on your goals: Clean all erases data completely, save user data tries to save files (not recommended when changing region), and clean all and lock lock locks the bootloader back.

Interrupting the firmware process through Fastboot at the stage of writing the system or boot partition is guaranteed to bring the device down, requiring intervention in the hardware to restore.
- 🚀 Fastboot mode allows you to correct bootloader errors and restore broken systems.
- 💻 The computer must have a stable power supply, the use of a laptop on a battery is undesirable.
- 🔒 Blocking the bootloader after installing global firmware on the Chinese device is impossible.
- ⏳ The process can take 300 to 600 seconds, do not turn off the cable before the time.
Solving mistakes and problems
During the firmware process, users often encounter various errors, the codes of which are given out by the Mi Flash utility. For example, the Missmatching image and device error indicates an attempt to install firmware from another model, in which case you need to recheck the code name of the device (for example, cepheus for Mi 9) and download the corresponding image.
Another common problem is the Anti-rollback bug, which is a security mechanism that prevents rollbacks to an older version of Android or MIUI if the security version counter has been updated, and it is impossible to get around this limitation by software methods and requires replacing the memory chips.
💡
If your computer stops seeing your phone during firmware, try changing it. USB-port on the motherboard (back of the system unit) and use the cable without breakage.
You can also experience a situation where the phone hangs on the Mi logo after firmware. In most cases, re-entering Recovery and executing the Wipe Data / Factory Reset command helps. If this does not help, it may be damaged partition persist or modem, which requires re-flashing with the mandatory cleaning of all data.
