The process of flashing the Xiaomi Redmi smartphone often becomes a necessity when the device starts to work incorrectly, hangs on the logo or requires resetting regional restrictions. Many users are afraid to start this action because of the risk of turning the gadget into a “brick”, but with strict adherence to the algorithm of actions, the procedure is successful and returns the device to factory speed. Modern tools from the manufacturer allow you to upgrade or restore the system even without deep knowledge of programming.
Before you start to act, you need to understand that flashing is a complete replacement for the software that controls all the components of the phone. Unlike a normal reset that only cleans user data, installing a new firmware affects the system partition and the Bootloader bootloader. That is why it is critically important to prepare the device and the computer to avoid interrupting the recording process, which can lead to the failure of the device.
There are two main ways to restore or update software: through the built-in update menu and using the specialized Mi Flash Tool on the PC. The first option is suitable for scheduled updates when the phone is turned on and running steadily. The second method, which will be discussed later, is professional and is used to recover from crashes, change the region from Global to China or vice versa, and also to roll back to earlier versions of Android.
Preparation of the smartphone and choice of software version
The first step to successfully installing a new operating system is to determine the exact model of your device. There are many modifications to your Redmi line, and firmware designed for one version of the processor or screen can completely disable another. Find the exact name of the model in the Settings menu → A phone with a full code name, for example, redmi_note_10_pro.
Once the device is identified, you need to choose the type of firmware. Global versions (Global) have built-in Google services and support for many languages, including Russian. Chinese firmware (China) often comes with more recent features, but lacks Russian language and Google services out of the box, requiring additional customization. It is also important to distinguish between package types: Recovery (update via the phone menu) and Fastboot (complete reinstallation via PC).
Make sure to back up all your important data, as the Fastboot flashing process involves completely formatting your internal memory. Photos, contacts and documents will be permanently deleted. It is recommended to use Mi Cloud cloud storage or sync with your Google account to save contact lists and calendar.
💡
Before starting the procedure, take screenshots of important settings or take a screen photo to quickly restore the usual configuration after installing the new system.
Make sure your smartphone battery is at least 60% power-intensive, and suddenly turning off the device in the middle of the procedure can damage the partition table. Use the original USB cable preferably connected to the USB 2.0 port on the computer motherboard to ensure connection stability.
Unlocking the bootloader (Bootloader)
Xiaomi’s official policy requires unlocking the bootloader to allow firmware installation via Fastboot. Without this step, the Mi Flash Tool will refuse to write data, giving an authorization error. The unlocking process takes time: after submitting an application in the Mi Unlock application, you often need to wait 7 to 168 hours before the server allows unlocking.
To start the procedure, link your Mi Account to your device. Go to Settings → About Phone → MIUI version and click a few times on the system logo to activate the advanced features. Then, in the Developer Menu, include “Debug by USB” and “Unlock the bootloader.” After that, enter your Mi Account details in the corresponding menu.
⚠️ Attention: Unlocking the bootloader automatically performs a full data reset (Wipe Data). All files on the internal drive will be destroyed at the time of unlocking, so (backup) is mandatory.
After waiting, the server will turn off the phone and enter Fastboot mode, holding the power and volume buttons simultaneously. Connect the device to your PC, launch the Mi Unlock Status or Mi Unlock Tool utility, and follow the instructions on the screen. Successful unlocking will be confirmed by the message "Unlocked successfully" and the appearance of the android-fixing hare when you turn on the phone.
Installation of drivers and preparation of PC
The computer must correctly recognize the smartphone in different modes of operation. This requires the installation of a full package of Qualcomm or MediaTek drivers (depending on the processor) and specific ADB-Without the right drivers, the Device Manager will show unknown hardware and communication with the phone will be impossible.
Download and install the latest version of the Mi Flash Tool, an official tool of Xiaomi engineers that provides secure partition writing, and you’ll need an archiver (like 7-Zip) to unpack your downloaded firmware, as files are often shipped in.zip or.tgz format.
Check the path to the firmware folder. It should not contain Cyrillic characters or spaces, otherwise the program may not see the files. C:\mi_rom\, And you can unpack the contents of the archive right there, and inside the folder you have to have.bat files and folders with partition names (boot, system, recovery).
| Component | Appointment | Where to find out. |
|---|---|---|
| Mi Flash Tool | The main firmware program | Official MIUI Forum |
| ADB Drivers | Drivers for debugging mode | |
| Qualcomm/MTK Driver | Chipset drivers | Chip manufacturer's website |
| Firmware Archive | Operating system files | miui.com / xiaomirom.com |
The process of firmware through the Mi Flash Tool
When all (preparatory work) is complete, you can move to the process itself. Put your smartphone in Fastboot mode: the device turned off, press the volume button and, holding it, connect the USB cable to the computer. The Fastboot logo should appear on the smartphone screen (often with the image of a rabbit).
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button and your device with the corresponding serial number should appear in the list. If the device does not show up, check the Windows Device Manager - the Android Bootloader Interface should be in the USB Controllers section. If there is an unknown device, reinstall the drivers manually.
☑️ Checklist before the start of the firmware
Choose the path to the firmware folder by clicking on the "Select" button. At the bottom of the window, select firmware mode. For a clean installation without saving debris, choose clean all. This mode completely erases all partitions and writes new ones. The save user data option will try to save user files, but it is less stable when changing Android versions.
Press the Flash button to start the process, and the log window will run lines of code showing the progress of each partition's recording, and it is strictly forbidden to turn off the cable or interrupt the computer's power at this point, the entire process takes 200 to 600 seconds, and when it's over, the status will be marked "success", and the phone will automatically restart.
⚠️ Warning: If you get a red line with an error in the firmware process, don't panic. Most often, the problem is the cable. USB, Try reconnecting the cable to another port and repeat the procedure.
Solving common mistakes
Even with careful follow-up, technical difficulties can arise, and one of the most common mistakes is “Miss matching image and device.” This means you’re trying to flash firmware that isn’t designed for the model (like the firmware from Redmi Note 9 to Redmi Note 9 Pro).
A Flash Error error or process getting stuck at a certain percentage often indicates connection problems.Use the original cable that comes with the bundle and plug it directly into the ports on the back of the system unit, avoiding the problem. USB-The Windows antivirus or firewall can also block the Mi Flash Tool, so you should temporarily disable them.
What to do if your phone is in an endless reboot?
In some cases, the computer simply does not see the phone in Fastboot mode. Check Device Manager: if there is a device with a yellow exclamation mark, right-click on it, select Update Driver → Select from the list of available drivers → Android Bootloader Interface. This action will force the desired driver to install.
First start and initial setup
After a successful firmware, the first run of the system can take much longer than usual, from 5 to 15 minutes. This is normal, as it is the optimization of applications and the creation of a new file structure. The screen can display the MI logo or Android, you should not try to restart the phone at this point.
When you first download, you will be greeted by a welcome window. The system may request a Wi-Fi connection to activate and check for Mi Account lock. If you have changed your firmware region (e.g. from China to Global), make sure you select the correct time zone and language. Global versions will require a Google account login.
💡
The first run after flashing is the longest. Don't interrupt it, even if it looks like the phone is getting stuck. Let the system complete the internal partitioning setup.
It is recommended to check the Android version and the date of the security patch in the settings immediately to make sure that the version you planned is installed, and it is also worth checking the main modules: camera, sound, sensor and communication modules. If everything is functioning properly, you can restore data from the backup.
