Owning a Xiaomi smartphone often opens up a wide range of software experiments that are rare in other manufacturers. A procedure known as flashing allows not only a device to come back to life after critical errors, but also to change the firmware region, get a global version of the MIUI shell, or even install a custom operating system. Many users fear this process, considering it the lot of selected engineers, but with a PC and a clear adherence to the algorithm of actions, even a beginner can cope with the task.
It is important to understand that firmware is a deep system operation that completely replaces the device’s software code. Android on your smartphone will be completely rewritten, and all data, including photos, contacts and applications, will be irrevocably deleted if you do not back up in advance.
In this article, we will discuss all available methods for restoring and updating Xiaomi software using a personal computer. We will consider working in Fastboot mode, using the official Mi Flash Tool utility, and also touching on the nuances of unlocking the bootloader. Your task is to read each item carefully, since one wrong command can lead to the need for more complex repairs.
Preparation of equipment and software
Before any manipulations begin, you need to assemble a complete set of tools without which successful firmware is impossible. The main element is a personal computer or laptop running the Windows operating system, since most specialized utilities from Xiaomi do not have versions for macOS or Linux. The computer must have a stable power source so that a sudden power outage does not interrupt the critical process of writing data to the phone’s memory.
Particular attention should be paid to the choice USB-Cheap charging cables often do not support data transmission or have high resistance, resulting in a voltage drop during firmware. Use the original cable or certified standard-enabled counterpart USB 2.0 or higher. Also make sure the port is USB on the motherboard is serviceable, and it is desirable to connect the device directly, bypassing USB-hubs.
- 🔌 Original. USB-cable or quality analogue with data transmission support.
- 💻 PC with Windows operating system (7, 10 or 11) and free disk space.
- 🔋 Charged smartphone (minimum 60%) and stable connection to the power grid.
- 📥 Installed drivers ADB and Fastboot, and USB-Qualcomm or MediaTek drivers.
⚠️ Warning: Use of damaged or too long USB-cable is the most common cause of firmware errors that lead to "bricking" of the device.
In addition to the hardware, you will need to download the current firmware image. The official files are available on the portal miui.com or third-party verified resources like XiaomiFirmware. It is important to choose a file for your model, since the firmware from Redmi Note 10 will not work for Redmi Note 10 Pro, even if they are visually similar. The firmware file usually has the extension.zip or.tgz, and it must be unpacked into the root of the disk or folder with a short way to avoid encoding errors.
Unlocking the loader: a mandatory stage
Modern Xiaomi smartphones come with a locked bootloader, which is a security measure to prevent uncertified software from being installed. Unlocking is mandatory for Fastboot flashing (a low-level recording mode). If you plan to just upgrade your phone through Recovery, this step can be skipped, but it is necessary for a full PC flashing.
The unlocking process requires you to link your Mi Account to your device and wait 7 to 30 days, depending on the company's policy at the time of application. Once you get permission from the Mi Unlock app on your PC, connect your phone in the appropriate mode and execute the unlock command. This action will automatically perform a full Wipe Data reset, so take care of the backup.
If Mi Unlock is an error, check if you are logged in to the same Mi Account on your PC and phone. USB-port or cable. Sometimes it helps to re-assign the device in the settings" ->"Mi Unlock status".--> It is worth noting that unlocking the bootloader can lead to a loss of warranty in some regions, although in most cases Xiaomi is loyal to this procedure. After unlocking when booting the phone will appear warning that the device is not protected, and booting the system may take a while to get a new one. 5-10 seconds more than usual. 🔓 Unlocking gives full rights to manage device memory partitions. ⏳ The waiting period for the company’s permission may be up to 30 days. 🗑️ The unlocking process is always accompanied by the complete deletion of user data. 🔐 Without the unlocked bootloader, installing global firmware on Chinese versions is impossible.
Fastboot and Recovery For successful firmware, you need to clearly distinguish between the device’s modes of operation, since each is designed for its own tasks. Recovery mode is a recovery environment that allows you to reset settings, clean up cache or install updates through the menu. However, for deep flashing through the PC, we need Fastboot mode, which allows you to transfer commands and data directly to the controller memory. To get into Fastboot mode, you need to turn off the smartphone and pinch the button combination Volume Down. + Nutrition before the appearance of the image of a hare repairing an android, or inscriptions FASTBOOT. In this mode, the screen may appear dull or black, but the connection to the PC will be accompanied by the characteristic sound of the system. Recovery Mode Fastboot Mode EDL Mode Reset, update to OTA Firmware via PC, unlock Rescue "bricks", deep repair Entry Volume Up + Power Volume Down + Power Special. combination or test points Access to PC Limited (ADB) Full (Qualcomm/MTK Port) There is also an EDL mode (Emergency Down), which is used to restore completely non-functional devices ("Strongine Mode Powering"Spec. combination or test points for use on the phone, which is a special tool for the user of the device). After installing the utility and unpacking the archive with the firmware, launch the executable file on behalf of the administrator. In the program interface, press the Refresh button to make sure that the computer sees the connected device in Fastboot mode. If the device is determined, its serial number will appear in the list. ☑️ Checklist before firmwareCopied path to the folder with firmware (without file name.bat)Phone transferred to Fastboot mode Drivers installed and running Battery charged more than on 60%Mi Flash Tool launched from administrator: 0 / 5 Choose the path to the unpacked firmware folder by pressing the Select button. It is important to specify the folder where the image file and the script are located. flash_all.bat, Once you select a path at the bottom of the window, you will have three options: clean all, save user data, and clean all and lock). The safest and most recommended option for changing a region or version of software is clean all. It completely erases data sections and installs a clean system. Use the clean all and lock option only if you return the device to factory condition for sale, but be careful: blocking the bootloader with inappropriate firmware (for example, Global to Chinese apparatus without changing the region) may lead to the inability to download. ⚠️ Warning: Never select the Lock option if you change the firmware region (e.g., with a CN This will lock the device, which can only be removed through paid services or soldering. After selecting the settings, click the Flash button in the top menu. Start a recording process that will appear in the program log in green or yellow. Don't touch the cable or turn off the computer until the success or flash done message appears. 2 before 10 minutes depending on speed USB-Owners of devices imported from China often face a lack of Russian language and Google services. ROM) It solves these problems, but it requires a strict order of action, and the main rule is that you can't just upgrade from Chinese to Global through the update menu, because the regions don't overlap. You need a complete Fastboot flash with the data cleanup. When selecting a firmware file, make sure that the file name contains the region code. MIUI_Global code MI, Chinese — MIUI_CN code CN. It's also important to check the firmware type: Recovery (for an internal update) or Fastboot (for PC firmware, the file has the.tgz extension). We need the second option. Once the global firmware is installed, the device may need to be activated. If the phone is new, there will be no problems. If the device was previously activated with a Chinese account, you may need to log in to the same account to confirm the rights of the owner. FRP (Factory Reset Protection, if the accounts were not deleted in advance. 🌏 Global firmware contains Google services, multilingual interface and notifications. 🚫 Direct update with CN Globally OTA It is impossible to do this only through Fastboot. 📉 After the change of region, some banking applications may stop working due to security checks. 🔄 Always back up before changing the region, as the data will be destroyed.Possible errors and methods of fixing them The firmware process does not always go smoothly, and users may encounter different error codes. One of the most common is the Miss matching image and device error, which means that the selected firmware does not match the model of the device, in which case you need to recheck the model in Fastboot mode (it is displayed in small print) and download the correct file. Another common problem is driver error when the computer doesn't see the phone in Fastboot mode. In Device Manager, the device may appear as "Unknown Device" or"QUSB_BULK". To solve it, you need to manually update the driver, specifying the path to the folder with Xiaomi or Qualcomm drivers, or reinstall the Mi Flash utility with administrator rights. If the firmware process is suspended on a certain percentage (for example, on the 30% or 90%) and no longer moves 10 In this case, you need to interrupt the process, disconnect the cable, remove and insert the battery (if possible), or press the power button on the battery. 10-15 You can reboot a second and then try again. USB-port-line. 📊 What problem did you encounter most often when Xiaomi firmware?Driver error Wrong version of firmwareIncorrect version of firmwareInterrupted connection Everything was successfulNot stitched, I am afraid In case the phone stopped turning on and only the indicator burns or the screen remains black, perhaps the device went into mode EDL. To exit it often requires a service cable ("chick") or short-term closure of contacts on the board. However, if the firmware is interrupted early on, a second firmware attempt via Fastboot (if the phone is included) usually solves the problem. MI If after firmware the phone shows the logo endlessly (Bootloop), try resetting data via Recovery. + Nutrition -> Wipe Data. If that doesn't work, maybe the firmware was damaged or not suitable for your model, in which case you need to repeat the firmware procedure through Fastboot, always selecting the "Clean All" option. Can you flash Xiaomi without unlocking the bootloader? Officially, no if you want to change the region or version of the software (for example, with the CN Globally). Update within a region (e.g. update) MIUI 13 on MIUI 14 inside the Global version) is possible without unlocking through the Recovery menu or Mi Flash in data saving mode, but deep flashing requires an unlocked bootloader. Will the warranty fly after the firmware? Technically, unlocking the bootloader and installing unofficial software can cause warranty service denial, but if you return the original firmware and lock the bootloader back, visually detecting the interference will be difficult. In hardware defects, service centers often meet the challenge if the problem is not software related. Where do you download secure firmware? The most reliable source is the official website miui.com or the portal miuirom.eui. Also popular are proven third-party resources such as XiaomiFirmware or XDA Developers where the community moderates files. Avoid random files on file sharing sites, as they may contain malicious code. 💡Successful firmware Xiaomi depends on 80% of the correctness of the selected firmware file and quality USB-cable, and only 20% of your activity in the program.
