How to Update Xiaomi: A Complete Firmware Guide

Modern Xiaomi, Redmi and POCO smartphones require regular software updates to ensure stable operation and security. Device owners often face the need to install a new version of MIUI or the latest HyperOS operating system, but do not know where to start the process.

The procedure can be performed in a number of ways, from a standard air-to-air update to a complex computer flashing, depending on the current state of the gadget and the user's goals, and sometimes the automatic method fails due to regional limitations or download server errors, which requires manual intervention.

In this article, we will discuss all the current methods of software installation, necessary tools and precautions: you will learn how to prepare the device, where to download official files and what to do if the process is interrupted.

Preparation of the device for the installation of new firmware

Before any manipulation of system files begins, a number of preparatory steps must be taken: ignoring these steps can lead to loss of personal data or software errors. Backup is the most important step, since a complete reset is often a prerequisite for changing the OS version.

Make sure the battery is at least 60-70%, the process of writing data to the phone's memory is energy intensive, and a sudden shutdown at a critical moment can turn the device into a "brick." Also free up internal memory: it can take 5 to 10 GB of free space to download and unpack files.

Check if you have all the accounts you need. If you plan to use cloud services, make sure your Mi Account is active and synced, which will allow you to quickly restore contacts and photos after the procedure is completed.

⚠️ Note: Before starting the procedure, be sure to remove the memory card SD, In rare cases, the system may attempt to write system files to an external medium, resulting in formatting and data loss.

Automatic update via settings (OTA)

The easiest and safest way to get a new version of software is to use the built-in OTA (Over-The-Air) mechanism, which does not require a connection to a computer or special knowledge, but the system itself checks for updates and suggests installing them.

To start the process, go to Settings → About Phone. Click on the large icon of the MIUI or HyperOS version in the center of the screen. The device will contact the server and check the relevance of the software. If a new version is found, the Download and Update button will appear.

Sometimes the update doesn't come to all users at once. It's normal to roll out in stages. If you already have firmware on the official website and you don't, you can use the manual check function. Click on the three dots in the top right corner and select "Select firmware file" (not available in all versions) or just wait.

It is important to ensure a stable connection to the Internet. interrupting the download of a large amount of data (3-5 GB) can damage the boot packet. Use a reliable Wi-Fi network, avoiding public access points with browser authorization.

Manual installation via Recovery Mode

If the automatic method does not work or you want to update before the official mailing, the manual installation method is used. You will need to download the firmware archive with the.zip extension from the official website or a verified resource. The file must correspond to your model and region (Global, EU, CN).

Put the downloaded file in the root of the phone's internal memory. Don't put it in folders, use the main directory. Next, go to Settings → About Phone and tap on MIUI. Press three dots and select "Select firmware file." The system will check the integrity of the archive and suggest rebooting.

If the standard menu path is not available, you can use Recovery mode. Turn off your phone and press the Volume Up + Power button combination. From the menu that appears, select a language (usually English or Chinese) and click Install Update.zip (or similar).

⚠️ Note: When switching from Chinese to Global (or vice versa) through Recovery, a full Wipe Data reset is often required.

Firmware through computer and Mi Flash Tool

The most radical and reliable method that allows you to restore the device even in the event of serious errors, USB-This is a special tool, Mi Flash Tool, which is necessary if the phone does not load or you need to change the region.

Download the Fastboot ROM archive (.tgz extension) and unpack it on your computer. The path to the folder should not contain Cyrillic or spaces. Run the Mi Flash Tool on behalf of the administrator. Connect the phone turned off by pressing the Volume Down + Power button until the Fastboot logo appears.

In the Mi Flash Tool, click the Refresh button to let your computer see the device. In the bottom corner, select the mode of operation. The Clean all option will delete all data completely, Save user data will try to save it (but can cause errors when changing regions), and Clean all and lock will block the bootloader. Clean all is recommended for most cases.

Press the Flash button and wait until the process is over. The green success indicator will report success. The phone will automatically reboot, and the first boot can take up to 10-15 minutes. Do not interrupt the USB connection at this point.

💡

Use the original. USB-cable and connect the device directly to the PC motherboard (back ports), avoiding USB-This will eliminate data transmission errors when you're firmware.

Solving Common Errors in Updating

There may be a number of failures during the upgrade process, and one of the common problems is a loading error or a logo hover. If the phone is stuck in the boot phase, try to force the reboot by holding the power button on the phone. 10-15 seconds.

If you see a message that says "failed to update," check the integrity of the firmware file. You may have downloaded a broken file. You may want to try to download the file again, preferably from another source or using a different browser. You may also want to make sure there's enough space on the disk.

Another common problem is the lack of updates for specific models: smartphones older than 3-4 years may not receive official updates to HyperOS, remaining on the latest version of MIUI.

• 📱 Error 10: Access rights issue or system files corruption – Fastboot flashing required.
• 🔋 Phone turns off during upgrade: Battery is dead or power controller is faulty - charge the device and try again.
• 🌐 Network error in OTA: Change. DNS 8.8.8.8 or use mobile internet instead of Wi-Fi.
• 🔒 Blocked bootloader: Some firmware installation requires unlocking through Mi Unlock, which is impossible without an account binding in 7 days.

⚠️ Note: If the phone is constantly restarted after the update (bootloop) and is not included in the Recovery menu, the system partition is probably blocked. In this case, only a complete flashing through the Fastboot will help with cleaning all data.
