How to properly upgrade your Xiaomi phone: the full guide

Modern Xiaomi smartphones require regular attention to software to function stably and safely. Device owners often face the need to install a new version of MIUI or upgrade to the latest HyperOS, but do not know where to start this process. Update errors can lead to data loss or even bricking of the gadget, so it is important to act consistently and consciously.

The process of installing new versions of the operating system is not always smooth, especially if you use custom firmware or global versions on Chinese devices. In this article, we will discuss all methods in detail, from regular updates “over the air” to manually installing archives through Recovery, you will learn how to prepare the device, what data you must save and what to do if the download is stuck on the logo.

Before you take action, you need to understand the difference between the types of updates and their impact on the system. OTA-Over-The-Air is the standard method the phone offers when a notification appears, but there are more advanced ways that require user intervention, such as using the File Choice menu or Fastboot mode. Understanding these differences will help you choose the best path for your situation.

Preparation of the smartphone to install a new version of the software

Any manipulation of system files requires pre-preparedness, which is often ignored by users in a hurry.The first and most critical step is to create a full backup of the data, as the installation process can initiate a complete reset.Even if you plan to upgrade without cleaning, the risk of failure is always there, and having a backup on an external medium or in the Google Drive cloud will be your insurance policy.

The second important aspect is to ensure a stable power supply: the battery needs to be charged at least 60%, and ideally 100%, so that the device does not turn off at the most inopportune time. Interrupting system file recording due to battery discharge is one of the most common reasons why the phone stops booting and requires difficult recovery through service centers.

⚠️ Warning: Before starting the procedure, be sure to free up at least 10 GB of free space in internal memory. Lack of space can lead to errors in unpacking the archive and interrupting the installation.

It is also worth checking the status of the service. To download heavy service packs, which often exceed 3-4 GB, it is recommended to use stable Wi-Fi. Mobile Internet can be unstable, and interrupting the download at the final stage will force you to start the process again, consuming traffic and time.

Don't forget to also check your device model and current firmware version. This information is in the Settings menu. → Knowing the exact model (e.g. Redmi Note 12 Pro or Xiaomi) 13T) It is necessary if you decide to download the firmware manually from official resources, since files for different regions and modifications are not compatible with each other.

Automatic updates through system settings

The easiest and safest way to update the software is to use the built-in update engine.This method is ideal for most users who want to just get new features and security patches without unnecessary movements.The system itself checks Xiaomi servers and offers an affordable version that is compatible with your region and configuration.

To start the check, go to Settings → About Phone and click on the big MIUI or HyperOS version icon. If the update is available, you will see the Download or Update button. Once you download the archive, the phone will suggest restarting and start installing, which can take 5 to 15 minutes depending on the device's memory speed.

Sometimes the notification doesn't come, although the new version is available on other devices in your model, so you can try clicking on three dots in the corner of the screen (in the update menu) and select "Select File", but you should just wait a couple of days for the start. The servers update the information gradually, and your device may be in line later than others.

💡

If the update doesn’t come, try changing the region in settings (Settings → Additional settings → Region) to a country where the release occurred earlier, such as India or Indonesia, and then check the updates again.

It's important to understand that the automatic method updates the system in stages, so if you have a very old version, the system may suggest upgrading to an intermediate version first, and then the final, up-to-date build will be available, which is a normal behavior designed to minimize the risk of conflicts in system files.

Manual installation of firmware through Recovery Mode

For more experienced users or in situations where automatic updates don’t work, there is a manual installation method, which allows you to install a specific version of the firmware that you downloaded yourself from trusted sources, such as the official miui.com website or authorized mirrors, which gives you full control over the process and allows you to, for example, roll back to a more stable version or move from Chinese firmware to global (with the bootloader unlocked).

The firmware file should have a.zip extension and weigh about 3-5 GB. Once downloaded, place it in the root of the phone's internal memory (not in the folder, but immediately in the main directory) so that the system can easily find it. Rename the file to something simple, such as update.zip, to avoid recognition errors due to special characters in the title.

Then we go back to the update menu (Settings → About Phone → OS version). Click on the three dots in the upper right corner and select "Select File"; the system will open the file manager where you need to find your archive and confirm the selection; the phone will check the integrity of the file and, if all is correct, will suggest a reboot for installation.

⚠️ Note: When you manually install firmware from a higher version to a lower version (rollback version), the data will be deleted automatically. Make sure you have a fresh backup before starting the procedure.

There is also Recovery mode, which is called by a combination of buttons when the phone is off (usually Volume up + Power).In this menu, you can choose Wipe Data for full cleaning and Connect with MIAssistant for connecting to the computer, but for a simple upgrade, the method through the settings described above is enough.

Update via computer and Mi Flash tool

The most radical and powerful method is to use a computer and the Mi Flash Tool, which requires a smartphone to be Fastboot and an unlocked bootloader, which is used to completely flash the device, recover from major crashes, or change the firmware region from China to Global.

You will need to work: a computer with Windows OS, USB-High quality cable, Xiaomi drivers USB The process is this: you download a firmware image (.tgz format), unpack it, run Mi Flash, connect the phone in Fastboot mode (clutching Volume Down). + Power) and choose the path to the folder with the firmware.

In Mi Flash, it is important to choose the right firmware method at the bottom of the window: Clean all will clean the phone completely, save user data will try to save data (but can cause errors when changing the region), and clean all and lock will block the bootloader back, which can lead to problems if you are running the wrong version of the software.

Using Mi Flash guarantees a clean, litter-free system from previous versions, but requires high care. Incorrect firmware (for example, for another model) can permanently disable the device. Always double-check the codename of the model, for example, vayu for the POCO X3 Pro or rosemary for the Redmi Note 11 Pro, before starting the procedure.

Frequent errors and ways to fix them

Even if you follow all the instructions, users can encounter errors, and one of the most common is "Failed to check updates." This is often due to problems on the server side of Xiaomi or an unstable Internet connection. DNS-server in Wi-Fi settings on 8.8.8.8 or using mobile internet instead of Wi-Fi.

Another common problem is the message "File can't be verified" when manually installed, which means that the downloaded archive is damaged or does not match your current version of the system, for example, you can not just switch from Android 14 to Android 13, or from Chinese firmware to global without unlocking the bootloader and completely reset, the security system will not install incompatible code.

• 📉 Memory Lack: An error occurs when less than 5-7 GB Solution: Delete photos, videos or apps before updating.
• 🔋 Weak charge: If the battery is dead in the process, the phone will go into a reboot cycle.Solution: leave it on charge for a few hours, sometimes it recovers itself.
• 🌍 Regional mismatch: Attempting to put global firmware on a Chinese machine without unlocking.Solution: Requires unlocking the bootloader through the official website.

If the phone is stuck on the bootloop, don't panic. Try recovery mode. + Power) and select Wipe Data, which will return the device to factory settings and often solve the problem of software conflicts.
