How to update MIUI on Xiaomi smartphone: 5 proven ways + error solving

Updating MIUI firmware is a key process for Xiaomi smartphone owners that not only adds new features, but also fixes critical vulnerabilities, improves performance and extends the life of the device. However, improper actions during an upgrade can lead to a phone “brick” (complete failure), data loss or software failures. In this article, we will discuss all the current ways to update MIUI — from standard OTA to manual firmware through Fastboot — and also tell you how to avoid typical errors and what to do if something goes wrong.

MIUI is a feature that Xiaomi has been releasing updates for its devices longer than many other manufacturers: even budget models often receive updates within 3-4 years of release. But not all users know that in addition to automatic updates “over the air”, there are alternative methods to install fresh firmware manually – for example, if your region has not yet received an OTA or you want to move to a global version from the Chinese. We analyzed the user experience on the 4PDA and XDA-Developers forums, as well as official Xiaomi recommendations to collect the most complete and secure guide.

1.Refreshment preparation: what to do before installing a new firmware

Before you start updating, be sure to follow a few critical steps, neglecting preparation is the main cause of most problems after the firmware, from losing photos to not being able to boot the system.

First, check the current MIUI and your smartphone model. You can do this from the Settings menu → About Phone → MIUI version. Write down or take a picture of this data, which you will need to choose the right firmware. For example, the Redmi Note 12 Pro+ and Xiaomi 13 Ultra use different update files, and trying to install incompatible firmware will lead to an error.

Make a backup copy of the data (photos, contacts, messages)

Check the battery (minimum 50%)

Ensure a stable Internet connection (Wi-Fi or mobile network with unlimited traffic)

Record the current version of MIUI and smartphone model

Disable antivirus and optimizers (they can block installation)

Connect the original cable USB (If you plan to run through a PC)-->

Pay special attention to backup. Even if the update is successful, sometimes it will reset or disappear data from some applications. Use the built-in Settings feature → Additional → Backup and Reset → Local backup or third-party services like Google Drive (for contacts and photos) and Mi Cloud (for notes and SMS). If you upgrade from Chinese firmware to global (or vice versa), without backup, you will lose all data – this process implies a complete reset.

Also check if there is enough free space on the device. An over-the-air (OTA) update usually requires 1-2 GB of free space, and up to 3-4 GB for manual installation through Recovery. If there is not enough memory, transfer files to a memory card or PC, or remove unnecessary applications.

Method 2: Automatic update via OTA (the easiest method)

The safest and most recommended way Xiaomi is to upgrade over the air (Over-The-Air, or OTA), which is suitable for most users, because it does not require technical skills and minimizes risks.

To check for updates:

• 📱 Open the Settings. → The phone. → Updating the system.
• 🔍 Click the "Check Updates" button».
• 📥 If the update is available, the system will prompt you to download it.
• ⚙️ After download, click “Install” and wait for the device to restart.

The installation time depends on the size of the firmware and the model of the smartphone. Usually the process takes 5-15 minutes. Do not interrupt it or turn off the phone, even if the screen goes out for a long time, this is normal. If after a restart the system suggests repeating the installation, agree: sometimes the update is installed in two stages.

💡

If the update doesn’t come long, try changing the region in the MIUI settings. Go to Settings → Additional → Region and select, for example, India or Indonesia – these regions often get updates before others.

If OTA-No updates are available, the reasons may be as follows:

• 🚫 Your model is no longer supported (e.g. Redmi 5 or Mi). A1 No updates after 2022).
• 🌍 You use informal or custom firmware (e.g. LineageOS or Pixel Experience).
• 🔒 The device is blocked by the operator (for example, smartphones purchased in communication salons).
• 📡 Problems with Xiaomi servers (it is recommended to wait 1-2 days and repeat the check).

Method 2: Manual installation via Recovery (for power users)

If automatic updates are not available, or you want to install a specific version of MIUI (for example, switch from Chinese firmware to global), you can use the Recovery installation method. This method requires more action, but allows you to upgrade even without OTA.

To start, download the correct firmware from the official Xiaomi website:

• 🌐 Go to the downloads page MIUI.

⚠️ Note: When installing with Recovery, don’t select “Wipe Data” unless you want to lose all your data! This option is only needed when switching between different types of firmware (for example, from Chinese to global).

Method 4: Fastboot Firmware (for advanced users)

Fastboot is the most reliable way to flash a smartphone if other options don't work, and it's suitable for refurbishing blinked devices, changing the firmware region, or installing custom ROMs. However, this method requires an unlocked bootloader and working with the command line.

To run through Fastboot, you will need:

• 💻 Computer with Windows, macOS or Linux.
• 🔌 Original. USB-cable (low-quality cables can cause errors).
• 🛠️ Mi Flash Tool (you can download from the official website).

Step-by-step:

1. Unpack the firmware archive in a folder without Cyrillic characters (for example, C:\MIUI\).
2. Turn off your smartphone and put it into Fastboot mode, clamping Volume down + Power.
3. Connect your phone to your PC. Make sure the drivers are installed (if not, download the Mi PC Suite).
4. Launch the Mi Flash Tool, press Select and specify the path to the firmware folder.
5. Select firmware mode: Clean All - complete cleanup (remove all data!), Save User Data - saving user data (not always stable), Clean All and Lock - cleaning + lock the bootloader (for official firmware).

⚠️ Note: If you choose Clean All, all data on your phone will be erased, including photos, messages and apps. This method is not suitable for devices with a locked bootloader - trying to flash them through Fastboot without unlocking will lead to an error and a possible blink.

5. Method 4: Update via Mi PC Suite (alternative to Windows)

If you don’t want to work with the command line, OTA-Update is not available, you can use the official Mi utility PC It automates the firmware process via PC and is suitable for most Xiaomi, Redmi and other models. POCO.

Download the program from the official website and follow the instructions:

6. Method 5: Install custom firmware (for enthusiasts)

If you are not satisfied with the official MIUI (for example, due to a lot of advertising or lack of updates), you can install custom firmware like LineageOS, Pixel Experience or ArrowOS. This method requires an unlocked bootloader and is suitable only for advanced users.

Main steps:

7.Typical Mistakes When Updating MIUI and How to Fix Them

Even when you follow instructions, sometimes you have problems, and let's look at some of the most common mistakes and how to fix them.

• 🗑️ Clean the cache in Recovery (wipe cache item).
• 🔋 Calibrate the battery (discharge the phone to 0%, then charge to 100% without interruptions).

💡

If the update has lost sound, the camera is not working or the mobile network is missing, most likely, the firmware was installed incorrectly, in which case only re-running through Fastboot with complete data cleaning will help.
