How to upgrade Xiaomi smartphone to Android 11: official and unofficial ways

Upgrading the operating system to Android 11 on Xiaomi smartphones can significantly improve performance, add new features and improve security. However, the process has a nuance: not all models support this version officially, and incorrect actions can lead to a “brick” of the device. In this guide, we will analyze all working methods from automatic updates via MIUI to manual firmware via Fastboot or Recovery.

It’s important to consider that Xiaomi is gradually rolling back support for Android 11 for older devices, moving to newer versions. For example, the Redmi Note 8 Pro or Mi 9T models officially received the update back in 2021, but for some regions it may not be available due to manufacturer policies. If your device does not see the “over the air” update (OTA), this does not always mean that there is no compatibility – sometimes you need to use workarounds.

In the article you will find:

• 📋 Xiaomi models that support Android 11 officially and unofficially
• 🔧 Step-by-step instructions for each upgrade method (including: MIUI Updater, Fastboot and custom firmware)
• ⚠️ Critical errors and ways to fix them (for example, the error "Cannot verify update" or stuck on the logo)
• 🔄 Alternative solutions for devices that do not receive OTA-update

1. Compatibility Check: Does your Xiaomi support Android 11?

Before you start an update, make sure your Xiaomi model officially or unofficially supports Android 11.The manufacturer releases updates in waves, and even within a single line (like the Redmi Note 9) support may vary depending on the region.

Below is a table with models that are guaranteed to receive Android 11 within the official firmware MIUI (data is up to 2026).If your device is not on the list, this does not mean that you can not completely update – you may need to use custom firmware (for example, LineageOS or Pixel Experience).

If your model is not in the spreadsheet, check it on the official MIUI website or in the XDA Developers community. For example, for the Redmi Note 8 (not Pro), there is an unofficial Android 11 port from third-party developers, but it may contain bugs in the camera or NFC module.

⚠️ Note: MediaTek processor devices (e.g. Redmi Note) 8T or Redmi 9A) Android 11 is often denied official support due to the limitations of the chipset manufacturer, and in such cases, you can only upgrade through custom firmware, but this will require unlocking the bootloader and the risk of losing warranty.

2.Preparing the smartphone for the update: 5 mandatory steps

Regardless of the upgrade method chosen, preparing the device is a critical step, and neglecting it can lead to data loss, disruption, or even a “brickle” of the smartphone.

Create a backup copy of data (photos, contacts, messages)

Charge the battery to 60% or more

Connect to a stable Wi-Fi network (for OTA)

Disable antivirus and optimizers (they can block firmware files)

Make sure there is free space (minimum 3 GB on the internal drive)-->

Pay special attention to backup. Even if the update is successful, some applications (e.g. banking or banking) DRM-protection) may require re-authorization. Use built-in tools MIUI:

1. Go to Settings → About Phone → Backup and Reset.
2. Select Local Backup and mark all the necessary data.
3. Save a copy to Google Drive or external drive.

If you plan to use Fastboot or custom firmware, additionally:

• 🔓 Unlock the bootloader through the official Xiaomi tool (requires binding of the Mi Account).
• 🛠️ Install the drivers. ADB Fastboot on PC (instructions for Windows: official documentation).
• 📥 Download the correct firmware version for your model (for example, for Redmi Note). 9 Pro it could be. joyeuse_global_images...).

⚠️ Note: If you are using Xiaomi.eu or other custom firmware, update via OTA This can lead to a version conflict, in which case it is recommended to perform a clean installation (clean flash) through Recovery.

3. Method 1: Update via MIUI Updater (the safest way)

If your device officially supports Android 11, the easiest way is to upgrade to the OTA (Over the Air) – a method that doesn’t require unlocking the bootloader and saves all the data – but it’s not available for all regions and models.

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

If OTA-Update is not available, but your model officially supports Android 11, you can install firmware through Recovery.

What you need:

• 📦 Firmware in.tgz or.zip format (download from the official website by selecting the Fastboot version).
• 🔌 Cable USB (preferably original).

Instructions:

1. Unpack the archive with the firmware in the folder platform-tools (where fastboot.exe and adb.exe are located).
2. Turn off your smartphone and press the Power button + Volume down to enter Fastboot mode.
3. Connect the device to the PC and check its detection by the command:
4. Launch the file. flash_all.bat (for Windows or flash_all.sh (for Linux/Mac).
5. Wait until the process is complete (usually 5-15 minutes) and the device will restart automatically.

If the script flash_all.bat gives an error, try the manual firmware by command:

fastboot flash system system.img




fastboot flash vendor vendor.img




fastboot flash dtbo dtbo.img
