Android Update on Xiaomi Mi 9: All Ways in 2026

The Xiaomi Mi 9, released in 2019, is still a popular smartphone among users who value the balance of performance and price. However, with the release of new versions of Android and MIUI, device owners are faced with the question: how to safely update the firmware to get fresh features, security fixes and improved stability? In this article, we will analyze all the current ways to update the Mi 9 – from standard OTA to manual firmware through Fastboot, and also look at typical errors and their solutions.

It is important to understand that the upgrade process may vary depending on the current firmware version, device regional binding (Global, China, EEA) and bootloader unlock status. For example, if your Mi 9 is running MIUI 12 and hasn’t received an air update in a long time, alternative methods may need to be used. We will describe each step in detail so that even a beginner can cope without risking bricking the device.

1.Preparation for the update: what to do before the start

Before you start an update, there are a few critical steps that need to be taken, and neglecting them can lead to data loss, malfunctioning of the smartphone, or even complete inoperability, starting with checking the current firmware version and compatibility.

Open Settings → About Phone → MIUI Version. Remember or write down the current version (e.g. MIUI 14.0.5 Global). This will help you choose the correct firmware file. Also check the device model in Settings → About Phone → Model – it should match the Mi 9 (cepheus in internal Xiaomi encoding).

• 🔋 Battery charge at least 60%.When upgrading via Fastboot, it is better to connect the smartphone to the charger.
• 📱 Backup all important data (photos, contacts, messages) Use Settings → Google → Backup or third-party services like Titanium Backup (requires root).
• 🔑 Unlock the bootloader (if you plan to install custom firmware). For official updates via OTA or Mi Flash Tool is not required.
• 🌐 Stable Internet connection: Wi-Fi is better than mobile Internet for downloading firmware weighing 2-3 GB.

Pay special attention to the regional version of the firmware. Installing China ROM on a Global device (and vice versa) can lead to problems with the language, Google services or the operation of the NFC module. Check the region in Settings → Additional → Region.

💡

If your Mi 9 doesn't get yours OTA-Updates, check if they are manually disabled in Settings → The phone. → Updating the system → Threefold (⋮) → Update settings. Sometimes users accidentally turn off automatic verification.

Method 2: Manual installation via Recovery
