Installation of official firmware on Xiaomi: all ways and nuances

Installing official firmware on Xiaomi smartphones is a procedure that every device owner sooner or later faces. Whether you want to return the phone to factory settings after a failed experiment with custom firmware, upgrade to the latest version of MIUI or simply restore functionality after a failure - knowing the correct algorithm of actions will save time and nerves. Unlike "gray" schemes with questionable archives from the Internet, official firmware guarantees stability, security and warranty (if it is still valid).

In fact, Xiaomi offers several legal ways to flash the device: through the built-in Update menu (OTA), Recovery mode or low-level Fastboot mode. Each method has its own features, advantages and pitfalls. For example, an Airborne Update (OTA) is suitable for most users, but it won’t help if the system doesn’t boot at all. And installing through Fastboot requires unlocking the bootloader, which automatically resets all data. In this article, we will analyze all the current methods, give checklists for preparation and warn against typical errors that can turn the phone.

Preparation for installation: what to do before the firmware

Before you start installing an official firmware, there are a few critical steps that need to be taken: neglecting it can lead to data loss, locking the device, or even breaking it, starting with the obvious: backup.

Even if you plan to flash your phone through an OTA (over-the-air update), which theoretically shouldn't erase user data, there's always a risk of crashing.

• 📱 Create a backup copy of your contacts, SMS and call logs through Settings → Google → Backup or Mi Cloud application.
• 📁 Copy photos, videos and documents to your computer or cloud storage (Google Drive, Yandex Disk).
• 🔑 Save passwords from accounts (if you do not use a password manager) - after resetting them will have to enter again.
• 📋 Write it down. IMEI phone (click *#06#) in case you need to restore your network settings.

The next step is to check the firmware compatibility with your model. Xiaomi has several product lines (Redmi, POCO, Mi), and the firmware for the Redmi Note 12 is not suitable for the POCO X5, even if they look similar.

• 📦 On the device box (sticker on the back side).
• 🔍 In settings: Settings → The phone. → Model.
• 🛠️ Through ADB, If the phone is not turned on: connect it to the PC and execute the command adb shell getprop ro.product.model

⚠️ Note: If you install firmware for another regional version (e.g. Chinese on a global device), this may cause problems with Google Play Services, the lack of Russian, or blocking some features (e.g., Chinese on a global device, NFC). Always choose the firmware with the correct region code (Global, EEA, China, India).

Method 1: Air-to-air update (OTA) is the easiest method

If your Xiaomi smartphone is powered on and connected to the internet, the safest way to update your firmware is to use the built-in OTA (Over-The-Air) feature.This method doesn't require unlocking the bootloader, doesn't erase user data (most of the time), and is suitable for regular updates.

To check for updates:

1. Open the Settings. → The phone.
2. Tap on the item System Update (or MIUI version on older versions).

• 🚫 You can't just roll back on an older firmware.
• ⏳ If the update weighs more than 1GB, downloading can take a long time.
• 🔋 Make sure that the battery is at least 50% charged, otherwise the system will not allow installation to begin.

If the update isn’t there, even though you’re sure it should be, try:

• 🔄 Restart the phone and repeat the check.
