Update Android on Xiaomi smartphones: 4 proven ways + error solving

Updating the operating system on Xiaomi smartphones is a process that many users put off “for later” in fear of losing data or encountering errors. Meanwhile, the latest versions of MIUI and Android bring not only new features, but also critical security fixes, performance optimization and support for modern applications. For example, switching from MIUI 12 to MIUI 14 can increase battery life by 15-20% due to improved management of background processes.

In this article, we’ll look at all the current ways to upgrade, from standard OTA (over the air) to manual firmware via Fastboot and Recovery. Particular attention will be paid to the typical problems: when the system “hangs” on the Mi logo, gives an error “Can’t verify update” or simply does not find new versions. Also, you will learn how to prepare your phone for an update to avoid losing photos, contacts and other data. If your Redmi Note 12 or POCO F5 has not received updates in a long time, this is the guide for you.

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

Before you start updating, you need to perform a few critical actions, neglecting them can lead to a blink (complete failure) of the device or loss of personal data, especially for manual firmware methods.

• 📱 Check the model and version MIUI: Go to Settings. → Write down the exact name of the model (e.g. Redmi Note 11 Pro). 5G) and the current version of the firmware (for example, MIUI 13.0.12 Global.This will help you choose the right firmware file.
• 🔋 Charge the battery to at least 60%: When upgraded via Recovery or Fastboot, discharging during the process may cause system files to be damaged.
• 📡 Connect to stable Wi-Fi: Download firmware "over the air» (OTA) It can take anywhere from 10 minutes to an hour depending on the file size (usually 1.5-3 GB.
• 🔐 Backup: Use the built-in Backup app (Settings) → Additionally. → Backup and reset) or third-party services like Google Drive to save contacts, SMS and settings.
• 🧹 Clear the cache: Go to Settings → Warehouse → Clear the cache. This will eliminate possible conflicts when installing the update.

⚠️ Note: If your smartphone is unlocked (custom installed) TWRP or root rights, official OTA-updates can lead to a cycled bootloop (infinite reboot). In this case, use only manual firmware methods.

For Xiaomi models based on Android 13+ (such as Xiaomi 13T or POCO X5 Pro), it is recommended to disable the “Optimized Charging” function in the battery settings before updating.

Method 1: Automatic Air Update (OTA)

The easiest and safest method is to update through the built-in system. OTA (Over-The-Air! is suitable for 90% of users and does not require technical skills. OTA-Packages are gradually (called staged rollout), so even if the update is already announced, it may appear on your device in 1-2 weeks.
