Updates by air (OTA) — standard way of obtaining new versions MIUI or HyperOS on Xiaomi, Redmi and smartphones POCO. However, sometimes automatic updates are delayed, disappear from the menu or the device simply does not see the available firmware. OTA It becomes the only way to get the latest software without a complete flashing through Fastboot or Recovery.

What is it? OTA-Update and why it doesn’t automatically come
OTA (Over-The-Air is a way of delivering firmware updates over the air, without a PC connection. The update file is downloaded to the device over the Internet and then installed in the background or after a reboot, OTA It only contains changes between versions, making it easier and faster to install.
Reasons why OTA It doesn't come automatically:
- 🔄 Phased release: Xiaomi often rolls out updates in waves - first for 1-5% of devices, then for the rest.
- 🌍 Regional restrictions: Firmware for Global, EEA, India and China are coming out at different times, for example, Redmi Note 11 in Russia may receive an update later than in India.
- 🔧 Modified software: If you previously installed custom firmware, changed the region through ADB or have removed system applications, automatic updates may break.
- 📶 Server problems: Sometimes Xiaomi servers are overloaded and updates are temporarily unavailable.
Hand-mounted OTA This allows you to circumvent these restrictions, but requires compliance with two key conditions:
- The update file should be specifically designed for your model and the current firmware version.
- The device must not have critical modifications (e.g. remote) /system or modified build.prop).
💡
Before hand-mounting OTA Check the current version MIUI/HyperOS In Settings → The phone. → Version. MIUI. This will help you choose the right update file.
