Modern Xiaomi smartphones, which are based on MIUI shells or the latest HyperOS, receive regular security and functionality improvements. The most convenient and safe way to install a new version of the software is OTA technology, or Over-The-Air. This method allows you to download and install the update package directly via a mobile network or Wi-Fi, without requiring a connection to a computer and the use of complex tools like the Mi Flash Tool.
The “over-the-air” upgrade process is fully automated, but requires a few simple conditions to be met to complete successfully. Device owners need to understand how to properly initiate update searches, what to do if the system says there are no updates, and how to avoid common bugs. OTA-The packet can cause the device to reboot cyclically, so it is important to ensure stable power supply and not interrupt the process.
In this article, we will examine in detail the mechanism of the built-in updater, examine the differences between stable and beta versions, and provide solutions to the typical problems that users face when trying to update their gadget.
What is it? OTA-Update and how it works
OTA (Over-The-Air) is a method of wirelessly delivering and installing software updates to mobile devices. Unlike manually updating through a computer, where the user must download the firmware and run the process through special software, OTA runs in the background. The system service periodically polls the manufacturer's servers, checking for a new version of the software for a particular model and region.
When the server confirms the availability of the update, the user receives a notification. The mechanism of operation involves loading a special archive containing only modified parts of the system or the full image, depending on the type of update, which saves traffic and time. After downloading, the system checks the integrity of the files and, after receiving permission, reboots to a special recovery mode for installing patches.
It is important to understand that OTA-The incremental packages are divided into two main types: incremental and complete. Incremental only contain changes between the current and new versions, taking up less space. Full packages represent the complete image of the system. Xiaomi often uses a hybrid approach, first offering a small package, and if errors occur, offering to download the full image.
⚠️ Note: If your smartphone has been unlocked (bootloader unlocked), the system may not receive automatic notifications of new versions.This is standard security behavior, in which case you will need to manually check or install firmware through the computer.
Preparation of the smartphone before the installation
Before you start the upgrade process, you need to make sure that the device is ready for proper operation, first of all, this concerns the battery charge. Although modern algorithms block the installation at low charge, it is recommended to have at least 50-60% of the power. The process of flashing the system partition requires stable voltage, and a sudden shutdown can be fatal.
The second critical aspect is the availability of space in internal memory. Even if the update archive itself weighs 2-3 GB, the system requires additional space to unpack temporary files and back up critical data. The recommended free amount should be at least twice the size of the downloaded file.
☑️ Preparation for OTA-renewal
It is also worth taking care to back up important data. Although a regular update over the air should not affect user files (photos, contacts, applications), software failures do happen. Using the Xiaomi Cloud service or locally storing data on a PC will be a reasonable precaution.
Step-by-step: how to start the update
The process of activating the search for updates in the shells of Xiaomi is as simplified and unified as possible for all models. However, the path to the menu may vary slightly depending on the version of Android and the interface.
- Open the Settings app on the home screen or in the notification curtain.
- Find the About phone item (usually at the top of the list or in the General Settings section).
- At the top of the screen, you'll see the logo of the current version of MIUI or HyperOS. Click on it.
- The system will automatically contact the server and start checking, and if an update is found, the Download button will appear.
Once the boot is complete, the notification will appear in the background and the Reboot button will appear. Pressing it will initiate the device to reboot to Recovery mode, where the installation will take place. The screen will go out, the logo will appear, and then animation of the process. Do not press any buttons at this point and wait for the phone to automatically turn on.
💡
If the update button is inactive or hidden, try to quickly click on the MIUI version logo several times in the About Phone menu – this will open the extended bootloader menu.
In some cases, especially when switching between major versions of Android (for example, from Android 13 to 14), the system may require additional confirmation or manual selection of a firmware file if the automatic path is blocked by regional restrictions.
Hand-mounted OTA-Packages via Recovery Menu
There are times when the automatic updater doesn't see the new version, even though it's already out for your region. OTA-a package manually from an official website or proven resources and install it through a hidden menu.This method often helps when the update comes in waves and your account has not yet been in the priority queue.
To implement this method, download the.zip extension firmware file that matches your model. Place it at the root of internal memory. Next, go to Settings → About Phone → MIUI version. Click the logo several times until "Additional Features Enabled" appears.
In the menu that opens (three dots in the top corner), select Select a firmware file. Specify the path to the downloaded archive. The system will check the file and suggest that you start installing. This method allows you to update forcibly, bypassing the server queue.
| Parameter | Automatic OTA | Manual installation (Local) |
|---|---|---|
| Source of the file | Xiaomi server | Downloaded by ZIP user |
| PC requirement | No. | Preferably for downloading |
| Data retention | Yes (full) | Yes (when choosing Clean Install - no) |
| Difficulty | Minimum | Medium |

Common mistakes and ways to solve them
Users often hear the message “No updates were received” or “No updates” and this may be due to the overload of Xiaomi servers in the early days of the release of the new version. DNS-server in Wi-Fi settings at 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
Another common problem is an installation error when the progress bar is over and the phone returns to the menu unchanged, most often caused by space shortages or damage to the system updater cache. Try clearing the Update app cache through the app menu or restarting the device to safe mode before you try again.
If the error is repeated, the integrity of the system files may be compromised due to root rights or a modified bootloader, in which case the regular OTA is often blocked by developers, and the only solution is to install the firmware cleanly.
Differences between Stable, Beta and Developer versions
Xiaomi’s ecosystem offers several branches of software development. Stable is designed for the mass user. It passes long tests, contains minimal errors and updates less often, but guarantees stable operation of the main functions.
The Beta or Developer branch is created for enthusiasts and testers, where new features appear first, but there is a risk of encountering bugs, overheating or unstable application performance, updates for these versions come out weekly (or even more often) and require more careful attention to backup.
Switching between branches (like Beta to Stable) often requires a complete data cleanup, even if the Android versions match.The system warns of this, but users often ignore the message, leading to conflicts in the system.
💡
Use a stable version of MIUI/HyperOS for everyday work to avoid data loss and unpredictable smartphone behavior.
