Modern Xiaomi, Redmi and POCO smartphones require regular software updates to ensure security and stability. The over-the-air upgrade (OTA) method is the easiest and safest way to install a new version of the system. You don't need a computer, special cables or complex programs like the Mi Flash Tool.
Auto-loading and installation takes 10 to 40 minutes, depending on the weight of the package and the speed of your Internet connection, and it is important that the device is charged at least 60% before the procedure begins to avoid a sudden power outage at a critical moment.
In this guide, we will discuss in detail not only the standard update path, but also hidden methods for activating packets, as well as ways to solve common errors when the server does not see a new version.
Preparation of the smartphone for the update procedure
Before you click Download, you have to do a series of preparatory steps to minimize the risk of bugs and loss of user data. Although MIUI and the new HyperOS are highly fault-tolerant, neglecting the basic rules can lead to failures.
First of all, make sure that there is free space on the disk. The system often requires a volume larger than the size of the installation file itself to temporarily unpack the archives. If there is not enough memory, delete unnecessary videos or transfer the photo to the cloud storage.
⚠️ Note: Before starting the process, be sure to back up important data via Settings → Advanced settings → Copying and recovery: Despite the security of the method, the risk of losing contacts or messages is always there.
It is also critical to check the stability of the connection: if you are using a mobile network, make sure that you have unlimited tariff or have sufficient GB of storage, as the weight of full firmware can reach 4-5 GB.
☑️ Readiness for renewal
Standard method of updating through settings
The official and most recommended way to get a new version of the software is to use the built-in menu. The algorithm of actions is the same for all current models, whether it is the flagship Xiaomi 14 or the budget Redmi Note 13.
Go to the main menu and select Settings, find the About Phone section (some versions may call it About), and in the window that opens, you will see the current version of the operating system and the MIUI or HyperOS logo.
Click on the big system version icon, the device will automatically contact the server and check for available updates. If an update is found, the Download button will appear. After downloading, the system will prompt "Reboot and Update".
💡
Automatic verification is the safest way, as the server itself selects a compatible build for your region and device model.
In some cases, the system can report that “No Updates found” even if the new version has already been released, due to the phased spread of firmware. Xiaomi servers send files to users in small portions to avoid overloading the infrastructure.
Forced inspection and manual installation
If standard search didn't work and the new version is available, you can use manual verification, which often tricks the system into giving the update file ahead of time.
In the About Phone menu, click on the system logo (MIUI or HyperOS) several times in a row (usually 7-10 times), and a pop-up will appear with the message "Additional Updates Features Enabled", and then three menu points will appear in the upper right corner of the screen.
Click on three dots and select "Select a firmware file." Here you'll need a pre-downloaded archive with an update. The file should have a.zip extension and be a full ROM, not an incremental update.
⚠️ Note: The firmware file must be strictly in line with your current version. You cannot roll back to an older version or go from Global to Chinese just by selecting the file».
Use official resources or trusted communities to find current and verified files, and once you select a file, the system will check its integrity and suggest that you start the installation process.

Upgrade Methods Comparison: OTA vs PC
Users often wonder which upgrade method to choose, with each method having its own advantages and disadvantages to consider depending on your situation and technical skills.
Air-to-air updates (OTAs) are convenient because they are simple, you don't have to search for drivers, plug in a cable, or understand complex utilities, but they require a stable Internet connection and often run slower than wired connections.
Using a computer and Mi Flash Tool or Mi PC Suite allows you to perform a clean installation, which means removing all temporary files and debris accumulated over time, an approach that often solves autonomy problems after major Android updates.
| Criteria | Update by Air (OTA) | Update via PC | ZIP hand-mounted |
|---|---|---|---|
| Difficulty | Minimum | Tall. | Medium |
| Data retention | Complete. | Requires reset (usually) | Complete. |
| Equipment required | Only Wi-Fi. | Computer and cable | Firmware file |
| Risk of error | Low. | Medium/High | Medium. |
Choose a method based on your goals. If the phone is stable, OTA is enough. If you see a frieze or a quick discharge, you should consider a PC and a full reset.
Solving Common Errors During Updating
The upgrade process is not always smooth, users may encounter various errors that block the installation of a new version of the system, and understanding the reasons helps to quickly resolve the problem.
One of the most common problems is the message “No updates were received” and this may be due to temporary problems on Xiaomi servers or a malfunction in the network settings of your provider.
Try switching from Wi-Fi to mobile internet or vice versa. Change also helps. DNS-servers in Wi-Fi settings to public addresses from Google (8.8.8.8) or Cloudflare (1.1.1.1).
Another common error is “The file cannot be verified,” which means that the signature of the file does not match the expected one, which happens if the file is corrupted during download or is destined for another model/region.
If the update is stuck during the boot or installation phase (e.g. 99%), don't panic. Let the phone lie down for 15 to 20 minutes. If progress doesn't shift, try to force the reboot by holding the power button for 10 to 15 seconds.
What to do after installing a new version
After successfully installing the update and first booting the system, it is recommended to perform several actions to optimize the smartphone. New versions often change the structure of the files and cache of the applications.
The first thing to do is to give the phone 10-15 minutes at rest with the lock screen on, while the system indexes files and optimizes applications for the new version of the Android kernel.
Check the key features: cameras, Bluetooth, GPS and mobile internet. Sometimes after major upgrades (for example, switching from MIUI 14 to HyperOS), conflicts can arise in the operation of communication modules.
⚠️ Warning: If your phone starts to run out or heat up quickly after the upgrade, don't rush to bring it into service. Give your device 2-3 days to adapt the energy saving algorithms.
It's also worth going to the application settings and checking the permissions, and after major updates, the security system can automatically reset microphone or geolocation access for some programs.
