Modern smartphones require constant attention to software, and Xiaomi devices are no exception. Regular system updates are not just a way to get new features or a changed interface, but also a critical element of protecting personal data. Users often ignore notifications, not realizing that new versions of MIUI or HyperOS fix vulnerabilities through which hackers could access banking applications.
But the firmware process can be fearful for beginners, because the wrong actions can theoretically turn a machine into a brick. In fact, if you follow the algorithm and understand the difference between OTA, Recovery and Fastboot, the risk is minimal. In this article, we will look at all the ways to update software, from standard “over the air” updates to manually installing archives that allow you to save data or, conversely, perform a complete cleanup.
Before you start taking action, you need to assess the current state of the gadget. If your device is stable and the new version of the system does not promise revolutionary changes, do not rush. But if you are faced with bugs, overheating or want to try out innovations, be sure to back up important data before starting any manipulations, as failures when writing memory sectors sometimes lead to loss of information.
Preparation of the device for installation of a new version of the software
The first step is always to diagnose the current state of the system. You need to make sure that the battery is charged at least 60%, and preferably up to 100%, since the process of writing data is energy intensive. Also check the free space in memory: installing a major Android update or shell can require 3 to 5 GB of free space, even if the file itself weighs less.
Internet connection stability is crucial when downloading files. Using 4G/5G mobile traffic is acceptable, but Wi-Fi is preferable because of the lower probability of connection breakdown on large amounts of data. If you plan to manually install, download the firmware file to your computer or external drive in advance to eliminate transmission errors.
⚠️ Note: Do not attempt to interrupt the installation process if the progress indicator is frozen in one place more than one place. 10-15 In modern systems Xiaomi often occurs background optimization of applications, which can take a significant time.
It is also important to check that the selected firmware version is compatible with your region. Global versions differ from Chinese versions (Global) in the set of pre-installed services and support for communication frequencies. Installing the wrong region can lead to inoperability. NFC-modules or banking applications.
☑️ Readiness for renewal
Automatic update via settings (OTA)
The easiest and most secure method for most users is an over-the-air update (OTA), which checks Xiaomi servers for new builds and suggests downloading them, which guarantees data integrity and minimizes the risk of errors, as the file is pre-checked with checksums.
To initiate a manual search for updates, go to the Settings → About Phone menu and click on the MIUI version logo. If the new version is available, you will see the Download button. Once downloaded, the device will prompt you to restart and start the installation, which will take 5 to 20 minutes depending on the CPU power.
Sometimes it happens that the notification doesn't come to all users at the same time, and it's a normal practice of rollout step-by-step, where developers keep track of bug statistics, and if you want to get the update before others, you can use the Three Dots feature in the corner of the screen and select "Select a firmware file" by downloading the pre-downloaded archive.
Manual installation via Recovery Mode
Recovery installation method is required if the automatic update does not come, or if you want to change the firmware region (for example, from Chinese to global). ROM) from the official website or verified resources in.zip format.
Once you download the file, place it in the root directory of internal memory without putting it in folders. Next, go to the Settings → About menu, click on the system version and select three dots in the corner. If you downloaded the correct version (new or the same as the current one), the Select firmware file button will appear.
In the window that opens, find your archive and confirm the action. The smartphone will warn you about the reboot. This method allows you to update without losing data unless you change the region. ↔ Global) requires complete data cleanup, which the system will warn separately.
| Type of firmware | Expansion | Data retention | Difficulty |
|---|---|---|---|
| OTA (Incremental) | .zip (small) | Yes. | Low. |
| Recovery ROM | .zip (full) | Yeah (usually) | Medium |
| Fastboot ROM | .tgz | No (required) | Tall. |
| Eu/Mod ROM | .zip | No. | Tall. |
What if the “Select File” button does not appear?
Firmware via Fastboot and computer
Using Fastboot is the “heavy artillery” of Xiaomi’s firmware world, a method that is needed to restore the system after major failures, roll back versions (Downgrade), or completely delete all data, USB-Cable and utility Xiaomi Flash Tool.
First, you need to unlock the bootloader, which requires you to submit an application through the MI Unlock application and wait from 7 to 168 hours. Without the unlocked bootloader, you can not install Fastboot firmware. Once you get permission, download the.tgz archive, unpack it and launch the utility.

⚠️ Note: Fastboot’s firmware process completely erases the device’s internal memory. Make sure all important photos and contacts are saved in the cloud or on PC.
During the process, do not turn off the cable or touch the device. The utility will show the transaction log, and the successful completion will be marked in green with the words "Success". If there is an error, check the drivers. ADB quality USB-port.
💡
Fastboot is the only way to roll back on an older version of Android or MIUI if the current one is unstable.
Common mistakes and ways to solve them
Even with strict adherence to the instructions, there can be unforeseen situations, and one of the most common problems is the “Can’t verify update” error, which often happens if you try to install an older version on top of a new one without being completely cleaned, or if the firmware file is damaged when you download it.
Another common problem is a “bootloop” (cyclical reboot), when the phone gets stuck on the Redmi or Xiaomi logo. In most cases, it helps to enter Recovery mode (press the power and volume + button) and select the “Wipe Data” item. If this does not help, you will need to flash it through the Fastboot.
- 🔋 Battery Settled: If the device is turned off during installation, plug in the original charger and leave for 30 minutes, then try turning on.
- 📉 Lack of space: Remove app cache or large video files before starting an update.
- 🌐 Network error: Change DNS 8.8.8.8 in Wi-Fi settings or use a mobile access point.
Sometimes after the update, you may experience problems with autonomy, which is normal for the first 2-3 days, while the HyperOS system re-indexes files and optimizes the operation of applications.
💡
If the phone starts to run out quickly after the upgrade, go to the battery settings and check if any app has been listed as an Energy Eater, often by cleaning the cache of a problematic app.
