Modern Xiaomi and Redmi smartphones require regular software maintenance to ensure maximum performance and data security. Many users delay this process for fear of losing important files or facing system errors, which is a common misconception. In fact, the procedure for updating MIUI or the new HyperOS shell is as automated as possible by developers and takes only a few minutes of your time.
In this article, we will discuss in detail all available methods for installing new firmware versions, from a standard “over the air” update to manual installation through a computer. You will learn how to properly prepare the device, what to do if the update button is inactive, and how to avoid common errors that can lead to data loss or “bricking” of the gadget.
Regular security patches are critical to protecting your personal data from today’s threats to the network, and newer versions of the operating system often include battery optimization and camera performance improvements that significantly extend the life of the device.
Preparing the smartphone for installing updates
Before you start the process of downloading and installing new files, you need to perform a number of preparatory steps, which ensures that interruption of the process due to battery discharge or memory shortage will not lead to critical failures in the work of Bootloader or system partitions.
First, make sure that the battery is at least 60%, and ideally connect the device to the power source, and also check for free space in internal memory, as the installation package can take from 3 to 5 GB depending on the version.
⚠️ Before you start any manipulation of system files, be sure to back up all important data in the Mi Cloud cloud service or on your computer to avoid their irretrievable loss.
A stable connection to the Internet is another key requirement, especially for downloading heavy service packs, and using Wi-Fi is preferable to mobile traffic, as it will provide high speeds and eliminate connection breaks at a critical moment.
☑️ Readiness for renewal
Automatic update via settings (OTA)
The easiest and safest way to get a new version of the software is to use the built-in OTA (Over-The-Air) mechanism, which does not require a connection to a computer or special knowledge, since the system itself checks for the availability of current packages on the manufacturer's servers.
To start the process, go to Settings → About the phone and tap the logo of the MIUI or HyperOS version. The system will contact the server and, if a new build is already released for your Redmi model, will offer to download and install it.
Sometimes users are faced with a situation where the notification comes but the download does not begin, in which case clear the cache of the System Update app through the app menu or simply wait a few hours until the servers unload.
- 📱 Go to Settings. → About the status check phone.
- 📡 Make sure that mobile internet or Wi-Fi is enabled.
- 🔄 Click Download and Install if the button is active.
- ⏳ Wait for the installation to be completed and automatic restart.
Manual installation of firmware through Recovery
If you don’t get an automatic update or want to install a specific firmware version (e.g., switch from China to Global), you can use the manual installation method via Recovery mode, which requires you to download the firmware archive from the official website or verified resources.
The downloaded file must have a.zip extension and be at the root of the internal memory or on the SD-After downloading the file, go to the update menu, click three dots in the corner of the screen and select "Select firmware file».
⚠️ Note: When manually installed, make sure the firmware region matches the region of your device, otherwise activation errors or blocking functions may occur.
The system will check the integrity of the file and, if all parameters are correct, prompt a reboot to start the installation, a method often used to "cure" software errors when a standard update does not help fix bugs.
What to do if the file is not selected?
Update via computer with the Mi Flash Tool
For advanced users who need a clean system installation without saving user data, the Mi Flash Tool is designed.This method allows you to reflash the device in Fastboot mode, which is especially important in case of serious system failures or transition between global regions.
You'll need to download the firmware archive in.tgz, unpack it, and install the ADB and Fastboot drivers on your computer. Once you put your smartphone into fast boot mode (clamping the volume button when you connect the cable), you can start the firmware process.
fastboot devicesThis command in the command line will help make sure your computer sees your Redmi device. If the device appears in the list, you can run a firmware script or use the Mi Flash graphical interface to select Clean All data cleanup mode.
- 💻 Download and install drivers ADB/Fastboot PC-only.
- 📂 Unpack the firmware archive in the root of the C disk: for a short path.
- 🔌 Transfer the phone to Fastboot mode (volume button down) + feeding).
- 🚀 Run the Mi Flash Tool and select the firmware file.
Comparison of System Update Methods
The choice of upgrade method depends on your goals, technical training and current state of the device. Below is a comparison table that will help determine the best way to install a new version of Android or shell.
| Method | Difficulty | Data retention | The need for a PC |
|---|---|---|---|
| OTA (Airway) | Low. | Yes. | No. |
| Manual (Recovery) | Medium | Yes. | No. |
| Mi Flash (Fastboot) | Tall. | No (usually) | Yes. |
| EDL Mode | Expert | No. | Yes. |
For most users, the best option is to upgrade through settings or Recovery, as these methods are the least risky. Using Fastboot is justified only in cases where you need a complete system reset or recovery from a failed modification.
💡
Use the Mi Flash method only if you are confident in your actions, as a mistake in choosing a region or interrupting the process may lead to the need for maintenance repairs.
Solving errors during the update
During the upgrade process, Xiaomi and Redmi users may encounter various errors, such as “failed to check the update” or an endless reboot cycle, often with an unstable Internet connection or a crowded cache of system services.
If you see a check error message, try changing it. DNS-servers in Wi-Fi settings on 8.8.8.8 or use a mobile network. Also an effective way is to clean the system update application data through the application management menu.
⚠️ Note: If after the update the phone stopped turning on or is extremely slow, reset to factory settings (Wipe Data) through the Recovery menu, previously saving data.
In some cases, the new firmware version may not be compatible with the installed modifications or root rights.Be sure to remove all system changes before upgrading the modified devices and return the stock bootloader.
- 📉 Checking error: change the network or DNS.
- 🗑️ Small space: remove unnecessary photos and videos.
- 🔋 Battery Discharge: Connect the Original Charger.
- 🔒 Blocking: Make sure your Mi Account is unlocked.
💡
If the update is stuck at 99%, don't panic or turn off the phone right away.Wait 15-20 minutes as the system can complete the application's background optimization.
