Owners of Xiaomi smartphones often encounter a situation where the system notifies about the release of a new version of the shell MIUI or HyperOS, but downloading is impossible due to a lack of a stable internet connection. This is a common issue, especially in situations with unstable mobile data or when using limited corporate networks. The standard over-the-air update mechanism requires a significant amount of data, which isn't always available through the operator's mobile network.
Fortunately, the company's engineers have provided alternative update installation methods that bypass the need for a direct connection to a wireless access point. You can use a personal computer as a source for firmware files or use another smartphone as a modem. These methods not only solve the Wi-Fi problem but also often help fix errors that occur during standard installation.
In this guide, we'll cover all the available options, from simple settings to manual file selection. Proper preparation It's critical to reset your device before starting the procedure to avoid data loss or software failures. Following the instructions will allow you to access the latest features and security patches while bypassing network restrictions.
Preparing your device and backing up your data
Before performing any manipulations with system software, you must secure your personal data. Even if you use a gentle update method, the risk of accidental failure always exists. Backup — This is a mandatory step that cannot be ignored, especially if you have important contacts and photos stored on your device.
You can create a backup using Xiaomi's built-in cloud or local storage. To do this, go to the section Settings → About phone → Backup and restoreSelect the items you want to save and start the process. Make sure the copy is saved either to the cloud or transferred to an external drive.
⚠️ Note: If you plan to upgrade between different Android versions (for example, from Android 13 to 14), your data may be deleted automatically. Always check the update type before installing it.
It's also important to check your battery level. The flashing process, even without rebooting into recovery mode, consumes power. If the device turns off during the critical moment when system files are being written, this could lead to software failureCharge your smartphone to at least 60-70% before starting work.
Method 1: Using a PC and USB Cable
The most reliable way to update Xiaomi Without Wi-Fi, you download the full firmware package to your computer and then install it via USB. This method is ideal if you don't have unlimited data on your phone but have internet access via a PC. You'll need to find the official firmware version for your specific model.
Firmware files have the extension .zip and weigh between 3 and 5 gigabytes. They should only be downloaded from trusted sources, such as the official website. MIUI Downloader or authorized forums. After downloading, do not unzip the archive or modify its structure—the system should view it as a single, coherent unit.
☑️ Pre-installation check
Transfer the downloaded file to your smartphone's internal storage, into the root directory (not into folders). Then go to the update menu and select "Manual File Selection." The system will verify the data integrity and, if everything is correct, prompt you to begin the installation. This method often resolves issues where updates get stuck at 0% or 100% when downloading over the network.
Why is the computer method more reliable?
Using a PC eliminates the risk of download interruptions due to an unstable mobile network signal. Furthermore, it's easier to verify the file's checksum on a computer to ensure its integrity before transferring it to your smartphone.
Method two: Sharing the Internet from another device
If you don't have a computer handy but have a second smartphone with an unlimited data plan or Wi-Fi connection, you can use it as a modem. Enable Hotspot mode on the second device and connect your Xiaomi to the created network. To the system, it will appear as a regular Wi-Fi connection.
Once connected, run the update check from the standard menu. Mobile hotspot Often bypasses restrictions that carriers may impose on system updates via standard mobile data. Download speed will depend on the signal quality of the receiving device.
In some cases, carriers block ports or traffic types specific to system updates. If standard tethering doesn't help, try changing the access point name (SSID) on the second phone, adding the word "update" to the name, or changing the language to English. This can sometimes help reroute traffic through less congested carrier gateways.
Manual file selection and Recovery mode
There's a hidden method for activating manual file selection if the "Select File" button isn't visible in the menu. To do this, quickly tap the MIUI version icon in the upper-right corner of the update screen several times. Once the "Additional Features" pop-up appears, the file selection button will become available.
If the system refuses to accept the file through the standard menu, you can use the mode RecoveryTurn off your smartphone and press and hold the power and volume up buttons. In the menu that appears, select your language and click "Connect with MIAssistant" (if available) or simply select the firmware file if the interface allows.
However, the safest way through Recovery is to use the "Select service pack" feature in the main Recovery menu. Go to Recovery Mode → Connect with MIAssistant (requires a PC) or select "Choose update package" directly in the recovery menu if the file is already in memory.
| Method | Saving data | A PC is required | Complexity |
|---|---|---|---|
| Via USB (MIUI) | Yes | Yes (for download) | Low |
| Hotspot (Access Point) | Yes | No | Low |
| Recovery Mode | Depends on the type | No | Average |
| Fastboot (ADB) | No (full reset) | Yes | High |
Troubleshooting common installation errors
Users often encounter the message "Failed to verify file" or "File is corrupted." This means that the checksum of the downloaded archive does not match what the system expects. File integrity This is broken if the file was downloaded incorrectly or was renamed. Make sure the file name doesn't contain any extra characters.
Another common issue is regional version incompatibility. You can't install a global firmware over a Chinese (CN) or European (EEA) firmware without unlocking the bootloader. The system will block the installation because the digital signature differs for each region.
⚠️ Warning: Attempting to change the region without an unlocked bootloader will result in a verification error. Changing the region (for example, from China to Global) requires complex procedures that involve completely erasing your data.
If the update gets stuck at the verification stage, try clearing the cache of the Update app. Go to Settings → Apps → All apps → Software update and tap "Clear Cache." Afterwards, restart your device and try selecting the file again.
Frequently Asked Questions (FAQ)
Is it possible to update Xiaomi via 4G mobile internet?
Technically, this is possible, but highly discouraged due to the large amount of traffic (3-5 GB) and the risk of connection interruption. Carriers may block such requests or charge them as regular traffic, resulting in significant costs.
What should I do if my phone turns off during the update?
If your device won't turn on, try entering Recovery mode (Volume Up + Power). If the menu opens, try reinstalling the firmware. If the phone doesn't respond at all, you'll need to reflash it using Fastboot on a PC.
How long does it take to install an update via USB?
The installation process itself takes 5 to 15 minutes. However, preparation (searching, downloading to your PC, and transferring the file) may take longer depending on the speed of your internet connection.
Do I need to unlock the bootloader for a regular update?
No. Unlocking the bootloader is not required to install official updates (even manually selected ones). It is only necessary when changing the firmware region or installing custom builds.
