Xiaomi’s current Redmi Note series is known for its ability to keep software up to date. Regularly getting new versions of Android and its proprietary MIUI (or HyperOS) shell not only adds new features, but also closes security vulnerabilities. Users often wonder how to initiate this process to avoid losing data and avoiding errors.
The upgrade procedure can be done in several ways: standard through the settings menu, manually through the download of a firmware file or using a computer. The choice of method depends on the current version of the system, the region of the device and the desired speed of receiving updates. It is important to understand that the transition between the global and Chinese versions of the firmware requires unlocking the bootloader. In this article, we will discuss in detail all the nuances of the transition to fresh Android.
Before you start to take action, you need to make sure that the Internet connection is stable and battery power is charged. Interrupting the download or installation can lead to serious malfunctions in the gadget. Let's consider the preparatory stage, which will be the foundation for the successful installation of the new system.
Preparing the device for system update
Any interference with system files requires preparation. The first step is to create a full backup of the data. Although a regular update does not usually affect the user's personal files, the risk of a software error is always there. You can use the built-in Security app or Google cloud services to save contacts, photos and settings.
The second critical aspect is to ensure that the battery is sufficiently charged: the installation of the new version of MIUI can take 10 to 40 minutes, during which the device should not shut down. If the battery runs out at the time of flashing the system partition, the smartphone can turn into a brick.
It is also recommended to free up space in internal memory. Update files can take from 2 to 5 GB, and the system requires additional space to unpack archives and temporary files. Check available storage can be found in the Settings menu → About Phone → Memory.
⚠️ Warning: Do not try to update a device connected to an unstable Wi-Fi network with permanent connection breaks. 4G/5G It is only permissible if there is an unlimited tariff, since the weight of the update packages is high.
☑️ Checklist of smartphone preparation
Automatic update via settings (OTA)
The easiest and safest method for most users is an over-the-air update (OTA), which checks for a new version of Android and suggests installing it, ideal for those who don’t want to know the technical details and prefer the standard way from the manufacturer.
To start the check, you need to go to the Settings menu → About the phone and click on the logo version MIUI. If the update is available, a Download button will appear. In some cases, the system may offer a choice between stable and beta.
Once you download a file that's a few gigabytes in size, the device will request a reboot for installation, and the screen will go out, and the Redmi logo will appear with a progress indicator, at which point you absolutely can't interrupt the process or extract it. SIM-map.
- 📲 Go to the Settings menu item.
- 🔄 Select About Phone and click on the system version.
- ⬇️ Press the Download button and wait for the process to end.
- 🚀 Confirm the installation and wait for the restart to complete.
💡
If the update doesn’t come in for a long time, try changing the region in settings (Settings → Additional settings → Region) to Indonesia or India, then return your region.
Manual installation of firmware through Recovery
If the automatic method doesn’t work or you want to upgrade to a specific version that OTA doesn’t offer yet, you can use the manual installation method. This requires downloading the.zip firmware file from the official website or proven resources.
Once you download the file, place it at the root of the device's internal memory. Don't put the archive in folders, use the main storage space. Then go to the update menu, click on the three dots in the upper right corner, and select "Select firmware file."
The system will check the integrity of the file and, if correct, prompt the installation to begin, a method that often helps push through an update when servers can’t see your device, or jump between regions of a single version (e.g., Global to EEA), although the latter may require data clearing.
| Parameter | Value for manual installation | Requirements |
|---|---|---|
| File type | Recovery ROM (.zip) | Not suitable Fastboot (.tgz) |
| Location. | The root of internal memory | No nested folders. |
| Battery charge | More than 60% | Network connection is recommended |
| Action | Selecting a file through the menu | Three dots in the corner of the screen |
What if the system says "file cannot be installed"?
Update via computer and Mi Flash Tool
For advanced users who have experienced serious errors or want to completely reassemble the system, there is a method of firmware through the PC. It requires the use of the Mi Flash Tool utility and drivers. ADB/Fastboot. This method allows you to restore the device even in the event of software failures, but carries risks.
Before you start, you need to unlock the bootloader through the official Mi Unlock app on your computer. This process can take from 3 to 7 days of waiting after submitting an application in your Xiaomi account. Without an unlocked bootloader, installing via Fastboot is impossible.
Once authorized, turn your smartphone into Fastboot mode, holding both the power and volume buttons when the device is turned off. Connect your phone to your computer with a USB 3.0 cable, launch Mi Flash, select the folder with the unpacked firmware and press the Flash button.
- 💻 Download and install drivers ADB Mi Flash Tool and the Mi Flash Tool.
- 🔓 Unlock the bootloader through the Mi Unlock site and wait for permission.
- 🔌 Transfer the phone to Fastboot mode (clamping Volume - and Power).
- ⚡ Run the firmware and select Clean All mode for clean installation.
⚠️ Note: When selecting the "Clean all" mode in the Mi Flash Tool, all data on the device will be permanently deleted.
Possible errors and methods of their solution
Redmi Note users may encounter various problems during the update process, one of the most common being the “Failed Update Information” error, which is often associated with server congestion or unstable servers. DNS. The solution lies in the shift. DNS-server in Wi-Fi settings on 8.8.8.8 or using a mobile network.
Another common problem is getting stuck on the MI logo after installation. If the device is hanging on the screensaver for more than 15 minutes, try to perform a forced reboot by holding the power button for 10-15 seconds. If this does not help, you may need to log in to Recovery mode and a Wipe Data reset, which confirms the need for a backup.
Also worth mentioning is the problem of app incompatibility: After a major Android update, some old apps may not work properly, in which case cleaning the cache of a particular application or reinstalling it from Google Play will help.
If you upgrade to a new version of MIUI and notice a fast battery drain, give the device 2-3 days. The system performs file indexing and optimization of background processes, which temporarily increases power consumption.

Most update errors are not related to the firmware file itself, but to an unstable internet connection or a device’s overflowing memory during installation.
