The smartphone Redmi Note 7, released by Xiaomi, remains a popular device even several years after its release. Users often wonder how to extend the life of a gadget and get new features through software updates. The main difficulty is that official Android support for this model has already been completed at the MIUI 12 shell level, but enthusiasts are looking for ways to install more recent versions.
The process of upgrading the system can vary from a simple check of available patches in the settings to complex manual flashing via a computer. The choice of method depends on your current software version, bootloader unlocking and the desired result. In this article, we will analyze in detail all the available ways to update the software for your device.
Before taking any action, it is critical to understand the risks. Incorrect installation of the firmware can lead to data loss or turning the smartphone into a “brick”. Always make a backup copy of important contacts and photos before starting any manipulations with the system.
Checking for available updates through the settings
The safest and easiest way to upgrade your Redmi Note 7 is to use the built-in OTA (Over-The-Air) mechanism. Xiaomi regularly releases security patches and minor improvements, even for older models if they are still in the support cycle.
First, make sure that your device is connected to a stable Wi-Fi network. mobile data may be unstable when downloading large amounts of data, which will lead to file verification failure. The battery charge must be at least 60% so that the phone does not turn off at a critical moment.
Go to the menu Settings and find the item About phone. The current MIUI version and Android build number are displayed here. Click on the large icon with the system logo or the Check for updatesbutton. The system will contact the server and report the availability of a new version.
If an update is found, a window will appear describing the changes (Changelog). Please read it carefully to understand exactly what will change in the operation of the device. Often the list includes fixes for security vulnerabilities or optimization of camera performance.
⚠️ Attention: If the check for updates button is not active or gives a network error, try changing the DNS server in the Wi-Fi settings to 8.8.8.8. Sometimes local providers block the connection to Xiaomi update servers.
Before clicking the “Update” button, close all running applications. Background processes can consume RAM and slow down the installation process, causing a timeout.
Manual installation of firmware via Recovery
When the automatic update does not arrive or you want to install a specific version of MIUI that is not available in OTA, the manual installation method of Recovery ROM is used. This method does not require unlocking the bootloader if you are installing official global or Chinese firmware on top of a similar version.
You will need to download the archive with the firmware in the format .zip. It is important to select a file specifically for the model M1810F6L (code Redmi Note 7). Incorrectly selected firmware from another model (for example, Note 7 Pro) can damage partitions of the device.
After downloading the file, move it to the root directory of the smartphone’s internal memory. Do not put the archive in folders with Russian names or deep nesting, as the built-in bootloader may not see the path to the file.
Next, go to the menu again About phone and quickly click 10 times on the icon of the current MIUI version. The message “Additional update features are enabled” appears. Click on the three dots in the upper corner of the screen and select Select firmware file.
- 📂 Make sure that the downloaded file has the extension
.zipand is not unpacked by an archiver. - 🔋 Charge the battery to at least 70% before starting the installation process.
- 💾 Free up at least 5-6 GB of free space in the internal memory for temporary files.
☑️ Preparing for manual firmware
Updating via Fastboot mode and computer
The method of flashing firmware via Fastboot is the most powerful tool in the Xiaomi user's arsenal. It allows you not only to update the system, but also to completely clear the device of errors accumulated over years of use. For this method unlocking the bootloader is required.
You will need a computer running Windows, an original USB cable and the Mi Flash Tool utility. Download the firmware image in the format .tgz (Fastboot ROM) and unpack it to drive C so that the path does not contain Cyrillic characters.
Transfer the smartphone to Fastboot mode by simultaneously pressing the Volume Down and Power buttons until the Mi hare logo appears Bunny. Connect your phone to your PC. A device with the name Android Bootloader Interface.
Run Mi Flash Tool as administrator should appear in Windows Device Manager. Press the Refreshbutton for the app to see your smartphone. At the bottom of the window, select the firmware mode: Clean all (full cleaning) or Clean all and lock (cleaning and locking the bootloader).

What is the difference between the firmware modes?
The "Clean all" mode deletes all user data, but leaves the bootloader unlocked. The "Clean all and lock" mode returns the device to its factory state with a locked bootloader, which is necessary for banking applications and Google Pay to work, but makes it impossible to install custom recoveries in the future without re-unlocking.
Switching to custom firmware and new Android
Official support Redmi Note 7 ends on Android 10 with MIUI 12 skin. If you want to get Android 11, 12 or even 13, the only option is to install custom ROMs such as LineageOS, Pixel Experience or Evolution X.
This process requires advanced skills. First, you need to unlock the bootloader through the official Mi Unlock utility after waiting for the mandatory waiting period (usually 7 days). Then a custom recovery is installed, for example, TWRP, through which the new system is already packaged.
Custom firmware often works faster than the official ones, since they are devoid of heavy MIUI code and pre-installed garbage. However, you lose the warranty (if you still have one) and the stability of some functions, for example, the camera or VoLTE, which may not work correctly.
| Firmware type | Installation complexity | Stability | Android version |
|---|---|---|---|
| Official OTA | Low | High | Up to Android 10 |
| Recovery ROM | Medium | High | Up to Android 10 |
| Fastboot ROM | High | High | Up to Android 10 |
| Custom (AOSP) | Very high | Average | Android 11-14 |
Installing custom firmware is the only legal way to get the latest Android on Redmi Note 7, but this requires unlocking the bootloader and resetting all data.
Possible errors and solutions
During the update process, users often encounter the error “Not managed to check the update" or stuck on the Mi logo. Most often, the problem lies in a damaged firmware file or incompatibility of regions.
If the phone is stuck in an endless reboot (bootloop), try entering Recovery mode (Volume Up + Power) and reset to factory settings (Wipe Data). This will delete all data, but can restore system functionality.
If signature verification fails in Recovery mode, make sure that you do not try to install Chinese firmware on the Global version of the device without first unlocking the bootloader and completely clearing the memory. Signatures of different regions are not compatible with each other.
⚠️ Attention: Menu interfaces and item names may vary slightly depending on the version of MIUI. If you do not find the item you need, use the settings search or check the current screenshots for your shell version.
