The Xiaomi Redmi Note 7, which was released in early 2019, has been a hit and still hits millions of users. However, over time, the Android operating system and the MIUI shell cease to receive automatic notifications about new versions, which may raise questions from device owners. The software update process is critical not only to get new features, but also to install security patches that close system vulnerabilities.
Many users are faced with a situation when the phone stops offering new versions of firmware through the standard menu, although officially support for the model is not yet over or a more stable build is available. In this article, we will discuss in detail how to update the software of your gadget, what risks exist and how to prepare for the procedure so as not to lose personal data.
There are several ways to install new versions of MIUI, from standard air updates to manually installing the archive through Recovery, depending on the current version of the system, the region of use of the device and the desired result. Below we will look at each step in as much detail as possible.
Preparation of the device for installation of a new version of the software
Before you start any manipulation of system files, you need to do thorough preparation. Ignoring this stage can lead to the loss of contacts, photos and other important data. Backup is the first thing you should do, even if you plan to simply upgrade the system without resetting.
Make sure that the battery is at least 60 percent, and ideally fully charged. The process of writing data to flash requires a stable voltage, and suddenly turning off the phone at this point can lead to serious boot errors.
- 📱 Backup your data via the Mi Cloud or locally to your computer.
- 🔋 Charge your smartphone to a minimum 60-70% before the beginning of the procedure.
- 💾 Free up space in internal memory (preferably more than 5GB).
- 📶 Connect to a stable Wi-Fi network to download files.
Also worth checking is the model of your device. Redmi Note 7 has several modifications (global, Chinese, Indian), and firmware for them is not always compatible. Installing the wrong region can lead to errors or block some functions.
☑️ Readiness for renewal
Automatic updates through system settings
The easiest and safest way to upgrade Android and MIUI shell is to use the built-in update mechanism, which checks the manufacturer’s servers for new builds that are suitable for your configuration.
To start, go to the settings menu and find About Phone, which displays the current MIUI version and Android build number, and click on the major MIUI logo icon or System Update to start the check.
⚠️ Note: If the system says "No updates found", it does not always mean that there are no updates.
In some cases, it is useful to change the region in the settings (Settings → Advanced Settings → Region), for example, to India or Global, and check again for updates, this can force the search for the current version of the software.
Manual installation of firmware through Recovery
If the automatic search failed, you can update manually, which requires you to download the installation file from the official site and its placement to the root of the phone’s internal memory, an approach that often allows you to upgrade to a newer version without going through the intermediate steps.
You will need to download the.zip (Recovery ROM) firmware archive that matches your model and region. After downloading, move the file to the root directory of internal memory without putting it in folders.
The algorithm of actions is as follows:
- 📂 Go to Settings. → The phone. → Updating the system.
- 👆 Click on the version icon several times MIUI, to activate the hidden menu.
- 📁 In the menu that appears, select Select a firmware file and specify the downloaded archive.
- 🔄 Confirm the action, the phone will restart and start installing.
It is important to understand that manually upgrading from an older version to a significantly new one (e.g. from MIUI 10 to MIUI 12) may require a complete data reset, and the system will alert you before installing.
What to do if the installation is interrupted?
Update via Fastboot and Mi Flash Tool
For advanced users who want to completely clean the system or restore the device after a crash, there is a method of firmware through the computer. This method uses the Fastboot mode and the Mi Flash Tool utility.
This method requires an unlocked bootloader for global firmware versions, although some older versions of the tools allowed flashing BL in Emergency Download (EDL) mode, which is now hampered by Xiaomi’s security policies.
The process is as follows:
- Download and install the ADB and Fastboot drivers, as well as the Mi Flash Tool program on your PC.
- Download the Fastboot ROM (.tgz archive) and unpack it to the root of the C drive.
- Turn off your phone and enter Fastboot mode by pressing the Volume Down + Power buttons.
- Connect the cable to the computer and run the firmware through the utility.
⚠️ Note: When choosing Clean all in the Mi Flash Tool, all data on your phone will be permanently deleted.
Using this method guarantees the installation of a clean system without debris from previous versions, but requires high concentration and accurate follow-up to instructions.
💡
Use the original. USB-cable and connect the phone directly to the motherboard port (back of the system unit), avoiding USB-hubs to avoid communication interruption during firmware.
Possible problems and ways to solve them
Updating can cause errors ranging from simple space shortages to system file conflicts, and understanding the nature of these issues can help you quickly resolve them without going to a service center.
A common problem is the “failure to update” or “file corrupted” error, which may mean that the downloaded archive does not match the current firmware version (you can’t roll back to older versions without resetting) or the file has been downloaded with errors.
| Type of error | Possible cause | Decision |
|---|---|---|
| Not enough space. | Little memory. | Delete photos, videos or apps |
| File damaged. | Download error or hash sum | Download the firmware from another source |
| Incompatibility | Attempted rollback version | You need a full reset (Wipe Data) |
| Server error | Problems with the Internet or MIUI server | Change your DNS or use a VPN |
If the phone is slow or crashes after the upgrade, it is recommended to perform a full reset to factory settings (Wipe Data/Factory Reset) via Recovery.This will delete all user data, but ensure the stable operation of the new system.
💡
A full reset after a major update to the Android or MIUI version often solves 90% of performance and autonomy issues.
