How to update Xiaomi Redmi Note 7: current methods

The Xiaomi Redmi Note 7, released in 2019, is still a popular device due to its price-performance balance.However, over time, the software needs to be updated to ensure data security and compatibility with new applications. Users often look for ways to update the Xiaomi Redmi Note 7 to extend the life of the gadget and get new features of the MIUI shell.

The process of installing a new firmware version can range from simple booting over Wi-Fi to more complex computer manipulations. In this guide, we will examine all available methods, from standard air updates to manually installing archives through the Recovery menu. It is important to understand that system upgrades are critical operations that require attention and preparation.

Before you start, make sure your device really needs an update. Sometimes automatic notifications don't come due to regional features or the status of the software version. We'll look at how to check the system's relevance and where to find official firmware files if the automatic search didn't work.

Preparation of the device for installation of updates

Any interference with the software part of the smartphone requires prior preparation. Ignoring this stage can lead to data loss or malfunction of the Redmi Note 7. The first thing you need to do is back up important contacts, photos and documents. Xiaomi's built-in tools allow you to do this quickly and conveniently.

Be sure to charge the battery of the device. The charge level should be at least 60%, and ideally 80%. The process of writing data to the internal drive consumes energy, and suddenly turning off the smartphone during firmware can lead to serious errors that require flashing through the Fastboot.

⚠️ Warning: Do not interrupt the upgrade process even if the screen is gone or the phone appears to be getting stuck.A forced reboot at this point can turn the device into a brick».

Also check for free storage space. You may need 3 to 5GB of free space to download and unpack the update archive, and if the memory is full, the system will not be able to complete the installation correctly.

Method 1: Automatic Network Update (OTA)

The easiest and safest method for the average user is to update through the built-in OTA (Over-The-Air) mechanism.The system itself checks Xiaomi servers for new versions of the MIUI shell or Android security patches.

To start the check, go to the settings menu and select About Phone, which displays the current firmware version and build number. Click on the MIUI version icon or the Check Updates button. If the new version is available, a window will appear describing the changes and a download button.

Once you download the archive, the system will suggest restarting, shutting down the phone, installing files, and turning on again with the new version of the software, which ensures that you get a formal, proven build that is optimized for your model.

💡

Use a stable Wi-Fi connection to download OTA-Updates as files can weigh more than 2GB, which will quickly consume mobile traffic.

But sometimes it doesn't happen, and it could be because you're using a global firmware version and the update came out first for China, or it could be because the servers are being updated in stages, and you're going to have to wait a few days or use a manual method.

Method 2: Manual installation via Recovery menu

If the automatic search doesn't find updates, you can download the firmware file manually, a technique known as "local update" that allows you to install a specific version of MIUI without queuing servers, and you'll need a file with the.zip extension specifically designed for the Redmi Note 7 (codenamed lavender).

Download the current firmware from the official website or a trusted resource. Importantly, choose the version of Recovery rather than Fastboot (it usually has the extension.tgz or.zip, but the name should indicate Recovery). Place the downloaded file in the root of internal memory or on the memory card, so it is easy to find.

Then open the Explorer app or go to the update settings. In some versions of MIUI, you need to click several times on the version icon to activate the optional menu. Select "Select firmware file" and specify the path to the downloaded archive. The system will check the integrity of the file and prompt you to start installing.

⚠️ Warning: Make sure the downloaded firmware version is newer than the one installed now.Attempting to roll back to an older version via Recovery without unlocking the bootloader will lead to an error.

This is a good way to do this, because it doesn't require a computer connection or a driver, and it's all done directly on the screen, and the key is to make sure you're not wrong with the model, because the firmware from Redmi Note 7 Pro is not suitable for the regular Note 7.

Use of Mi Flash Tool and Fastboot Mode

For advanced users who have experienced serious system errors or want to completely clean the device, Fastboot is a method of firmware, which requires a Windows computer and a USB cable, and allows you to install a clean version of the system, ignoring the state of the current software.

Before starting the procedure, you must unlock the bootloader through Mi Unlock. Without this step, the Mi Flash Tool will refuse to write data to the phone's memory. The unlocking process can take from 3 to 7 days after submitting an application in the Mi Account.

Download and install the ADB and Fastboot drivers, as well as the Mi Flash utility itself. Download the firmware archive in.tgz and unpack it to the root of the C disk so that the path does not contain Cyrillic. Launch the program, plug the phone off by pressing the volume button, and press Refresh.

In the program interface, select the path to the unpacked firmware folder. In the bottom corner, select Clear All mode to avoid compatibility errors. Press Flash and wait for the process to be completed, which will take about 200-300 seconds.

💡

Fastboot is the only way to restore the phone if it has stopped booting into the system but requires an unlocked bootloader.

Common mistakes and ways to solve them

During the upgrade process, users of the Xiaomi Redmi Note 7 may encounter various problems. One of the common mistakes is the message “failed to check the update”, which is often associated with an unstable Internet connection or a crowded update service cache.

To solve the problem, try clearing the Update app cache. Go to the settings, select Apps, find Software Update, and click Clear Data. Then try again to check. DNS-servers in Wi-Fi settings at 8.8.8.8.

Another common situation is a bootloop after installation. If the phone is stuck on the Mi or Android logo for more than 15 minutes, try entering Recovery mode and selecting "Wipe Data" to delete all data, but can save the system.

If nothing helps and the phone doesn't respond to the buttons, the system partition may be damaged, in which case only flashing through the Fastboot with full cleaning, as described in the previous section, will help. Don't be afraid to contact the service if you are afraid to perform complex ones yourself.
