How to update the phone Xiaomi Mi 8 Lite: all the ways

Modern smartphones require regular software maintenance to ensure stable operation and security. Xiaomi Mi 8 Lite, released in 2018, is still a popular device, but its relevance depends on the version of the operating system installed. Users often face a situation where automatic notifications about updates stop coming, although new versions of MIUI are already available.

The upgrade process doesn’t always go smoothly due to differences in firmware regions or server failures. Device owners need to know alternative installation methods if the standard settings path doesn’t work. In this article, we’ll detail how to safely upgrade the Xiaomi Mi 8 Lite to the latest available version of MIUI 12 based on Android 10, using official tools and proven techniques.

Ignoring updates can lead to lower application performance and security vulnerabilities. In addition, newer versions of the shell often contain optimizations that extend the life of the battery. Let's look at the basic methods of transitioning to fresh software, from the simplest to advanced techniques.

Preparation of the device for the update procedure

Before you start any manipulation of system files, you need to make sure that the device is fully ready for operation. Battery charge should be at least 60%, since the firmware process is energy intensive. It is also critical to create a full backup of all data, since when you switch between major versions of Android (for example, from 9 to 10), the files can be deleted.

Free up the internal memory of the device, leaving at least 3-4 GB of free space. Update files weigh a little, but the system requires space to unpack archives and temporary files. Check the stability of the Internet connection, it is desirable to use a Wi-Fi network with high data rates.

⚠️ Warning: Do not interrupt the installation process even if the screen is gone or the phone appears to be getting stuck.A forced reboot at this stage may cause the bootloader to crash.

Make sure you use the original cable and power supply if you plan to keep your phone charging during the process. download all the necessary files in advance so as not to depend on the internet speed at the time of installation.

Automatic update via settings (OTA)

The easiest and safest way to get a new version of the software is to use the built-in OTA (Over-The-Air) mechanism. The system itself checks the servers for current packets and suggests downloading them. To do this, go to the Settings menu → About the phone and click on the icon version of MIUI.

If you find an update, the phone will suggest you download it and restart it for installation. However, the servers are updated in stages, so your device may receive an update later than other users, sometimes changing the region in the settings helps, but this does not guarantee the result.

In some cases, automatic search may not work because of the update app cache. Try clearing the Component Update system application data through the application management menu. This often solves the problem of a stalled search for a new version.

💡

If the “Check Updates” button does not respond, try switching the system language to English, checking for an update, and then returning the Russian language.

The advantage of OTA is that it's a low risk of data loss and easy execution, so you don't need any extra files or a computer, the whole process is controlled by the operating system, and it's ideal for inexperienced users.

Manual installation via Recovery (Method with ZIP-archive)

If OTA does not work, you can update manually by downloading the installation package from the official website. You will need a firmware file in.zip format, which corresponds to your model (platina is codenamed Mi 8 Lite) and the firmware type (Global or China).

Copy the downloaded archive to the root of the phone's internal memory. Don't put the file in folders, it should be separate from other data. Next, 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 the version is suitable, prompt you to start installing it. Once confirmed, the phone will reboot to Recovery mode, where the flashing process will take 5 to 15 minutes, depending on the amount of changes.

⚠️ Note: You can't downgrade the Android version with this method.Attempting to roll back from Android 10 to Android 9 via Recovery will result in an error and a possible bootloop (cyclical reboot).

Use Fastboot Mode and Mi Flash Tool

For advanced users or in cases where the phone does not load normally, the method of firmware through Fastboot is suitable. This method requires a Windows computer and a driver installed. ADB/Fastboot, It also cleans up the memory of the device, as well as the Mi Flash Tool.

Download the firmware image in.tgz (not zip!) and unpack it to the root of the C disk so that the path is Cyrillic-free and short. Put the phone in Fastboot mode, holding both the Volume Down button and Power before the hare appears in the hat.

Connect the device to your PC and start the Mi Flash Tool. Choose the path to the unpacked firmware folder and click the "Flash" button. In the lower right corner, select the "Clean all" mode for clean installation. The process will take a few minutes, after which the phone will automatically restart.

Possible mistakes and ways to solve them

Update can cause a variety of problems, from a simple lack of space to signature verification errors, a common problem is the message “Can’t verify update”, which occurs when you try to install global firmware on the Chinese version of the device or vice versa, in which case only a complete flashing through the Fastboot helps.

If the phone is stuck on the Mi logo after the upgrade, try resetting to factory settings via Recovery Mode. To enter it, press Volume Up and Power. Select Wipe Data, confirm the action and wait for the cleanup.

Sometimes the update is successful, but the applications start to work incorrectly, in which case it is recommended to clear the cache of all applications or perform a full reset. Problems with heating in the first days after the update are normal, since the system conducts file indexing.

⚠️ Warning: If the proximity sensor or screen stops working after the update, don't rush to bring the phone to the service. Often calibration through the engineering menu or reflashing in the original way helps.

Should I install custom firmware?

Official support for Xiaomi Mi 8 Lite ended with Android 10, but enthusiasts continue to release custom builds based on Android 11, 12 and later. Installing such firmware (LineageOS, Pixel Experience) allows you to get a fresh interface and features that are not available in stock MIUI.

Custom firmware requires unlocking the bootloader through the official Mi Unlock utility, which will result in warranty and data deletion.The process requires deep knowledge, as an error can turn a smartphone into a brick.In addition, the camera or NFC can malfunction in custom builds.

If you want to make sure that you're doing this, consider the risks. If you want to keep your calls and banking apps stable, you'd better stay with the latest official version of MIUI. Custom firmware is the lot of experimenters who are willing to put up with bugs for novelty.

💡

Official support for the Mi 8 Lite is now complete, so manually installing the latest stable MIUI 12 is the best way to extend the life of the device without risk.

In conclusion, regular software updates are key to keeping your smartphone safe and fast. Choose a method that matches your skills and always back up before you start work. The right approach will keep your Mi 8 Lite up to date for a long time to come.
