How to update the Android system on the phone Xiaomi Redmi 8

Owning a Xiaomi Redmi 8 is a great experience with a budget device that has been around for years with regular updates. However, over time, users begin to notice that standard notifications about the new version of the system stop coming, and the question arises about how to force the installation of a fresh Android. The software update process is critical not only to get new features, but also to close security vulnerabilities that are found in older versions of the MIUI shell.

Many owners mistakenly believe that if the automatic mechanism did not work, the device is no longer supported by the manufacturer. In fact, Xiaomi often leaves the current firmware packages on its servers, allowing users to manually activate the transition process to a newer version. In this article, we will discuss in detail all available methods, from simple settings in the menu to the use of special engineering modes that allow you to bypass the standard restrictions of regional versions.

Before you start any manipulation of system files, you need to clearly understand which version of the operating system you have installed now and which is the last available for your model. Redmi 8, released on the basis of Android 9, officially received an update to Android 10 with the shell MIUI 12, and this is the final milestone for this device. Attempts to install newer versions of Android through custom firmware go beyond official support and require deep knowledge, so we will focus on standard methods to ensure the stable operation of the gadget.

Check the current version and available updates

The first step in the software upgrade process is to thoroughly diagnose the current state of the system, so you need to log in to the settings menu and find the About Phone section, which displays all the technical information about the device, and that's where you'll see the MIUI build number and the Android version, which is the starting point for further action, and if the system offers an update right after checking, it's the easiest and safest way to do this.

However, it is often the case that the phone writes “No Updates found”, although the new version has already been released for your region, this is due to the fact that updates are spread in stages, and the servers may not send a signal to your particular device. In this case, it is useful to know that forced verification through the update menu sometimes helps to "wake up" the hidden data packet. MIUI several times to activate additional menu functions.

⚠️ Warning: Before starting any updates, be sure to back up important data, as in rare cases, a process failure can lead to loss of user information.

It’s also worth noting that connection stability plays a key role in successful service pack downloads. If you’re using mobile internet, the system can block large files over 100MB from downloading, requiring you to switch to Wi-Fi. Make sure your router is stable and the connection speed is sufficient to download gigabyte firmware files without cliffs.

Preparation of the device for the installation of new firmware

The quality of the device is the key to the successful completion of the upgrade procedure without the occurrence of critical errors. The first and most important condition is the battery charge: the charge level should be at least 60%, and ideally be fully charged to 1. In the process of writing data to the system partition, intense power consumption occurs, and a sudden power outage can damage the bootloader or “brick” the machine.

The second critical aspect is freeing up space in internal memory. Even if the service pack itself weighs 2-3 GB, the system requires additional space to unpack archives and temporarily store system files. It is recommended to have at least 5-7 GB free by deleting old photos, videos or transferring them to an SD card or cloud storage.

It’s also worth checking the integrity of the device itself and the lack of system modifications. If your Redmi 8 has received a Root Rights or unlocked a bootloader, the standard update mechanism may fail or result in a cyclical reboot, in which cases you need to pre-return to the stock version or use special firmware methods through your computer.

Also, be sure to disable any third-party antivirus or optimization software that may block the system updater from accessing the network or file system. Android’s standard security features are sufficient for security during the process, and third-party intervention can cause false positives and interrupt the installation.

Automatic update via settings (OTA)

The most common and safest method of updating is to use the built-in OTA (Over-The-Air) mechanism. To activate it, go to Settings → About Phone → MIUI Version. On the screen that opens, click on the large icon of the MIUI logo. If the update is available, the system will start downloading it automatically. This method is preferred for most users, as it guarantees the compatibility of all components.

In some cases, even if there is an update, the button may remain inactive or show a message about the absence of new products. Here a little trick can help: in the update menu, click the three dots in the upper right corner and select "Select firmware file". If you pre-downloaded the official package, the system can use it to update, skipping the server verification step. OTA-The path requires an initial signal from the server.

⚠️ Note: Do not interrupt the installation process OTA-Update, even if it seems to be stuck in the "Waiting for a reboot" phase, interruption may disrupt the integrity of system files.

It is important to understand the difference between stable and developer versions of firmware. By default, Xiaomi Redmi 8 runs on a stable branch that receives updates less often, but is highly reliable. Switching to the developer branch through the update menu is impossible without unlocking the bootloader and special rights, so do not try to find such options in the standard menu.

💡

If the Wi-Fi update doesn’t load, try temporarily distributing the internet from another phone via a Bluetooth modem or USB-cable-change IP-link.

Once the boot is complete, the system will suggest restarting, which can take anywhere from 5 to 15 minutes, during which time the MIUI logo and progress scale will be displayed on the screen, during which time the phone can heat up, which is the normal reaction of the processor to intense data writing in flash memory.

Manual Update installation via Recovery Menu

If the automatic method did not work, you can use the manual installation method, which often allows you to update even when the OTA is silent. To do this, you will need to download the current firmware archive from the official website or proven resources, such as MIUI Download Hub. It is important to choose the file for your model (Olivalite encoding for the global version or Olive for the Chinese / Indian version), since installing incompatible firmware is impossible.

The downloaded file with the.zip extension needs to be placed at the root of the phone's internal memory. Then go back to the update menu, press three dots and select "Select firmware file." Find the downloaded file and confirm the action. The system will check the integrity of the file and, if all is well, prompt the installation. This method is good because it does not require an Internet connection at the time of installation.

There is an important caveat: manual installation through the menu is only possible if you upgrade to a newer version of the same branch (for example, stable to stable), or if the versions are the same, but different build. Attempting to roll back to an older version of Android through this menu will be blocked by the security system. If you need to downgrade the version, you will need a complete data cleanup or use Fastboot mode.

Update via Fastboot mode and computer

For advanced users or in cases where the phone does not load normally, there is a method of updating through Fastboot mode, USB-This method is the most powerful tool that allows not only to update, but also to fully restore the system in the event of serious failures.

The process begins with the smartphone switching to Fastboot mode: turn off the phone and press the power and volume buttons at the same time. The screen will show an image of a rabbit repairing an android. Connect the device to a PC, launch the Mi Flash Tool and indicate the path to the unpacked firmware folder. It is important to select the "Clean all" option to avoid file conflicts, but this will lead to complete deletion of data.

Using Fastboot mode requires special care. Incorrectly selected firmware (for example, designed for the Chinese version of the phone on the global device) can lock the device. In addition, cross-up (region change) often requires an unlocked bootloader, the procedure for obtaining which takes 168 hours of waiting after submitting an application to Xiaomi.

⚠️ WARNING: When running through Fastboot, never turn off the cable. USB And don't turn off your computer, and interrupting data transmission in this mode is almost guaranteed to lead to maintenance repairs.

If you are not confident in your abilities or do not understand the difference between the parts of the system, it is better to limit yourself to OTA methods or manual installation through Recovery.Fastboot mode is a tool for specialists that gives full control over the device, but also imposes full responsibility for the result on the user.

Solving Common Errors in Updating

During the update process, Redmi 8 users may encounter various bugs, the most common being “Failed to receive updates.” This problem often lies in the crowded cache of the Update app. To fix this, go to Settings → Apps → All apps → Update MIUI and click “Clear Data” and “Clear Cache”.

Another common problem is the file verification error when manually installed, which occurs if the firmware file is corrupted when downloading or does not match the region of the device, always check the checksum of the file (MD5 or SHA1) if you can, or simply download the archive again from another source, and also make sure that the file lies at the root of the memory, not in the folder with a deep nesting level.

Sometimes, after an upgrade, the phone may go into a bootloop cycle, in which case, try to go to Recovery mode and select Wipe Data, which will delete all data, but often saves the system after a major Android update. If this does not help, you will need to flash it through Fastboot.

💡

90% of update errors are due to unstable internet or lack of memory space, not hardware malfunctions of the phone.

It’s also worth mentioning the space shortage problem, which may not be obvious: the system may show 2GB of free space but require more for temporary files, in which case cleaning the MIUI folder in the file manager, where old logs and remnants of previous updates often accumulate.
