How to update Xiaomi Redmi 8A: Full instructions

Xiaomi smartphones are known for their availability and functionality, but over time, the software needs to be updated for stable operation. The owner of a budget device Redmi 8A often faces the need to improve performance or get new features of the MIUI. The system update process is not just installing beautiful icons, it is a critical stage of maintenance of the gadget, affecting the security of personal data.

Many users delay this procedure for fear of losing files or turning the phone into a brick. However, modern firmware methods from Xiaomi are as automated and safe as possible, while following simple rules. In this guide, we will discuss in detail all the available ways to transition to the latest version of the operating system, from standard settings to manual installation through the computer.

Before you start taking action, you need to understand the current state of your device. The Redmi 8A is based on a Snapdragon 439 processor, which has its own resource constraints, so following the instructions correctly is especially important. Ignoring the preparatory stages can lead to hanging or loss of information, which will require additional recovery time.

Preparation of the device for installation of a new version of the software

Any interference with system files requires prior preparation to minimize the risks. The first step should always be to back up all the important data: contacts, photos and messages. Although standard update methods usually store user information, human error or accidental power failure has not been canceled.

Make sure the battery is at least 60-70% charged, the process of writing new files to the phone's drive is energy intensive, and if the device shuts down in the middle of the procedure, recovery can take hours. Also check for free space in internal memory, as the installation package can weigh between 1.5 and 3 GB.

⚠️ Warning: Do not try to interrupt the upgrade process, even if the screen is gone or the phone seems to be getting stuck. 15-20 Forced reboot at this point is guaranteed to damage the bootloader.

For comfortable work, it is recommended to use a stable Wi-Fi connection, as mobile Internet can be unstable when downloading large amounts of data. Disable any third-party antivirus or memory cleaners that can block system installation processes.

• 🔋 Charge the battery above 60% or connect the charger.
• 💾 Free up 4GB of free space in internal memory.
• 📡 Connect to a reliable Wi-Fi network at high speed.
• 📱 Make a full backup of data to the cloud or PC.

Automatic updates through system settings

The easiest and safest way to get a new version of MIUI is to use the built-in update mechanism.The system will contact the Xiaomi server itself, check for the current build for your region and the Redmi 8A model.

To start the process, go to the settings menu and find About Phone. This shows the current firmware version and the button to check for updates. If the new version is available, you will see the corresponding notification and the ability to download the package.

When you boot, the system will suggest you restart, the phone will turn off, and the MIUI logo will appear on the screen with the progress bar, during which time the device can heat up, this is the normal reaction of the processor when you actively write data. Do not touch the control buttons until the desktop is fully loaded.

Sometimes automatic updates may not come immediately due to the servers’ phased deployment, in which case you can try changing the region in the settings or wait a few days until the package becomes available for your users. IMEI-address.

Manual installation via Recovery menu

If the automatic search does not yield results, you can use the method of manual installation, this requires you to pre-download the firmware archive from the official site or verified resources in.zip format.

Go to the About Phone menu and click on the MIUI version (e.g. MIUI Global 12.0.3). Quickly click 7-10 times on the version icon to activate the hidden file selection menu. Once the "Additional Features Enabled" notification appears, click on the three dots in the corner of the screen and select Select the firmware file.

The system will check the integrity of the archive, and if the hash amounts match and the version is newer than the current one, the installation process will begin, which allows you to update even if the servers do not update your device directly.

⚠️ Warning: Make sure that the downloaded firmware file is specifically designed for your model (model code usually starts with a letter, for example, M1906F7SH). Installation of firmware from another model will lead to inoperability of the device.

Update via computer with the Mi Flash Tool

For advanced users or when the phone doesn't load properly, there's a PC firmware method. You'll need the Mi Flash Tool and ADB/Fastboot drivers. This way you can do a clean installation by removing all the garbage from the system, but it requires care.

First, you need to unlock the bootloader if it is still locked, a procedure that requires a wait of 7 to 168 hours after you link your Mi Account to your device, and without an unlocked bootloader, you can't install global firmware through Fastboot.

Once you have permission to unlock, turn your phone into Fastboot mode (clambing the volume button when you connect the cable to your PC). In the Mi Flash Tool, select the path to the unpacked firmware and press the Flash button. The process will take from 3 to 10 minutes.

It is important to note that using the Fastboot method often requires a choice between cleaning up data (clean all) and saving it (save userdata). For the stability of the Redmi 8A after changing the version of Android or a large version of MIUI, it is better to choose a full cleanup.

Solving errors during the update

There may be a number of errors during the update process, the most common being “Failure to check the update” and this may be caused by server-side issues, modified system files (root rights) or crowded cache.

If you have a Root rights or a modified bootloader installed, the standard update will likely not pass the integrity check, in which case you will need to completely reset or flash through the computer and clean all partitions.

The problem can also be a lack of space, where the system creates temporary files when unpacking, and if the place ends at a critical moment, the process will stop, clear the app cache and delete unnecessary videos before starting the procedure.

💡

If the update freezes during the File Check phase, try to turn off the Internet (Wi-Fi and mobile data) before clicking the Start Update button, which will cause the system to skip checking the online signature and use the local file.

In some cases, resetting network settings or changing the network helps. DNS-This allows you to bypass the ISP locks if Xiaomi servers are not available in your region.

Optimization after installing a new version

Once the update is completed, the system begins to optimize applications in the background, and in the early hours of the service, Redmi 8A can run slower than usual, warm up and discharge faster, which is a normal process of recompilating the application code for the new version of Android Runtime.

It is recommended that the phone be left lying down with the screen on and Wi-Fi connected for about 30-60 minutes after booting, allowing the system to complete all background indexing processes without user intervention.

Check the basic functions: calls, Wi-Fi, Bluetooth and cameras. If you notice abnormal behavior, try resetting to factory settings, but after the update, this ensures that the configuration files are clean.

💡

The first 24 hours after a major MIUI update is the system adaptation period. Don't panic about a temporary loss of autonomy or speed.

Be sure to check for embedded app updates through the GetApps store or Google Play, as system components could also get new versions for compatibility with the updated firmware.
