The Redmi 8A series has earned the status of “people’s” due to its excellent price-performance ratio, but over time, the standard operating system may no longer meet the requirements of modern applications. Many owners are wondering how to update the Android version on the Xiaomi redmi 8a to get new security features, a fresh MIUI interface and battery optimization. The upgrade process does not always happen automatically, and sometimes the user has to take the initiative to install the current build.
In this article, we will take a look at all available firmware methods, from standard air updates to manually installing archives through the Recovery menu. You will learn how to properly prepare your device, where to download official files and what to do if the system writes that there are no updates. A competent approach to the procedure will prolong the life of your gadget and keep it relevant.
Before you start any software manipulation, it is critical to create a complete backup of all your data.Even the most secure method can theoretically crash, and losing photos or contacts would be an unpleasant surprise.Use Xiaomi Cloud, Google Photos or the built-in local backup feature to save important information to an external medium.
Checking the current version and preparing the device
The first step before any action is to thoroughly diagnose the current state of the system, you need to know exactly which version of MIUI and Android is installed right now to understand whether there is a point in updating or you are already on the last available build for your region. Often users try to update, even though their device has already received all possible updates from the manufacturer.
To check, go to the settings menu and select About Phone, which displays all the key information: build number, Android version and update status. Pay attention to the MIUI version number, as global and Chinese firmware may have different numbering and security patch schedules. If the version number matches the last officially released for your region, manual installation may not give you an increase in the Android version, but only reinstall the current one.
⚠️ Warning: Make sure that the battery is at least 60% battery power before the process begins.Installation interruption due to battery discharge may cause damage to the system partition and inability to load the device.
It is also worth freeing up space in internal memory, since firmware archives can take up from 2 to 4 GB. Temporary files, application cache and old downloads should be deleted or transferred to the computer.
💡
Before upgrading, remove all third-party launchers and antiviruses, as they may conflict with the system file installation process.
Automatic update via OTA (over the air)
The easiest and safest way to get a new version of software is to use the built-in OTA (Over-The-Air) mechanism, which does not require a connection to a computer, special cables or deep technical knowledge.
To initiate a manual update search, open the Settings app, then go to About Phone and click on the MIUI logo in the center of the screen. The system will contact the update server. If a new version is released for your model and region, a Download button will appear, otherwise you will see a message that the latest version is installed.
- 📶 Stable connection: Use a reliable Wi-Fi network as data can exceed 2 GB and mobile internet can be interrupted or charged.
- 🔋 Flight mode: During download and installation, it is recommended not to use the phone actively to avoid overheating of the processor.
- 🚫 No Root Rights: If a Super User (Root) is obtained on a device, an automatic update can be blocked or result in a cyclical reboot.
It's important to understand that updates come in waves, and even if the new version is officially released, it can be delayed by days or even weeks on your particular smartphone, which is a common practice for engineers to track possible errors on the first batches of devices.
Manual installation via Recovery menu
If the automatic search is not working and the new firmware version is already in place, you can use the manual installation method, which requires you to download the.zip firmware archive from the official website or proven resources, and the main advantage of the method is the ability to upgrade to a newer version, ignoring the regional limitations of the phased rollout.
The downloaded file must be renamed update.zip and placed at the root of the device's internal memory (not in the folder, but immediately in the main storage), then go back to the system update menu, click on the three dots in the upper right corner and select "Select the firmware file", the system will check the integrity of the archive and suggest starting the installation.
The path to the file: /storage/emulated/0/update.zipThis method allows you not only to update, but also to roll back to older versions if the new version does not work. However, when the version rolls back, all data will be deleted, so be sure to make a full backup. The installation process takes from 5 to 15 minutes depending on the amount of changes and memory speed.
⚠️ Warning: Never interrupt the installation process, even if the phone is stuck on the logo.A forced reboot at this point is guaranteed to cause a software crash (bootloop).
☑️ Checklist before manual installation
Update via computer and Mi Flash Tool
For advanced users who are faced with serious errors or want to completely reflash the device “clean”, the method is designed using a PC. This method requires an unlocked bootloader to install global firmware on Chinese versions or change the region. The Mi Flash Tool allows you to install the system cleanly by removing all user data and cache.
Unlike the Recovery method, it uses firmware in.tgz format (Fastboot). ROM), The phone is converted to Fastboot mode by pressing the volume button when connected. USB-The computer must recognize the device as Android Bootloader Interface.
The installation process through Fastboot takes longer and requires care. Incorrect firmware (for example, for another model) can “brick” the device, making it possible to restore it only in the service center. Always check the code name of the device (for example, olive for Redmi 8) before downloading files.
| Parameter | Recovery ROM | Fastboot ROM |
|---|---|---|
| File extension | .zip | .tgz / .tar |
| I need a PC. | No. | Yes. |
| Unlocking BL | Not required | Required (often) |
| Data retention | Yes (on update) | No (full reset) |
| Difficulty | Low. | Tall. |
What if the Mi Flash Tool can't see the phone?
Solving Common Errors During Updating
During the upgrade process, users of Xiaomi Redmi 8A may experience a variety of system errors, and one of the most common problems is the message “No updates were received”, which can be caused by unstable Internet, crowded MIUI servers or a change in the region in settings.
Another common problem is the file verification error when manually installed, the system says "File can't be verified" or "failed to verify." This happens if the firmware file is corrupted when downloaded, has the wrong name or is intended for another model, and the error will occur if you try to roll back to an older version without completely resetting the data.
- 🔄 Change region: Try temporarily changing region in your phone settings to India or Global, check for updates and return it back.
- 🗑️ Cache Clearing: Before retrying to clean the app's cache, Update through the app management menu.
- 💾 File system: Make sure that the firmware file is in the internal memory, not on the computer. SD-map, as access to the card may be blocked during the update.
If the phone starts to run slower or discharge quickly after the upgrade, it is recommended to perform a full reset (Wipe Data) through the Recovery menu.This will delete all data, but it is guaranteed to eliminate conflicts between the old and new version of the system.
💡
Most of the “failed to verify” errors are solved by re-downloading the firmware from another source or changing the Wi-Fi network.
