Owners of a popular budget smartphone Xiaomi Redmi 5A are often faced with the question of whether it is possible to install a more recent version of the operating system. Despite the fact that official support for this model from the manufacturer MIUI has already been completed, enthusiasts and technicians continue to look for ways to extend the life of the device. The process of upgrading the software can radically change the speed of the interface and close security vulnerabilities.
There are several ways to solve this problem: from a standard over-the-air update to manual installation of custom firmware via the mode Fastboot. The choice of a specific method depends on the current version MIUI, unlocking the bootloader and the technical skills of the user. It is important to understand that any manipulation of system files carries certain risks, so you need to carefully prepare before starting the procedure.
In this material we will analyze in detail the algorithms of actions for different scenarios, consider the necessary tools and pay special attention to precautions. You will learn how to check the relevance of the build, where to look for reliable sources of firmware and what to do if the phone stops booting after an unsuccessful attempt.
Checking the relevance of the current version of MIUI
The first step before any action is to diagnose the current state of the system. You need to know exactly which version Android and shell MIUI is currently installed on the device. This information is critical for selecting a compatible update file.
Go to the settings menu of your smartphone and find the section About the phone. By clicking on the version icon MIUI, you will start an automatic check for new packages from the manufacturer's servers. If the system reports that there are no updates, this does not always mean a dead end.
Sometimes server broadcasts occur in waves, and your device may simply not receive a signal yet. In this case, the manual method of downloading the firmware file from the official website will be a more effective solution. Pay attention to the build number, for example V9.6.1.0.MCCRUMIas it determines the region and type of device.
⚠️ Attention: Never try to install firmware from the global version (Global) on a device with Chinese firmware (China) without first unlocking the bootloader and completely clearing the data, otherwise the phone may turn into a “brick.”
Write down the current settings in a notepad or take a screenshot of the screen with system information. This will help you return to the original state in case of failure or compare changes after successfully installing new software.
Before starting any manipulations, be sure to back up all important contacts and photos to your computer or cloud storage, since the update process often requires a complete data reset.
Preparation of the device and necessary tools
Quality preparation is the key to successful completion of the procedure. You will need not only the smartphone itself, but also a high-quality USB cable, preferably an original one, since cheap analogues can cause interruptions in data transfer.
Make sure that the battery charge level is at least 60-70%. The flashing process consumes a significant amount of energy, and a sudden power outage at a critical moment can damage the system partition bootloader. Also free up space on your internal memory if you plan to download the file directly to your phone.
For advanced update methods, such as using Fastboot or TWRP Recoveryyou'll need a Windows computer. You should install drivers ADB and Fastbooton your PC, as well as specialized software to control the device.
- 📱 Charge your smartphone to at least 70% and disable energy-saving modes.
- 💾 Free up at least 4 GB of free space in the internal storage.
- 💻 Install Xiaomi USB Drivers and Platform-tools on your computer.
- 🔒 Make a complete backup of your user data to an external drive.
If you plan to unlock the bootloader to install custom firmware, you will need to create Mi Account and link it to the device a few days before the start of work. This is a mandatory requirement of the company's security policy Xiaomi.
Update methods: OTA, Recovery and Fastboot
There are three main methods for updating software on Redmi 5A, each of which has its own characteristics and scope of application. The choice depends on whether your bootloader is locked and what goal you are pursuing.
Method OTA (Over-The-Air) is the simplest and safest. It involves receiving updates directly through the phone's settings menu. This method is only suitable for official firmware versions that are still supported by the server.
The via method Recovery allows you to install the firmware file manually. You download the archive with the extension .zip, place it in the root of the internal memory and select the installation option in recovery mode. This method is often used to update within one region (for example, from Russia to Russia), but to a newer version.
The most complex, but universal method is firmware via Fastboot. It requires connecting to a computer and using the utility Mi Flash Tool. This method allows you to completely reinstall the system, change the region, or even roll back to an older version, but it definitely requires an unlocked bootloader.
| Update method | Need a PC | Unlocking BL | Saving data | Difficulty |
|---|---|---|---|---|
| OTA (Over the Air) | No | No | Yes | Low |
| Recovery (Manually) | No | No (usually) | Yes/No* | Average |
| Fastboot (Mi Flash) | Yes | Required | No (full reset) | High |
*When updating via Recovery, the choice of saving data depends on the type of downloaded archive (Recovery ROM marked "Clean" or "Update").
Installing firmware via Recovery mode
This method is ideal for those who want to update to a version newer than the current one, but do not want or cannot unlock the bootloader. You will need to download the firmware file format Recovery ROM from the official portal MIUI Downloader.
After downloading the file, rename it to update.zip to simplify search and place it in the root directory of the smartphone's internal memory. Do not put the file in folders, otherwise the recovery system may not see it.
Reboot your phone into Recovery mode. To do this, simultaneously hold down the power and volume up buttons until the logo Miappears. In the menu that appears, select a language (usually English and Chinese are available) and go to the item Install update.zip.
⚠️ Attention: If after selecting a file the system gives an error or writes "Can't verify update", it means that you are trying to install firmware from a different region or the version is too old/new for the current bootloader.
Confirm the action by pressing corresponding button. The process will take from 5 to 15 minutes. When finished, the phone will prompt you to reboot. The first launch after the update may take longer than usual, as the system optimizes applications.
☑️ Checklist before flashing
Full flashing via Fastboot and Mi Flash
If you want to get a “clean” system or change the device region, you will need the method Fastboot. This process irreversibly deletes all data, so make sure that the backup is done well.
Download the archive Fastboot ROM (extension .tgz) and unpack it on your computer to a folder with a short path, for example C:\mi_flash. There should be a folder with the system image inside. Run the utility Mi Flash Tool as administrator.
Put your smartphone into Fastboot mode by holding down the power and volume down buttons. Connect the device to the PC with a cable. In the Mi Flash app, press the Refreshbutton for the computer to detect the phone. The serial number should appear in the list of devices.
fastboot devicesThis command on the command line will also confirm the connection. In the Mi Flash interface, select the path to the unpacked firmware. At the bottom of the window, it is critical to select the firmware mode: clean all (complete cleaning) or clean all and lock (cleaning and re-locking the bootloader).
Press the button Flash and wait for the process to complete. The progress indicator will fill and the status will change to success. After this, the phone will automatically reboot into the new system.
What to do if Mi Flash gives an error?
Most often, errors like “Miss matching image and device” occur when you try to flash the global version on a Chinese device without unlocking, or when using an incompatible version of the bootloader. Solution: check the device region and use only the appropriate firmware, or unlock the bootloader officially through the Mi Unlock website.
Possible problems and ways to solve them
Unforeseen situations may arise during the update process. One of the most common problems is the “bootlap” - an endless reboot of the phone on the logo. This often happens when there is a version conflict or file corruption.
If the phone is stuck at the logo, try entering Recovery mode and performing a factory reset (Wipe Data). This will delete all user data, but may save the system from a cycle of reboots.
Another common problem is an error when verifying the file signature. This means that the integrity of the archive was violated during downloading or the file is not intended for your model. Always check the file checksums if they are provided by the source.
⚠️ Attention: The Recovery and Fastboot menu interfaces may differ depending on the Android version. If you see Chinese characters, be guided by the location of the buttons or use the translator in your phone to navigate.
If the phone stops responding to buttons and does not turn on at all (black screen), you will need to use the test mode EDL (Emergency Download Mode) and an authorized account for firmware, which is only possible in service centers.
Most errors when updating Redmi 5A are associated with an attempt to install firmware for the wrong region or interruption of the data recording process. Strictly following the instructions will minimize risks.
Frequently asked questions (FAQ)
Is it possible to update Redmi 5A to Android 10 or 11 officially?
No, official support Xiaomi Redmi 5A has ended at version Android 8.1 (Oreo) with MIUI 9 or 10 shell (depending on the region). Getting newer versions of Android is only possible through installing custom firmware (Custom ROM), such as LineageOS or Pixel Experience, which requires unlocking the bootloader.
Will the update erase my photos and contacts?
When updating via OTA or the Recovery method and selecting "Keep data", user data is saved. However, when flashing via Fastboot with the "Clean all" mode or installing custom firmware, the data is completely deleted.
Where can I download safe firmware for Redmi 5A?
The only safe source is the official website miui.com or trusted mirrors like xiaomifirmwareupdater.com. Avoid downloading files from suspicious forums or file hosting services without checking checksums.
What is bootloader unlocking and why do you need it?
Bootloader is a app that starts the operating system. The manufacturer blocks it to protect against unauthorized intervention. Unlocking is necessary to install custom recovery (TWRP), obtain root access and install unofficial versions of Android.
The phone says "System has been destroyed", what should I do?
This error means that the bootloader is locked, but you tried to flash unofficial or incompatible software. This can only be corrected by flashing the official stock firmware via Fastboot using an authorized account (in some cases) or contacting a service center.
