Owning a budget smartphone Xiaomi Redmi 5A often involves periodic maintenance of software. Over time, the operating system becomes overgrown with errors, applications stop working correctly, and the battery begins to run out faster than usual, in such situations, the most effective solution is a complete reinstallation of the operating system, or, as users say, “flashing”.
The process of restoring the shell requires attention and preparation, but it is not overly complex even for beginners. The key advantage of the recovery method through the computer is the ability to correct critical errors when the device stops booting or goes into an endless reboot cycle.
Before you take action, you need to be aware of the risks and follow the algorithm clearly. Mistakes can lead to loss of warranty or, in rare cases, to the failure of the device.However, if you act carefully and use verified files, your Redmi 5A will again become fast and responsive, as on the day of purchase.
The first and most important step is to prepare the workplace and to assemble the necessary tools. USB-The original cable provides stable data transfer, whereas cheap analogues often lead to a connection break at the most inopportune time.
You will need to download the official Mi Flash Tool from a trusted source. This software is designed specifically for working with devices based on Qualcomm processors that are installed in the Xiaomi Redmi 5A. You also need to find the firmware file itself, which should match your device model and region.
- 🔌 Original. USB-Micro-USB cable for reliable connection.
- 💻 Installed Windows operating system (versions 7, 8, 10 or 11).
- 📂 Downloaded archive with firmware (Fastboot) ROM) for Redmi 5A (codename riva).
- 🔋 Battery charge of the smartphone at least 60% to avoid sudden shutdown.
Drivers are worth paying special attention. Without the right ADB and Fastboot drivers, the computer simply won’t see the smartphone in the right mode. Usually they are installed automatically with the Mi Flash Tool, but in some cases, manual installation through Device Manager is required.
⚠️ Warning: Before starting the procedure, be sure to back up all important data. The Fastboot firmware process will completely destroy all information on the internal drive, including photos, contacts and messages.
There are two main types of firmware for Xiaomi devices: Recovery and Fastboot. For our case, when we use a computer for deep recovery, we need Fastboot ROM. These files have the.tgz extension and weigh significantly more than updates for OTA.
It is important to distinguish between global (Global) and Chinese (China) versions. Global firmware includes Google services and support for many languages, including Russian, out of the box. The Chinese version may require additional manipulations to install Russian and Google services, which complicates the process for the untrained user.
How to distinguish Fastboot ROM from Recovery?
Choosing the right version of the software is critical. If you try to install Chinese firmware on a global device or vice versa, the process may end in error or the device will turn into a brick. Always check the code name of the model, in the case of Redmi 5A it is riva.
You should also pay attention to the version of Android and MIUI. It is not always possible to roll back to the older version of the system due to the anti-rollback protection mechanism. Trying to install a version with a lower protection index can lead to irreversible locking of the bootloader.
Now, let's get to the practical part and prepare the files. The downloaded archive with the firmware should be unpacked into the root folder of the disk, for example, C:\xiaomi_rom\. The path to files should not contain Cyrillic characters or spaces, otherwise the firmware may not find the necessary scripts.
Once you unpack inside the folder, you'll see a lot of files and subdirectories. flash_all.bat Or the Mi Flash utility itself, which will point to this folder, make sure that the antivirus does not block the scripts, as they make changes to the system partitions.
☑️ Firmware readiness check
Launch the Mi Flash Tool on behalf of the administrator. In the program interface, click the "Refresh" button to make sure it works correctly. Then click the "Select" button and specify the path to the folder with the unpacked firmware.
At the bottom of the program window, you'll see three options: Clean all is the safest and most recommended mode. It cleans the memory completely and installs a clean system. Save user data tries to save files but often leads to errors, and clean all and lock lock locks the bootloader again, which can be dangerous if you've changed the region of the device.
To make your computer see your smartphone, you need to switch it to Fastboot mode. To do this, completely turn off the Xiaomi Redmi 5A. Then press the volume down and power button at the same time.
Hold both buttons for a few seconds until the image of a hare repairing an android appears on the screen, or an inscription that reads "FASTBOOT". In this state, connect the phone to the computer through USB-Windows Device Manager should have a device called Android Bootloader Interface".
💡
If the computer does not make a device connection sound, try another one. USB-port, preferably located on the back panel of the system unit, directly on the motherboard.
Once the device is identified, the Mi Flash Tool will show your phone's serial number in the list, signaling that the connection is established and you can start the process.
Press the "Flash" button in the upper right corner of the interface, and the data entry process will begin, and the program log will show up with progress messages: sending sparse 'system', writing 'system', etc. The entire process takes 300 to 600 seconds.
Do not disconnect the cable or touch the phone while recording. Interrupting the process during the recording phase of system partitions can damage the bootloader, after which the phone will no longer respond to buttons.
⚠️ Note: If a code error occurs during the firmware process, such as "error: cannot load image", immediately check the integrity of the firmware file and USB-Most often, the problem is poor contact.
Once all the steps are completed, the Mi Flash Tool status bar will be labeled "success" and the phone will automatically go into reboot. The first download after the firmware can last up to 10-15 minutes, as the system optimizes applications.
When the device turns on, you'll see a welcome screen with a choice of language, which means that the installation was successful, followed by the standard setup procedure: connect to Wi-Fi, log in to Google account and restore data from a backup.
The table below shows common error codes and ways to solve them, which can occur in the program log:
| Code/Message | Probable cause | Decision |
|---|---|---|
| Miss matching image and device | Wrong firmware model | Check the model code (riva) |
| Not enough space | Little space on disk C | Clear the disk or move the folder |
| Waiting for device | Phone is not in Fastboot mode | Reconnect the cable, press the buttons |
| Anti-rollback check failed | Attempted rollback version | Use a newer version of the software |
Sometimes users are faced with a situation where the phone after firmware requires activation through Mi Account. This is a standard protection against theft. You will need to enter the username and password from the account that was associated with the device previously. The forgotten password from Mi Account without access to the phone number is almost impossible to recover.
If the phone was bought by hand and the previous owner did not untie the device, you will have to look for the seller’s contacts, bypassing this protection by software methods is a complex procedure that goes beyond the standard instructions, and often requires paid services.
After successful installation and initial setup, it is recommended to perform several steps to optimize the work: remove pre-installed applications that you do not use to free up RAM. For the Redmi 5A with its modest characteristics, this is especially true.
Check for security updates already in the new system. Go to Settings → About Phone → System Update. You may get a small patch that fixes bugs in a particular firmware version.
💡
Successful firmware via Fastboot returns the smartphone factory speed and eliminates software errors accumulated over the years of use.
Recovery of Xiaomi Redmi 5A through a computer is a powerful tool that allows you to extend the life of the device.
If you have unforeseen difficulties in the process, don't panic. Most mistakes are solved by replacement. USB-The main thing is to keep your cool and read carefully the error messages in the program log.
