The smartphone Xiaomi Redmi 6 Pro, released in 2018, was initially based on the Android 8.1 Oreo operating system with the proprietary MIUI 9 shell. For many users of this model, the issue of getting more latest software versions, including Android 9 Pie and MIUI 10/11, which were officially released by the manufacturer. Software updates are not only new interface functions, but also critical security patches that correct system vulnerabilities.
The process of installing new firmware can be performed in several ways: through the standard settings menu, manually through Recovery mode or using a computer. The choice of method depends on the current system version, device region, and availability of access to global update servers. In this article, we will analyze in detail all the steps necessary for a successful transition to the current version of the software.
It is worth noting that official support this model ended on version MIUI 11 (Android 9), so installation of newer versions of Android (10, 11, 12 and higher) is only possible through third-party solutions, such as custom firmware. We will focus on safe methods of updating to the latest official version available for your device to avoid voiding the warranty or damaging the device.
Preparing your device for a system update
Before you begin any manipulation of system files, you must complete a number of preparatory steps. This will minimize the risk of data loss and ensure process stability. The first step is to create a complete backup of all important information: contacts, photos, messages and application settings. Use built-in tools or cloud services to synchronize data. Also make sure that you have enough free space on your internal drive or memory card - typically 3 to 5 GB of free space is required to download and extract the installation package. backup copy all important information: contacts, photos, messages and application settings.
Use built-in tools MIUI or cloud services Google to synchronize data. Also make sure that you have enough free space on your internal drive or memory card - typically 3 to 5 GB of free space is required to download and extract the installation package.
⚠️ Warning: Updating the system may delete user data if you select the full wipe option. Always make a backup to external media or to the cloud before starting the procedure.
The second critical condition is the battery charge level. The device should be charged at least 60%, and preferably 80-90%. Interrupting the firmware process due to low battery can lead to irreversible consequences, including brick (turning the phone into a “brick”). Connect your smartphone to a power source or make sure the battery is stable.
☑️ Checklist before updating
Finally, check the stability of the Internet connection. Downloading large firmware files requires a reliable communication channel, preferably Wi-Fi, to avoid download interruptions and file corruption. Mobile traffic can be unstable and consume a significant amount of data.
Checking the current version and model of the device
Before looking for files to update, you need to accurately identify the modification of your smartphone. The line Redmi 6 Pro has different regional versions (Global, China, India, Russia), and the firmware intended for one region may not work on another or cause errors in the operation of communication modules.
To view information, go to menu Settings → About phone. Here you are interested in the line “MIUI Version” and the device type. Make a note of this information as you will need it when selecting a file for manual installation. Also pay attention to the status of the bootloader: for a standard update through the menu, it must be unlocked only in rare cases, but for custom solutions this is a prerequisite.
The table below shows the main differences between firmware versions that the user may encounter:
Version for China with a full range of Chinese services| Firmware type | Description | Region | Stability |
|---|---|---|---|
| Global Stable | Official stable version for the world market | Global | High |
| China Stable | China | High | |
| Developer (Beta) | Test version with new functions, but possible errors | Any | Medium |
| Recovery | Full system image for installation via the recovery menu | Depends on the version | High |
It is important to understand the difference between Recovery and Fastboot firmware. To update via the file selection menu on the phone itself, you need an archive with a .zip (Recovery) extension. .img files intended for flashing via a computer and the Mi Flash utility are not suitable in this context and can be dangerous if used incorrectly.
Automatic update through settings (OTA)
The easiest and safest way to get a new version of the software is to use the built-in OTA (Over-The-Air) mechanism. The system independently checks the servers for updates that are compatible specifically with your device modification. This method is ideal for inexperienced users, as it eliminates the human factor when selecting files.
To start the process, open the application Settings and find the item About phone. The current MIUI version will be displayed at the top of the screen. Click the logo or the "Check for updates" button. If a new version is available, the system will prompt you to download and install it.
In some cases, automatic updates may not immediately arrive on all devices due to the gradual deployment of servers. If you are sure that a new version has already been released, but there is no notification, try changing the device region in the settings (Settings → Additional settings → Region) to the country where the release took place earlier, for example, India or Russia, then run the check again.
After downloading the file, the system will ask to reboot. The screen will go dark and the installation process will begin, which may take 5 to 15 minutes. At this time strictly prohibited turn off the phone or remove the battery (if it is removable). Upon completion, the smartphone will turn on with the new version of the software.
Manual installation of the update via Recovery
If the automatic search does not produce results or you want to update to a specific version, bypassing server queues, use the manual installation method. To do this, you will need to download the firmware archive in .zip format from the official website or a trusted source. Make sure that the file is intended specifically for Redmi 6 Pro (code name sakura).
Copy the downloaded file to the root directory of the smartphone’s internal memory. Don't put it in deep folders so that the system can find it easily. After that, go to the update menu: Settings → About phone → MIUI Version. Click on the three-dot menu in the upper right corner and select “Select firmware file.”
⚠️ Attention: Make sure that the downloaded file has a .zip extension and is a Recovery firmware. An attempt to install Fastboot firmware (.img) through this menu will result in an error.
The system will check the integrity of the file. If everything is correct, a confirmation window will appear. Click "OK" and wait for the process to complete. The phone will automatically enter update mode. Unlike OTA, a constant Internet connection is not required here, which makes the method convenient when the connection is unstable.
What to do if the system writes “The file cannot be verified”?
This message often appears when trying to downgrade the software version or when installing firmware from a different region. In such cases, a complete data wipe or unlocking the bootloader is required.
Using Recovery mode for reset and installation
The built-in Recovery menu in Xiaomi allows you not only to install updates, but also to perform a factory reset, which is often recommended after major Android updates for the system to function correctly. This menu is accessed using a key combination when the device is turned off.
To enter Recovery mode, turn off the smartphone completely. Then press the Volume+ and Powerbuttons simultaneously. Hold them until the logo Miappears, then release the power button while continuing to hold the volume down. A menu will open with several items in English and Chinese.
Navigation is carried out using the volume buttons (up/down), and the selection is confirmed with the power button. You need an item Wipe Data for cleaning or Connect with MIAssistant to connect to a PC. However, to simply install the firmware via Recovery, it is more convenient to use the standard menu described in the previous section, or mode Apply update from storage (if available in your version of Recovery).
After successfully installing a new system, it is strongly recommended to reset the settings (Wipe Data/Factory Reset), especially if you are moving from Android 8 to Android 9. This will remove software junk and conflicts of the old ones settings, ensuring maximum performance.
After updating the system and turning it on for the first time, give the smartphone 15-20 minutes to optimize applications in the background. During this time, the device may heat up and work slower - this is a normal process.
Possible errors and ways to solve them
During the update process, users may encounter various errors. One of the most common is “The file could not be verified.” This is often due to a violation of the integrity of the downloaded archive or a region mismatch. Solution: Recheck the hash of the file or download it again from another source.
Another common problem is “bootloop”. If after the update the phone reboots endlessly, try entering Recovery and doing Wipe Cache i Wipe Data. If this does not help, you will need to flash it through your computer using the Mi Flash utility and Fastboot mode.
Errors related to lack of space may also appear. In this case, free up memory by deleting application cache, old videos, and unused files. The system must have a reserve of free space not only for storing the file, but also for temporary operations.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of MIUI and the system language. If you are not sure of your actions, consult with official sources or experienced users.
Most update errors are associated with unstable Internet, low battery, or incorrect choice of firmware file. Careful preparation solves 90% of problems.
