Ownership of the Xiaomi Redmi 9A Chinese version (CN) often comes as a surprise to the user when it turns out that the system does not have Google Play, and the interface is in Chinese. Chinese MIUI firmware, even based on Android 10 or 11, do not have Google services pre-installed, making the smartphone almost unsuitable for use in Europe and the CIS without deep modification.
Reflashing Xiaomi Redmi 9A requires care and strict adherence to the sequence of actions, since an error at any stage can lead to the inoperability of the gadget. You will work with the bootloader, drivers and specialized software from the manufacturer. Despite the apparent complexity, the technique has been worked out for years and allows you to turn the “Chinese” into a full-fledged Global smartphone in one hour.
Before you start taking action, you need to understand the risks and prepare the workplace. For Redmi 9A, it is critical to use Fastboot firmware, labeled Global, since the Recovery method will not work here due to the region locks. Next, we will discuss all the stages of preparation, configuration of the computer and the device itself for successful software replacement.
Preparation of equipment and software
The foundation of successful reflashing is a quality cable USB well-functioning USB-Cheap cables bundled with some accessories are often designed only for charging and do not provide stable data transfer, which will lead to a connection break at a critical moment. It is recommended to use the original cable or certified analogue with support for high-speed data transfer.
The second important component is a Windows computer, which is where the basic drivers and utilities of the Mi Flash Tool are available. On macOS or Linux, the process is much more complicated or impossible without virtual machines, so it's better to find a PC or laptop with Windows 10 or 11 in advance.
You will need to download and install the following software set:
- 📦 Mi Flash Tool – the official utility for firmware Xiaomi devices in Fastboot mode.
- 🔌 Xiaomi USB Drivers – drivers that allow the computer to recognize the smartphone in different modes of operation.
- 📂 Fastboot ROM Global – a firmware file with the.tgz extension specifically designed for Redmi 9A (codename).
- 🔓 Mi Unlock Tool – a program to unlock the bootloader if it is still closed.
⚠️ Attention: Using firmware from unverified sources can lead to malware installation or damage to system partitions. ROM-files only from official resources or trusted portals like Xiaomi Firmware Updater.
Unlocking the bootloader (Bootloader)
Chinese versions of Xiaomi smartphones come with a locked bootloader that does not allow you to install software from other regions. Without this procedure, all further actions are meaningless. The unlock process requires linking the Mi Account to the device and waiting for a certain time set by the manufacturer.
First, you need to activate the developer mode. To do this, go to the settings, find the "About Phone" item, and quickly click on the MIUI version seven times. Then the "Advanced Settings" menu will appear "Developers" option, and you need to turn on "Debug on USB" and "Unlock the bootloader".
The following actions should be followed:
- 🔗 Link the Mi Account in the bootloader unlock menu (requires a SIM card and the Internet).
- ⏳ Wait 168 hours (7 days) from the moment of the link without leaving the account.
- 💻 Run Mi Unlock Tool on PC and log in to the same account.
- 📱 Turn your phone into Fastboot (clip the volume down) + power) and connect to the PC.
- 🔓 Press the Unlock button in the program and confirm the action.
Once successfully unlocked, the phone will be completely cleared of user data, which is standard security procedure. If you plan to save data, back up in advance, although if you change region from CN to Global, you will still need to do this again.
Finding and Preparing the Right Firmware
The most critical step is choosing the right firmware file. There are many modifications to the Redmi 9A, and installing the wrong version will lead to an error or a brick. You need a Global Stable Fastboot firmware. It's important to pay attention to the code name of the device: for Redmi 9A, it's dandelion.
The firmware file has the extension.tgz and weighs about 3-4 GB: After downloading, the archive must be unpacked into the root of the C disk or any folder with a short path, for example. C:\ROM\. The path to the folder should not contain Cyrillic or spaces, otherwise the Mi Flash Tool will not be able to find the files.
Inside the unpacked folder should be the directory images and script flash_all.bat. It's the image folder that shows that it's a full-fledged firmware, not a part of it. If you see only one file or structure other than the standard one, download the archive again.
Where can I find the official firmware?
Installation of Global ROM through Mi Flash
Once you've got it all ready, you can go to the firmware itself. Run the Mi Flash Tool on behalf of the administrator. In the program interface, click the "Select" button and point the way to the unpacked firmware folder. The program automatically checks the files and displays them in the list.
Put your smartphone into Fastboot mode. To do this, you need to press the device off with a volume button and, holding it, connect the USB cable to the computer, and the image of a rabbit repairing an android will appear on the screen, which means the correct mode of operation.
In the Mi Flash Tool, click "Refresh" and the device with its serial number should appear in the list. Below, in the firmware method selection menu, make sure that the clean all value is selected. This option will completely clean the phone's memory and install a clean system without saving debris from Chinese firmware.
☑️ Checklist before firmware
Press Flash and wait until the process is over. The status bar will show progress. The whole procedure takes 200 to 600 seconds. Once completed, the phone will automatically restart. The first boot can last up to 10 minutes -- that's OK, the system is being optimized.
⚠️ Warning: Do not disconnect the cable or interrupt the process until the indicator in the Mi Flash Tool is green with the words "success.
Typical errors and methods of their elimination
When you flash the Xiaomi Redmi 9A, users often encounter bugs, and one of the most common is "Missmatching image and device," which means you're trying to flash the firmware from a different model or region than the bootloader's current state, and the solution is one: double-check the code name and the ROM version.
Another common problem is the “Waiting for device” error or the phone’s missing list, which indicates a driver problem. Windows Device Manager should not have a yellow exclamation point when connecting in Fastboot mode, and if any, drivers should be manually updated through Device Management.
The table below will help diagnose the problem by the error code or symptom:
| Symptom/Error Code | Probable cause | Decision |
|---|---|---|
| Mistake 1 (Flash Error) | A firmware file or cable is damaged | Remove ROM, replace USB-cable |
| Device not defined | There are no ADB/Fastboot drivers. | Install Xiaomi USB Drivers again |
| Authorization error | Mi Unlock account is incorrect | Log in to the same account as on your phone |
| An endless reboot | Failure to install or break partitions | Repeat the procedure in Clean All mode |
If the phone has gone into an endless bootloop, try pressing the power and volume button up to log in to Recovery, select Wipe Data and then Reboot. If that doesn't help, you'll need to re-running through Fastboot.
💡
Use it. USB-port 2.0 (black) if you have connection problems. USB 3.0 (blue) sometimes cause driver conflicts when firmware is used on older Xiaomi models.
Initial configuration and installation of Google services
After successfully installing Global firmware, you will see a welcome screen in your chosen language. MIUI Global already has Google services built-in, so install separately. GMS (Google Mobile Services through APK-No files required. Just log in to your Google account when you first set up.
However, in the Chinese versions, there are sometimes artifacts in the form of system applications in Chinese. After the first download, it is recommended to go to the settings, the Apps section, and remove or disable unnecessary system programs if they interfere. It is also worth checking the system updates in the About Phone paragraph, as the new firmware may not be the latest.
For full work it is recommended:
- 🌐 Check the date and time settings (automatic network).
- 🔒 Install a security patch if it is available in the update.
- 📲 Download the necessary applications from the Google Play Store.
- 🗑️ Remove Chinese software that may have remained in the system.
Now your Redmi 9A is fully adapted for use outside of China, you have access to the Play Market, navigation, YouTube and other services that were previously unavailable, and the system will work steadily, receiving official security updates.
⚠️ Note: After the region change to Global, some banking applications may require a re-security check, which is normal because the digital signature of the system and the region of the device have changed.
💡
The Redmi 9A is only possible to successfully reflash the Fastboot mode and the original drivers. The Recovery method to change region from CN to Global does not work due to bootloader locks.
