Xiaomi smartphone owners often face limitations of regional firmware versions, which may not contain certain features or pre-installed services. The global Indonesian firmware for the Redmi Note 9 Pro (codename curtana) is attracting users with optimization and stable operation of communication modules across Asian and European networks, and the transition to this region allows access to specific camera settings and an updated shell. MIUI, The Indonesian market is often entered before others.
The process of changing the regional version of the software requires careful preparation and understanding of the risks associated with modifying system files. Installation of the Indonesian version is possible only through Fastboot mode with complete cleaning of the device data. You will need not only the firmware itself, but also specialized software, as well as an unlocked bootloader, which is critical to the successful completion of the operation.
In this article, we will discuss in detail all the stages of preparation, finding the right image of the system and the immediate process of flashing. We will look at the nuances of working with the Mi Flash Tool utility and answer questions that arise when working with ADB drivers. Follow the instructions Step-by-step to avoid errors and turn your smartphone into the desired modification.
Preparation of equipment and software
Before you start any manipulation of the system partition, you need to make sure that all the components are available. You will need a personal computer running the Windows operating system, since the main tools work in this environment. The USB cable should be original or high-quality analogue, capable of transmitting data at high speeds, not only charging the battery.
The charge of the device should be at least 60-70%, so that in the event of unforeseen delays in the recording process, the smartphone does not turn off. Critical discharge during firmware can lead to irreversible damage to the bootloader, turning the phone into a “brick”.
On the computer you need to install the latest drivers for Xiaomi and Qualcomm devices. Without properly working drivers, the system will not be able to recognize the smartphone in Fastboot or EDL mode. You will also need to download and unpack the archive with the firmware itself, making sure that it is intended for the Redmi Note 9 Pro (curtana) model, and not for the Redmi Note 9 (merlin) or Pro Max (gauguin).
⚠️ Attention: Using firmware from another smartphone model will lead to hardware failure and software failure, which cannot be corrected by software methods at home.
Unlocking the Bootloader bootloader
Xiaomi’s official policy prohibits installing software from regions other than the one the device was released to without unlocking the bootloader, a security mechanism designed to protect the user from malware, but it is also a major obstacle for enthusiasts. First, you need to link your Mi Account account to the device in the settings menu.
Once you have your account linked, you need to apply for unlocking via the official Mi Unlock Tool.The process is not instantaneous: the security system may require waiting from 7 to 168 hours (3-7 days) before issuing a permit. During this time, you can not log out of your account on your smartphone or reset your settings, otherwise the timer will reset.
When the wait period expires, connect your phone to your PC in Fastboot mode (pressing both the power and volume buttons). Launch the Mi Unlock Tool, log in to your account and press the unlock button. The device will be completely cleared and the bootloader status will change to Unlocked.
Finding and Choosing the Right Firmware
The most important step is to find the correct system image file. ID in the file name (for example, miui_IDGlobal...). Firmware is divided into two types: Recovery (update via the phone menu, is not suitable for changing the region without root rights) and Fastboot (full image for flashing through the PC).
You need a Fastboot for yourself. ROM. The file will have a.zip extension, inside which after unpacking there are many files and folders, including a script. flash_all.bat. It is important to check the Android version and MIUI: For the Redmi Note 9 Pro current versions based on Android 10, 11 or 12, depending on the desired stability.
You should only download images from trusted sources, such as the official website miui.com or authoritative archives like Xiaomi Firmware Updater. Files from questionable forums may contain modified system code or viruses. Make sure that the path to the folder with unpacked firmware does not contain Cyrillic characters or spaces so that the firmware utility correctly counts the paths.
Where to find the exact version of the firmware?
Instructions for firmware through Mi Flash Tool
The process of recording a new image of the system is carried out using the Xiaomi Mi Flash Tool utility. This is the official software that interacts with the phone at a low level. After launching the program and connecting the smartphone in Fastboot mode (screen with a hare or Fastboot logo), the device should be determined in the list of connected devices.
Press the Select button and point the path to the folder with Indonesian firmware unpacked. At the bottom of the utility window, select clean all mode. This option is critical: it completely erases all memory partitions and installs a clean system, which is necessary when changing the region.

Solving common mistakes and problems
One of the most common bugs is Error: Missmatching image and device, which occurs when you try to flash the firmware from Redmi Note 9 (merlin) to Redmi Note 9 Pro (curtana) or vice versa, in which case the process will stop at the initial stage, and you will have to re-find the correct image file.
Another common problem is Error driver error: Can not find MIPHONE or no device in the list, which is solved by manually installing drivers through Windows Device Manager. Find a device with a yellow icon or an unidentified device, select the driver update manually, and specify the path to the x86 or x64 folder inside the Xiaomi driver installer.
If the process is stuck in the Waiting for device or sending sparse step, try changing the process. USB-Port (Preferred to use ports) USB 2.0 It's sometimes helpful to reboot your phone to Fastboot mode again. Don't panic if it doesn't turn on for a long time after you've flashed it. MIUI may last 10-15 minute.
⚠️ Note: If the utility gives an error "Anti-rollback check failed", then you are trying to roll back to an older version of Android than the one installed now.
Setup and optimization after installation
After successfully installing Indonesian firmware and first turning on, you will be greeted by a greeting screen in English or Indonesian, select the desired language (Russian is usually present in global versions) and connect to Wi-Fi. The system may suggest upgrading to a more recent version of MIUI - this is normal practice, since the factory firmware could have been released several months ago.
Indonesian versions of MIUI often have different configurations for battery algorithms and aggressiveness of closing background applications, and it is recommended to immediately go to the battery settings and set background activity limits in No Limits mode for important messengers (Telegram, WhatsApp).
💡
After the first download, uninstall the pre-installed Indonesian apps (Bloatware) you don’t use via settings or ADB to make room and speed up the work.
Also worth checking is NFC and geolocation, and in some cases, after a region change, you may need to recalibrate your sensors, go to the engineering menu, dial ##6484## in your phone, and test the main modules: touch screen, vibration, sound and cameras.
💡
Indonesian firmware often performs more consistently than European firmware in poor signal conditions, but may have differences in the set of pre-installed Google services.
