The question of when to update Xiaomi Mi 9, remains one of the most discussed among the owners of this legendary flagship. the device, released in 2019, has gained enormous popularity thanks to the powerful processor Snapdragon 855 and a quality camera, but with the release of new versions of the Android operating system and the shell MIUI (now HyperOS), owners are increasingly thinking about the future of their gadget. Xiaomi’s policy involves supporting flagship models for 2-3 years with major Android updates, after which they go into the mode of only security patches or stop supporting altogether.
The software situation for Xiaomi Mi 9 (codenamed cepheus) has stabilized, and it is important for fans of the device to understand the real situation, so as not to wait for the release of versions that are not officially planned. Official support for the main versions of Android for this model ended on Android 11 with the shell of MIUI 12.5, although some regions and global versions have received experimental builds based on Android 12. It is important to distinguish between official releases and custom solutions, since the wait for an “official” update can be delayed forever.
In this article, we will take a closer look at the update schedule, explain why MIUI 12.5 Global Stable is the latest official stable version for the global market, and provide guidance for those willing to take the risk of installing more recent versions through third-party methods. Understanding the update structure will help you make an informed decision: stay on the current version for stability or look for alternative ways to develop your smartphone.
Official Support Status and Version Release Schedule
The Xiaomi Mi 9 update story is a classic example of the life cycle of a flagship device.The smartphone came with Android 9 Pie and consistently received major updates to Android 11. The MIUI release schedule for this device was quite tight in the first two years, but then Xiaomi shifted focus to the newer Mi 10 and Mi 11 series. Technical support for the Snapdragon 855 chipset by Qualcomm also played a role in limiting the number of available versions of Android.
Many users mistakenly believe that if a device is powerful, it should receive updates forever. However, software manufacturers are guided by agreements with component suppliers and marketing strategy. For the cepheus (Mi 9), the cycle of major OS updates is over, which means that waiting for the official MIUI 13, 14 or HyperOS based on Android 12, 13 or 14 from the global office of Xiaomi is not worth waiting.
However, in some regions, such as China or India, the charts may have slightly differed, but the global trend is the same: If you're waiting for a security patch, it may not come regularly or at all, as the device has been upgraded to EOL (End of Life) status on most support lists. The official status of the device now can be described as "completed," opening the way for the development community.

Technical limitations of the Snapdragon 855 chipset
The fundamental reason that affects when the Xiaomi Mi 9 will be updated (or not updated) is the processor architecture. Qualcomm Snapdragon 855, despite its outstanding performance in its time, has limitations in drivers and support for new Android features introduced in versions 12 and above. Xiaomi, like other vendors, depends on the readiness of drivers from Qualcomm for specific SoCs (System on Chip).
The move to Android 12 required changes in the structure of system partitions, the introduction of Project Treble in a new format and updated security mechanisms that did not always correctly fall on the old implementations of the BSP (Board Support Package) for the 855th snippragon. That is why many manufacturers, including Xiaomi, Samsung and OnePlus, have stopped on Android 11 for this generation of devices. Hardware compatibility is a key factor that can not be circumvented by software crutches without losing stability.
It is worth noting that the lack of official updates does not mean that the hardware does not pull. Xiaomi Mi 9 is still able to work quickly and smoothly even on modern versions of Android, as proven by independent developers. OTA-Over-The-Air, platform technical limitations become ceiling.
The table below shows a comparison of support for different MIUI versions on the Xiaomi Mi 9:
| MIUI version | Android version | Status of support | Type of updates |
|---|---|---|---|
| MIUI 10 | Android 9 | Completed. | Archives |
| MIUI 11 | Android 10 | Completed. | Archives |
| MIUI 12 / 12.5 | Android 11 | Completed (EOL) | Security patches (rarely) |
| MIUI 13+ | Android 12+ | Not supported | Absent (officially) |

Why Xiaomi Mi 9 won’t get new versions of Android
The answer to why Xiaomi Mi 9 has stopped receiving major upgrades is economic and technical: Developing a new version of the shell for an old device requires the resources of engineers, testers and project managers. When new models come to market, they are given priority, as they generate the main revenue of the company.
There is also the concept of “Google Certification”. GMS" (Google Mobile Services: For a device to be legally distributed with new Android versions and Google services, it must be certified. For older models whose support cycle has expired, the company may not see the point in spending the budget to re-certify each new version. MIUI. The economic model dictates its rules: support for the device usually lasts 2-3 year.
New features like Material You, a redesigned control center and widgets require deep integration into the system. Tightening these features onto the old MIUI 12.5 code could lead to bugs that are difficult to fix after the fact. So Xiaomi decided to keep the device on a stable but old version so as not to worsen the user experience with errors.

Alternative paths: custom firmware and GSI
If official channels are closed, a community of enthusiasts takes to the scene. Xiaomi Mi 9 has one of the most active development communities in the world (XDA Developers). Thanks to the unlocked bootloader, users can install custom firmware based on Android 12, 13 and even 14. This is the only real way to upgrade the phone to current versions.
Popular projects like LineageOS, Pixel Experience (or its forks), ArrowOS and crDroid offer pure Android without Xiaomi’s excess software.These firmware often run faster and more stable than official heavy shells. MIUI But the installation requires skills: unlock the loader, install a custom Recovery (TWRP Or OrangeFox and flash ZIP-archive.
It is important to understand the risks. When installing unofficial software, you lose your warranty (although it is likely already expired for the Mi 9), some camera functions may stop working due to the lack of proprietary Xiaomi drivers, and banking applications may require additional manipulations (Magisk, Hide My Applist) to work. Data security when using unverified builds also falls on the shoulders of the user.
- 🔓 Unlocking the bootloader is the first and mandatory step, requiring a Mi Account and 168 hours (7 days) waiting).
- 📲 Installation TWRP — Allows you to create full backups and install third-party ZIP-file.
- 🛡️ Magisk – a tool for obtaining Root rights and hiding system modifications from banking applications.
- 📸 GCam – Installing Google Camera ports will significantly improve photo quality compared to a standard app.
⚠️ Attention: Custom firmware installation resets all data from the device. Be sure to make a full backup of important photos and documents before starting the procedure.

Instructions for manual installation of updates (Recovery Mode)
Even if you don't get an automatic update, you can sometimes find the official firmware of a newer version (like switching from China ROM to Global or upgrading to one version of MIUI) and install it manually, a method called "manual update via Recovery," which is safer than flashing through Fastboot, and doesn't require unlocking the bootloader if you're installing an official firmware in the same region.
To start, you need to download the current ZIP-firmware archive (Recovery ROM) from a proven resource, for example, miui.com or miui.ru. The file should have a.zip extension and weigh about 4-5 GB. After download, rename the file to update.zip and place it in the root of the internal memory of the smartphone (not in the folder, but in the root).
Next, go to the language selection menu (you can use the Update app by clicking on three dots and selecting "Select File", or through Recovery mode: Click Volume Up). + Power with your phone off. From the Recovery menu, select a language, then click "Wipe Data" (only if you navigate between different regions, for example, CN -> Global, otherwise you can skip it, but backup is required. Then select "Install Update" or "Install from storage" and specify the file update.zip.
The sequence of buttons for entering Recovery:
1. Turn off the smartphone.
2. Press the Volume Up (+) button and the Power button.
3. Hold until the Mi logo appears, then release the Meals, leaving the Loudness.
4. Select the language (if not) from the menu -> Wipe Data (optional) -> Reboot.The installation process can take anywhere from 5 to 15 minutes, during which time the phone will reboot several times, it is critical not to remove the battery (which is impossible) and not to interrupt the process, otherwise you can get a brick.
💡
Manual installation Recovery ROM is the only safe way to update the official firmware without loss of warranty and data (subject to installation of the same region).
