Why Xiaomi Redmi Note 9 is not updated: full review

Owners of popular smartphones often face a situation where the long-awaited notification of a new version of the system does not appear, especially for the Xiaomi Redmi Note 9 model, which, despite its popularity, has a clearly limited support life cycle.

In this article, we will take a closer look at the technical and political reasons why your Redmi Note 9 might ignore upgrade requests, learn about the differences between the global and Chinese firmware versions, learn how to test the relevance of the software yourself, and whether to switch to custom builds.

Official support policy and timing of updates

Xiaomi has a specific strategy for releasing updates for its devices, which directly depends on the price segment and the year of the model. Redmi Note 9, released in 2020, was originally positioned as a budget hit, which imposes restrictions on the duration of software support compared to the flagship series Mi or Xiaomi.

Normally, the company’s budget and mid-budget smartphones receive two major operating system updates and three years of security patches. For the Redmi Note 9, the main cycle was the MIUI shell based on Android 10, followed by the transition to Android 11 and Android 12. After the release of MIUI 14 (based on Android 12/13), official support for the main versions of Android for this model was virtually completed.

⚠️ Note: If your smartphone is stable MIUI 12 or 13, no upgrade to newer versions MIUI 14 or HyperOS is a regular situation, not a device malfunction.

It is important to understand that stopping major updates does not mean complete abandonment of the device. Security patches that close critical vulnerabilities may occasionally be released, but their occurrence is becoming more rare and irregular. Update servers gradually stop sending data packets to devices whose life cycle has come to an end.

Technical reasons for the lack of notifications on the device

Even if support is not officially finished, users may not see the updates due to a number of technical nuances. Often the problem lies in the region chosen when you first set up your smartphone. Regional settings affect which server the device receives data from, and the speed of firmware distribution in different countries can vary significantly.

Another common reason is the presence of a modified firmware or unlocked bootloader. 9 custom-made_recovery_ or changed system files, mechanism OTA (Over-The-Air updates stop working correctly, the system checks the integrity of files, and if there are inconsistencies, blocks the installation of official packages.

Also consider the cumulative nature of the update errors: if you missed several intermediate versions, a direct transition to the last available version may not be possible. In such cases, the update algorithm requires the serial installation of all missed packets, which takes a lot of time and space in the internal storage.

💡

Try manually changing your region in settings (like India or Singapore), checking for updates, and then returning your region back.This often encourages the server to send a service pack.

Differences between firmware versions: Global, EU and China

Understanding the differences between firmware versions is critical for Xiaomi owners. The Global ROM is designed for the international market, stable, but it comes later than the Chinese version (China ROM) gets the innovations first, but lacks many Google services and contains a lot of Chinese software that is difficult to remove.

The European version (EU ROM) is often created by enthusiasts or regional distributors.It may contain features cut from the global version, but its installation requires unlocking the bootloader.Using unofficial builds or firmware designed for other regions is one of the main reasons why the Redmi Note 9 stops seeing official updates.

The following is a table showing the main differences in the approaches to updates for different regions:

If you purchased a device designed for the Chinese market and reflashed it to a global version without officially changing your ID, Xiaomi servers can block receiving updates, a security mechanism that prevents the use of unlicensed software.

How to Check and Install Update Manually

If the automatic search doesn't work, you can try to force the process to start, go to the settings menu and select About phone, and in the window that opens, you need to click on the MIUI version (square with the logo) several times to activate the hidden menu, and select the option to select the firmware file.

The.zip update file must be downloaded from the official website or proven resources and placed in the root folder of internal memory. It is important that the file is designed specifically for your model and region. Incorrect firmware can lead to data loss or software failures.

Once the file is selected, the system will check its integrity, and if the file is successfully verified, the installation process will begin, which can take 5 to 15 minutes, during which time the smartphone will be rebooted several times, and do not interrupt the process or turn off the device even if the screen goes out.

⚠️ Warning: Manually installing firmware through the file selection menu only works if you upgrade to a newer version of the same regional build. Transitioning from Global to China or vice versa is impossible without completely cleaning the data and unlocking the bootloader.

MIUI server problems and network settings

Sometimes the reason is not the smartphone itself, but rather the server-side problems. MIUI servers can experience overload, especially during the release of major updates for new flagships. At such moments, requests from older models such as the Redmi Note 9 can simply be ignored or lost in line.

The process is also affected by the quality of the Internet connection and settings. DNS. Use of non-standard DNS-servers (e.g. from Google or Cloudflare) can speed up connection to update servers if the provider blocks or slows down traffic. 4G/5G, so IP-Mobile carrier addresses sometimes have less ping to Xiaomi servers.

Time is also important, because updates often come in waves, and even if a friend of yours with the same phone has already received an update, it doesn't guarantee that you'll get it right away, and it gradually increases the reach of users to minimize the number of bug complaints if critical bugs are detected.

Alternative Ways: Custom Firmware and Risks

For users who want to get a more recent version of Android on the Redmi Note 9 after the end of official support, custom firmware remains. Popular builds such as LineageOS, Pixel Experience or Xiaomi.eu allow you to install Android 13, 14 or even later.

The main obstacle is the need to unlock the bootloader (Unlock Bootloader). The official procedure through the MI Unlock tool requires an account to be linked to the device and waits from 7 to 30 days. Once unlocked, the warranty on the device (if it was still valid) burns down, and the data is completely deleted.

Installation of custom software carries risks:

• 🔒 Possible loss of access to banking applications due to breach of security integrity.
• 📉 The camera may perform worse than on stock firmware due to the lack of original processing algorithms.
• 🔋 Battery life can change for the worse or better depending on optimization.

💡

Switching to custom firmware is the only way to get fresh Android on the Redmi Note 9, but it requires unlocking the bootloader and carries the risk of losing warranty and stability.

If you're not ready to experiment, it's best to stay on the latest official stable version, which provides the balance between performance and safety that engineers put in place when designing the Redmi Note 9.
