Owners of the legendary Xiaomi Redmi Note 4 smartphone (codename nikel) often wonder about the feasibility and security of updating the system. Despite the fact that official support for the model has been discontinued, the development community continues to release current builds based on MIUI 11 and MIUI 12. Finding an answer to the question of which latest firmware for the Xiaomi Redmi Note 4 is stable requires understanding the differences between global (Global), European (EEA) and Chinese versions of the software.
The relevance of the software directly affects the security of your data and compatibility with new versions of applications. Many users mistakenly believe that the release of Android 10 or 11 for this model is impossible, but custom firmware allows you to go beyond the limitations of the system. MIUI 9 It is important to distinguish between official OTA-Updates that come “over the air” and manual installation of recovery archives.
In this article, we will take a closer look at the current device support status, look at the technical specifications of the latest builds, and provide a step-by-step algorithm for a secure update, learn why it is sometimes worth staying on the old version and how to properly check your current build before starting any manipulation of system files.
Official Support Status and Final Versions of MIUI
The official support for the Xiaomi Redmi Note 4 smartphone from the manufacturer was completed several years ago.The final stable version released for the global market (Global) was MIUI 10, based on Android 7.0 Nougat. However, for the Chinese version of the device (CN) and the European region (EEA), there were updates to MIUI 11 and even test builds of MIUI 12, which creates confusion among users.
Development of official updates has stopped, meaning no security patches for vulnerabilities discovered after 2019.However, update servers continue to work, allowing devices to check for packets. If you own a global version, chances are the last update available will be V10.2.3.0.NBBMIXM or V10.2.4.0, depending on the regional anchorage.
⚠️ Warning: Attempting to install Chinese firmware on a global device (or vice versa) without unlocking the bootloader will result in the device being locked (Bootloop).
For enthusiasts looking to get a fresher Android, the only option is to install customized recavators like TWRP and then firmware alternative operating systems.The official upgrade path is closed, and MIUI servers will no longer offer new versions for this model through the settings menu.
Technical characteristics of current assemblies
The latest builds available for the Redmi Note 4 vary significantly in volume and optimization. While the early versions of MIUI 8 were lightweight, the final releases of MIUI 10 and 11 required more Snapdragon 625 processor resources.
The table format below shows the main differences between the latest stable versions available for different regions, which will help you identify your current build and understand whether the update makes sense.
| MIUI version | Android version | Size of OTA (MB) | Region |
|---|---|---|---|
| MIUI 10 (V10.2.3.0) | Android 7.0 | ~450MB | Global |
| MIUI 11 (V11.0.3.0) | Android 7.0 | ~520MB | China (CN) |
| MIUI 12 (Beta) | Android 7.0 | ~1.2 GB | Global (Dev) |
| MIUI 10 (V10.2.4.0) | Android 7.0 | ~460MB | Europe (EEA) |
Note that the size of the update file does not always correlate with the number of new features. Often the package includes fixes for critical security errors or updates to basic modem files that improve communication quality. Redmi Note 4 is characterized by high stability even on older versions of the software, so chasing the version number does not always make sense.

How to check and download the latest version
Checking for updates is a standard procedure that can be done directly through the smartphone interface. However, if an automatic update doesn't come, it doesn't always mean you're on the latest version.
To manually check, you need to go to your device's settings menu. Navigation on the menu may vary slightly depending on the version of MIUI, but the overall path remains unchanged.
- Open the Settings app.
- Select the item About phone (About phone).
- Tap the block with the MIUI version (large digit in the center of the screen).
- Click the Check for Updates button.
If the system says there are no updates, but you know about the release of a new version, you can use the manual file selection function. To do this, click on the three dots in the upper right corner of the screen and select Select a firmware file. You will need to pre-download the Recovery ROM archive (.zip) and place it in the root of internal memory.
💡
Use only official sources or trusted forums (XDA, 4PDA) to download firmware. Files from unverified blogs may contain malicious code.
Manual update instructions via Recovery
Manual updates are the most reliable way to install the latest firmware for Xiaomi Redmi Note 4, especially if it is automatic. OTA-This method allows you to "flash" the system partition clean, eliminating accumulated errors and cache of old versions.
Before starting the procedure, make sure that the battery is at least 60% charged, interrupting the process of writing data to flash memory can damage the boot sector, and it is also recommended to back up important contacts and photos.
☑️ Firmware preparation
The installation process is as follows:
- 📂 Download the current firmware archive (Recovery) ROM) for your model.
- 📝 Rename the downloaded file to update.zip (Make sure that the extension is.zip, not.zip.zip.zip).
- 📲 Move the file to the root folder of the phone’s internal memory (not to the folder with photos or documents).
- ⚙️ Go to Settings. → The phone. → Version. MIUI.
- 👆 Press the menu (three dots) → Select a firmware file and specify your archive.
- ✅ Confirm the action and wait for the reboot.
⚠️ Note: If after selecting a file, the phone simply restarts without starting installation, then the version in the archive is older or equal to the current one, or the file is damaged.
Problems in updating and their solution
The Redmi Note 4 update process doesn’t always go smoothly, and the most common problem is a file verification error or an endless bootloop, which can be caused by a conflict of modified system files, the presence of Root rights, or damage to the bootloader.
If you encounter a “brick” (the phone hangs on the MI or Android logo), try to enter Recovery mode. To do this, press the Volume Up and Power buttons simultaneously. From the Recovery menu (Chinese or English), select Wipe Data (data reset). This will delete all user data, but often allows the system to start.
In more complex cases, when Recovery does not help, you will need to use a computer and the Mi Flash Tool for firmware in Fastboot mode. ADB/Fastboot PC-only.
💡
Resetting user data (Wipe Data) solves 90% of the problems with cyclic reboot after the update, but requires a backup.
Castom firmware: is it worth moving?
Since the official support for Xiaomi Redmi Note 4 ended on Android 7.0, many users are considering installing custom firmware (LineageOS, Pixel Experience, Xiaomi.eu), which allows you to get Android 10, 11 and even 12, as well as fresh security patches.
But switching to caste has its own risks: the camera may perform worse because of the lack of original drivers, and some banking applications may fail without additional configuration (MagiskHide), the stability of such systems depends solely on the enthusiasm of the particular developer.
If you are not ready to spend time debugging bugs and finding working versions of Google Pay, it is better to stay on the latest official MIUI 10/11. For everyday tasks (calls, messengers, YouTube), the capabilities of the stock system are quite enough, and stability is higher than that of experimental builds.
