Owners of the legendary Xiaomi Redmi 4 (Prada) often face a situation where the device no longer receives automatic notifications about the release of new versions of the operating system. This is a legitimate concern, as security and new features become unavailable, the problem can be hidden in software failures of the MIUI shell itself, and in hardware restrictions or changes on the side of the servers of the manufacturer.
In most cases, the lack of updates does not mean that the phone is faulty. Often the reason is that the device has already received the latest version of the software available for it, or the firmware region does not coincide with the region of the update server. It is important to understand that Redmi 4 is a model released several years ago, and the official support cycle for it is already completed or is coming to an end.
If you are used to relying on automatic OTA-Over-The-Air can be confusing if it suddenly disappears, but there are many ways to check for updates manually or even install a more recent version of the system than the standard menu offers.
Official Support Status and End of Update Cycle
The first thing that the owner of Xiaomi Redmi 4 needs to understand is the natural life cycle of the device. Xiaomi smartphones, especially budget and mid-range, receive guaranteed support for a certain period, usually 2-3 years from the date of release.
For Redmi 4, the last stable version is often MIUI 9 or MIUI 10 based on Android 6.0 or 7.0, depending on the processor modification (Snapdragon 425 or 430).If your phone shows that the system is updated to the latest version, but you see information on MIUI 11 or 12 on the Internet, this does not mean an error. This means that for your particular model (codename: prada) there are no further official releases planned.
There is also the concept of "beta testing," which is available to enthusiasts, but it doesn't apply to older devices: Update servers simply stop sending data packets to devices whose Identification Number (IMEI) or model is no longer on the supported list.
⚠️ Warning: Attempts to force the phone to upgrade to a version of Android that isn’t designed for its hardware (e.g. Android 10 or 11 on Redmi 4) can cause the device to be completely inoperable.

Redmi 4 official support is complete, so no new ones are available. OTA-The notification is the normal behavior of the system, not an error.
Problems with the firmware region and Xiaomi servers
A common reason for the lack of updates is the discrepancy between the region of the installed firmware and the region in which the device is located. Global ROMs receive updates on a separate schedule, different from the Chinese ROM or Indian versions. If you bought the phone in China and use it in Europe with global firmware, the server can block the direct update.
Xiaomi servers also sometimes experience overloads or technical work, and at such times, a request from your Redmi 4 may not receive a response, and it is worth considering that some carriers block automatic updates if they believe that the new version of the software may conflict with their network settings.
Check if the region has changed in the system settings. Sometimes, after resetting or flashing, the region may be set incorrectly, which confuses the algorithm for finding updates. To work correctly, you need to select your real country of residence in the settings (Settings → Advanced Settings → Region).
- 🌍 Global firmware: Updated less frequently, but more stable and has Russian out of the box.
- 🇨🇳 Chinese firmware: Gets updates first, but often does not have Google services and Russian without additional manipulations.
- 📶 Operator Blocking: Some carriers may delay the release of updates for testing in their networks.
Lack of free memory to load the packet
One of the most common but often overlooked reasons why the Xiaomi Redmi 4 isn’t being updated is the basic lack of free space in internal storage. Update files can weigh between 500MB and 2GB, and the system requires extra space to unpack and install them. If memory is crammed with photos, app cache or heavy games, the download process simply won’t start.
Android requires a buffer zone to function properly. When the free space is less than 10-15% of the total, the update engine can automatically pause to keep the phone running smoothly. You may notice that the Download button is either inactive or nothing happens after pressing.
It is recommended to clean up the storage of unnecessary files before trying to update it. Particular attention should be paid to the Download folder and the messenger cache (Telegram, WhatsApp), which can take up gigabytes of space. Once you free up space, be sure to restart the device so that system services correctly recognize the changed amount of free memory.
💡
Use the built-in Security → Cleanup app to quickly clear up space before upgrading your system.
Conflicts after obtaining Root rights and system modification
If you have previously received superuser rights (Root) or installed custom recavators (for example, TWRP), the official update mechanism Xiaomi (OTA) will stop working. This is a security mechanism: the system checks the integrity of the system partition, and if you detect modifications, blocks the installation of updates to avoid conflicts and “bricking” the device.
Having a modified bootloader can also affect this process, although in some cases updates do come but require manual installation confirmation. However, if system files have been changed (removed standard applications, modified build.prop), the digital signature verification will not pass, and you will receive an error message.
To get the updates back, you need to get the phone back to its original state, which means locking the bootloader and installing the stock firmware through Fastboot mode with full data cleaning, and as long as the device is modified, you don't need to count on automatic updates.
⚠️ Warning: Attempting to install an official update on a modified system without pre-cleaning can result in a cyclic reboot (bootloop).
How to check for Root-Rights?
Manually check and install updates through the menu
Even if the automatic notification does not arrive, you can initiate a search for the new version yourself. To do this, go to the settings menu and select About Phone. At the top of the screen, the current version of MIUI is usually displayed. Click on this number or the three-dot menu icon in the upper right corner.
In the menu that opens, select Check Updates, the system will contact the server and, if there is a current version for your model and region, prompt you to download it, and if you see a message "No Updates", this may mean that you are already on the latest version or the server is temporarily unavailable.
Sometimes it helps to change the way you check, and in the version selection menu (three dots), you can try to switch between the modes "Stable version" and "Beta version" (if available), although for older models like Redmi 4 beta tests are already closed, you can also try to change the region in the phone settings to "India" or "Global", check the updates, and then return your region.
☑️ Checklist before manual update
Installation of firmware manually through Recovery Mode
If the automatic method does not work, the most reliable method is to manually install the update archive. You will need to download the firmware file (.zip format) strictly for your model (Redmi 4 / prada) from the official website or proven resources.
Once you download the file, place it at the root of the phone's internal memory. Then go to the update menu (as described in the previous section), click on three dots and select Select the firmware file. Find the downloaded archive and confirm the installation. The phone will restart and begin the update process.
This method bypasses many network and regional binding errors, but it requires care: if you download firmware for another model (like the Redmi 4X or 4A), you run the risk of getting a non-functioning device. Always check the code name of the model.
| Parameter | Automatic (OTA) | Manual (Recovery) |
|---|---|---|
| Difficulty | Low. | Medium |
| Risk of error | Minimum | Medium (requires the correct file) |
| Data retention | Yes. | Yes (when choosing Update) |
| Network requirement | I'll be sure. | Only for downloading the file |
⚠️ Note: When manually installed, make sure the file has the.zip extension and is not unpacked.The archive should be in the root folder, not in the subfolders.
Use of Mi Flash Tool and Fastboot Mode
For advanced users who want to clean up the system completely or switch from one firmware version to another (for example, from China to Global), there is a method of firmware through a computer. This uses the Mi Flash Tool utility and Fastboot mode. This method allows you to install any compatible version of the software, ignoring the limitations of OTA.
You'll need to download the firmware image in.tgz (Fastboot ROM), unpack it, and run the Mi Flash Tool on a Windows PC. The phone goes to Fastboot mode. The computer will identify the device, and you can select Clear all mode and start the process.
It is a "nuclear" method of solving problems with updates, it is guaranteed to eliminate software errors, viruses and conflicts, but using this method requires an unlocked bootloader, the procedure of obtaining which takes from 3 to 7 days of waiting through the official Xiaomi website.

fastboot rebootThis command is an example of interaction with the device in Fastboot mode, although the Mi Flash Tool graphical interface is usually used for full firmware. Be careful when choosing a cleaning mode: the "Clean all and lock" option will block the bootloader, which can be problematic if you are flashing a region other than the original one.
