How to remove the update on Xiaomi Redmi 9: a step-by-step guide

Many smartphone owners are faced with a situation where Xiaomi Redmi 9 starts to download and install a new version of firmware on their own, often at the wrong time, taking up memory or slowing down the device, and the desire to stop this process is quite natural, especially if the current version of the system is stable and new features are feared.

MIUI is designed to keep users updated on the latest security and interface changes, but the enforcement nature of these actions is sometimes annoying. In this article, we will look at proven ways to help you disable automatic updates to Redmi 9 without obtaining root rights, while maintaining the functionality of the phone’s core functions.

Now, you know, you can't cut the upgrade option out of the system with standard methods, but you can effectively block it from starting. We'll look at the settings inside the menu, working with updater applications, and deeper service management practices. Every step requires care to keep the operating system running smoothly.

Why Redmi 9 is always in need of an update

The main reason for the system’s intrusion lies in Xiaomi’s policy: developers are eager to ensure that security patches are up to date and new MIUI features are introduced. For budget models like the Redmi 9, it’s also a way to optimize the performance of iron through software patches.

Often, users notice that the phone starts downloading files in the background, which is the work of a system process that checks the servers for a new build. If you use Wi-Fi, downloading can begin automatically, unless the appropriate restrictions are set.

• 📱 Automatic check: The system surveys the server several times a day.
• 📶 Wi-Fi download: By default, wireless-only download option is enabled.
• 🔒 Security patches: Critical vulnerabilities force phone to require urgent installation.

Sometimes, an upgrade can lead to unpredictable results on older versions of the hardware, which is why many people prefer to stay on a proven build, and understanding the mechanisms of background services will help you manage your device more efficiently.

Disabling Automatic Boot Through Settings

The easiest and safest way to limit your system appetites is to use the built-in settings, which do not guarantee full lockdown, but significantly reduce the frequency of notifications and prevent heavy files from loading in the background.

To start, you need to go to the settings menu. Find About the phone and click on the logo of the MIUI version. A window will open where the process of searching for updates is usually displayed. Here we are interested in the menu of additional options hidden behind the three dots in the upper right corner of the screen.

In the menu that opens, you need to find the switch that automatically boots, you need to deactivate it, you should also pay attention to the item "Notify us of updates." If you want complete calm, remove the tick here, too, which will prevent annoying banners from appearing.

⚠️ Warning: Disabling notifications does not give 100% guarantee, and the system can still conduct a silent check when connecting to stable Wi-Fi, unless more stringent measures are applied.

When you change the settings, you should restart the device, which will allow you to apply changes in the configuration of system services, and if after a while the phone starts to be active again, you will need a deeper approach to solving the problem.

Stop the system application "Component Update"

A more radical method is to force the system application that is responsible for upgrading to stop and clean up data, often called “Component Update” or simply “Updater” in the MIUI shell, which allows you to reset the accumulated data and temporarily stop the process.

To get to the menu you want, go to Settings → Apps → All apps. You need to find the system process. Sometimes it's hidden, so search by name. When you find the right item, click on it to log into the control menu.

Then you do a sequence of actions: press the Stop button, and then select Clear and Clear everything, which will delete the cached update files and reset the check timers, and then the phone will "think" that it just came out of the box.

• 🛑 Stop: Compulsoryly completes the ongoing verification process.
• 🗑️ Cache Clearing: Deletes temporary download files.
• 🔄 Data reset: Returns the application settings to the factory.

And it's important to note that this is a temporary process, and after a while, the system watchman will start again and resume the check, but if you repeat the procedure regularly, you can keep the system in a static state without any interference.

Using Developer Mode to Block

For advanced users, there is an option to limit background activity through developer mode, which doesn't disable the update directly, but creates an environment where it's harder for the system to persist. We'll limit background processes.

First, activate the hidden menu. Go to Settings → About Phone and quickly click 7-10 times on the MIUI build number. You will be informed that you have become a developer. Then a new option will appear in the “Additional” or “Extended Settings” menu.

Within this menu, find a section related to background processes. The Background Process Limit option allows you to limit the number of applications running simultaneously. Set a limit to "Not More than 1 process" or "No background processes." This can prevent the update service from running in the background.

⚠️ Attention: Excessive restriction of background processes can negatively affect the work of messengers (WhatsApp, Telegram) and mail synchronization.

Also in developer mode, you can find the item "Automatic System Reboot" and make sure it's turned off so the phone doesn't try to reboot spontaneously after a potential quiet patch installation.

Blocking through Connection Settings and DNS

One of the most effective methods is to prevent the phone from connecting to update servers. Because Redmi 9 requires the Internet to download files, breaking that link solves the problem globally, and you can do this through DNS setup or traffic restriction.

In Wi-Fi settings, click on your network name to reveal additional settings. Find IP settings and switch it from DHCP to Static. In the DNS 1 field, enter an address that does not exist or blocks requests, such as 0.0.0.0 or a special ad blocker, if known. However, the easier way is to limit traffic for a particular application.

Go back to the app menu, look for “Component Update,” and go to “Data Use” or “Mobile Internet and Wi-Fi.” You can completely deny the app access to the network. Check “Disable” for both types of connection.

• 🚫 Wi-Fi Blocking: The App Will Not Be Able to Download Files at Home.
• 📵 Mobile Data Blocking: Protecting against In-Time Updates.
• 🔒 Traffic Control: Complete Network Access Ban for Updateer.

This is more reliable than just turning off notifications, and the phone may think it's an update, but it won't be able to download a single byte of information, and it keeps the current firmware version intact.

💡

If you’re using a router that supports DNS configuration (like Keenetic or Mikrotik), add Xiaomi update server domains to the router level’s blacklist.This will block updates for all devices in the house at once.

Resetting network settings as a last resort

Sometimes, errors accumulate in the system and the phone gets stuck in a cycle of constant checks, in which case resetting the network settings may help, not deleting your personal files, photos or contacts, but returning the connection settings to factory values.

Resets can be done via Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Press Reset button at the bottom of the screen. You will need to enter the screen unlock password to confirm the action.

Once rebooted, all stored Wi-Fi passwords will be deleted and mobile access point (APN) settings reset, which can interrupt the suspended update process, as the network configurations the request was through will be destroyed.

It is worth remembering that this is a temporary solution. Once you reconnect to the Internet, the cycle may repeat, so immediately after resetting and connecting to Wi-Fi, it is recommended to recheck the automatic update settings and deny network access for the system application, as described in the previous sections.

⚠️ Warning: Don't confuse Network Settings Reset with Hard Reset, the second option will completely delete all data from the phone, returning it to the state from the store.

The most reliable way is a combination of methods: disabling the autoboot in the menu + denying Internet access for the “Component Update” application in the data usage settings.
