How to permanently remove the “Available Upgrade” notification on Xiaomi Redmi: working methods 2026

The “System Update Available” notification on Xiaomi Redmi smartphones can appear daily even if you deliberately refuse to install a new firmware. The reasons range from the unstable operation of the latest version of MIUI to the banal reluctance to waste traffic or time on a reboot. However, constant reminders are annoying, and the standard click “Remind later” gives a delay of only 24 hours.

In this article, we will discuss 7 Proven ways to disable notifications about updates – from simple (through settings) to radical (using the use of the ADB Separately, we will focus on the hidden risks of ignoring security updates and explain why some methods may stop working after resetting the phone to factory settings. 11 Pro+, Redmi 12 5G, Redmi 10C) on MIUI 12/13/14 HyperOS.

Why does the update notice appear over and over again?

The MIUI reminder mechanism is based on the com.miui.systemAdSolution system service, which is responsible for smart prompts. Unlike regular push notifications, this message is generated at the firmware level, so it cannot be disabled through the Notifications menu in the application settings.

• 🔄 Cyclical timer: After pressing “Remind later”, the system sets a deferred task for the next day.
• 📡 Checking Xiaomi servers: Every 6-12 hours, the phone communicates with update servers (update.miui.com) and downloads a list of available firmware.
• 🛡️ Security Priority: Critical patches (e.g. for vulnerabilities) CVE-2023-XXXX) You can force notifications even if you have disabled automatic checks.
• 📦 Update cache: Downloaded but not installed firmware package (*.zip in folder) /cache) He keeps reminding himself.

Interestingly, on some models (e.g. Redmi Note 10 Pro), the notification is duplicated in the control center (swipe down from the top edge of the screen) as a “System alert”, which is due to the integration of the update service into the MIUI core, which makes it difficult to block it.

Method 1: Disabling Automatic Update Checking

The safest and most obvious method is to prevent the phone from searching for updates on its own, and this will not delete an already downloaded notification, but will stop new ones from appearing.

1. Open the Settings. → The phone.
2. Slip on the item System Update (or MIUI version on old firmware).
3. Press three points (⋮) in the upper right corner and select Settings.
4. Turn off the automatic download slider via Wi-Fi.
5. In the same menu, deactivate Automatic Update Check.

After that, the phone will stop asking Xiaomi servers about new firmware, but the notification already shown will remain in the curtain until manually cleaned.

• 🧹 Swipe left/right on the notification and click “Delete».
• 🔇 Or hold the notification and select “Disable” (on some versions) MIUI).

⚠️ Attention: MIUI 14 and HyperOS, after turning off automatic check, a pop-up may appear with a warning: "Security Updates are recommended." It can be closed, but it will appear once a week.

Method 2: Cleaning the cache and data of the System Update application

If the notification continues to hang even after turning off the automatic check, the problem may be in the cached data of the com.android.updater app.

1. Go to Settings → Applications → Application Management.
2. In the search bar, type “System Update” (or “Updater” in English firmware).
3. Select the app and click Storage.
4. Slip "Clear the cache" and confirm.
5. Then click Clear Data (this will remove downloaded service packs).

After cleaning:

• 🔄 Restart your phone (required!).
• 📵 The notification should disappear. If it doesn't, check the folder. /cache file-like miui_*.zip and manually delete them (you will need a file manager with access to system folders, such as MiXplorer).

Method 3: Block notifications through application settings

In MIUI 12 and later, you can completely prevent the System Update app from showing notifications.

1. Open Settings → Applications → Application Management.
2. Find System Update (or com.android.updater).
3. Go to the Notifications section.
4. Turn off the “Show notifications” slider.
5. For reliability, also deactivate all notification subcategories (e.g., Security Updates, New Features).

This method works on most Redmi models, but there are nuances:

If notifications continue to appear after blocking, try turning off background activity for the System Update app:

1. In the application settings, go to the Battery.
2. Select “Limit background activity”.
3. Also, turn on “Deep Optimization” (if available).

Method 4: Using ADB to disable system service

For advanced users, there's a method using ADB (Android Debug Bridge) that completely disables the system-level update service, which works even if the previous methods didn't work. Importantly, after that, you won't be able to update your phone through the standard menu -- just manually through Recovery or Fastboot.

Instructions:

1. Enable USB debugging in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional settings → For Developers).
2. Connect the phone to the PC and confirm the debugging permission.
3. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell pm disable-user --user 0 com.android.updater


adb shell pm disable-user --user 0 com.miui.systemAdSolution

To get it back, use:

adb shell pm enable com.android.updater


adb shell pm enable com.miui.systemAdSolution

⚠️ Attention: On some firmware (MIUI 14 Global) disabling com.miui.systemAdSolution may cause tiles to disappear in the control center (for example, flashlight or Do Not Disturb mode.

Method 5: Remove the service pack via TWRP (root required)

If you have customized Recovery installed (like TWRP) or root rights installed, you can uninstall the system update application.

• ✅ Notifications will disappear forever.
• ❌ You will not be able to update through OTA (manually through fastboot or TWRP).
• ⚠️ Risk of disrupting other system components (e.g. Mi Cloud).

Instructions for TWRP:

1. Load into the recavator (turn off the phone, then press Power + Volume Up).
2. Go to Advanced → File Manager.
3. Open /system/priv-app/Updater (or /system/app/Updater on older firmware).
4. Delete the Updater folder or the files inside it (such as Updater.apk).
5. Reboot the phone.

For users with Magisk:

1. Install the App Systemizer module from the Magisk repository.
2. In the module settings, find com.android.updater and deactivate it.
3. Reset the device.

💡

Before removing system files through TWRP Make sure to back up the section /system! To do this, select Backup in the main menu of the Recovery → System and save the image to SD-card.

Method 6: Change settings through the parameter editor (for experienced)

V MIUI There are hidden settings that can be changed using applications like Activity Launcher or MIUI Hidden Settings: One of these parameters — auto_update_check_interval, The frequency of updates checks.

How to change it:

1. Install Activity Launcher from Google Play.
2. Open the app and find it in the Settings list (com.android.settings).
3. Slip on “All Activities” and select.settings.SystemSettings.
4. In the menu that opens, find the “Developers” section (if not, turn on the developer mode as described above).
5. Scroll down to “Never Check Update Interval” or “0.”

An alternative method is to use ADB to modify system properties:

adb shell settings put global auto_update_check_interval 0

This will disable automatic verification, but will not delete the notifications already shown. To make them disappear, further clear the cache of the System Update app (see Method 2).

Method 7: Install custom firmware without Xiaomi services

If you're annoyed not only by update notifications, but also by other MIUI features (advertising, restrictions, duplicate applications), consider switching to custom firmware.

• 🌍 LineageOS – pure Android without unnecessary services.
• 🔥 Pixel Experience – firmware with Google Pixel functionality.
• ⚡ ArrowOS – Optimized for Performance.
• 📱 MIUI EU — European MIUI without Chinese services (but with update notifications).

Advantages:

• ✅ No update notifications (unless you manually enable them).
• ✅ More control over the system.
• ✅ Regular security updates from the community.

Disadvantages:

• ❌ Installation difficulty (requires unlocking the loader, TWRP, backup).
• ❌ Possible bugs (e.g., non-functioning) NFC or camera on some models).
• ❌ Loss of warranty (if the phone is under warranty).

For custom firmware installation instructions, look for XDA Developers or 4PDA forums for your Redmi model. For example, for the Redmi Note 11 Pro+ 5G, the topic is LineageOS 20 on XDA.

💡

Custom firmware requires unlocking the bootloader, which resets the phone to factory settings and erases all data. Always back up before experimenting!

Risks of Ignoring System Updates

Before disabling update notifications, it is worth assessing potential threats:

1. Security vulnerabilities: Older versions of MIUI may contain unpatched vulnerabilities (e.g., CVE-2023-2129 in MIUI 12.5, which allows bypassing screen locks) that can be used by attackers to steal data or install malware.
2. Application incompatibility: New versions of Google Play Services or banking applications (such as SberBank Online) may require fresh firmware.
3. Bugs and Lags: Older versions of MIUI often have problems with battery, overheating, or camera performance (e.g., the Redmi Note 10 Pro on MIUI 12.0.8 had a camera zoom bug).
4. Blocking Features: Some features (such as Mi Share or Game Turbo) may stop working without updates.

If you still decide to stay on the old firmware, follow these recommendations:

• 🔒 Install a reliable antivirus (e.g. Bitdefender or Kaspersky).
• 📵 Disable the installation of applications from unknown sources.
• 🔄 Check for critical security updates manually regularly (e.g., at Xiaomi Security Center).
