How to remove the update on Xiaomi: a complete guide to rollback system

Users of Xiaomi and Redmi smartphones often face a situation where automatic updating of the MIUI system or the new HyperOS shell brings more problems than benefits. The device can start to work slower, discharge faster or new versions of the firmware may disappear familiar features. There is a natural desire to return everything as it was, but standard means of the menu “About the phone” to do this is impossible.

The process of removing an already installed version of the Android or shell is not a standard feature provided by the developers. Full rollback of the system to an earlier version is possible only through a complete data reset or flashing of the device, this is due to the security architecture of modern mobile operating systems, which do not allow you to simply “delete” update files, leaving the system working.

In this guide, we will look at all the available methods of solving the problem, from cleaning the update cache to a complex rollback through Recovery. You will learn how to prevent the automatic installation of an unwanted package and the risks of forced modification of the software version.

Why you can’t just remove the update in your settings

Many users mistakenly believe that the "Delete Last Update" button is hidden in the back of the system settings, but the logic of Android and MIUI is different. When you get a notification of a new version, the system downloads the firmware archive to a hidden partition of memory. Until you reboot and install it, it's just a set of files.

Once the phone has restarted and made changes, the old version is replaced by a new one, at which point the old OS files are permanently erased, and the downgrade is officially blocked by the manufacturer to ensure the security of user data and prevent vulnerabilities.

There are several scenarios that require intervention:

• 📉 Unstable work: after the update, bugs, application departures or overheating appeared.
• 🔋 Battery problems: Autonomy has fallen due to optimization of the new version for other models.
• 🚫 Blocking functions: in the new version removed the ability to install third-party themes or changed the interface.
• 📦 Memory Filling: The service pack takes several gigabytes and interferes with work.

⚠️ Warning: Attempting to interrupt the installation process or tamper with system files while booting can cause the device to “fill up”. If the phone has already been updated, the only safe way back is to completely reset or flash it.

Remove a downloaded but not installed package

If the update has only downloaded in the background, but the phone hasn't yet offered a reboot for installation, or you've put it off yourself, the files take up space in memory, in which case they can be safely deleted, freeing up space. This is not a system rollback, but solves the memory problem.

To access system files, you need permissions to access hidden folders. A standard file manager may not display system partitions without enabling a special mode. You need to activate the display of hidden files in the Explorer settings.

The sequence of actions to clean the update cache:

1. Open the File Manager application.
2. Go to the application settings and turn on Show hidden files.
3. Go back to the root directory and find the folder. downloaded_rom.
4. Inside, you'll see an archive with the.zip extension. This is the service pack.
5. Delete this file. Also check the MIUI folder at the root of the internal memory for similar archives.

Once the file is deleted, the system will stop offering to install that particular version. However, if automatic updates are enabled, after a while the phone may download the package again.

Disabling automatic system updates

To avoid re-downloading unwanted software, it is recommended to block the system updater’s access to the Internet.This does not remove the already installed update, but prevents it from appearing in the future if you reset your phone or decide to stay on the current version.

The most effective way is to use a developer menu or special applications, but the most reliable way is to limit traffic for the system application.

Blocking actions:

• 🚫 Through Traffic Settings: Go to Settings → Annexes → All applications → Updating components → Traffic: Turn off Wi-Fi and mobile data transmission.
• 🛑 Through ADB (For advanced: Connect your phone to your PC and type a command to freeze the service pack. ADB-computer-driver.
• 🔒 Blocking through hosts: For root-right users, you can block update server domains in the hosts file.

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

This command in the ADB console completely disables the standard update module. Be careful: after that, you can't even get critical security patches manually through the phone's menu.

💡

Before blocking system applications, back up your contacts and photos. An error in the ADB command can lead to unstable system operation.

Full data reset (Hard Reset) as a way to roll back settings

If the update is already installed and causes crashes, often the problem is not the firmware itself, but the conflict of the old settings with the new code, in which case a full reset to the factory settings helps, it will not return the old version of Android, but will clean the system of garbage.

Before starting the procedure, make sure that the battery is at least 60% charged, the formatting process takes time, and a sudden power outage can damage memory parts, save all important data to the computer or to the cloud, as the internal memory will be completely cleared.

Instructions for resetting via menu:

1. Go to Settings. → The phone.
2. Click on the MIUI or HyperOS version several times to activate additional options (if required).
3. Click on the menu (three dots) in the top corner and select Erase all data.
4. Confirm the action with the unlock code or account password.

An alternative method through Recovery Mode is useful if the phone does not load normally. To log in, press both the Volume+ and Power buttons on the phone turned off. From the Recovery menu, select Wipe Data → Wipe All Data.

⚠️ Warning: Once reset, the phone will require you to enter a password from a Google account or Mi Account that was previously synced (FRP). Make sure you remember the entry data.

Reverse the firmware to an earlier version (Downgrade)

This is the most radical and complex method to actually remove a new update and return the old version of the system. Xiaomi officially prohibits rollback protection, but in some cases this is possible through Fastboot mode and the Mi Flash Tool program.

The most important limitation is that you can't just flash a version of Android below the one you're currently using if you're using protection. However, if you're switching from global to Chinese (or vice versa) or using special methods to unlock the bootloader, you can roll back. The bootloader must be unlocked.

Main stages of the procedure:

• 💻 PC Preparation: Install drivers ADB Fastboot and Mi Flash Tool.
• 📥 Firmware search: Find on the official website of Xiaomi firmware archive (Fastboot version) exactly the version to which you want to return.
• 🔓 Unlock: Make sure the bootloader is unlocked through the Mi Unlock service.
• 🔄 Firmware: Transfer the phone to Fastboot mode (clamping Volume and Power), connect to the PC and run the firmware in the Mi Flash Tool, selecting Clean All mode.

The stitching process takes 5 to 15 minutes, and it is strictly forbidden to turn off the USB cable at this time, and if the process is interrupted, the phone can turn into a brick that requires programmatic repair in the service center.

💡

The firmware rollback is only possible when the bootloader is unlocked and the official Fastboot firmware is available in the desired version. You can't just "remove" the update with a button.

Frequent questions and problems when removing updates

Users often ask questions about the security and consequences of system software manipulation, and the following are answers to the most common of them, based on the experience of using Xiaomi and Poco devices.

Manipulation of smartphone software requires carefulness and understanding of the risks.Always weigh the need to return the old version: often problems are solved by simply resetting the settings or waiting for the next patch to fix the bugs.
