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

Modern Xiaomi smartphones running on the shell of MIUI or the new HyperOS often receive automatic updates that are designed to improve security and add new features. However, in practice, users often face a situation when after installing a new version of the firmware, the device starts to run slower, discharge faster or errors appear in the interface, in which there is an urgent need to return the system to a previous, more stable state.

The process of removing an already installed update is not a standard function that can be performed with a single button in the settings menu. Android does not provide a simple mechanism to “remove the latest update” through the standard interface, as this affects system memory partitions. However, there are proven methods to roll back the software version or clear the space occupied by installation files if the installation has not already been done.

In this article, we will take a look at all the available solutions, from simply cleaning the bootloader cache to completely flashing the device with your computer. It is important to understand that rolling back to an older version of the firmware (Downgrade) often requires unlocking the bootloader, which can lead to a loss of warranty. We will look at safe ways and warn about the risks so that you can make an informed decision.

Why You May Need to Remove an Update

Users often wonder if they should remove a new update if it is already installed, and the main reasons for such actions are critical bugs that developers did not notice during the testing process, for example, a new version of MIUI can cause conflicts with certain applications, disrupt communication modules, or lead to unpredictable interface behavior.

Another common problem is optimizing power consumption, which sometimes starts to run out within hours of an upgrade, even in downtime, which can be due to errors in the management of background processes or incorrect drivers in a new build, in which cases, returning to the previous version often solves the problem of autonomy.

⚠️ Warning: Before any manipulation of system files, be sure to back up important data. The rollback or flashing process can result in the complete removal of all information from the internal drive.

Also, it can be custom modification incompatible, because if you've used root rights or system tweaks, the update can block them or cause a "cyclical reboot," in which case removing the update is the only way to get your phone back to working without going to the service center.

• 📉 A sharp drop in performance and the appearance of lags in the interface.
• 🔋 Increased battery consumption and overheating of the body in simple.
• 📡 Problems with Wi-Fi, Bluetooth or mobile network.
• 🐛 Emergence of critical system application errors.

It is worth noting that not all problems are solved by rollback. Sometimes unstable work is caused by hardware defects that simply coincided with the update, so before starting active actions, it is recommended to analyze the situation and read the feedback of other owners of your model on profile forums.

Cleaning up the downloaded update file

If the update has only downloaded to the phone but hasn’t been installed yet, it can be easily deleted, freeing up space in memory. Updates take up a significant amount of space, usually 2 to 4 GB, and are stored in hidden system folders.

Most often, Xiaomi Update Installer saves packages in the directory downloaded_rom. To find and delete this file, you need to go to the Explorer menu and enable the display of hidden files. This action will allow you to see the system folders, which are usually hidden from the user's eyes to prevent the accidental deletion of important data.

Once you find a file with the.zip extension, you can delete it safely. This action will not affect the current operation of the system, but will prevent you from automatically installing the update when you restart or at night if this feature is activated in the settings.

💡

To prevent the update from downloading again automatically, go to the Software Update Settings, click on three dots in the corner and select “Delete Service Pack” or disable auto-update.

In some cases, the file can be protected from deletion in the usual way, then you should try to clear the data of the Update application itself. To do this, go to Settings → Apps → All Apps → System Update → Memory → Clear the data. This will reset the status of the Update bootloader.

Recovery Mode (without PC)

The official way to roll back to an earlier version of firmware via the Recovery menu is not available on all devices, but it is worth trying it first.This method only works if you are trying to roll back to the version that was installed earlier, and only within one type of firmware (for example, from global to global, but older).

First, you need to download the desired firmware version in.zip format for your device. The file should be renamed to update.zip and placed in the root of internal memory. After that, the phone turns off, and you enter Recovery mode by pressing the Volume up + Power key combination.

The Recovery menu selects the language (if available) and the option "Install update.zip." If the system allows rollback, the process will begin automatically. However, most often MIUI blocks the installation of the older version, giving an error "Can't verify update." This is a downgrade protection that can not be circumvented without an unlocked bootloader.

If you see a message that you can't verify, it means that without unlocking the bootloader and using the computer, this method will not work. Do not try to use third-party patches to bypass the check in Recovery, if you do not have experience, as this can damage the boot sector.

Complete Fastboot Fastboot Fastboot Fastboot

The most reliable way to remove the current update and return the phone to the previous version is to completely reflash through Fastboot mode, USB-This method allows you to install any version of the firmware, even the older one, but it completely erases all data.

The first step is to unlock the bootloader. Without this step, you can't install the old firmware. The unlock process takes 7 to 168 hours (depending on the region and status of the Mi Account) and requires you to apply through the official Mi Unlock app. Once successfully unlocked, the phone is ready to accept any version of the software.

The firmware process is as follows: the phone is transferred to Fastboot mode (clamp Volume down + Power), connects to the PC, the program selects the downloaded image and the “Clean All” mode. After starting the process, the new data will start writing to the phone memory.

⚠️ Note: Using Clear All and Lock mode when running a regional firmware (e.g., Chinese firmware on a global device) can result in a device being locked (Hard Brick».

Once the process is complete, the phone will automatically restart. The first boot can last up to 10-15 minutes as the system performs application optimization, resulting in a clean system with the version of Android and MIUI you chose to install, effectively removing the problematic update.

Resetting settings as an alternative

Sometimes the problem is not the update code itself, but the conflict between the old settings and the cache with the new version of the system, in which case full firmware may be unnecessary, and it is enough to perform a full reset (Hard Reset), which will return the system settings to factory parameters, eliminating software conflicts.

You can reset via the phone’s settings menu: Settings → About Phone → Reset → Erase all data. Alternatively, you can use the Recovery menu as described above by selecting Wipe Data.

Once reset, the phone will behave like a new one, and often after this procedure, the lags and battery problems that appeared after the upgrade disappear, and if that didn't work, then the problem lies deeper, in the firmware version itself, and it is downgrade that is required.

• 🗑️ Remove all user data and settings.
• ⚙️ Returns system parameters to factory values.
• 🚀 Can resolve software conflicts after update.
• 🔄 Does not change the Android version or MIUI older.

It is recommended to reset after each major update to the Android version (for example, the transition from 12 to 13) to ensure stable operation of the system.

💡

The safest way to fix problems after an update is to completely reset your settings. If that doesn't work, you need a complicated flashing procedure to unlock the bootloader.
