How to undo the latest updates to Android Xiaomi

The situation when after automatically loading a new version of the operating system, the smartphone begins to work unstable, is familiar to many owners of Xiaomi equipment. Sudden battery discharges, overheating of the case or the disappearance of familiar functions can be an unpleasant surprise after a planned update.

The rollback process is not a standard feature in the settings menu, so it requires certain technical manipulations. Unreplacement involves completely reinstalling the earlier firmware version on top of the current one, which often involves deleting all user data. Understanding the risks and properly preparing the gadget are key success factors in this procedure.

In this guide, we will discuss in detail all the available ways to return to the old build MIUI or HyperOS. You will learn about methods using and without a computer, and understand when the procedure is impossible due to locking the bootloader.

Why is it necessary to roll back the system?

Electronics manufacturers regularly release security patches and new versions of shells in an effort to improve functionality. However, optimization sometimes suffers in the pursuit of new features, which is especially noticeable in models of the past. Users often find that Android begins to consume more power after an update or interface artifacts appear.

One of the main reasons for the return is loss of performance: heavy graphics effects of the new shell may not work properly on the old hardware of the processor, and there are cases when banking applications cease to function properly due to changes in SELinux security levels or certificates.

⚠️ Note: Reverse the firmware version to earlier (Downgrade) on devices with unlocked bootloader can lead to complete data loss without the possibility of recovery, if you do not make a backup copy.

Another factor is regional specificity: the global version of firmware may lose features that were available in the Chinese build, or vice versa, add unnecessary software, in which enthusiasts prefer to return to a proven version where everything worked stable and predictable.

Preparation of the device for the rollback procedure

Before you start any action with system files, you need to complete a number of preparatory steps. Ignoring this stage can lead to the fact that you lose important contacts, photos and correspondence forever. Backup is the first and most important step.

Make sure the battery is at least 60-70%, the flashing process is energy intensive, and suddenly turning off the device at a critical time of writing system partitions can disrupt the structure of the file system.

You also need to download the firmware file you plan to install_build_, You can find current and archived assemblies on official forums or specialized resource aggregators. The file should be in.zip format for the method through Recovery or.tgz for the method through Fastboot.

Recovery Menu Recovery Method (without PC)

This is the easiest way to do this, and it doesn't require a computer, but it's a significant limitation: Officially, you can only upgrade to a newer version through the Recovery menu or reinstall the current one. To install an older build, you usually need an unlocked bootloader and use special scripts or tools inside Recovery mode.

First, you need to put the downloaded firmware archive in the root of the device's internal memory. Don't pack the file into extra folders, it needs to be directly at the root so the system can find it. Rename the file to update.zip if the instruction for a particular method requires it, although modern versions of MIUI often recognize the original name.

Then you go to Recovery mode. To do this, turn off your smartphone completely, and then press the combination of the buttons Volume Up + Power. Hold them until the Mi logo appears, then release the power button, continuing to keep the volume. In the menu that appears, select the language (usually English or Chinese) by touching the screen.

If the bootloader is unlocked, you can try to select Install update.zip (or similar). The system will check the integrity of the file. If the version is older than the current one, the standard installer will give an error, in which case users often resort to third-party Recovery, such as TWRP, which allows you to ignore the version verification and force the archive to be installed.

💡

If standard Recovery does not allow you to install a file, try renaming the firmware archive to «update.zip» And put it in a folder «downloaded_rom» at the root of the memory, then select “Select the update package” (three dots in the corner).

Recoil through Fastboot mode using PC

The most reliable and common method of rollback is using Fastboot mode and the computer, which allows you to drink all the parts of the system clean, which ensures that there is no conflict between the old and new files. You will need a USB cable, a Windows PC and the Mi Flash Tool utility to work.

First, you need to put your smartphone in Fastboot mode. Turn off the device and press the Volume Down buttons at the same time. + Food, and you'll see a picture of a hare in a hat, a squirrel, repairing an android, or a sign that says, FASTBOOT. Connect your phone to your computer through USB-port.

On your computer, run the Mi Flash Tool. Press refresh to detect the connected device. The serial number of the phone should appear on the list. If the device is not identified, check the installation of the ADB Interface and Bootloader drivers.

Once detected, click select and point the path to the unpacked firmware folder. Note: to roll back to an earlier version in the lower right corner of the program window, you must select the option clean all or clean all and lock.

⚠️ Warning: When selecting the “clean all and lock” mode, make sure that the firmware region (Global, China, EU) Blocking the bootloader with someone else’s regional firmware will lock the device (Hard Brick).

Xiaomi ADB Fastboot Tools

For advanced users who don’t want to mess around with manually typing commands or searching for specific versions of Mi Flash, there’s Xiaomi’s cross-platform utility ADB Fastboot Tools.It’s graphical interface software that automates many processes, including system debris removal and firmware reflashing.

The software allows you to quickly check the status of the device, unlock the bootloader (if the waiting timer allows), and download the desired firmware. The interface of the utility is intuitive: the left displays a list of available actions, and in the main part - the process logs, which reduces the risk of human error when entering commands.

To roll back the system through this tool, you need to go to the ROMs or Flasher tab, and you can download a link to the firmware archive or select it from the file, and the utility will determine the type of connection and suggest the appropriate actions, which is especially convenient when standard methods fail.

💡

Using specialized software like Xiaomi ADB Fastboot Tools minimizes the risk of errors when entering commands, but requires pre-installing Java on the computer.

Possible mistakes and ways to solve them

Users can face a variety of problems during a system rollback, and one of the most common is the Anti-Rollback error, which is a security mechanism that prevents the installation of firmware with a lower security index than the one that is sewn in the current version, and it is impossible to circumvent this limitation by software methods.

Another common problem is a bootloop. If the phone is constantly restarting after the firmware is done, before reaching the desktop, try a full Wipe Data reset via Recovery. If that doesn't work, the firmware itself may have been damaged or the recording process interrupted.

• 🔴 Error 5: Usually indicates driver or cable issues USB. Try another port or cable.
• 🟠 Flash Error: Often occurs when you try to flash Global firmware to a device with a Chinese bootloader without first changing the region.
• 🟡 Device not found: check if the driver is installed ADB and whether debugging is included USB (certain methods).

Also worth mentioning is the Mi Account issue. Once the data is rolled back and reset, the device will request authorization to the account that was tied before the reset. This is a feature of anti-theft protection. Make sure you remember the username and password, otherwise it will be extremely difficult to unlock the phone.

⚠️ Attention: Anti-Rollback mechanism (ARB) It can permanently lock the device when you try to roll back. ARB Current and target firmware through Fastboot commands.
