How to roll back Android on Xiaomi Redmi: a step-by-step guide

Modern software updates for Xiaomi and Redmi smartphones often bring not only new features, but also unforeseen bugs that can significantly reduce the comfort of using the device. Users often face a situation when after installing a new version of MIUI or HyperOS, the phone starts to run slower, discharge faster or there are critical interface errors.

The process of system rollback, or downgrade, requires care and strict adherence to the sequence of actions, as an error at any stage can lead to loss of personal data or complete inoperability of the gadget. You need to prepare all the firmware files, charge the battery and make sure that versions are compatible to avoid locking the bootloader or problems with Anti-Rollback. In this article, we will discuss in detail all the available methods for returning to the old version of Android, from simple ways through the settings menu to advanced methods using the computer.

Risk analysis and preparation for the system downgrade

Before you start any manipulation of system files, it is critical to understand that rolling back the Android version is not a routine procedure, but rather an emergency measure of recovery. The main obstacle you may encounter is the Anti-Rollback protection mechanism, implemented by Xiaomi to prevent the installation of outdated versions of software with known security vulnerabilities. If you activate this mechanism on your device and try to flash an older version, the phone can turn into a “brick”, which can only be restored in a service center.

⚠️ Warning: Trying to firmware a version with a lower Anti-Rollback index than the current one can lead to irreversible damage to the bootloader and complete loss of warranty.

The second important aspect is the complete loss of all user data in the downgrade process. Unlike a conventional “over-the-air” update that saves files and settings, system rollback always involves formatting internal storage. Wipe Data is a mandatory step without which the new (old) firmware simply won’t start or will not work properly. So backing up contacts, photos and documents is the first step that can’t be ignored.

To successfully perform the procedure, you will need a stable Internet connection to search for files, a computer with the Windows operating system (for some methods), and the original one. USB-A poor cable or a shaky connection can interrupt the recording process, causing system partitions to break. Also make sure that the battery is at least as high as the battery. 60-70%, As the process of scaling may take 10 minutes to an hour depending on the method chosen.

Determining the current version and finding compatible firmware

A key point in preparation is to accurately determine the model of your device and the current version of the installed operating system. An error in choosing a regional version (for example, trying to install Chinese CN firmware on a global Global or vice versa) can lead to a cyclic reboot or broken communication modules. To find out the exact version, go to the Settings → About the phone and pay attention to the build number and region.

Finding the right firmware file is best done on official resources or verified archives, such as MIUI bootloader or the official Xiaomi Community forum. You need to find the version that precedes your current one, or the one that has proven to be the most stable for your model. It is important to pay attention to the type of firmware: Recovery (for installation through the phone menu) or Fastboot (for installation via computer).

When selecting a file, make sure it is for your codename, such as guacamole for OnePlus or cepheus for Xiaomi Mi 9. Using firmware from another model, even if it has a similar name, is strictly prohibited and will lead to fatal hardware errors.

The method of rollback through the built-in update menu (Recovery ROM)

The safest and easiest way to roll back the Android version on Xiaomi is to use the built-in update mechanism through the Recovery firmware file.This method does not require an unlocked bootloader (in most cases, if the versions are close) and a computer, all actions are performed directly on the smartphone. However, it is worth remembering that the standard update menu often blocks the installation of the older version, giving the message “Current version is newer”.

To get around this limitation and get the system to accept the downgrade, you can use the hidden developer menu. To do this, open the firmware file, select "Select File" and quickly click 10 times on the MIUI logo in the center of the screen. If the hidden menu is activated, three dots will appear in the upper right corner, clicking on which you can select "Select File Again" or Forced installation.

Once activated, select the downloaded.zip file with firmware. The system will check the integrity of the file and, if the version allows rollback without blocking Anti-Rollback, will suggest a reboot for installation. If the system says that the file is corrupt or the version is not suitable, you will have to use a more radical method through Recovery mode.

Using Recovery Mode for Manual Installation

If the standard method didn’t work, you can manually install it via Recovery Mode, which is more versatile, but requires renaming the firmware file and getting it into the right menu. First, rename the downloaded firmware file to update.zip (make sure the extension is.zip, not.zip.zip) and place it in the root folder of the smartphone’s internal memory.

Then you turn off your phone and enter Recovery mode, holding the power and volume buttons at the same time. After the Mi logo appears, you can release the power button while continuing to hold the volume button. From the menu that appears, select the language (usually English and Chinese) and go to Install update.zip or the like.

⚠️ Note: If there is no install point from a memory card or phone in the Recovery menu, then your bootloader is locked, and this method will not work without first unlocking through Mi Unlock.

Once the file is selected, the system will request a confirmation to clear the data. Confirm the action, and the flashing process will begin. The screen can go out and light up several times, which is normal behavior. Once the process is complete, the phone will automatically restart, and the first download can take up to 10 minutes, as the system will recreate the file structure.

Fastboot and Mi Flash Tool on PC

The most reliable way to bypass most software locks and ensure a system rollback is to use the Mi Flash Tool utility on your computer. This method requires a Fastboot version of the firmware (.tgz archive), which you need to unpack into the root folder of the disk (the path should not contain Cyrillic alphabets or spaces), and you need to install the ADB and Fastboot drivers.

Put your smartphone into Fastboot mode by slamming the power and volume button when the device is off. Connect your phone to your PC with a cable, launch the Mi Flash Tool and press the Refresh button. If the device is determined, choose the path to the folder with the unpacked firmware. At the bottom of the window, it is important to select Clean all mode, since a downgrade without cleaning the data is impossible.

Pressing Flash will start the partition writing process, at which point it is strictly forbidden to turn off the cable or interrupt the power of the computer, the status bar in the program will show progress, and after successful completion, the phone will go into the boot mode of the new system. 50-90%, Maybe the problem is USB-port-car.

Problem Solving and Possible Errors in Recoiling

In the downgrade process, users often encounter various errors that can stop the process. One of the most common is Recovery's Error 7, which occurs when you try to install firmware that is not designed for a given model or region, the solution is to check the checksum of the file and re-load the archive from another source.

Another common problem is a cyclic bootloop after installation, which may mean that data from the old version of the system is in conflict with the new one, in which case you need to re-enter Recovery mode and execute the command Wipe Data and Wipe Cache, then try again to boot, if this does not help, it may be damaged the boot partition, and you need to flash it through the Fastboot.

• 📱 Error 1012: Usually indicates problems with connecting to the server or the Internet when you try to activate.
• 🔒 Anti-Rollback Protected: Fatal bug, meaning that rollback protection prevents you from installing an old version.
• 📉 Lack of space: Clean the phone’s internal memory before copying the firmware file.

⚠️ Warning: If after all the manipulations the phone does not turn on and does not respond to the buttons, the bootloader may be damaged, and the intervention of specialists using the programmer is required.

💡

Use it. USB-hub without additional power sources to connect the phone to the PC to avoid power surges during firmware.

It is also important to consider that after rolling back to an older version of Android, some apps may stop working properly, requiring an update or, conversely, installing older versions. APK-Google banking applications and services may require re-authorization and device security checks.
