Modern Xiaomi, Redmi and POCO smartphones often receive updates that don’t always please users. Sometimes a new version of the MIUI or HyperOS operating system contains errors, causes increased battery consumption or simply does not like visually. In such situations, the only reasonable way out is to return to an earlier, stable build. However, the official website of the manufacturer rarely stores old versions of files in the public domain, which forces owners of gadgets to look for alternative ways to download.
The process of finding and installing the previous version of the software requires care, as incorrect actions can lead to data loss or software failure. You need to know exactly your device model, firmware region and current version of Android, so as not to turn the phone into a brick. The firmware archive is not just a set of files, but a structured database where each build has its own unique identifier. Before you start downloading, make sure that you understand the difference between the Global, EU and CN versions, as they are not allowed to be mixed.
In this article, we will examine proven sources for downloading legacy versions of software, explain the nuances of system rollbacks and provide a step-by-step algorithm of actions. Critically, ignoring this rule will lead to an error in the installation.
Why You May Need to Reverse a Software Version
Users often look for ways to return a previous version of the shell for various reasons: sometimes developers release “raw” updates that contain critical bugs that affect the operation of communication modules or the camera. Other times, the new version of MIUI may be too heavy for the device’s processor released several years ago, leading to micro-freezes of the interface and reduced autonomy.
Another common reason is to remove familiar features: With each major update, Xiaomi changes the logic of the system, hides the necessary settings or introduces aggressive advertising that is difficult to turn off. Returning to a time-tested build allows you to restore the comfort of using a smartphone without having to get used to new, not always convenient changes.
- 📉 Decreased performance: after the update, the smartphone began to slow down or warm up.
- 🔋 Battery problems: new software causes abnormally fast battery discharge in standby mode.
- 📡 Communication errors: network signal is lost, stopped working GPS Bluetooth after installing the update.
It is worth noting that the desire to install old firmware often occurs in users who accidentally upgraded to beta and want to return to stable channel (Stable), in this case, the standard update “over the air” will not help, since the system does not know how to roll back itself, manual intervention and the presence of an installation file of an earlier version is required.
Where to find the archive of official firmware Xiaomi
Finding a reliable source to download system software is the first and most important step.The official website miui.com often only shows the latest available version for each model, hiding the update history. Therefore, enthusiasts and specialists use specialized third-party resources that aggregate data directly from the company's servers or are collected by the community.
One of the most authoritative resources is the Xiaomi Firmware Updater project, which automatically tracks changes on Xiaomi servers and stores links to every version ever released. Here you can find files for both recovery (Recovery ROM) and flashing through your computer (Fastboot ROM).
Another popular option is forums such as 4PDA or XDA Developers. In thematic branches of specific models, users often post file mirrors that have already been verified by other community members. This reduces the risk of downloading a corrupt file. However, when using forums, always check the date of publication of the message and comments to make sure that the link is relevant and integrity.
| Resource | Type of access | History of the existence of | Security |
|---|---|---|---|
| Xiaomi Firmware Updater | Automatic. | Complete. | Tall (official mirrors) |
| Official MIUI website | Hand-held | Only the last one. | Maximum |
| 4PDA Forum | Manual/Community | Depends on the topic. | Medium (requires inspection) |
| Mi Community | Hand-held | Partial | Tall. |
When downloading, pay attention to the file extension. To install through the recovery menu, you need an archive with the.zip extension, and to install through the PC in Fastboot mode, you use the.tgz file. Do not try to rename files or change their structure, this will violate checksums and make installation impossible.
💡
Always check the checksum (MD5 or SHA1) of the downloaded file if it is listed on the site, which ensures that the file is not corrupted during download and does not contain viruses.
Differences between Recovery and Fastboot Firmware
Before you click the Download button, you need to be clear about what type of firmware you need. An error in choosing the file type will either prevent the phone from seeing the update or will give an error when you try to install it. The main differences are in the way the installation is done and the amount of rights that the user gets.
Recovery ROM is the easiest option for the average user. The firmware file has a.zip extension and weighs about 3-5 GB. Installation is done directly through the phone menu or the built-in update bootloader. This method does not require a connection to the computer and special drivers, but has limitations: you can not change the firmware region (from Global to EU) and it is difficult to roll back the version without an unlocked bootloader.
Fastboot ROM is designed for advanced users and service centers. The file has a.tgz extension and weighs more, often around 4-6 GB, as it contains more system partitions. It requires a PC, a USB cable, a Mi Flash Tool utility and a Fastboot-mode smartphone. The main advantage is the ability to completely clean the system and change the region, but this method is more complex and carries slightly greater risks if used ineply.
⚠️ Note: You cannot install Recovery firmware in one region over the firmware in another region (e.g. China firmware in Global) without first unlocking the bootloader».
The choice between these two types depends on your specific situation. If you just need to upgrade or upgrade within the same region, the Recovery version is enough. If you want to change the region or the phone is locked to a particular version, you will have to use Fastboot and unlock the bootloader through the official Xiaomi website.
What is a Bootloader (Bootloader)?
Preparation of the device for flashing
The success of the rollback or installation of the old version depends on the quality of preparation. Negligence at this stage can lead to the loss of personal photos, contacts and passwords.
First, create a full backup of your data. Even if you plan to just upgrade on top, there is always a risk of failure. Use Google's cloud services or MIUI's built-in backup to save settings and applications. Photos and documents are best copied to your computer or external hard drive.
The second important step is to ensure a stable power supply. 60%, It's a power-intensive firmware process, and if the phone turns off in the middle of the system partition recording, it can cause a cyclical reboot. USB-cable USB 2.0/3.0 on the back of your computer if you are working through a PC.
☑️ Checklist of preparations
Don't forget to check the space in the internal storage. The firmware file takes several gigabytes, and after unpacking it will need even more space for temporary files. If there is not enough memory, delete unnecessary applications or transfer media files to the memory card (if supported).
Instructions for installing the old version through Recovery
This is a method that is suitable for those who do not want to use a computer and whose bootloader is unlocked or the versions are the same. We will use an inbuilt update mechanism. First, the downloaded.zip file must be placed in the root folder of the phone's internal memory. Do not put it in folders with photos or documents so that the system can find it.
Next, go to the phone settings. The path may vary slightly depending on the version of MIUI, but it usually looks like this: Settings → About Phone → MIUI version. Click three dots in the upper right corner of the screen and select "Select firmware file." The system will scan the memory and, if the file is correct, prompt you to start installing.
If the phone says that the file is not found or the version is newer than the current one, you can try another method through the Recovery menu. To do this, turn off the phone and press the combination of the Up + Power buttons. In the menu that appears, select the language (English or Chinese) and click Install zip. Find your file in the list and confirm the action.
⚠️ Note: If you try to roll back the version (Downgrade) through Recovery, the system may block the installation, requiring data to be cleaned. If you agree to clean up, all files will be deleted. Make sure you have a copy of important data.
Once confirmed, the verification and installation process will begin, which can take anywhere from 5 to 15 minutes, and the screen can go out and light up, which is normal, and when it's done, the phone will suggest that you reboot, and the first run after the firmware will take longer than usual, because it's the system that adjusts the components.
💡
The method through Recovery is safe and simple, but does not allow you to change the firmware region or roll back to very old versions of Android without first unlocking the bootloader.
Fastboot and Mi Flash Tool
If the Recovery method didn't work or you need to change region, you'll have to use a computer. You'll need the Mi Flash Tool. Download it from an official source and install it on a PC. Also make sure your computer has ADB and Fastboot drivers installed, which are usually bundled with the toolkit.
Download the firmware archive.tgz to a separate folder. The path to the folder should be short and not contain Cyrillic alphabets or spaces, for example: C:\Xiaomi_ROM\. Inside the folder, files should be visible. flash_all.bat Start the Mi Flash Tool on behalf of the administrator.
Put your phone in Fastboot mode. To do this, plug the device off to your PC by holding the Volume Down button. The screen will show a bunny in a repair hat or the words FASTBOOT. In the program, press the Refresh button so that the PC sees the device. Select the firmware mode at the bottom: Clean All (full clean) or Save User Data (data saving, does not always work when rolled back).
flash_all.batPress Flash and wait for completion. The process will take 200 to 600 seconds. At this time, it is strictly forbidden to turn off the cable or restart the computer. Once the green Success label appears, the phone will automatically restart.
