Many users are faced with a situation where, after automatically updating the MIUI or HyperOS operating system, the smartphone begins to work unstable, the battery runs out in half a day, the interface slows down, and the usual functions cease to respond, at such times, the only way out is to return to an older but proven version of the software.
The downgrade process is much more complicated than a regular update installation, as manufacturers block the ability to install the old version on top of the new one for security reasons. You will not only need to download the file, but also properly prepare the device, unlock the bootloader and choose the right firmware method.
In this article, we will discuss all the available ways to return the system, the necessary tools and the risks that you will face. carefully study the theoretical part before starting practical actions to avoid turning a smartphone into a brick.
Why does the rollback occur and when it is necessary
The main reason Xiaomi and Redmi owners are looking for ways to downgrade is optimization. Newer versions of the shells often contain bugs that developers do not have time to fix before release. Users notice overheating of the processor, problems with the communication module or improper camera performance.
Also, some users prefer the old interface design or functionality that has been removed in new builds. For example, changing the structure of the settings menu or removing the ability to sort applications can be a decisive factor.
There is also a compatibility issue: some banking applications or enterprise services may not work properly on MIUI betas, and in such cases, returning to a stable branch is a prerequisite for normal operation of the gadget.
⚠️ Attention: The downgrade process almost always results in the complete removal of all data from the device.
It is important to understand the difference between firmware types. You can’t simply install a China version on top of Global or vice versa without a complete cleanup, and sometimes without an unlocked bootloader. Install an older firmware version on top of a new one is only possible through Clear Install Fastboot mode.
Preparation of the device and assembly of necessary files
The first step is to find the correct firmware file, you need to find a version that is older than the one installed now, download current and archived builds on official resources or proven aggregator portals, make sure that the file is designed specifically for your model (codename, for example, davinci or vayu).
To work you will need a computer running Windows, the original USB-cable (preferably short and high-quality) and installed Xiaomi drivers USB Driver. without the right drivers, the computer will not see the smartphone in firmware mode.
You also need to activate USB debugging mode. Go to Settings → About Phone and click on the build number seven times to become a developer. Then, in the Developer Menu, include Debugging over USB and Factory Unlock.
☑️ Checklist before downgrade
Don’t forget to check the status of your Mi Account. If the device has the “Device Search” feature enabled, be sure to untie your account before you run the firmware, otherwise after resetting, the phone will require a password from an old account that you may have forgotten.
Recovery Methods through Recovery Mode
The easiest, but often blocked, way is to use a built-in recovery, which only works if the target firmware version is newer or equal to the current one, or if you're sliding between regions of the same version. It's rare for a downgrade, but worth a try.
Copy the downloaded firmware file (.zip archive) to the root of the phone's internal memory. rename it to update.zip for convenience, though this isn't always necessary.Reboot the smartphone to recovery mode by clamping the Volume Up + Power button combination.
From the Recovery menu, select the language (usually English or Chinese) and click Install update.zip. If the system allows you to install the old version, you will see the progress bar process. If the version is too old, the Can't verify update error will appear.
⚠️ Warning: If Recovery gives a check error, don’t try to get around it with multiple reboots.You’ll need the unlocked bootloader method and Fastboot mode.
This is a good way to do this, because it doesn't require a computer, but it's less than 20 percent effective at downgrade, and most often, the Anti-Rollback system protects against the installation of older versions through the standard menu.
Use of Fastboot Mode and Mi Flash
The most reliable way to roll back firmware is to use the Mi Flash Tool in conjunction with Fastboot mode.This method allows you to force all memory partitions to be rewritten, ignoring version checks, but requires an unlocked bootloader (Unlock Bootloader).
First, download and install the Mi Flash Tool on your computer. Unpack the downloaded firmware (the archive should be in.tgz or.zip format, but unpacked into a folder with a Latin name without spaces). Connect the phone turned off to your PC by holding the Volume Down button. The screen should light up with an image of a hare fixing an android.
Run the program on behalf of the administrator, press Refresh and make sure that the device is determined (its serial number will be displayed). Press the Choose button and specify the path to the folder with the unpacked firmware.
At the bottom of the window, select firmware mode. For a downgrade, it is critical to select the Clean all option. Save user data option does not work when you downgrade the version and will cause an error. The Clean all and lock option will block the bootloader, which can be dangerous if you are flashing a region (for example, Global to China).
| Parameter | Description | Recommendation in downgrade |
|---|---|---|
| Recovery ROM | Update via phone menu | Not suitable for a kickback |
| Fastboot ROM | Complete image of the system | The only working option |
| Clean all | Erasure of all data | Definitely for the downgrade. |
| Save user data | Data retention | It'll cause a rollback error. |
After selecting the mode, press Flash. The process will take 100 to 300 seconds. Do not turn off the cable or touch the phone until the green Success label appears.
Unlocking the loader: a mandatory stage
If your bootloader is locked, Mi Flash will give you an error when you try to downgrade. Unlocking is an official procedure, but it takes time. You'll need a Mi Account tied to the device and a Mi Unlock utility on your PC.
Apply for unlock through the Developer Menu → Mi Unlock Status. Once you have your account tied, you have to wait a certain period of time (usually 7 to 168 hours) before the server allows you to unlock.
What happens if you miss the wait?
After the wait period expires, launch Mi Unlock in Fastboot mode and press the unlock button. The device will be completely cleared, but the bootloader will be open, which will allow you to install any versions of the software, including the old ones.
Keep in mind that on some newer models with MediaTek processors or newer versions of Android, the procedure may be different and require an authorized service center account.
Possible mistakes and ways to solve them
In the process of downgrade, users often encounter the error Error: Miss matching image and current device. This means that you try to flash firmware from another model or region without the appropriate lock.
The Anti-Rollback check failed error indicates that the rollback protection mechanism has worked, which happens if you try to roll back to a version with a lower security Patch Level than the one that is now, and you can’t get around this software, just by flashing to the same version or a newer version, or using service boxes (for experienced ones).
⚠️ Attention: Interrupting the firmware process (cable disconnection, battery discharge) in 90% of cases leads to the failure of the device. USB-port.
If the phone went to Bootloop after a failed downgrade, try logging into Recovery and doing Wipe Data.If that doesn't work, you'll need to re-running through Fastboot with a selection of Clean all.
💡
Expert advice: Before starting firmware, close all unnecessary programs on your PC, including antivirus (during the process), so that they do not block Mi Flash access to the computer. USB-port.
