Many users are faced with a situation where, after an automatic update to the MIUI operating system or a new HyperOS, the smartphone begins to work unstable, there is increased battery consumption, the usual functions disappear, and the interface becomes less responsive, in which case the only reasonable way out is to return to the previous, more stable version of the software known as downgrade.
The rollback procedure is not a standard feature that can be activated with a single button in the settings, since Xiaomi developers block the ability to install an older version on top of the new one for security reasons. You will need to perform a number of technical actions, including unlocking the bootloader and using specialized software on the computer. Ignoring security rules at this stage can lead to the device becoming a “brick”.
In this article, we will discuss in detail how to make an old update on Xiaomi, what tools are necessary to successfully perform the procedure and how to avoid critical errors. Full reset of user data is a prerequisite when switching to an earlier version of firmware. Carefully study all the steps before you start active actions with your gadget.
Why is it necessary to roll back the version of the software
The main reason smartphone owners are looking for a way to make an old upgrade is the appearance of bugs in new builds. Developers often release global updates that do not pass enough testing on all device models, which leads to errors in the communication modules, camera or energy saving system.
Another factor is changing the user interface or removing familiar features. Newer versions of Android and MIUI often change the logic of the system, which causes discomfort for users who are accustomed to a certain algorithm of actions.
- 📉 Unstable work: frequent reboots, interface freezes and spontaneous closure of applications.
- 🔋 Autonomy problems: a sharp increase in battery consumption for no apparent reason.
- 📡 Communication failures: network loss, problems with Wi-Fi or Bluetooth modules.
It's important to understand that rolling back is a last resort. Before you do this, try doing a full Wipe Data reset on the current firmware version, which often helps to resolve software conflicts that have arisen after an update without the need for complex manipulations with the bootloader.
Preparation for the downgrade procedure
Before you start the process of returning to the old version of the software, you need to conduct thorough preparations, the security of your data is at risk, as the procedure requires a complete cleanup of the internal memory of the device, back up all important contacts, photos and documents in the cloud or on your computer.
The second critical step is unlocking the bootloader. Without this step, you can’t install an older firmware version, because the Mi Unlock protection system will not allow you to flash it back. The unlocking process can take from a few days to a week, as it requires waiting for confirmation from Xiaomi.
☑️ Preparation for firmware rollback
Also make sure that your computer has all the necessary drivers to work with Xiaomi devices in Fastboot modes and ADB. Use the original. USB-cable and connect the device directly to the motherboard port, avoiding use USB-hubs that can cause connection instability during data recording.
Finding and Choosing the Right Version of the Firmware
The key to making an old Xiaomi update is finding the right firmware file. You will need a full firmware version (Recovery ROM or Fastboot ROM) rather than an update package. The files must match your device’s region (Global, EU, Russia, China) or there may be compatibility errors.
There is an important rule of regionality: you can not reflash the device with global firmware to Chinese or vice versa without special manipulation of the regions, the region of the firmware must coincide with the region in which the device was originally registered, or you will need to change the region through the engineering menu, which also carries risks.
| Type of firmware | File extension | Method of installation | Difficulty |
|---|---|---|---|
| Recovery ROM | .zip | Through the Recovery menu | Medium |
| Fastboot ROM | .tgz | Through PC and Mi Flash | Tall. |
| Updater Package | .zip | Local Update | Low (not for downgrade) |
Downgrades are most commonly used with Fastboot ROM, as they allow clean installation of the system.Firmware files are best downloaded from trusted resources such as the official website miui.com or authoritative forums to rule out the presence of malicious code in the system.
Where to look for archive versions of the firmware?
Recovery Mode (Clean Install)
One way to make an old update is to use Restore Mode, which is appropriate if the difference between versions is not too big and the bootloader is already unlocked. First download the firmware archive in.zip format and rename it to update.zip, placing it at the root of internal memory.
Then you need to switch to Recovery mode. To do this, turn off your smartphone and press the combination of the buttons Volume up + Power. From the menu that appears, select a language (usually English or Chinese) and go to Wipe Data. Confirm the data cleanup, then return to the main menu.
⚠️ Note: If you try to install an older version through the Select File menu without first clearing the data, the system will give an error "Can't verify update.
After cleaning, select Install update.zip (or “Choose update package” –> “Internal storage”). The system will start checking the file and, if the version allows rollback, start the installation process. If the security blocks the downgrade, you will see a message that you can not install, and then you will have to use the method through Fastboot.
Fastboot and Mi Flash Tool
The most reliable and versatile way to return the old version of the software is to use the Mi Flash Tool utility on your computer. This method requires an unlocked bootloader and a firmware file in.tgz format. Unpack the archive with the firmware in the root of the disk, preferably so that the path does not contain Cyrillic characters.
Run the Mi Flash Tool program on behalf of the administrator. Put your smartphone into Fastboot mode by pressing Volume Down + Power buttons until the hare appears in the repair cap. Connect the device to your PC and press the Refresh button in the program to identify the phone.
From the bottom menu, select Clean all firmware mode, which is critical because it ensures that the memory is cleaned and the old version is installed correctly. Press Flash and wait for the process to finish, which can take 5 to 15 minutes.
- 🚀 Clean all: Complete data cleanup and firmware installation (recommended for downgrade).
- 💾 Save user data: attempts to save data (often resulting in errors when changing versions).
- 🧹 Clean all and lock: Clean, install and lock the bootloader (only if you return the runoff).
Once successful, the status will be labeled success, and the phone will automatically restart. The first turn on may last longer than usual, as the system generates new caches and configuration files.
Possible mistakes and ways to solve them
Downgrade users often encounter various errors, and one of the most common is Missmatching image and device, which occurs when trying to flash firmware from another model or region, in which case you need to double-check the device's encoding and file matching.
Another common problem is the signature verification error or anti-rollback. Some versions of MIUI have a built-in security mechanism that physically prohibits the installation of the version with a lower security index. You can not bypass the Anti-Rollback without consequences, and an attempt to force the device will lock.
💡
If the Mi Flash Tool is running a Flash All Except Data Storage Failed error, try using an older version of the Mi Flash program itself (e.g., 2018), as newer versions may have modified verification algorithms.
There may also be a driver error when the computer sees the device as “Unknown Device”, in which case you need to manually update the driver through the Device Manager, indicating the path to the folder with the Qualcomm or Xiaomi drivers included in the utility package.
⚠️ Warning: If the progress of the bar has been stalled for a long time during the firmware process through Fastboot or there is a red error text, do not turn off the cable immediately.
