How to Downgrade Xiaomi’s Firmware Version: A Complete Guide to Recoil

Modern updates to the MIUI shell and the new HyperOS often bring not only desirable features, but also unforeseen problems. Owners of Xiaomi, Redmi and POCO smartphones often face rapid battery discharge, overheating or software errors after installing a new version of the software. In such situations, the only effective solution is to return to a more stable build that worked without failure.

The process of downgrading the firmware version, or downgrade, is technically more complicated than a conventional update and requires the user to be careful. The critical point is to delete all data completely, as a direct transition to an older version without a complete cleanup can lead to an endless cycle of reboots, USB-cable and an exact copy of the required firmware file.

Before you take action, you need to understand the risks, and if you do it wrong, you can lock the bootloader or, in rare cases, turn the device into a brick, but if you follow the algorithms you've tried and use the official tools, you can successfully return the system to its previous state.

Risk analysis and preparation for downgrade

The first step before any manipulation of the system software is to unlock the bootloader. Without this procedure, installing an older version of the firmware is impossible, since the Mi Flash security system will not allow you to write old files on top of new ones. The unlocking process takes from 7 to 168 hours of waiting after you link your account, so plan your actions in advance.

The second, equally important aspect is choosing the right firmware version. You can't install any random build; there's a strict hierarchy of Android versions and regions. For example, you can't go from global to Chinese without completely flashing, and switching from Android 13 to Android 11 often requires special techniques, such as Clean Install via Fastboot.

⚠️ Attention: Downgrade automatically initiates a full Wipe Data reset. Even if you plan to upgrade, the system will force the internal memory to be cleaned. Be sure to back up photos, contacts and documents in the cloud or on your PC.

Trying to flash global firmware onto a device with a Chinese bootloader (or vice versa) will result in a signature verification error. Make sure the region code in the firmware file name matches the region of your device (e.g. EU for Europe, RU for Russia, Global for the international market).

Required tools and drivers

To successfully pull back, you'll need a suite of specialized software. The standard smartphone tools won't be enough, because we need to interact with low-level download protocols. The main tool will be the Mi Flash Tool, which is the official programr for Xiaomi devices.

In addition, the system needs the right ADB and Fastboot drivers. Without them, the computer will not be able to recognize the smartphone in diagnostic mode. Often users face the problem when the phone is identified as an unknown device, which makes firmware impossible. Install the drivers must be done before connecting the phone in Fastboot mode.

The table below contains a list of the necessary software and its purpose:

Pay special attention to quality USB-Cheap cables designed only for charging may not provide stable data transfer, which will interrupt the firmware process in the middle. Use the original cable or certified analogue with support for high data rates.

Use it. USB-port 2.0 It's on the back of the system unit. 3.0/3.1 Some motherboards may cause compatibility issues with older Fastboot protocols.

Finding and downloading the correct version of the firmware

The hardest part for a beginner is finding the version you want to return to. The official site doesn't always keep archives of old builds in the public domain, so you often have to resort to third-party but proven aggregators. It's important to understand the difference between Recovery and Fastboot firmware.

Recovery firmware has the.zip extension and is designed to be installed via the recovery menu or built-in updater. Fastboot firmware has the.tgz extension and is used exclusively through the computer and Mi Flash program. For downgrade, we need the second option, as it allows you to clean the partitions and bypass the version check.

When searching, look for the version encoding. For example, V14.0.3.0.TKGMIXM points to Android 13 (T), Global (MI) region, and Mix firmware type. If you try to install the China (CN) version on a global device, the process will end in error.

Make sure the downloaded file is not corrupted. Once downloaded, it is recommended to check the checksum (MD5 or SHA1) if it is provided by a source.A damaged archive can cause Mi Flash to display an unpacking error or, worse, to write the broken data to the system partition.

Method 1: Recovery Mode (Local Update)

This is suitable for cases where the difference between versions is small or when the system allows you to "override" the current version. However, if you are trying to roll back to a much earlier version, the standard installer may give an error "Can't verify update", in which case you will need to rename the file.

First, place the downloaded firmware file (renamed update.zip) in the root of the phone's internal memory. Then go to Settings → About Phone → MIUI version. Click three dots in the corner and select "Select firmware file."

If the standard path doesn't work, use the button combination to log in to Recovery. Turn off your phone and press Volume Up + Power. From the menu that appears, select the language and click "Wipe Data," then try installing the firmware through the Connect with MIAssistant menu or the standard updater if available.

⚠️ Note: If the phone goes into an endless bootloop after installing via Recovery, don’t panic.You’ll have to use the Fastboot method with full cleaning described below, as a simple installer couldn’t replace system partitions correctly.

This is the most reliable and recommended by experts way to downgrade the version, it ensures a clean installation of the system without remnants of old configuration files. First, put your smartphone in Fastboot mode, holding the Volume Down + Power buttons simultaneously before the logo with the android hare repairing appears.

Connect the device to your computer and launch the Mi Flash Tool. Press the Refresh button to allow the program to detect the device. Enter the path to the folder with the unpacked firmware in the address bar. It is critical to select the data cleanup mode.

At the bottom of the program window, you'll see three options. You'll need to select Clean all for a downgrade. The "Save user data" option will likely lead to an error or a reboot cycle, as the new and old data structures are incompatible.

The algorithm of actions in Mi Flash:




1. Click 'Refresh' (Connection Check)




2. Click '...' (Selecting a Firmware Folder)




3. Select 'Clean all' (Cleaning all data)




4. Click 'Flash' (Running the process)

When you press the Flash button, you start recording. The green progress bar shows status. Don't touch the cable or turn off the computer. At the end of the process, the phone automatically restarts. It can take you up to a point. 10-15 minute.

💡

Using the “Clean All” mode in the Mi Flash Tool is a prerequisite for successful downgrading of the firmware version, as it prevents file system conflicts of different versions of Android.

Solving common mistakes

In the process of downgrade, users often encounter error codes. One of the most popular is Miss matching image. It means that you are trying to install firmware from another model or region. Check the device code in Fastboot (it appears on the phone screen) and compare it to the name of the firmware file.

Another common problem is driver error: If the device manager detects the device with a yellow exclamation point or as "QHSUSB_BULK", You need to reinstall the drivers Qualcomm or Xiaomi USB Driver manually. Sometimes it helps to just reconnect the cable to another port.

There is also a "Not enough space" error, which occurs if you try to install firmware that is larger than the amount of free space in a particular partition, or if the firmware file is damaged when you download it.
