Returning Chinese firmware to Xiaomi: from unlocking the bootloader to installing MIUI China

Transition from global or European firmware to Chinese version MIUI — The challenge faced by many owners of smartphones Xiaomi, Redmi or POCO. The reasons can vary from wanting to get the latest updates before the rest to having to use features available only in the Chinese build (for example, advanced camera settings or unique themes). OTA-It requires unlocking the bootloader, working with fastboot, and sometimes bypassing Xiaomi’s restrictions, which tighten security policies every year.

In this article, we will look at all the steps of returning to Chinese firmware, from the preparation of the device to the final configuration of the system. You will learn what tools you will need, how to avoid common errors (for example, locking a Mi Account or a “brick” device), and what to do if something goes wrong. Importantly, the procedure is suitable for most Xiaomi models, but there are nuances for devices with Qualcomm and MediaTek processors, and for smartphones released after 2022. If your device is one of the latter, read the section on bypassing antirollback carefully.

Why are users returning to Chinese firmware?

Global and European versions of MIUI often lag behind Chinese versions of the functionality, and here are the main reasons why users decide to switch:

• 📅 Early access to updates. Chinese firmware gets new versions MIUI Security patches 1-3 months ahead of global security.
• 🎯 Unique functions. MIUI China has advanced camera settings (including manual modes for all modules), additional gestures, hidden themes and animations.
• 🔧 More customization options: The Chinese version allows for deep customization of the interface, including changing system fonts and icons without root rights.
• 🚀 Better performance: In some cases, Chinese firmware is better optimized than global, especially on flagships (Xiaomi) 13/14, Redmi K60).
• 🇨🇳 Support for Chinese services: If you use apps like WeChat, Alipay, or Douyin, they are more stable on the original firmware.

But there are downsides: the lack of Google Play Services (they will have to be installed separately), possible problems with Google services (for example, Google Pay may not work), and the risk of blocking the Mi Account if you do not do the right thing. Since 2023, Xiaomi has tightened the check of devices for compliance with the region: when installing Chinese firmware on a global device, protection that requires confirmation through a Chinese phone number can work.

Preparation of the device: what to do before the firmware

Before you start changing your firmware, you need to follow a few critical steps, and skipping any of them can lead to locking the bootloader, loss of data, or even “bricking” the smartphone.

⚠️ Note: If your device was purchased in Europe or Russia and originally came with global firmware, installing the Chinese version may result in a loss of warranty.

Here's what you have to do:

1. Back up all your data. Use Mi Cloud or third-party tools like Titanium Backup: 📱 Contacts, SMS and call log (export to file). 📸 Photos and videos (copy to PC or cloud). 🔑 Logins and passwords from the browser (synchronize with Google Account). 🎮 Game savers (use Helium or root reservations).
2. Check the device model and the current firmware. Go to Settings → About the phone and write it down: 📋 Device model (e.g. Redmi Note 12 Pro)+ 5G). 🔢 Version MIUI (for example, MIUI Global 14.0.5). 🔄 Assembly number (e.g, TP1A.220624.014).

Make sure the loader is unlocked

Mi Unlock

Charge your smartphone at least 60%

Download the necessary tools

• 🖥️ Mi Flash Tool (for fastboot firmware).
• 📱 ADB Fastboot drivers for your OS.
• 🔗 Firmware MIUI China for your model (only from the official Xiaomi website or trusted forums like the one in China) XDA Developers).

Pay special attention to firmware selection. The wrong version (for example, for another region or processor) can lead to a hard brick - a state where the device is not turned on and not determined by the computer.

Unlocking the loader: step-by-step instructions

Without an unlocked bootloader, you can’t install Chinese firmware. Xiaomi blocks this default feature to protect against unauthorized changes. The unlock process takes 7 to 15 days (due to the mandatory waiting for confirmation from Xiaomi servers) and requires you to link your Mi Account to the device.

Here's how to do it:

1. Connect your Mi Account to your device: Go to Settings → Xiaomi Account. Sign in (if not, sign up) Activate Device Search and Data Sync.
2. Launch the tool and log in to your account: Connect your phone to your PC in fastboot mode (turn off the device, then press Volume Down + Power). In Mi Unlock, press Unlock and follow the instructions.

Wait 168 hours (7 days)

Xiaomi

• ❌ Unlock the Mi Account from the device.
• ❌ Perform reset settings.
• ❌ Stripping the device with other methods.
• Repeat the unlocking process after the deadline. Now the bootloader will be unlocked.

⚠️ Note: If you previously unlocked the bootloader, but then updated the firmware through OTA, Check the status of the command in fastboot: fastboot oem device-info If the answer Device unlocked: false - the bootloader is blocked.

For devices released after 2022 (Xiaomi 13/14, Redmi Note 12 and later), additional confirmation via a Chinese phone number may be required. If you don’t have one, use services like SMS-Act to get a temporary number.

💡

If the Mi Unlock Tool gives you a "Couldn't unlock" error, try using the old version of the program (e.g. 3.5.1118.51) or running it in Windows 7 compatibility mode.

Download Chinese firmware: where to take and how to choose

Official Chinese MIUI firmware is distributed through several sources, but not all are secure; using files from questionable sites can lead to the installation of modified (and potentially malicious) versions.

• 🌐 Xiaomi official website: Go to the new.c.mi.com/global/miuidownload. Choose your model and download the China Stable or China Developer version. Pay attention to the release date - fresh firmware is published on Fridays.

Firmware comes in two types:

• 📦 Recovery ROM — It is installed via Mi Recovery, suitable for updates over the air without loss of data.
• 🖥️ Fastboot ROM — It is installed via the Mi Flash Tool. Requires an unlocked bootloader and a complete data reset.

To switch from global to Chinese firmware, it is recommended to use Fastboot ROM, as it guarantees a complete replacement of all partitions, including modem and boot. Recovery ROM can lead to conflicts if the versions of MIUI are very different.

When downloading, pay attention to the file name. The correct firmware for Xiaomi 12T Pro (codename diting) will look like this:

diting_images_V14.0.8.0.TLCCNXM_20231012.0000.00_13.0_cn_50d2a03b5a.tgz

Where:

• Diting is the code name of the model.
• V14.0.8.0.TLCCNXM is a version of MIUI (CN - China).
• 20231012 - Assembly date.
• cn is the region (China).

Installation of Chinese firmware through Fastboot

It's the most reliable method, but it requires a complete data reset, and if you haven't done a backup in the previous stages, go back and save important information.

You'll need:

• 🖥️ Windows computer (7/10/11).
• 🔌 Cable USB (preferably original).
• 📱 Unlocked loader.
• 📁 Fastboot firmware ROM (foldered).
• 🛠️ Mi Flash Tool (last version).

Step-by-step:

1. Launch the Mi Flash Tool and press Select, then specify the folder with the unpacked firmware.

Flash

After a successful firmware

The device will automatically restart. The first boot can take up to 15 minutes.

⚠️ Note: If the Mi Flash Tool is flash not done or anti-rollback check fail, it means you are trying to install an older version. MIUI, In this case, 1. Download a newer firmware (check build date). 2. Or use an anti-rollback patch (for power users).

After the first download, you will need to:

• 🌐 Connect to Wi-Fi.
• 🔑 Sign in to the Mi Account (required!).
• ⚙️ Complete the initial setup (you can skip most steps).
• 📱 Install Google Play Services (if required).

💡

Use only official firmware from Xiaomi or trusted sources. Installing custom or modified builds can result in the blocking of Mi Account and loss of IMEI.

Bypassing the antirollback: what to do if the firmware is not put

Since 2021, Xiaomi has implemented an anti-rollback mechanism that blocks installing firmware older than the one already on the device, to prevent it from downgrading to vulnerable versions, but sometimes anti-rollback also interferes with switching to Chinese firmware if its version is older than the global one.

There are several ways to get around this limitation:

• 🔄 Use the new version of the firmware: Download the latest MIUI China Stable for your model. Check the build date - it should be newer than the current firmware.
• 🛠️ Apply an anti-rollback patch (for advanced users): Download a modified anti.rb file for your model (see for the XDA or 4PDA). Replace the original file in the firmware folder. Sweep the device through the Mi Flash Tool with the check disabled (flash_all_except_storage.bat).
• 📱 Use it. EDL-Mode (extreme): Requires an authorized Xiaomi account and a special cable, allows you to flash the device even with a locked bootloader. Risky - if you make a mistake, the device can turn into a brick".

If you are not sure about your skills, you should wait for the release of the new version of Chinese firmware or ask for help on profile forums. Remember: improper bypassing the anti-rollback can lead to the loss of IMEI or lock the device.

To check the current version of the antirollback, use the command in fastboot:

fastboot getvar anti

If the answer has a line anti:5, then the device is active protection level 5, and downgrade is impossible without a patch.

Setup of the system after installing Chinese firmware

Once you have a successful firmware, you have to reconfigure the device, and the Chinese version of MIUI has a number of features that might not be obvious to global firmware users.

Here's what you need to do first:

• 🔧 Install Google Play Services: Download the Google Installer package from the official website or APKMirror. APK Follow the instructions (permission to install from unknown sources is required).

It is also recommended that:

• 🛡️ Install Magisk to obtain root rights (if necessary).
• 🎨 Download themes and fonts from MIUI Theme Store (in Chinese version there are more of them).
• 🔋 Disable battery optimization for frequently used applications (Settings) → Battery → Optimizing the battery).

If NFC is missing after firmware or Google Pay is not working, it is due to Google's lack of certification for Chinese devices.

• Install the Magisk Universal SafetyNet Fix module.
• Or run a custom kernel with Google Pay support (like PixelExperience).

Frequent mistakes and their solutions

Even with strict adherence to the instructions, problems can occur, and here are the most common mistakes and ways to correct them:

If your device is stuck on the MI (bootloop) logo, try the following steps:

1. Press Volume Up + Power for 10 seconds to enter Recovery.
2. Select Wipe Data → Wipe All Data (Settings Reset).
3. Restart the device. If the problem persists, re-sweep through fastboot.

If the fingerprint sensor or camera stopped working after firmware, it may be due to driver incompatibility.

• Install firmware for another version (e.g. Developer instead of Stable).
• Sweep separately the persist and vendor sections from the global firmware.
