The move to Xiaomi’s global firmware is a popular solution among users who want to get rid of the limitations of Chinese versions of MIUI (no Google services, censorship, local features) or get more features than European builds. However, the process requires caution: wrong actions can turn a smartphone into a “brick”, deprive warranties or cause problems with the operation of communication modules.
In this guide, we will discuss all the stages of the transition from unlocking the bootloader to installing global firmware, including nuances for different models (Redmi Note 12 Pro+, POCO F5, Xiaomi 13T, etc.). We will pay special attention to the risks of losing IMEI and methods of preventing them, as this is the most common problem with incorrect firmware, and you will find relevant links to official tools and alternative solutions for devices with a locked bootloader.
Why are users switching to Xiaomi’s global firmware?
The main reason is the lack of Google services in the Chinese versions of MIUI. Without them, you can not fully use the Play Market, Gmail, YouTube and other applications, even if you install them manually through APK, some functions (such as push notifications) will not work.
Other strong arguments:
- 🌍 Localization: Global firmware supports Russian and is adapted to regional standards (time zone, date formats, keyboard).
- 📡 Support 4G/5G: Chinese firmware often turns off frequencies used in Europe and Russia, leading to a poor signal.
- 🔄 Regular updates: Global versions MIUI Get security patches and new features faster than local builds.
- 🛡️ Less embedded software: Global firmware has fewer unnecessary Chinese apps (e.g. Mi Pay, Mi Video with local content).
However, there are also disadvantages: some functions (for example, IR-The remote or camera modes may work differently or not, and global firmware sometimes gets updates later than Chinese ones, depending on Xiaomi’s policy.
Preparation for the transition: what to do before the firmware
Before you start changing the firmware, be sure to follow these steps:
Make a backup copy of data (photos, contacts, messages)|Check the model and current version MIUI In Settings → The phone.|Make sure the battery is charged > 60%|Download the correct firmware version for your model|Prepare the cable. USB and PC with installed drivers-->
Pay special attention to backup. When you change the firmware, all the data on the device will be erased! Use Mi Cloud or third-party tools like Titanium Backup.
- 📞 IMEI (06# - useful if the network disappears after the firmware).
- 📁 folder MIUI on the internal drive (there are stored camera settings and system data).
- 🔑 Logins and passwords from Mi and Google.
Check your model’s compatibility with global firmware on the Xiaomi Firmware Download site. For example, the Redmi Note 11 Pro+ 5G has separate builds for China (vili) and the global market (veux). Installing improper firmware will lead to idle modules (camera, NFC, sensors).
⚠️ Note: If your device is purchased in China and has a locked bootloader linked to your Mi Account, unlocking can take up to 720 hours (30 days) of waiting after you have attached your account.
Unlocking the loader: step-by-step instructions
Without the bootloader, you can't install the global firmware.
- Linking your Mi Account to your device: Go to Settings → Mi → Mi Cloud Account and log in. Make sure the device is linked to your account (check Settings → About Phone → All Settings → Mi Account Status).
- Request permission to unlock: Download the official Mi Unlock Tool app from Xiaomi (link: en.miui.com/unlock). Launch it on your PC, log in to the same Mi Account and follow the instructions. The device must be in Fastboot mode (click Loudness down + Power when the phone is off).
- Waiting for confirmation: Once successfully linked, the countdown will begin (usually 168 hours, but for new accounts it can be 720 hours). Status can be checked in the Mi Unlock Tool. Attempts to unlock before the timer expire will count down!
When the timer is zero, plug the phone into Fastboot mode and press Unlock into the Mi Unlock Tool, which takes a few seconds to unlock, and the device automatically resets to factory settings.
What if the Mi Unlock Tool can’t see the device?
Selection of global firmware: stable vs. developer
Xiaomi offers two types of global firmware:
| Type of firmware | Advantages | Deficiencies | Who's right for? |
|---|---|---|---|
| Stable (Stable) | Maximum reliability, rare bugs, optimized power consumption | Updates are less frequent, new features appear with a delay | Users who are interested in the stability of work |
| Developer (Developer) | Weekly updates, early access to new features | Possible bugs, fast battery discharge, unstable operation of some modules | Enthusiasts who are ready to test new software |
| Custom ROM (Custom ROM) | Advanced settings, no Bloatware, alternative shells (e.g. Pixel Experience) | Loss of warranty, possible iron problems (camera, sensors) | Advanced users with firmware experience |
For most users, stable global firmware is the best choice, and you can download it on the official website:
- 🔗 Official portal MIUI (Choose the Stable section → Global).
- 🔗 Xiaomi Firmware Updater (alternative source with archived versions).
Note the code name of the device (e.g., toco for Xiaomi 11 Ultra). It is indicated in the name of the firmware file. You can find it in Settings → About Phone → All settings → Model or through the command in ADB:
adb shell getprop ro.product.devicecertutil -hashfile name file.zip MD5This will protect against fake firmware with malware.-->
Installation of global firmware: 3 proven methods
Once you unlock the bootloader and download the correct firmware, you can start installing it, and let's look at three ways, from the simplest to the most reliable.
Method 1: Through built-in recovery (TWRP not required)
Suitable for devices with an already unlocked bootloader and official global firmware in.zip format.
- Copy the firmware file into the root of the phone’s internal memory.
- Go to Settings → About the phone → System update.
- Click on the three dots in the upper right corner → Select a firmware file.
- Specify the downloaded file and confirm the installation.
The device will reboot and install the firmware automatically, which is the safest method, but doesn’t work on all models (for example, a POCO X3 Pro might require a TWRP).
Method 2: Fastboot (official method)
Used to "clean" install firmware through a PC, you'll need a firmware archive in.tgz format (unpack it before using it).
- Install the Mi Flash Tool (download: xiaomiflashtool.com).
- Transfer the phone to Fastboot mode (clip Volume Down + Power).
- Connect the device to your PC and start the Mi Flash Tool.
- Press Select, specify the folder with unpacked firmware.
- At the bottom, select Clean all (full reset) or Clean all and lock (reset + lock the bootloader after firmware).
- Press Flash and wait until it is completed (5-10 minutes).
Method 3: Through TWRP (for power users)
This method allows you to install custom or modified firmware, as well as make a backup before installation.
- Download and install TWRP Recovery for your model (search at twrp.me).
- Put your phone in Fastboot mode and run the TWRP command: fastboot flash recovery twrp.img fastboot boot twrp.img
- In TWRP, run Wipe → Advanced Wipe and mark Dalvik, Cache, Data, System.
- Install the firmware through Install, then Reboot System.
⚠️ Attention: When in use TWRP on some models (Xiaomi) 12T, Redmi K50) It can trigger an anti-rollback that locks the device when you try to install an old firmware version. Always check the version. MIUI and Android before the firmware!
Solving problems after firmware
Even if you install global firmware properly, there can be problems, and let's look at the most common ones and how to fix them.
1. no network (IMEI missing or undetected)
This is the most critical problem that arises from damage to the modem or nvram partition.
- 🔧 Recovery IMEI through SN Write Tool (requires nvram backup or original) IMEI).
- 🔄 Fastboot flashing with a clean all and lock check (sometimes helps to return the network).
2 Google Services or Play Market are not working
If Google apps are missing or fly out after firmware:
- 📥 Install Google Installer from APKCombo.
- 🔄 Perform reset through Settings → Additionally. → Resetting settings.
- 🛠️ Please use Google Apps (Gapps) through TWRP (Download: OpenGApps).
3. Fast battery discharge
Once the firmware is changed, the system can index the data and optimize the work, which temporarily increases battery consumption.
- 🔋 Calibrate the battery: discharge the phone to 0%, then charge to 100% without interruptions.
- ⚙️ Turn off background activity of unnecessary apps in Settings → Battery → Optimizing the battery.
- 🔄 Reset the battery settings through TWRP (wipe → Battery Stats).
💡
If the phone doesn't turn on or hangs on the MI logo after firmware, try flashing it through the Fastboot with the Clean all tick. If that doesn't help, the boot or recovery section may be damaged, and you'll need a full flash flash flashing through the Mi Flash Tool with a choice of Clean all and lock option.
