Xiaomi smartphones with factory Chinese firmware often come with limitations: no Google Play, no Russian language in the system, and some services (for example, Google Mobile Services) are malfunctioning. The transition to global firmware solves these problems, but the process requires care - an error at any stage can lead to a "brick" of the device. In this article, we will analyze all the ways to replace the firmware (via Fastboot, Recovery and MIUI bootloader), the nuances of unlocking the bootloader and typical errors with solutions.
Many users are afraid to stitch the smartphone themselves for fear of losing warranty or data. In fact, unlocking the bootloader through the official Mi Unlock tool does not void the hardware warranty (software only), and backing up through Mi Cloud or TWRP saves 90% of user data.
Before you start, make sure your Xiaomi model supports global firmware.Some devices (e.g. Redmi) K60 Ultra or POCO F6 Pros are originally only available for the Chinese market and may require a converted firmware from third-party developers. XDA Developers or 4PDA — It'll save you time and nerves.
1.Preparation: What to do before the firmware
The first step is to back up your data, and even if you plan on using the non-reset (OTA) update method, you still have the risk of losing your files.
- 📱 Contact and SMS (via Mi Cloud or Google Contacts)
- 📷 Photos and videos (copy to PC or cloud)
- 🔑 Passwords from apps (use Google Password Manager or KeePass)
- 🎮 Game Preservation (via Helium or manual export)
Next, check the current firmware version and device model. Go to Settings → About the phone. Write down:
- Device model (e.g. Redmi Note 12 Pro+ 5G)
- Codename (e.g. ruby for Redmi Note 10 Pro)
- MIUI version (e.g. MIUI 14.0.3.0.SKFCNXM)
The code name can be specified on the Xiaomi Firmware Updater website – this is critical for choosing the right firmware.
It is equally important to prepare the PC:
- 🖥️ Install Mi Flash Tool (for Fastboot firmware)
- 🔌 Download Qualcomm or MediaTek drivers (depending on the processor)
- 🔗 Connect your smartphone to your PC with the original cable (do not use cheap analogues!)
⚠️ Note: If your Xiaomi is blocked by an operator (e.g. China Telecom), unlocking the bootloader may not work. EDL-Mode and authorized Xiaomi account, which is difficult to implement independently.
2 Unlock the bootloader: the official method
Without unlocking the bootloader, you can’t install global firmware. Xiaomi allows you to do this legally through the Mi Unlock tool, but with restrictions:

3. firmware selection: global vs. converted
There are two types of firmware to replace the Chinese version:
- Official Global ROM – supported by Xiaomi, Air Updated (OTA), but may not be suitable for some Chinese models.
- China to Global is a repackaged Chinese firmware with Google Apps and a multilingual interface, suitable for devices without an official global version.
Where to download:
| Source | Type of firmware | Pluses | Cons |
|---|---|---|---|
| Official MIUI website | Global ROM | Stability, OTA-update | Not for all models. |
| Xiaomi Firmware Updater | Global/China | Current versions, archive | No converted firmware |
| 4PDA | Converted | For informal models | Risk of instability |
How to choose the correct version:
- 🔍 Check the device codename (e.g. rubens for Redmi Note 12 Pro) 5G).
- 📌 Download firmware marked Fastboot (for installation via Mi Flash) or Recovery (for installation via TWRP).
- ⚠️ Avoid firmware marked "Stable Beta" - they may contain critical bugs.
💡
If you are not sure about the choice of firmware, check it for compatibility through XiaomiTool V2 – the tool will automatically select the correct version.
4. Installation of global firmware through Fastboot
This is the most reliable method, but it completely resets the device.
- 🖥️ Windows PC (for Mi Flash Tool)
- 🔌 Original. USB-cable

5. Alternative methods: Recovery and OTA
If Fastboot is not suitable (for example, due to a blocked bootloader), you can use:
- 🔄 Update via Recovery – suitable for firmware in.zip format (e.g., converted). TWRP or stock Recovery with support for installing updates.
- 🌐 OTA-Update – if your Chinese firmware supports the transition to global through Settings → System updates. Rarely works for new models.
