What firmware to put on Xiaomi: official and alternative options in 2026

Choosing firmware for Xiaomi smartphone is always a compromise between stability, functionality and performance. On the one hand, the official MIUI offers maximum compatibility with hardware and access to branded chips (like Game Turbo or Second Space), on the other hand, custom firmware like LineageOS or Pixel Experience eliminates advertising, bloated software and gives a clean Android with fast updates.

But how do you make the wrong choice? Because the wrong firmware can lead to loss of warranty, broken modules (NFC, camera, sensors), or even "bricking" the device. In this guide, we will analyze all the current options for different scenarios, from official global builds to niche customizations for enthusiasts, and also tell you how to check compatibility and avoid typical errors when reflashing.

1. Official firmware Xiaomi: MIUI in different versions

Xiaomi’s official software is always the safest choice, especially for beginners, and it guarantees all sensors, full-resolution cameras, and support for services like Mi Cloud or Mi Pay. But even here, there are nuances: MIUIs come in three types, and they’re easy to confuse.

Three key versions of MIUI:

• 📱 China Stable (CN) — Chinese firmware with maximum functionality, but without Google Services and with reference to Chinese services, suitable for advanced users who are ready to install GApps manually.
• 🌍 Global Stable (MI) — international version with Google services pre-installed, but often cropped in features (e.g. no those from a Chinese store).
• 🧪 Beta/Developer (Weekly builds with new features but possible bugs, suitable for testing, but not for everyday use.

Important: even within the same MIUI version, there may be subspecies. For example, Global for Redmi Note 12 Pro+ and Global for Xiaomi 13 Ultra will differ in driver set and optimization. Check the exact model of your device in Settings → About Phone → Model.

2.Castom firmware: when to switch to AOSP

If you’re annoyed by MIUI ads, slow updates, or redundant features, custom firmware based on the Android Open Source Project (AOSP) can be a lifeline.

• ⚡ Pure Android without Bloatware (preinstalled unnecessary apps).
• 🔄 Quick security updates (monthly, unlike the one you get) MIUI, where you wait six months).
• 🎨 Ability to fine-tune the interface (for example, changing fonts, animations, statusbar).
• 🛡️ No telemetry collection (unlike the MIUI, sends data to China).

There are downsides, though: some custom phones may not support the Widevine L1 (Netflix has no HD), and Xiaomi's budget models (like the Redmi 9A) often break the camera or NFC. Before you switch, check compatibility on the XDA Developers or 4PDA forums.

3. Top.-5 Custom firmware for Xiaomi: comparison and features

The choice of custom firmware depends on your priorities: someone needs maximum FPS in games, someone needs long-term autonomy, and someone needs support for all sensors. We selected the 5 most popular options with their pros and cons.

⚠️ Note: On new flagships Xiaomi (for example, Xiaomi 14 or Redmi) K70 Pro) custom firmware is often broken 5G-modem or Ultra-Wideband (UWB). Before installing, check the reviews on XDA for your particular model!

4. How to check firmware compatibility with your Xiaomi

Installing incompatible firmware is a surefire way to get a brick. To avoid this, follow the checklist:

Make sure the firmware name matches the code name of your device (e.g., raphael for Redmi K20 Pro)

Check the bootloader version (fastboot getvar anti – must match the firmware requirements)

Check the list of supported features (camera, NFC, VoLTE) on the firmware page

Download firmware only from official sources (XDA, Telegram-channel developer, GitHub)

-->

The code name of the device can be found:

• 📱 In settings: Settings → The phone. → Version. MIUI → Code name (e.g. alioth for Poco) F3).
• 💻 Through ADB: Connect your phone to your PC and execute the command: adb shell getprop ro.product.device

If your device isn’t officially supported but there’s an unofficial port, be prepared for bugs. On the Redmi Note 10 Pro (sweet), for example, the unofficial LineageOS may not support 90Hz in some applications.

💡

Before you run the firmware, save the persist.img file from the current firmware, which contains the calibration of the sensors, and its loss can lead to a gyroscope or compass that is not working.

5. Step-by-step instructions: how to flash Xiaomi without errors

The firmware process depends on the type of firmware (official or custom) and the state of the bootloader. We will look at the universal method through Fastboot, which works for most models.

What you'll need:

• 🖥️ Computer with Windows/Linux and installed drivers ADB/Fastboot.
• 🔌 Cable USB (preferably original to avoid communication interruptions).
• 📁 Firmware in.tgz or.zip format (for custom – with GApps, if you need Google services).
• 🔓 Unlocked bootloader (for custom firmware).

Steps of firmware through Fastboot:

1. Unpack the firmware in the folder from fastboot.
2. Turn your phone into Fastboot mode: Turn off the device, then press Power + Vol Down.
3. Connect your phone to your PC and check the connection with the command: fastboot devices must display the serial number of the device.
4. Run the firmware script: fastboot update name file.zip Or for official firmware Xiaomi: fastboot flash all (if the firmware is in.tgz format).
5. Wait until the cable is completed (don't turn off!) the phone will reboot automatically.

⚠️ Note: Some models (e.g. Xiaomi) 12T) When you run through Fastboot, you can run an anti-rollback, which is an anti-rollback protection. If you see an anti-version down error, run through the newer official firmware first, and then caste it.

6. Frequent mistakes and how to avoid them

Even experienced users sometimes experience firmware problems, and here are the most common bugs and solutions:

• 🔴 Error "This package is for... but this is a..." Reason: The firmware is not suitable for your model or region. Solution: Check the code name of the device and download the correct version.
• 🔴 Bootloop (cyclic reboot) Cause: Kernel incompatibility or no vendor files. Solution: Squeeze vendor.img and boot.img separately via Fastboot.
• 🔴 Touchscreen does not work after firmware Reason: Wrong version dtbo.img. Solution: Find the right dtbo for your model 4PDA.
• 🔴 No SIM or no network is available Cause: not to flash modem or EFS-Solution: Restore EFS from the backup or swipe the official modem.

If the phone doesn’t turn on after firmware (black screen, vibration without booting), try:

1. Hold the Power + Vol Up for 10-15 seconds for forced reboot.
2. Connect to your PC and check if the device is detected in Fastboot or EDL.
3. If your phone is in EDL (9008 mode), use the Mi Flash Tool to recover.

💡

Before any firmware, make a backup section EFS (IMEI, MAC-Addresses and persists (calibration of sensors) can make the phone unusable for calls or networking!

7 How to return the official firmware if something went wrong

If custom firmware is unstable or you need a warranty, you can always return to the official MIUI.

Method 1: Fastboot (recommended)

• Download the official firmware for your model from en.miui.com/a-234.html.
• Unpack the archive and launch the script flash_all.bat (Windows or flash_all.sh (Linux/Mac).
• Wait until it is finished, the phone will automatically reboot to MIUI.

Method 2: Recovery (if the Fastboot is not working)

• Download firmware in.zip format (for example, MIUI Global Stable).
• Rename the file to update.zip and place it in the root of internal memory.
• Press Power + Vol Up to enter Recovery.
• Select Install update.zip and confirm the installation.

⚠️ Note: Some models (e.g. Xiaomi) 13T) If the phone asks for Mi Account authorization and you don’t remember it, use the Mi Account Unlock Tool (but this violates Xiaomi rules and can block the device!).
