How to install another firmware on a Xiaomi smartphone: a complete guide with risks and life hacks

Reflashing Xiaomi’s smartphone is a process that can both unlock the device’s hidden potential and turn it into a brick if you approach it without preparation. → The phone. → Updating the system, installing custom firmware requires unlocking the bootloader, working with fastboot or recovery, and understanding the risks. This guide will help you understand how to safely change firmware to Xiaomi, whether it is switching from a global version to a European one, installing a new one. MIUI without advertising or complete abandonment of the company shell in favor of AOSP (LineageOS or Pixel Experience).

It is important to understand that the procedure is different for different models (Redmi Note 12 Pro).+, POCO F5, Xiaomi 13 Ultra) and firmware types. TWRP, And somewhere you will have to use the official Mi Flash Tool with authorization in the Xiaomi account. We will analyze all scenarios – from preparation to recovery after a failed firmware, and also answer questions why the device may not turn on after an update or how to return the stock firmware if something went wrong.

1.Why to change firmware to Xiaomi: pros and hidden risks

Before you start flashing, evaluate what you'll get and what you might lose.

• 🚀 Performance: custom firmware (e.g. Pixel Experience) is often devoid of Xiaomi’s excess software, which speeds up work even on weak chips (Snapdragon). 6xx or Helio Gxx).
• 🔓 Freedom: the ability to install root, remove system applications (com.miui.analytics), customize the interface for yourself.
• 🌍 Regional chips: transition from the Chinese version (CN) Global (Global) or European (European (EEA) Support for Google Services and local services LTE-range.
• 🛡️ Security: Current security patches in AOSP-scaling (while the MIUI sometimes delaying updates).

But there is a downside:

• ⚠️ Loss of warranty: Unlocking the bootloader will officially void the Xiaomi warranty (even if you return the stock firmware).
• 💥 "Brick Device: An incorrectly selected firmware or interrupted process can make the phone unusable (solved via a EDL-regime, but not always).
• 📵 Module problems: cameras, NFC or sensors may not work properly on unofficial firmware (especially relevant for flagships like Xiaomi 14).
• 🔋 Deterioration of autonomy: optimization of energy consumption in the MIUI Often better than in custom assemblies.

⚠️ Note: On devices with MediaTek chip (e.g. Redmi) 12C or POCO M6 Pro) unlocking the bootloader may not be possible without authorization through the device-associated Mi Account. Check your model support on the forum XDA Developers before the start of the procedure.

2. firmware preparation: what to do before unlocking the bootloader

The first and most important step is preparation, and without it, the risk of turning a phone into a brick increases dramatically.

Backup all data (photos, contacts, SMS)

Check the device model in Settings → About the phone → Model

Download the correct firmware version (corresponds to the device code!)

Install ADB/Fastboot and Mi Flash Tool drivers on PC

Charge your phone at least 60%

Disable Mi Account and Find My Device (if tied)

Prepare. OTG-cable (for firmware through TWRP)

-->

Data backup: The firmware erases everything from internal memory (including folders) DCIM, Downloads and application settings. Use:

• 📱 Local backup: Settings → Additionally. → Backup and reset → Local backup (saves the backup) SMS, calls, Wi-Fi settings).
• ☁️ Cloud: Google Drive (contacts, calendar), Mi Cloud (photos, notes) or Swift Backup (data applications, requires root).
• 💻 Manual copying: connect your phone to your PC in File Transfer mode and copy Internal Storage folders to your hard drive.

Definition of model and firmware version. Each Xiaomi model has a unique code (for example, raphael for Redmi). K20 Pro or alioth for POCO F3). You can recognize him:

• In settings: Settings → The phone. → Version. MIUI (for example, V14.0.4.0.TKHCNXM — Chinese version for Redmi K30 Pro).
• Adb shell getprop ro.product.device (indicates the device code, for example, lmi for the device). POCO F2 Pro).

⚠️ Note: If your device supports Dynamic Partition (e.g. Xiaomi) 12T Or later, firmware via fastboot may require additional commands to mark up partitions. Ignoring this step will lead to a critical partition missing error.

3. Unlock the bootloader: the official way from Xiaomi

Without an unlocked bootloader, custom firmware cannot be installed. Xiaomi allows you to do this legally, but with restrictions:

1. Make sure that the phone has an authorized Xiaomi account, and in the settings disabled Find My Device and Mi Cloud Sync. Account must be older than 30 days (for new devices).

The unlocking process takes up to 72 hours (on new devices), and once completed successfully, you'll see a message called Unlocked successfully, and you can now flash custom recovery or install firmware through fastboot.

1. Use another. USB-cable (original from Xiaomi).

2. disable the antivirus on the PC (it can block drivers).

3.Reboot the phone to fastboot and try again.-->

4. Selection of firmware: MIUI vs AOSP, stable vs weekly

Firmware for Xiaomi is divided into two camps: official (from Xiaomi) and custom (from the community).

Official MIUI firmware

• 🌐 Global Stable: For the international market, with Google Services, updates once in a while 2-3 month.
• 🇪🇺 EEA (Europe: as Global, but without advertising and with VoLTE support for European operators.
• 🇨🇳 China Stable: No Google, but with maximum optimization (suitable for power users).
• 🔄 Weekly/Beta: weekly builds with new features, but bugs are possible (for example, MIUI 15 Beta for Xiaomi 14).

Custom firmware

• 📱 Xiaomi.eu: MIUI without advertising, with advanced settings, but without official support.
• 🤖 AOSP (LineageOS, Pixel Experience, ArrowOS: pure Android without shell MIUI, There may be problems with the camera or NFC.
• ⚡ Custom Kernels: Modified core firmware for overclocking or improving autonomy (e.g. FrancoKernel for the POCO F4).

Critical information: Snapdragon and MediaTek firmware are not interchangeable! Install Snapdragon firmware on a MediaTek device (e.g. Redmi Note 12) 4G instead 5G) This will cause the communication module to fail.

Where do I download firmware?

• 🔗 Official: en.miui.com (select by device code!).
• 🔗 Xiaomi.eu: Xiaomi.eu (weekly and stable builds).
• 🔗 AOSP: XDA Developers (Search for the theme of your model).

5. Firmware methods: fastboot, recovery, EDL

The choice of method depends on the type of firmware and the state of the device. Let's consider three main ways:

1. Firmware via fastboot (for official and custom firmware)

Suitable for installation MIUI or Xiaomi.eu with unlocked bootloader:

1. Download the firmware in.tgz format and unpack it into a folder with the Mi Flash Tool.
2. Turn off your phone and press the power. + Vol Down for fastboot login.
3. Connect the device to your PC and run the Mi Flash Tool. Select the firmware folder.
4. Press Refresh, then Flash. To clean it completely, choose clean all (washes everything, including internal memory!).

2. Firmware through TWRP (custom-built)

TWRP — It's custom recovery, which allows you to install zip firmware and make backups:

1. Install. TWRP Fastboot: Fastboot Flash Recovery twrp-3.7.0_*.img fastboot boot twrp-3.7.0_*.img
2. V TWRP run the Wipe → Format Data (required for the AOSP!).
3. Transfer the firmware (.zip) to your phone via MTP or OTG.
4. Press Install, select a firmware file and confirm the installation.

⚠️ Note: On some devices (Xiaomi) 12S Ultra, POCO F4 GT) TWRP does not support encryption FBE (If after firmware, the phone asks for a password and you did not set it, you will need to format data into TWRP via Wipe → Format Data → yes.

3. Firmware through EDL (Emergency mode)

Used if the phone is not turned on (brick) or the bootloader is blocked. Requires an authorized Xiaomi account and a special cable:

1. Download Mi Flash Pro and firmware in.mbn format.
2. Put the phone in. EDL-Mode (press Vol Up) + Vol Down and plug in USB).
3. In Mi Flash Pro, select firmware and press Flash.

💡

Firmware through EDL — The last chance to save the "brick" device, but requires authorization in Mi Account with a connection to the device. SLA Auth Error.

6. Common mistakes and how to avoid them

Even experienced users face firmware problems. Let's take a look at the most common ones:

This package is for "xxx" devices; this is a "yyy." So you're trying to flash the firmware for a different model. 5G (veux is not suitable for the Redmi Note 11 Pro 4G (peux) Decision:

• Check the device code with the command fastboot getvar product.
• Download firmware specifically for your code (e.g., vili for Xiaomi) 11T Pro).

The phone is not defined in fastboot. The problem may be the drivers or the cable:

• 🔌 Use the original Xiaomi cable (cheap cables often don’t transfer data to fastboot).
• 🖥️ Install Qualcomm drivers HS-USB QDLoader 9008 (for the EDL) Google USB Driver (for fastboot).
• 🔄 Try another one. USB-port (preferably) USB 2.0 on the back of the PC).

7.Recovery after failed firmware

If the phone doesn't turn on, gets stuck on the screensaver or makes errors, don't panic. In 90% of cases, the device can be brought back to life.

Scenario 1: The phone is stuck on the logo MI or

Reason: Incompatible firmware or incomplete Wipe.

1. Hold the Power. + Vol Up for recovery entry (if installed) TWRP).
2. Run Wipe → Format Data (this will delete everything, including internal memory!).
3. If it doesn't work, run the stock firmware through fastboot.

Scenario 2: Phone does not respond to buttons (full breech)

Cause: The boot boot boot boot or partition is damaged.

1. Connect the phone to your PC and check if it is defined as Qualcomm HS-USB QDLoader 9008 (EDL mode).
2. Download the firmware in.mbn format and run through Mi Flash Pro.
3. If EDL not available, contact the service center - you will need soldering equipment for recovery.

⚠️ Note: On devices with MediaTek chip (e.g. Redmi) 10C or POCO M5) recovery EDL Often requires an authorization file (auth.ini) that can only be obtained from official Xiaomi partners (cost) ~$20–$50).
