How to Install Firmware on Xiaomi: The Complete 2026 Guide

Why You Should Update Your Firmware on Xiaomi and When You Really Need It

Firmware is the software that controls your Xiaomi device, and its version is dependent on performance, stability, available features, and even security. However, it is not always a mandatory procedure to update your firmware, for example, if your Redmi Note 12 is running smoothly and the new MIUI version brings only cosmetic changes, you should not risk it.

When is firmware really needed? First, if the device is stuck on the Mi logo, not turning on or rebooting in cycles, it is a clear sign of corrupted software. Second, if you want to switch from the Chinese version of MIUI to the Global ROM for full support of Russian language and Google services. Third, the update is required to fix critical security vulnerabilities that the manufacturer closes in new versions.

But remember, a bad firmware can turn a smartphone into a brick, especially with bootloader models like the Xiaomi 13 Pro or POCO F5. Before you start, assess the risks and prepare properly.

Preparation for firmware: what to do before the start

The first and most important step is to save data. Firmware, especially through Fastboot, almost always results in a complete device reset. Use Mi Cloud, Google Drive or local copying on your PC to back up:

• 📱 Contacts (export in.vcf format)
• 📸 Photos and videos (check folders) DCIM and Pictures)
• 📄 Documents and downloads (especially files from Download)
• 🔑 Passwords and application data (use Titanium Backup for rooted devices)

Next, make sure you have:

• 🔋 Battery charge at least 60% (better 100%) Interrupting the process due to discharge is a sure way to kill the device.
• 💻 Windows computer 10/11 (For Fastboot and Mi Flash Tool. Mac/Linux Possible problems with drivers.
• 🔌 Original. USB-cable (cheap cables can interrupt the connection).
• 📥 The right firmware for your model:

⚠️ Note: Firmware from unofficial sites (for example, 4PDA) They may contain modified cores or spyware. If you are not an expert, avoid custom builds (customs). ROM).

Unlocking bootloader on Xiaomi: without it can not do

Most Xiaomi devices come with a locked bootloader, which means you won’t be able to install firmware through Fastboot or EDL-mode until you unlock it. Except for the update via Recovery (if the firmware is signed for your model).

The unlocking process is officially supported by Xiaomi, but has limitations:

• 🔐 Requires linking your Mi Account to your device.
• ⏳ Waiting for permission can take anywhere from 72 hours to 30 days (depending on the model).
• 📱 On some devices (e.g. Xiaomi) 12T) Unlocking resets all data.

Instructions for unlocking:

1. Activate Developer Options: Go to Settings → About Phone → MIUI version and press 7 times.
2. Enable USB Debugging and OEM Unlocking in Settings → More → For Developers.
3. Download the Mi Unlock Tool and log in to your Mi Account.
4. Connect the device in Fastboot mode (clip Volume down + Power when the phone is off).
5. Run the Mi Unlock Tool and follow the instructions. If you receive a waiting message, wait until the time is set.

⚠️ Note: Once the bootloader is unlocked, the Xiaomi device may lose its warranty.In addition, some banking applications (such as Sberbank Online) will cease to work due to the lack of SafetyNet certification.

How to install firmware: which one to choose?

There are three main methods of firmware Xiaomi devices, each with its pros and cons:

Let’s look at each method in more detail.

Method 1: Firmware through Recovery (without data loss)

This is the safest way, but it is only suitable for installing official MIUI updates via OTA (over the air) or manually. Importantly, the firmware version must match the current one (for example, update MIUI 14.0.3 to 14.0.5, but not to 15).

Instructions:

1. Download the firmware in.zip format for your model (for example, fw_redmi_note12_global_14.0.5.0.zip).
2. Rename the file to update.zip and place it in the root of internal memory.
3. Go to Settings → About the phone → System update.
4. Click on the three dots in the upper right corner and select Select the firmware file.
5. Please specify the path to update.zip and confirm the installation.

⚠️ Warning: If after the reboot the device got stuck on the Mi logo, try resetting the cache: press Volume up + Meals, select Wipe Cache.

💡

If Recovery doesn't have a "Select firmware file" option, your model only supports air updates, in which case use Fastboot or wait for OTA.

Method 2: Fastboot Firmware (complete reinstallation)

This method allows you to install any official firmware, including changing the region (for example, from China ROM to Global).

Step-by-step:

1. Download Fastboot firmware for your model (.tgz or.zip file).
2. Unpack the archive in a folder on your PC (e.g., C:\MiFlash\rom).
3. Download and install the Mi Flash Tool.
4. Transfer the device to Fastboot mode (clip Volume Down + Power).
5. Connect your smartphone to your PC and start the Mi Flash Tool.
6. Click Select, specify the path to the firmware folder, then Refresh (the device should appear).
7. Select Clean All (full reset) or Clean All and Lock (reset + lock bootloader).
8. Press Flash and wait until it is completed (5-10 minutes).

If the Mi Flash Tool is 0x80070002 error, check:

• 🔌 Connection to USB (Try another port or cable).
• 🖥️ Drivers installed ADB/Fastboot (Download Platform Tools).
• 📁 The path to the firmware does not contain Cyrillic symbols.

Method 3: Firmware through EDL (for “bricks”)

EDL (Emergency Download Mode, aka 9008) is used when a device is not enabled or detected in Fastboot.This method requires an authorized Xiaomi account and special software, such as Mi Flash Pro or QFil.

Instructions:

1. Download the firmware for EDL (usually a.mbn or.elf file).
2. Transfer the device to EDL mode: For working devices: adb reboot edl For “bricks”: close the test points on the board (requires disassembly).

⚠️ Attention: Firmware through EDL Unauthorized can lead to blocking IMEI. On new devices (e.g. Xiaomi 14), this method only works with official permission from Xiaomi.

Frequent Firmware Mistakes and How to Avoid Them

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

If the device doesn’t turn on after firmware or gives a No command error in Recovery, try:

• 🔄 Repeat the firmware through Fastboot with a full reset (Clean all).
• 📥 Install an older version MIUI, then upgrade to a new.
• 🔧 Check the integrity of the downloaded firmware (compare hash) MD5 formal).

💡

If the IMEI is missing or the network is not working, then the firmware was for another model or damaged by NVRAM. You can restore the IMEI through the engineering menu (#4636##) or specialized utilities (for example, SN Write Tool).

Custom ROM firmware: LineageOS, Pixel Experience and others

If you don't like standard MIUI, you can install custom firmware, such as LineageOS, Pixel Experience or ArrowOS.

• 🚀 Higher performance (no extra software from Xiaomi).
• 🆕 Update Android Updates (Even for Older Devices).
• 🔓 More opportunities for customization.

There are, however, downsides:

• ⚠️ Loss of guarantee.
• 📵 Possible problems with the camera, NFC or wireless modules.
• 🔒 Some banking apps will not work due to the lack of SafetyNet.

Instructions for installing LineageOS:

1. Unlock the bootloader (see section above).
2. Install custom Recovery (e.g. TWRP): fastboot flash recovery twrp.img fastboot boot twrp.img
3. Download firmware (.zip) and GApps (Google services) from the LineageOS website.
4. In TWRP, run Wipe → Advanced Wipe (mark Dalvik, Cache, System, Data).
5. Install the firmware, then GApps, and restart.

⚠️ Note: Castom firmware does not support Widevine L1, That's why Netflix, Disney.+ Other services will work in low resolution (480p).
