How to download firmware on the Xiaomi smartphone: official and alternative ways

Xiaomi’s smartphone firmware is a process that can bring a device back to life or turn it into a brick if you approach it without preparation. Unlike standard “over the air” updates, manually installing firmware requires an understanding of nuances: From choosing the right version of the software to unlocking the bootloader, this guide covers all current methods of downloading firmware on Xiaomi, including official ones. MIUI-Updates, custom builds like LineageOS or Pixel Experience, and recovery via Fastboot and Recovery.

Importantly, the firmware procedure is different for devices with locked and unlocked bootloader. For example, new models Xiaomi 13/14 series or Redmi Note 12 require mandatory unlocking through Mi Unlock Tool, whereas on older devices (until 2020) sometimes enough Recovery mode. We will analyze both scenarios, and also tell you how to avoid typical errors like Error: Critical Partition or hanging on the Mi logo.

If you’ve never flashed a smartphone before, start with the official methods — they’re as safe as possible and they don’t take away warranties. For enthusiasts who want to install custom software, we’ll give you step-by-step instructions tailored to Xiaomi’s features, including working with ADB, Fastboot, and alternative TWRP-type recoveries.

1. Firmware Preparation: What to Do Before Starting

Before you download the firmware, make sure your device is ready for the procedure. Neglect of preparation is the main reason for "bricking" smartphones. Start by checking the current version of MIUI:

• 📱 Device Model: Find out the exact model in Settings → The phone. → A model, for example, Redmi Note 11 Pro 5G Redmi Note 11 Pro (4G) require different firmware!
• 🔢 Version. MIUI: Write down the current version (for example, MIUI 14.0.5 Global – This will help you choose the right file to update.
• 🔓 bootloader status: Check if it is unlocked by the fastboot oem device-info team. If the answer is Device unlocked: false, you will need to unlock it.
• 🔋 Battery charge: At least 60% - if the power fails during firmware, the device can fail.

Also prepare:

• 💻 Windows PC 10/11 (for the Mi Flash Tool or ADB). Nana Mac/Linux Some of the tools work with limitations.

2. Official ways of firmware: update via Recovery and Fastboot

If you need to upgrade to the latest version of MIUI without losing warranty, use official methods. These are divided into two types: through Recovery (saves data) and through Fastboot (complete flashing with cleaning).

Firmware through Recovery (without loss of data)

This method is suitable for upgrading the current version of MIUI to a new one if:

• 📲 The device is switched on and operating stably.
• 🔄 You are updated within a single branch (e.g., with a MIUI 13 on MIUI 14).

3. Unlocking the bootloader: a mandatory step for new models

Since 2018, Xiaomi has been blocking the bootloader on all new devices, which means that it will require official unlocking to firmware via Fastboot or install custom software, except for an update via Recovery (see section 2.1).

The unlocking process includes:

1. Linking the Mi Account to the device (required! without this, unlocking is impossible).
2. Waiting 168 hours (7 days) after a tether is Xiaomi’s rule for theft protection.
3. Mi Unlock Tool is the official utility from Xiaomi.

Step-by-step:

1. Download and install Mi Unlock Tool from the official website.
2. Log in to your Mi Account on your smartphone and enable sync in Settings → Mi Account.
3. Go to Settings → Additional → For developers and activate OEM Unlocking.
4. Connect your smartphone to your PC in Fastboot mode and launch the Mi Unlock Tool.
5. Sign in to the same Mi Account as your smartphone, and if you see a 168-hour wait, wait until it's over.
6. After the expiration of the deadline, try again - the bootloader will be unlocked.

To install custom firmware will require:

1. Unlocked boot loader (see Section 3).

6. If you need Gapps, install them immediately after you have firmware (no reboot!).
7. Reboot → System: The first boot can take 10-15 minutes.

💡

Before installing custom firmware, check its compatibility with your model on the XDA Developers forum. Some firmware requires additional patches (for example, to operate an NFC module or camera).

5. Typical firmware errors and their solutions

Even if you follow the instructions strictly, you can get errors.

If the device stopped turning on after a failed firmware, try:

1. Download to Fastboot (Power + Volume Down) and flash the official version through the Mi Flash Tool.
2. EDL (9008) mode – this will require a special cable or testpoints (only for power users!).
3. Contact the Xiaomi service center (if the warranty is valid, do not talk about firmware attempts!).

💡

If your smartphone doesn't respond to any combination of buttons, it's not always a brick. Try holding the Power button for 30-60 seconds, sometimes the device falls asleep after a failed firmware.

Firmware through EDL (9008): the last method for "bricks"

EDL (Emergency Download Mode, 9008) is the last chance to restore a device if it does not respond to Fastboot or Recovery.

Please note:

• ⚠️ The method requires an authorized account (for new models) or special equipment (EDL cable or testpoint).
• ⚠️ Wrong actions can finally bring the device down.
• ⚠️ On some models (e.g. Xiaomi) 12/13 series) EDL blocked at the program level.

Instructions (for experienced users!):

1. Download firmware in.mbn or.elf format (for example, with Xiaomi Firmware Updater).
2. Connect your smartphone to your PC in EDL mode: Use EDL cable (closes contacts on the board). or find test points for your model (requires disassembly of the device!).

⚠️ Attention: Firmware through EDL Without authorization (for new models) it will cause an error. SLA Auth Fail.In this case, you will need an official authorized Xiaomi account or the help of a service center.

7.How to check firmware success and avoid problems in the future

After the firmware, you need to make sure that the device is working correctly.

• 📶 Network and Communication: Check the Work SIM-maps, Wi-Fi, Bluetooth and GPS. Custom firmware may not have drivers for some modules.
• 🔋 Charging and battery: Make sure the smartphone is charging and displays the correct percentage of charge.
• 🎵 Sound and speakers: Test volume, microphone and 3.5mm connector (if available).
• 📷 Camera: Take a photo on the main and front cameras - on some custom firmware, the camera may not work.
• 🔒 Security: Check fingerprint and facial recognition (if supported).

To avoid problems in the future:

• 🔄 Regularly update the firmware (especially custom) through Settings → Updating the system or TWRP.
• 📥 Download firmware only from trusted sources (official Xiaomi website, XDA, Xiaomi Firmware Updater).
• 🔧 Do not install Magisk or Xposed modules on unstable firmware – this can cause freezes.
• 📡 Before firmware, check other users' reviews about a particular build (for example, on the 4PDA).

💡

If after firmware the smartphone began to discharge quickly, perform battery calibration: completely discharge the device before turning off, then charge to 100% without interruptions. Repeat the procedure 2-3 times.
