How to reflash Xiaomi device correctly: a step-by-step guide with error analysis

Reflashing Xiaomi devices is a process that can bring a locked smartphone back to life or turn it into a brick if you approach it without preparation. Unlike standard air updates, hand firmware requires an understanding of nuances: From choosing the right version MIUI to working with tools like the Mi Flash Tool or Fastboot. This article will help you understand when flashing is really necessary and when resetting is enough, what tools will be needed for different models (from Redmi Note 12 to Xiaomi 14 Ultra), and how to avoid typical errors, such as bootloop or loss IMEI.

It's important to understand that the procedure for smartphones, Mi TVs and Mi Band smartwatches is radically different, and here we'll focus on mobile devices, the most popular candidates for flashing. If your goal is to remove the browser, get root rights, or install Global ROM instead of the Chinese version, you'll find relevant methods for 2026, including bypassing Xiaomi's new restrictions on unlocking the bootloader.

Be warned: since March 2023, Xiaomi has tightened its bootloader unlock policy – some models now require up to 360 hours (15 days) of waiting after linking a Mi Account to a device – a nuance that often causes failures, so we’ll take a closer look at how to minimize latency and what alternative methods exist to circumvent this restriction.

1. When you need flashing: 5 good reasons and 3 times when it is useless

Many users resort to flashing the first time they fail, although it is often easier to solve the problem. Let's understand in which situations the procedure is justified and when it is only a waste of time (or even dangerous).

Good reasons for reflashing:

• 🔄 System failures after OTA- upgrade: the device is constantly restarting, apps are crashing, and resetting doesn't help. For example, after upgrading to MIUI 15 on Poco F5, some users experience a com.android.phone error.
• 🌍 Regional firmware change: you bought a smartphone with Chinese ROM (CN ROM) and want to switch to global (Global ROM) or European (EEA ROM) for full-fledged Google services.
• 🔓 Unlock custom firmware bootloader: Plan to install LineageOS, Pixel Experience or get root access through Magisk.
• 📱 Brick recovery: The device does not turn on, hovers on the Mi logo, or shows an error This device is locked.
• 🚀 Performance optimization: Official firmware is slowed down by pre-installed apps (bloatware), and alternative builds (e.g. Xiaomi.eu) offer a “clean” system.

When you don't need a flashing:

• ⚠️ The device is just slow-moving — try clearing the cache first in Settings → Memory → Cleanup.
• ⚠️ Battery problems (fast discharge) – often background processes are to blame, not firmware.
• ⚠️ Application-specific errors (such as Mi Fit or Mi Home) – reinstall them or update them via Google Play.

⚠️ Warning: If your Xiaomi is warranty-bound, the flashing will cancel it. The manufacturer can easily detect the interference by the bootloader status (Locked/Unlocked) and the tags in the misc section.

2. Preparation for flashing: checklist and necessary tools

Unprepared flashing is a direct route to the "bricking" of the device. Before you start, collect everything you need and follow the preliminary steps.

What you need:

• 📱 Device charge of at least 60% – interruption of the process due to battery discharge can render the smartphone inoperable.
• 💻 Windows PC 10/11 (for Mi Flash Tool) or Linux/macOS (for fastboot via terminal).
• 🔌 Original. USB-cable – cheap cables can’t transmit data in Fastboot mode.
• 🔐 Mi Account with a linked phone number (to unlock the bootloader).
• 📁 Firmware is official (from Xiaomi) or custom (for example, from xiaomi.eu).

Download the Mi Flash Tool (last version)|Check the device model in Settings → The phone.|Backup your data via Mi Cloud or TWRP|Disable the antivirus (it can block the drivers)|Make sure there is enough space on the PC (firmware weighs) 2-4 GB)-->

How to find out the exact model of the device:

1. Go to Settings → About Phone → MIUI version.
2. Several times tap on the item Version of the kernel - a menu with detailed information will open.
3. Remember or write the Model Number (e.g. 23049PCD8G for the Redmi Note 12 Pro+).

Select firmware: For stable work, take official builds marked Stable. If you need the latest features, Developer will do (but it may contain bugs). For custom firmware, check compatibility with your model on the XDA Developers or 4PDA forums.

⚠️ Warning: Firmware for Xiaomi and Redmi are not interchangeable, even if the devices are similar in appearance. For example, the firmware from Redmi Note 11 Pro 5G (veux) will not work for Redmi Note 11 Pro 4G (peux) – this will lead to hard brick (irreparable damage).

3. Unlocking the bootloader: bypassing Xiaomi's restrictions in 2026

Since 2023, Xiaomi has tightened the process of unlocking the bootloader by introducing a mandatory wait of up to 360 hours (15 days) after linking a Mi Account to the device, a move aimed at combating device theft but creating inconveniences for legitimate users.

The official way (via Mi Unlock Tool):

1. Download the Mi Unlock Tool (the latest version).
2. Turn on the smartphone Developer Mode (7 taps on the MIUI version in the settings) and activate OEM Unlock in the menu for developers.
3. Link your Mi Account to your device in Settings → Xiaomi Account.
4. Connect your phone to your PC in Fastboot mode (clip Volume Down + Power when the device is off).
5. Launch the Mi Unlock Tool, log in to your account and follow the instructions.

How to speed up the process:

• 🔄 Count reset: If you previously linked an account but didn't unlock the bootloader, try untie the device, reset the settings, and re-link the account, sometimes it resets the timer.
• 📡 Utilization of VPN: Some users report that connecting to Xiaomi servers via VPN (e.g., Hong Kong or Singapore) reduces latency to 72 hours.
• 🛠️ EDL- Mode: For some models (e.g., the Redmi Note 10 Pro), there is an unofficial method of unlocking via Emergency Download Mode, but it requires an authorized Xiaomi account and a special cable.

Unofficial methods (at your own risk):

• 🔓 Test firmware bypass: Some MIUI builds (e.g., for Poco F3) allow you to unlock the bootloader without waiting, but this doesn’t work on all devices.
• 💰 Paid services: AliExpress or Telegram channels offer $5-20 unlock, but there is a risk of fraud.

4. Flashing techniques: from Fastboot to TWRP

There are three main ways to flash Xiaomi devices, each of which is suitable for different scenarios, and the choice of method depends on the current state of the device (whether it works, whether the bootloader is unlocked) and the goals (official or custom firmware).

Comparison of methods:

Step-by-step instructions for the Mi Flash Tool (the most versatile method):

1. Download and install the firmware in.tgz format for your model.
2. Unpack the archive in a folder without Cyrillic characters (for example, C:\Xiaomi\proshivka).
3. Install the Mi USB Driver (comes with 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. In the program, click Select, specify the path to the firmware folder, then select Clean all (full cleaning) or Clean all and lock (with bootloader lock after firmware).
7. Press Flash and wait until it is completed (usually 5-10 minutes).

Important nuances:

• 🔹 If the firmware doesn’t see the device, try a different USB- port or disable the driver signature in Windows.
• 🔹 For models with MediaTek (e.g., Redmi 10C), use the SP Flash Tool instead of the Mi Flash Tool.
• 🔹 If the device is stuck on the logo after the firmware, try repeating the process with the Save user data mode.

💡

If the Mi Flash Tool is 0x80070002 error, check that the path to the firmware does not contain spaces or Cyrillic characters. Move the firmware folder to the root of the disk (for example, C:\rom\).

5. Install custom firmware: Xiaomi.eu, LineageOS and others

Custom firmware offers new opportunities: no advertising in MIUI, advanced settings, support for Google Camera, and even installing Google services on devices for the Chinese market, but their installation requires an unlocked bootloader and often a custom TWRP recavator.

Popular custom firmware for Xiaomi:

• 🌐 Xiaomi.eu is a modified MIUI without a browser, with support for all languages and weekly updates.

How to install custom firmware through TWRP:

1. Download TWRP for your model from the official website or XDA.

Common mistakes and their solutions:

• 🔴 Error 7 in TWRP: means the firmware is incompatible with your model. Check the device name in Settings → About Phone.
• 🔴 Bootloop after installation: Try flashing the kernel (boot.img) separately or installing a different firmware version.
• 🔴 No network after firmware: maybe a IMEI crashed. Restore it via QCN- recovery or Maui META tool.

💡

Before installing custom firmware, be sure to check its compatibility with your model on the XDA Developers forum. firmware for the Redmi Note 11 (spes) will not work for the Redmi Note 11S (fleur), even if the devices are externally identical.

6.Recovery after a failed firmware: saving the "brick"

If the device stopped turning on, stuck on the logo or shows an error This device is corrupted, do not panic - in 90% of cases it can be restored.

• 🧱 Soft brick: The device is powered on but not booted (hangs on logo, bootloop).
• 🧱 Hard brick: The device does not respond to buttons, is not detected by the PC (often after a failed firmware through the SP Flash Tool).

Recovery methods:

1. Soft brick (bootloop, boot errors):

• 🔄 Fastboot your device with Clean All mode.
• 🔧 If the bootloader is unlocked, install the firmware via TWRP.
• 📱 For devices with MediaTek, use the SP Flash Tool with the scatter.txt file.

2. Hard brick (the device does not respond):

• 🔌 Connect the device to your PC and check if it is defined in Device Manager as Qualcomm HS-USB QDLoader 9008 (for Snapdragon) or MediaTek Preloader.
• 🛠️ For Qualcomm: Use EDL- mode and run through the Mi Flash Tool with an authorized account.
• 🛠️ For MediaTek: Flick through the SP Flash Tool with Format All + Download tick.

3. Loss of IMEI:

• 📡 Restore IMEI via the engineering menu (#4636###) or the Maui tool META (for MediaTek).
• 📡 For Snapdragon, use QCN- Recovery (modemst1/modemst2 section backup is required).

⚠️ Warning: If the device is not detected in EDL- mode, the USB- port or power controller may be damaged. In this case, repairs will be required at the service center. Don't try to disassemble the device yourself - many Xiaomi models (such as Xiaomi 13) have adhesive housing, and a sloppy opening can damage the plumes.

7.Optimization after firmware: what to do next

Successful firmware is only half the battle, so to keep the device running smoothly, follow a few additional steps:

Initial setting:

• 🔧 Go through the initial setup, but don’t restore data from the backup right away — check the stability of the system first.
• 🔄 Update all apps via Google Play or Mi App Store.
• 📱 Enable Developer Mode and activate Debugging using USB (in handy for future manipulations).

2. Remove Bloatware (pre-installed applications):

• 🗑️ Use ADB to remove unnecessary applications: adb shell pm uninstall --user 0 com.miui.analytics adb shell pm uninstall --user 0 com.xiaomi.midrop
• 📦 Universal Android Debloater is suitable for mass removal.

3. Performance optimization:

• ⚡ Enable MIUI Optimization in the developer settings (improving interface smoothness).
• 🔋 Disable AutoRun for unnecessary applications in Settings → Applications → Permissions.
• 🎯 For games, activate Performance Mode in Settings → Special Features.

4. Safety after unlocking the loader:

• 🔒 Install Magisk to manage root rights and hide unlock status from banking applications.
• 🛡️ Set up a Firewall (like NetGuard) to block unnecessary network connections.
• 🔄 Check firmware updates regularly through Settings → System Update.

💡

If Google services stop working after firmware (for example, Google Play gives an error), install NikGapps or OpenGapps via TWRP. Select the version corresponding to your firmware (Android 12/13/14).
