Xiaomi’s Full Reboot: From Reset to Firmware

Xiaomi smartphones are known for their stability, but even they eventually start to slow down, give out errors or simply require a “clean start.” A complete restart of the device is not only a factory reset, but also the ability to reflash the system from scratch, remove accumulated debris or even install alternative software. However, the wrong actions can turn the phone into a “brick.” In this article, we will examine all the ways from a safe reset through the menu to deep flashing through Fastboot and EDL, taking into account the nuances for different models (Redmi, POCO, Mi).

It's important to understand that the term "reset" is interpreted differently by users, someone means soft reset, someone means hard reset, and someone wants to completely reinstall the firmware. We'll look at all the options, including emergency measures for "brick" devices, if your Xiaomi is stuck on the logo, does not turn on or just works unstable, here you will find a solution.

1.Reboot Preparation: What to Do Before Resetting

Before you reset or reflash Xiaomi, follow critical steps that neglect can lead to data loss, Mi Account lockdown, or even device failure.

First, back up. Even if the phone doesn't turn on, some data can be saved through the ADB or external drive. Use the built-in Backup app → About the phone → Backup] or third-party utilities like Titanium Backup (requires root).

• 📱 Contacts (export to.vcf)
• 📷 Photos and videos (copy to PC or cloud)
• 🔑 Passwords from Wi-Fi (Settings) → Wi-Fi → Save networks)
• 📄 Documents from Download folder and root directory

Second, check the status of your Mi Account. If your device is linked to Mi Account, you may need to enter your login/password after the reset.

• 🔓 You remember the login data (email/ Phone + Password)
• 📱 Device not locked on IMEI (check i.mi.com)
• 🔄 Two-factor authentication is disabled on your account (or you have backup codes)

⚠️ Warning: If you bought Xiaomi with your hands and the previous owner didn’t untie your Mi Account, the phone may be locked after the reset, in which case you will need to contact Xiaomi with proof of purchase.

Third, charge the battery to at least 50%, interrupting the reset or firmware process due to discharge can cause software damage.

• 🔌 Original. USB-cable (better from the set)
• 💻 Windows computer 7/10/11 (Fastboot-based)
• 🛠️ Utility: Mi Flash Tool, ADB/Fastboot, Qualcomm drivers (for EDL mode)

2.Soft reset: reboot and reset settings via menu

If Xiaomi works but it’s laggy, spontaneously reboots, or it’s giving out app errors, start with a soft reset. This is the safest way to do so without affecting user data.

Method 1: Regular reboot

• 🔄 Press the Power button for 5-10 seconds.
• 📱 In the menu that appears, select Restart.
• 🕒 Wait 1-2 minutes, the system will restart without losing data.

Method 2: Reset settings (without deleting files)

This method will return to the factory parameters only system settings, without touching photos, videos and documents:

1. Open Settings → About the phone → Reset settings.
2. Select Reset all settings (do not delete all data!).
3. Confirm the action and wait for the completion (the phone will restart).

Method 3: Cache reset (helps with application lags and errors)

• 📱 Go to Settings. → Memory. → Cleanup.
• 🧹 Click Clear Cache (Temporary garbage, but not personal data, will be removed).
• 🔄 Reset the device.

⚠️ Warning: If there are problems after a soft reset (e.g., the phone is warming or discharged quickly), the cause may be a hardware malfunction (battery wear, motherboard damage).

💡

If Xiaomi started to slow down after the MIUI update, try to roll back to the previous version via Recovery. To do this, download stable firmware from the site en.miui.com and select Install update.zip from the recovery menu.

3 Hard Reset via Recovery Mode

If Xiaomi is not turned on, stuck on the logo or locked with a pattern lock, you will need a hard reset via Recovery Mode, which removes all data from internal memory, including photos, apps and settings.

How to log in to Recovery Mode:

1. Turn off the phone (press Power + Volume up for 10 seconds).
2. Press Power + Volume up and hold until the Mi logo appears.
3. Release the buttons and the Recovery menu will appear (in English or Chinese).

Resetting instructions:

• 🌐 Select a language (if available) or go straight to Wipe Data.
• 🗑️ Press Wipe All Data (or Clear All Data in newer versions).
• 🔘 Confirm the action with a swipe or a Confirm selection.
• 🕒 Wait until the process is completed (the process will take 2-5 minutes).
• 🔄 Select Reboot to Reboot.

Once reset, the phone will start as new.

• 📱 Complete the initial setup (language selection, Wi-Fi connection).
• 🔓 Enter Mi Account data if the device has been tied.
• 📲 Restore data from a backup (if it was created).

4.Fastboot flashing: clean MIUI installation

If the reset didn’t help or you want to install clean firmware (for example, switch from Chinese MIUI to global), use Fastboot mode.This method is suitable for most Xiaomi models, except for devices on the Mediatek processor (they need the SP Flash Tool).

What you need:

• 💻 Windows computer and administrator rights.
• 🔌 Cable USB Type-C (original).
• 📦 Firmware in.tgz or.zip format (download from the official website).
• 🛠️ Utility: Mi Flash Tool, ADB/Fastboot (download from Android site).

Step-by-step:

1. Install drivers: Download and install Mi Phone Manager or Qualcomm drivers manually.
2. Unpack the firmware: Unpack the firmware file (e.g., cmi_global_images_V12.5.1.0.RJKMIXM_20210312.0000.00_11.0_global.zip) into a folder without Cyrillic (e.g., C:\MIUI\rom).
3. Launch Mi Flash Tool: Open the utility on behalf of the administrator, click Select and specify the path to the unpacked firmware.
4. Turn your phone into Fastboot mode: Turn off the device. Press Power + Volume down until the rabbit in the hat appears.
5. Connect your phone to your PC: The Mi Flash Tool will have a device (e.g., COM3). Select the firmware method: Clean All – Clean All (recommended). Clean All and Lock – Clean + Lock the bootloader (for security).

Start the firmware:

Press Flash and wait for completion (10-15 minutes).

⚠️ Warning: Fastboot firmware with Clean All and Lock will block the bootloader. If you plan to install custom firmware (like LineageOS), choose Clean All only.

5. Recovery through EDL: When nothing helps

EDL (Emergency Download Mode) is a last-ditch Xiaomi experience that doesn’t turn on, isn’t defined by Fastboot, or has a damaged bootloader. In this mode, the firmware is downloaded directly into the device’s memory, bypassing the bootloader. Danger: wrong actions can finally “kill” the phone.

When you need an EDL:

• 🔴 The phone does not respond to buttons and does not charge.
• 🐢 Hangs on the Mi logo after a failed firmware.
• 🔌 Not defined in Fastboot (the fastboot device command does not show the device).
• 📱 Boot or recovery section damaged.

How to log into EDL:

There are two ways:

1. Hardware (for Snapdragon): 1. Turn off the phone. 2. Press Volume up + Volume down and connect the USB cable to the PC. 3. Hold the buttons for 10-15 seconds until the Qualcomm HS-USB QDLoader 9008 appears in Device Manager.
2. Software (via ADB): Adb reboot edl only works if ADB is enabled in the developer settings.

Firmware via EDL:

The Mi Flash Tool (the same as the Fastboot) will be required to work, but with additional Qualcomm drivers:

1. Download the firmware for EDL (file with.mbn or.elf extension).
2. In the Mi Flash Tool, select firmware and connect your phone in EDL mode.
3. Press Refresh – the device should be defined as COMX.
4. Select the Clean All method and start the firmware.

⚠️ Warning: Firmware through EDL may result in loss of IMEI or serial number if the firmware files are corrupted. Always use official firmware from Xiaomi's website.

💡

EDL mode is an emergency method that should only be used if other methods (Recovery, Fastboot) have failed.

6.Reboot after flashing: setup and optimization

After a complete reset or flashing, Xiaomi requires an initial setup.To avoid future problems, follow these guidelines:

Step 1: Initial settings

• 🌍 Select a region of Russia (or your country) and this will affect the available services of Google and Mi.
• 📶 Connect to Wi-Fi (do not use mobile data to download updates).
• 🔓 Enter your Mi Account details (if the phone was tied).
• 🔄 Turn off automatic diagnostics (Settings → About Phone → Send an Error Report).

Step 2: Optimizing Productivity

• 🚀 Enable Performance Mode (Settings → Special Opportunities → Performance Mode).
• 🗑️ Clear the cache after first running (Settings → Memory → Cleaning).
• 🔋 Calibrate the battery: fully discharge and charge the phone 2-3 times in a row.
• 🛡️ Install an antivirus (such as Malwarebytes) and check the system.

Step 3: Data recovery

• 📱 Restore contacts from a.vcf file or Google Account.
• 📷 Move photos and videos from your PC or cloud (Google Photos, Mi Cloud).
• 🎮 Install apps only from Google Play (avoid APK from unknown sources).

Step 4: Update the software

• 🔄 Check for updates (Settings → About Phone → System Update).
• 📦 If a new version MIUI is available, install it (but not through the Beta channel unless you are sure of stability).
• 🔒 After the update, restart the phone.

💡

If you have lost sound or the sensor is not working, check the firmware version. You may have installed software for another model. Compare the name of the firmware file with the code name of your device (for example, cmi for Mi 10 Pro).

7. Frequent errors and their solutions

Even if you follow the instructions, you can have problems, and let's look at the typical mistakes and how to fix them:

Additional advice:

• 🔧 If the Mi Flash Tool is showing an error 0x80070002, try running it in Windows 7 compatibility mode.
• 📡 If there is no network after the firmware, check the settings of APN (Settings → SIM-maps and mobile networks → Access Points (APN)).
• 🔋 If the phone discharges quickly after reset, calibrate the battery (discharge to 0% and charge to 100% without interruption).
