Losing a smartphone is stressful, especially if it has a lock on the screen and no backup passwords. Xiaomi devices are protected by Mi Account, which makes it difficult to access unauthorized access, but also creates problems for legitimate owners who have forgotten account details. In this article, we will examine all the working ways to unlock a lost Xiaomi, from official methods to alternative solutions that will help restore access to personal data or at least prepare the phone for sale.
It’s important to understand that if a device is tied to a Mi Account that you don’t remember, the chances of unlocking without the previous owner are minimal, but even then there are options, from appealing for Xiaomi to using service centers with official tools. We won’t look at dubious methods like “bypassing test points” (they often lead to a device blink), but focus on legal and secure ways.
1 Unlocking through Mi Account (official method)
If you remember the username and password from Mi Account tied to a lost device, unlocking will take no more than 5 minutes, which works even if the phone is turned off or in another city – as long as it is connected to the Internet (via mobile network or Wi-Fi).
Instructions:
- 🌐 Go to account.xiaomi.com and log in to your account.
- 📱 In the Devices section, find the lost smartphone (if it is online, there will be a green tag nearby).
- 🔓 Press Find the device. → Unlock. The system will send a command to reset the pattern lock or PIN-code.
- 📲 If the phone is connected to the Internet, the lock will be removed within 1-2 minutes.
⚠️ Note: If the device is off or offline, the unlock command will only be executed after it is turned on and the Internet is available.
💡
If you have two-factor authentication (2FA) enabled in Mi Account, you will need code from an SMS or authenticator app to unlock. Make sure you have access to backup codes or a second authorization device.
2. reset to factory settings (Hard Reset)
If Mi Account is lost and the lock screen displays a message saying, "This device is lost," the radical method is to completely reset your settings. Please note, this method deletes all data from your phone, including photos, contacts and apps.
- 📦 You have a backup of your data (e.g., in Mi Cloud or Google Drive).
- 🔄 You are willing to lose all information to access your device.
- 📱 The phone is not tied to other people's accounts (otherwise, after the reset, you will need to enter data from the previous account).
How to make Hard Reset on Xiaomi:
- Turn off the device (press the power button for 10 seconds).
- Press the Power Button + Volume up until the Mi logo appears.
- In the Recovery menu, select Wipe Data (use volume buttons for navigation, power button for confirmation).
- Confirm the reset by selecting Wipe All Data.
- After the reboot, the phone will be like new – you will need to re-set.

3. Unlock through Find Device (if the phone is online)
Xiaomi's Find Device service not only tracks the location of a lost phone, but also remotely manages it. If the device is connected to the Internet, you can:
- 📍 Find out its current location (with an accuracy of 50–100 meters).
- 🔊 Turn on a loud signal (useful if the phone is lost at home or in the office).
- 🔒 Lock the device with a new password.
- 🧹 Erase all data (similar to Hard Reset, but without physical access to your phone).
How to use Find Device:
- Go to findmi.com and log in.
- Select the lost device from the list.
- Click Delete Data (this is the last chance – it will be impossible to recover information after this operation).
- Confirm the action via SMS or email.
⚠️ Note: Delete data only works if the Find Device option is enabled on the phone (Settings) → Mi Account → If it's been disabled, the service is useless.
4. Contact the Xiaomi Service Center
If all previous methods have failed (e.g., the phone is linked to someone else’s Mi Account), the official path remains to contact an authorized service center, which is the only legal way to unlock a device without the previous owner’s data, but you will need proof of ownership.
What documents are needed:
| Type of document | Requirements | Notes |
|---|---|---|
| Check or receipt | Original with purchase date and serial number | An email check from the mail will also work. |
| Guarantee pass | With a store seal and serial number. | If the warranty expires, it is not critical. |
| Phone box. | With a sticker that says IMEI. | IMEI must match the data in the phone |
| Passport of the owner | To confirm identity | Sometimes they need a copy. |
The process of unlocking in the service:
- Find the nearest Xiaomi service center (check reviews – some centers refuse to work with locks).
- Make an appointment (sometimes a preliminary request is required by phone).
- Provide your phone and documents. The specialist will send a request to Xiaomi to unlink the account.
- Expect a response (3 days to 2 weeks) If the request is approved, the phone will be unlocked.
⚠️ Warning: Some service centers offer "unofficial" unlocking via firmware or engineering menus, which is risky: the phone can turn into a "brick" or lose functionality (for example, the module will stop working). NFC Request only official unblocking via Xiaomi request!
5. Alternative methods (for advanced users)
If you are not afraid to take risks and have experience with ADB, Fastboot or firmware, you can try to bypass the lock through technical loopholes. These methods do not guarantee success and can lead to loss of warranty or breakage of the device. Use them at your own risk!
Ways for experienced users:
- 🖥️ Fastboot Firmware: Install clean firmware through the Mi Flash Tool (requires unlocked bootloader).
- 🔧 ADB-Teams: If the debugging is enabled USB, You can try to delete the lock files via adb shell rm. /data/system/gesture.key.
- 📱 EDL-Mode: Low-level firmware via Qualcomm tools (only works on phones with Snapdragon processors).
Example of a command to reset a pattern lock via ADB (if debugging is enabled):
adb shell
su
rm /data/system/gesture.key
rm /data/system/password.key
reboot⚠️ Note: Methods with firmware or ADB do not work if the phone is on anti-Rollback protection (on models after 2019!
Make sure the bootloader is unlocked | Download the official firmware for your model |Install Qualcomm Drivers |Create a backup of data (if possible) |Having a USB cable with data support on hand-->
