Xiaomi phone lost: how to block and protect data

Losing a smartphone is stressful, especially if the device stores personal photos, access to banking applications or work correspondence. Xiaomi smartphones are equipped with built-in tools for remote locking, but many users do not know how to use them in a critical situation. It is important to act quickly: according to statistics, 34% of stolen phones are blocked by owners in the first 30 minutes after loss, which significantly reduces the risk of unauthorized access to data.

In this article, we will discuss the current ways to block a lost or stolen Xiaomi in 2026, including the official Mi Account and Find Device services, alternative methods through the carrier, as well as instructions for protecting accounts from hacking. We will analyze what to do if the phone is turned off, how to track its location and why a standard factory reset does not always save you from fraud. All methods are tested on Redmi Note 12, POCO X5, Xiaomi 13T and other current devices of the brand.

1.Blocking through Mi Account – the official way from Xiaomi

The most reliable and quickest method is to use Find Device (formerly Mi Cloud), which is linked to a Mi Account, which allows you not only to lock the device, but also to track its location, turn on the beep or erase data remotely, the main condition is that the phone must activate Find the device in the security settings.

To lock the phone:

• 🌐 Go to account.xiaomi.com and log in to your Mi Account (the same as your lost phone).
• 🔍 From the menu, select Find Device. If you have multiple gadgets, select the one lost from the list.
• 🔒 Click Lock Device and set a new password (minimum 6 characters).This password will be requested when you turn on your phone.
• 📍 Optionally: activate the option to show the last location to see the coordinates of the phone on the map (works if the device is connected to the Internet).

Make sure your phone is connected to the Internet (Wi-Fi/mobile network)

Check that the “Find Device” function has been enabled in the settings

Access to an email or phone number linked to your Mi Account

Prepare a backup recovery code (if any)

-->

An important nuance: if the attacker has already reset the phone to factory settings, locking through Mi Account may not work, in which case only communication with the operator to block IMEI (about this in the next section) will help. Also note that after locking through Find Device, you can only unlock the phone by entering your password, even if the attacker resets it through Recovery Mode.

💡

If you don’t remember whether Find Device was enabled on your phone, check it through another Xiaomi gadget authorized under the same account. Go to Settings → Mi Account → Find the device and see the list of connected devices.

2. IMEI blocking through the operator

If your phone is turned off, discharged, or has an internet connection disabled, Mi Account locking will not work, and the only reliable way to do so is to lock your phone via IMEI via your mobile carrier. IMEI (International Mobile Equipment Identity) is a unique 15-digit device identifier that allows you to lock your phone at the network level, making it useless for attackers.

How to lock your phone by IMEI:

1. Find it. IMEI You can see the lost phone: 📄 On the phone box (usually a barcode sticker). 📱 In the settings of another Xiaomi phone, if it was synced with the same Mi Account (Settings section) → The phone. → General information). 💾 Google backup (if synchronization was enabled).
2. Contact the operator: 📞 MTS: Call the number. 0890 Or contact the communication salon with a passport. 📞 Beeline: 0611 or through a personal account on the website. 📞 MegaFon: 0500 or 8-800-550-05-00. 📞 Television2: 611 or via in-app chat.

Tell the IMEI operator and ask to lock the device. The lock will take effect within 24 hours.

Critical information: IMEI lock is irreversible. If you find a phone after locking it, it will not be possible to unlock it through the operator - you will need to formally contact Xiaomi with proof of ownership, so use this method only as a last resort when other methods are not available.

3. Remote erasure of data: when necessary

If your phone has critical data (bank access, corporate information, personal correspondence) and the chances of returning the device are minimal, it makes sense to delete all data remotely, a feature that is available through Find Device, but only works if the phone is connected to the Internet.

How to erase data:

1. Go to Mi Account and select the lost device.
2. Click on Erase Data (Erase Data).
3. Confirm the action by entering the password from the account.
4. Wait until the process is completed (it can take up to 10 minutes).

Once erased, the phone will return to factory settings, but Mi Account lock will remain active, meaning that an attacker will not be able to use the device without your login data.

• ⚠️ Data will be permanently deleted, including photos, contacts and messages, if not synced to the cloud.
• ⚠️ If the phone is turned off, the erasure command will be executed the next time you connect to the Internet.
• ⚠️ In some models (for example, POCO F5) After erasing, you may need to enter your Mi Account password even to reset.

Yeah, but I found it myself.

Yeah, the phone was stolen.

No, I never lost.

I don't know where he is now.-->

4 What to do if the phone has already been dropped by an attacker

If the attacker has managed to reset the phone to the factory settings (Hard Reset), the standard methods of blocking through the Mi Account may not work, in which case, proceed with the following algorithm:

1. Check your account binding: new Xiaomi models (released after 2021) even after a reset require you to enter the Mi Account data that was tied to the device (FRP).
2. Contact Xiaomi Support: If the phone is locked at FRP level but you don't remember the password, contact support with proof of purchase (check, warranty card).
3. Block it. SIM-Card: Call the operator and ask to block SIM-Card so that the attacker cannot use your number to cheat.
4. Change passwords: Change passwords from all important services (banks, social networks, mail) immediately, especially if they were saved in the phone’s browser.

On older models (e.g. Redmi 4X or Mi A1), the FRP may not work and after the reset, the phone will be fully available to the new user, in which case only IMEI locks through the operator remain.

💡

Even if the phone is dropped, locking the IMEI will make it useless for attackers – they will not be able to call, use the mobile Internet or sell the device legally.

5. How to protect data before losing your phone: prevention

The best way to avoid problems is to set your phone up in advance so that data is safe in the event of theft or loss.

• 🔐 Turn on the screen lock: use PIN-A code (minimum 6 digits) or a pattern lock. Fingerprint and facial recognition are convenient, but they can be fooled.
• 🌥️ Activate Find Device: Go to Settings → Mi Account → Find the device and turn on the option. Also check that geolocation is enabled.
• ☁️ Set up backup: in Settings → Google → Backup enable saving contacts, photos and app data.
• 📱 Attach trusted number: in the Mi Account settings, specify a backup phone to restore access.
• 🔄 Turn off the debugging. USB: This function (in Settings) → For developers, it allows you to bypass the lock through a connection to the PC.

We also recommend installing Google Find My Device app – it duplicates Xiaomi’s Find Device features and can come in handy if the main service doesn’t work for some reason. Remember to periodically check that all security features are enabled: after updating the firmware, some settings may be reset.

💡

Create a text file in your phone notes called "If your phone is lost" and include your backup number or email to contact you, so that an honest person who finds the phone can contact you even if the screen is locked.

6. Alternative ways to search for a phone

If standard methods do not help, you can try alternative services and techniques:

You can also report theft to the police (if the phone is stolen), and give them an IMEI device, which will increase the chances of finding it, especially if the phone is connected to the network, and in some regions, police work with operators to track the phone's last location from base stations.

7. Frequent Mistakes: What NOT to Do When You Lose Your Phone

In panic, many users take actions that only make things worse, and these are common mistakes and why they should be avoided:

• 📵 Calling a lost phone endlessly: If the phone is stolen, an attacker can turn it off or take it out SIM-I'd better send it. SMS requesting the phone back and indicating contacts for communication.
• 🔄 Self-Try to Track Your Phone Through “Secret” Apps: Many “Miracle Programs” to Track Your Phones IMEI They're either not working or they're stealing your data.
• 💰 Pay for a "guaranteed search" for a phone: no company, except the police and operators, can accurately track the phone.
• 📲 Ignore two-factor authentication: if the phone was enabled SMS-- Bank or social media login codes that an attacker can intercept. SMS-login and go to apps like Google Authenticator.

Another common mistake is to post the IMEI of a phone on social media to ask for help finding it, and fraudsters can use that IMEI to clone the device or otherwise, and only share the IMEI with the operator or the police.

💡

If you find the phone yourself, take your time to be happy, check if it has suspicious apps or is connected to unknown accounts, and sometimes attackers return phones with pre-installed spyware.
