How to unlock a contact on a Xiaomi phone: from simple methods to technical solutions

A blocked contact on a Xiaomi smartphone is a problem that users face after resetting their settings, changing their Mi Account or activating the Blacklist feature. Unlike unlocking their phone, which requires resetting FRP or bypassing a Google account, restoring access to contacts often comes down to working with system settings or backups. However, not everyone knows that Redmi, POCO and Mi devices have at least 5 ways to return access to locked numbers, from standard tools to technical bypasses.

In this article, we’ll look at all the current methods of unlocking contacts, including recovering from Mi Cloud, bypassing restrictions without losing data, and even manually editing system files for power users. We’ll focus on the nuances that Xiaomi doesn’t advertise: for example, why contacts can remain blocked after resetting to factory settings, and how to fix it without losing any other data. If you tried to unlock a number through a standard menu, but nothing worked, here you will find alternative solutions.

Why Contacts Are Blocked on Xiaomi: The Main Reasons

Before we get to the instructions, it’s important to understand why the phone blocked contact, and on Xiaomi devices, there are three key reasons why this happens:

• 🔒 Manually locking through a "Blacklist"; a user or an application (such as anti-spam) has added a number to the blocked list, in which case it takes 2 minutes to unlock.
• 🔄 Resetting settings without detachment Mi Account. After a hard reset, the phone can block contacts tied to a previous Xiaomi account.
• 📱 Synchronization conflict: If the contacts are synced to Google and Mi Cloud at the same time, the system can block duplicate records.

Less commonly, the problem arises from damage to the contact database (the contacts2.db file in /data/data/com.android.providers.contacts/databases/.This is typical for devices after a failed MIUI update or manual intervention in system files. In such cases, standard unlock methods will not work - you will need to restore backup or manual editing.

⚠️ Note: If contact is blocked after purchasing a used phone, there is a high probability that the previous owner did not untie his Mi Account. In this case, unlocking through standard methods is impossible - you will need a reset. FRP (Factory Reset Protection).

Method 1: Unlocking through the standard "Blacklist" menu

The easiest method is to check if a contact has been added to the blocked number list, which is true if you have blocked the number yourself or if an application (for example, Security or Truecaller) has done so.

Instructions:

1. Open the phone application (pipe icon).
2. Click on the three dots in the upper right corner → Settings → Lock numbers.
3. In the list, find the blocked contact and swipe it left or click Delete.
4. Reboot your phone to make the changes take effect.

If the number lock menu is empty but contact is still unavailable, check the Security app settings:

• 🛡️ Go to Security. → Lockdown → Blacklist.
• 🔍 Use a number search – sometimes contacts are blocked not through the standard menu, but through built-in anti-spam.

If the contact is not displayed in any of the lists, but the calls and SMS do not pass, the problem may be due to the synchronization of accounts.

Method 2: Recover contacts through Mi Cloud

If contacts were blocked after resetting or changing Mi Account, they can be restored through Xiaomi cloud storage.This method only works if sync with Mi Cloud was previously enabled.

Step-by-step:

1. Open your Settings → Xiaomi Account → Mi Cloud.
2. Sign in with the same account you used before you were blocked.
3. Go to Contacts and enable synchronization.
4. Wait until the process is completed (it can take up to 10 minutes).
5. Check if the blocked contacts appear in the phone book.

If contacts are not restored:

• 🔄 Try to log out of your account and log in again.
• 📱 Make sure there is enough memory on the phone – if there is a lack of space, synchronization may be interrupted.
• 🌐 Check your internet connection – Mi Cloud requires a stable connection.

⚠️ Note: If the phone was bought with your hands and the previous owner did not untie his Mi Account, you will not be able to log into the cloud. FRP (see method 5).

Method 3: Unblocking through Google Contacts

If contacts are synced with a Google Account, they can be restored even after resetting, a method that is universal for all Android devices, including Xiaomi.

What to do:

1. Open Settings → Accounts → Google.
2. Select your account and enable Contact Sync.
3. Wait 5-10 minutes and check the phone book.
4. If contacts do not appear, go to contacts.google.com from your computer, find the blocked number and export it to the.vcf file, then import it to your phone.

A critical caveat: if a contact was blocked at the system level (not through a blacklist), it may not be in Google Contacts.

Method 4: Manual editing of the contact database (for experienced)

If standard methods have failed and contacts are physically stored in the phone’s memory but are not available, you can try editing the database manually, which requires root rights and is only suitable for users with ADB or Android file system experience.

Instructions:

1. Install Root Explorer or FX File Explorer (with root rights) on your phone.
2. Go to /data/data/com.android.providers.contacts/databases/contacts2.db
3. Copy the contacts2.db file to your computer and open it via SQLite Browser.
4. Find the table. raw_contacts Check if there is a blocked contact.
5. If there is a record but it is marked as blocked, change the deleted field from 1 to 0.
6. Save the file and return it to your phone by replacing the original.
7. Reset the device.

⚠️ Attention: Incorrect editing of the file contacts2.db This can cause you to lose all contacts. Make a backup copy of the file before you start!

Method 5: Reset FRP and Fully Unlock the Phone

If contacts are blocked due to being linked to someone else’s Mi Account or Google Account (for example, after buying a used phone), a full FRP reset (Factory Reset Protection) is required, as it will delete all data from the device.

How to Reset FRP on Xiaomi:

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery Mode.
3. Select Wipe Data → Wipe All Data (use volume buttons for navigation, power button for confirmation).
4. After the reset, the phone will restart. At the setup stage, skip the account binding (if possible).
5. Restore contacts from backup (if any).

If the phone still requires you to enter your previous account data after reset, you will need to bypass FRP using special tools (for example, Mi Account Unlock Tool or SP Flash Tool), a process that is technically complex and can damage the device if executed incorrectly.

💡

Before resetting FRP, check if the phone is linked to your Xiaomi account via account.xiaomi.com. If the device is listed as tied, try removing it remotely.

Frequent Mistakes and How to Avoid Them

When you unlock your contacts on Xiaomi, users often make mistakes that make it difficult to do, and here are the most common ones:

• 🔧 Reset settings without backup. Before any manipulation of contacts, export them to.vcf via Contacts → Settings → Exports.
• 🔒 Ignoring two-factor authentication if Mi Account is secure 2FA, To log in to Mi Cloud, you will need a code from SMS or an authorizing application.
• 📲 Use of informal firmware. MIUI (For example, Xiaomi.eu may not work standard methods of unlocking.
• 🔄 Incomplete sync. Once you've reconnected through the cloud, wait until the process is complete, and the interruption will result in duplication or loss of records.

Another common problem is that contacts are displayed, but calls are not made.

• Operator-level locking (check through the USSD-request *#62#).
• Limitations in settings SIM-maps (go to Settings) → SIM-maps and mobile networks → Call settings).
• Application conflict (turn off antispam in Security or Truecaller).

💡

If the contact is blocked at the operator level (for example, due to debts), unlocking via the phone will not help.
