Unlocking Xiaomi Redmi 7A: from screen to bootloader – the full guide

Why Redmi 7A is blocked and what to do about it

Xiaomi Redmi 7A can get locked for several reasons: too many failed password attempts, a forgotten pattern lock, binding to a Mi Account after resetting settings, or an activated bootloader. Each case requires a different approach - there is no universal solution. For example, if you just forgot the screen password, a Recovery reset is enough, but when you lock a Mi Account, you will need official proof of ownership.

It’s important to understand that the Redmi 7A is a budget model with a Qualcomm Snapdragon 439 processor and a closed bootloader by default, which means that unlocking through Fastboot is only possible after getting permission from Xiaomi (the procedure takes up to 72 hours), while resetting through Recovery is available immediately, but leads to data loss. Next, we will analyze all scenarios in order from the simplest to the most complex.

Method 1: Unlock the screen through Find My Device (without loss of data)

If Redmi 7A has Google account sync enabled, you can try unlocking the screen remotely, which only works when you’re connected to the Internet (via mobile or Wi-Fi) and you’re using an active Find My Device service.

Instructions:

• 🌐 Go to Find My Device from a computer or other phone.
• 🔑 Sign in to the same Google account that is linked to Redmi 7A.
• 📱 In the list of devices, select your Redmi. 7A (If it is not, the method will not work).
• 🔒 Click “Block Device” and enter a new temporary password.
• 🔄 After 5-10 minutes, unlock the phone with the entered password and install a new pattern lock.

⚠️ Warning: If your phone is off or not connected to Wi-Fi, the lock command will not reach. Check if the notification indicator (blue or green LED) is on, which is a sign of an active connection.

This method will not work if:

• 🚫 Find My Device is disabled in Google Settings.
• 🚫 Device discharged or switched off.
• 🚫 After resetting, a new Mi Account was created that is not tied to Google.

If Find My Device can't see the phone, try connecting the Redmi 7A to charge and wait for the internet to turn on. Sometimes it helps to reboot the router to which the smartphone is connected.

Method 2: Recovery Mode (with loss of data)

The most radical, but versatile way is a hard factory reset, which will delete all data, including passwords, accounts and installed apps, but return access to the phone. On the Redmi 7A, it uses Xiaomi's standard Recovery.

5. Confirm the action by choosing “Confirm”.
6. After reset, select “Reboot” → “Reboot to System”.

⚠️ Note: If after resetting the phone requires the username and password from Mi Account, then the “Find Device” function was previously activated in the Xiaomi settings. In this case, you will need to unlock through the official website (see Method 4).

If Redmi 7A previously had USB debugging enabled (Settings → About Phone → MIUI Version → 7 Tap → Developer Settings → USB debugging), you can try to delete the password file via ADB.

Instructions for Windows:

If the commands are correct, the phone will unlock after the restart. If not, try an alternative method:

adb shell
