How to remove the inscription from the lock screen on Xiaomi Redmi 8: all working methods

The inscription on the lock screen Xiaomi Redmi 8 — a common problem that users face after buying a used phone, resetting settings or installing custom firmware. This can be the name of the previous owner, advertising slogan, a message from the operator or even a system notification that is not removed by standard methods. In some cases, the text interferes with unlocking, in others — just spoils the appearance.

In this article, we will look at all the current methods of deleting inscriptions, from simple (via phone settings) to advanced (using ADB and editing system files). It is important to understand that not all methods are universal: some work only on MIUI stock firmware, others require an unlocked bootloader, we will specify the limitations of each method and warn against typical errors.

If you are unsure of your technical skills, start with the first two sections, which describe safe solutions without risking damage to the system.

1. Delete the inscription through the lock screen settings

The most obvious and safe way is to check the standard MIUI settings, and in most cases, the label appears because of the activated "Text on the Lock Screen" function, which can be manually disabled.

• 📱 The phone was not re-interfaced (it is official). MIUI).
• 🔓 You have access to settings (not locked by password).
• 📛 Added via system tools, not third-party software.

Instructions:

1. Open the Settings → Lock screen.
2. Select Text on the lock screen (in some versions of MIUI it may be called Signature or Additional Information).
3. Remove existing text or disable the Show Text slider.
4. Save the changes and restart the phone.

If this item is not on the menu, then the inscription is added in another way (for example, through ADB or a third-party application).

⚠️ Attention: On firmware MIUI 12.5+ The path to settings may be different. If you don't find a section, search by settings (the magnifying glass icon in the upper right corner).

2. reset the lock screen settings to factory

If the label appears after a system update or installing a third-party launcher, a partial reset of the lock screen settings will help, this method does not affect user data (photos, messages, applications), but will return all visual settings to the state out of the box.

How to perform the reset:

1. Go to Settings → About the phone → Reset settings.
2. Select Reset the lock screen settings (not to be confused with a full reset!).
3. Confirm the action and wait for the reboot.

After the procedure, check if the inscription has disappeared. If not, the reason lies deeper - perhaps the text is written in system files or added through ADB.

Make sure your phone is at least 50% charged

Save important data (contacts, photos)

Remember the password from the Mi Account (required for re-authorization)

Disable two-factor authentication (if enabled)

This method often helps after installing custom themes from the Mi Theme Store, which can add watermarks or advertising slogans to the lock screen.

3. Delete the inscription via ADB (for advanced users)

If standard methods didn't work, the inscription could have been added via ADB (Android Debug Bridge), which is true for hands-on phones where the previous owner has customized personalized text, and you'll need a computer to remove it and USB debugging enabled.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Press 7 times on the MIUI Version until the notification appears.

USB debugging

Settings → Additional → For Developers

ADB

adb shell settings delete secure lock_screen_owner_info_enabled

Reset the device.

If the team doesn’t work, try an alternative:

adb shell settings put secure lock_screen_owner_info_enabled 0

⚠️ Attention: Use ADB Incorrect commands can disrupt the system. Before executing, make sure that Xiaomi drivers are installed on the PC and the cable supports data transfer (not only charging).

4. editing system files (only for unlocked bootloader)

The inscription can be spelled out in MIUI system files, for example in /system/media/theme/default/com.miui.system.xml or /data/system/locksettings.db. These can only be changed on a phone with an unlocked bootloader and root access.

Instructions for experienced users:

1. Install a file manager with root support (such as Root Explorer or Mixplorer).
2. Go to /data/system/ and find the locksettings.db file.
3. Open it in the text editor and find the lines with owner_info or lockscreen_text.
4. Delete or edit the values, save the file, and reboot the phone.

Step-by-step:

1. Download the official firmware for Redmi 8 (codenamed olive) from MIUI Download.
2. Unpack the archive and place the update.zip file in the root of the phone’s memory.
3. Go to Settings → About the phone → System update.
4. Click on the three dots in the upper right corner and select Select the firmware file.
5. Please specify the path to update.zip and confirm the installation.

After flashing, the phone will restart and return to factory settings, and all user data (including the inscription on the lock screen) will be erased.

💡

Fastboot flashing (using the Mi Flash Tool) is more reliable, but requires an unlocked bootloader. Use it if update.zip doesn't work.

6.Verification for viruses and malware

Sometimes a sign on the lock screen is added by viruses or ad modules installed through third-party apps, this is true if the text appeared suddenly and contains links or calls to action (for example, "Your phone is infected!").

How to check and delete:

1. Install an antivirus (such as Malwarebytes or Dr.Web Light).
2. Scan the system for threats.
3. Check the list of installed apps in Settings → Apps. Uninstall suspicious programs (especially with Overlay rights over other windows).
4. Turn off administrator rights for unknown applications in Settings → Passwords and Security → Device Administrators.

If the virus blocks access to settings, try booting in Safe Mode:

1. Press the power button before the off menu appears.
2. Hold your finger on Turn off until you are prompted to switch to Safe Mode.
3. In this mode, remove malicious applications.

7. Contact the Xiaomi Service Center
