How to remove the inscription on the lock screen Xiaomi Redmi Note 8T: from the owner to advertising

The lock screen of the Xiaomi Redmi Note 8T can display annoying words – whether it is the owner’s name, advertising slogan or system message. Most often, users are faced with automatically added text after updating MIUI, activating the device through Mi Account or installing third-party themes. Unlike flagship models, where this feature is easily disabled, on budget Redmi, the path to a solution is not always obvious.

Complicating the problem, different versions of MIUI (from MIUI 11 to MIUI 14) changed the lock menu, the options moved or disappeared. For example, in MIUI 12.5, the text on the lock screen was hidden in the submenu "Additional", and in MIUI 13 it was moved to the section "Personalization". We tested all the current methods on the Redmi Note 8T (models M1908C3XG and M1908C3XI) and identified 5 working methods - from simple to technically complex.

If the inscription appeared after resetting or buying a used phone, it is likely that this is a consequence of linking to the previous Mi Cloud account. In this case, the standard settings will not help - you will need to unlock through Fastboot or appealing for Xiaomi. The rest of the cases (advertising, owner name, system notifications) are solved software.

1. Delete the inscription through the standard MIUI settings

The safest way is to use built-in personalization options, which are suitable for removing the owner’s name, theme text or advertising slogans (for example, “Powered by”); MIUI"). Important: The method does not work if the inscription is added through ADB system-file.

The following is the case for MIUI 12-14:

1. Open the Settings → Lock screen.
2. Select Text on the lock screen (in some versions - Signature or Additional → Signature).
3. Turn off the slider or delete the text manually by clicking Edit.
4. Save the changes and restart the phone.

If the "Text on the lock screen" item is not on the menu, try an alternative path:

1. Go to Settings. → The phone.
2. Tap 5-7 times on the MIUI version line to activate the developer mode.
3. Return to the main settings menu, open Additional → for developers.
4. Find the option Lock Text and disable it.

⚠️ Note: Some firmwares may not have access to notifications on the lock screen after deactivating the text through Developer's, and reset the lock screen settings to Settings to return them. → Annexes → Application management → Settings → Warehouse → Clear the data.

Resetting themes and designs

The caption can be part of the set theme, for example, the themes from the Mi Theme Store often add watermarks or advertising lines, and even after the theme is removed, the text sometimes remains in the system's cache.

To completely clean the design settings:

1. Open Settings → Themes.
2. Choose a standard Default theme or MIUI.
3. Go to Settings → Applications → Application Management.
4. Find the Themes app, open its settings and click Clear Cache and Clear Data.
5. Reboot the phone.

If the problem persists, try resetting the lock screen settings separately:

adb shell pm clear com.android.settings

⚠️ Warning: This command will reset all personal lock screen settings, including widget layout and watch style. Backups won't help - the data is stored in the system cache.

3. Removal via ADB (for power users)

If the inscription is added at the system file level (for example, after manual editing) lockscreen_settings.db), help ADB. The method requires an unlocked bootloader and enabled debugging by USB.

Step-by-step:

1. Install ADB Tools on your PC.
2. Activate Developer Mode (see Section 1) and enable USB Debugging in Settings → Additional → For Developers.
3. Connect the Redmi Note 8T to your PC and follow the command: Adb devices (should display your device).
4. Enter the command to delete text: adb shell settings delete secure lock_screen_owner_info_enabled
5. Reboot the phone.

For MIUI 13+, an additional command may be required:

adb shell settings put global hide_lockscreen_owner_info 1

Critical: On some firmware after ADB-You're not able to access your fingerprint to recover it, go to Settings. → Passwords and security → Fingerprint and add fingerprints again.

4. Manual editing of system files (Root)

If previous methods failed, the inscription can be written in system files, and it will require a Root rights and a file manager with access to the root folder (for example, Root Explorer or Mixplorer).

Algorithm of action:

1. Get Root rights (for example, through Magisk).
2. Open the file manager and go to /data/system/users/0/
3. Find the file. lockscreen_settings.db Open it in the text editor.
4. Remove the lines containing: lockscreen_owner_info owner_info
5. Save the file, set resolutions 644 (rw-r-----).
6. Reboot the phone.

⚠️ Warning: Incorrect editing of system files can lead to bootloop ( looped reboot).Before changes, back up the file via TWRP Or OrangeFox Recovery.

5. Flashing the device (extreme case)

If the message appears after buying a used phone and is tied to someone else’s Mi Cloud account, the only reliable way is to completely flash through Fastboot or Recovery, which will also help if the text is added at the boot partition level (for example, after a failed overclocking of the processor).

Step-by-step instructions for Fastboot:

1. Download the official firmware for Redmi Note 8T (codename willow) from MIUI Download.
2. Unpack the archive in a folder with Fastboot tools.
3. Connect your phone in Fastboot mode (clip Power + Volume down when the device is off).
4. Run the command: fastboot flash all (add the -w key to complete cleaning).

For Recovery:

1. Download. ZIP-file with firmware and place it on SD-map.
2. Load into Recovery (clip Power + Volume up).
3. Select Wipe → Advanced Wipe and select Dalvik, Cache, Data, System.
4. Install the firmware through Install.

💡

Before you run the firmware, check the bootloader version with the fastboot getvar anti command. If the anti is 3 or higher, you will need an official unlocker from Xiaomi (the process takes up to 720 hours).

6. Appeal in support of Xiaomi

If the inscription is associated with the Mi Account lock (for example, after resetting the settings on the used phone), self-deletion is impossible - you will need proof of ownership.

1. Collect proof of purchase (check, purchase agreement, box with IMEI).
2. Take a picture of your phone’s IMEI (type *#06# or look at the sticker under the battery).
3. Please contact Xiaomi through: 🌍 Official website (Unlock Device section"). 📧 E-mail: support@xiaomi.com (Posted in "Mi Account Unlock Request"). 📞 Hotline phone (for Russia: 8 800 700 02 06).

The timeframe for processing the request is 3 to 14 days, and if approved, you will be sent an unblock instruction via the Mi Unlock Tool.

💡

If the phone is bought by hand and the previous owner has not untied the account, the chances of unlocking are minimal, in which case the only way out is to buy the unlock code from third-party services (for example, UnlockJunky or MIUI Unlock), but this violates Xiaomi’s policy and is fraught with fraud.
