Linking a Mi Account account to a Xiaomi Mi TV 4S 43' (MCG3B) TV is often a problem when selling a device, transferring it to another user, or after resetting the settings. Even a factory reset via the menu doesn't always remove the account's binding, leaving the device locked to require the previous owner to enter the username and password. In this article, we'll discuss all the current ways to remove Mi Account from the MCG3B model, including official and alternative methods, as well as the risks of each approach.
Xiaomiβs Android TVs are a feature of deep integration of Mi Account services into security, which means that simply resetting through Settings β Reset is not enough: the account remains tied to the deviceβs hardware identifier. We tested all of the methods described below on firmware from 2023-2026, so the instructions are relevant for the latest versions of the software.
β οΈ Note: Deleting Mi Account without access to the original login/password may violate the warranty and result in a complete lock of the device. ADB or service teams require technical skills β errors in teams can βbrickβ the TV.
1. Official reset via TV settings
The safest way is to use the built-in features of the system if you have access to a tied Mi Account, a method that is suitable for preparing the TV to be sold or transferred to another user.
Step-by-step:
- Open Settings (cog in the upper right corner of the main screen).
- Go to the Accounts and Security section β Mi Account.
- Select the option to Delete your account (password may be required).
- Confirm the action and wait for the process to be completed.
- Return to Settings β Device β Reset settings and perform a full reset.
If the Delete account option is missing or blocked, it means that the TV is linked to the account through FRP (Factory Reset Protection), a reset protection mechanism, in which case alternative methods will be required.
Turn off the TV from the Internet (Wi-Fi/Ethernet)
Record the current screen and sound settings
Make sure you have a password from your Mi Account.
Connect the remote to the TV (check the batteries)

2.Reset via Recovery Mode
If Mi Account is lost but the TV is not blocked after reset, you can try removing the binding via Recovery Mode.This method works on firmware up to MIUI TV 3.0 (2022), on newer versions may require ADB.
How to Sign in to Recovery Mode on Xiaomi MCG3B:
- Turn off the TV with the remote control.
- Press the buttons Menu + Volume Down (Loudness decrease).
- Holding them, press the power button on your TV and hold all three buttons for 10-15 seconds until the Xiaomi logo appears.
From the Recovery menu, select:
Wipe data/factory reset β Yes
Wipe cache partition β Yes
Reboot system nowβ οΈ Note: On TVs with firmware newer MIUI TV 3.2 (release after March 2023) Recovery reset does not remove the Mi Account binding.

3. Delete Mi Account via ADB (for advanced users)
The Android Debug Bridge (ADB) method is the most reliable way to get around Mi Account locking, but requires a TV connection to a computer and knowledge of commands. It works on all versions of Xiaomi MCG3B firmware, including the latest 2026 updates.
What you need:
Step-by-step:
- Connect the TV to your computer via USB.
- Open the command prompt (cmd on Windows or Terminal on macOS/Linux).
- Enter the command to check the connection: Adb devices Should appear with the serial number.
- Follow the commands to delete your account: adb shell su pm uninstall -k --user 0 com.xiaomi.account pm clear com.google.android.gms reboot
Critical detail: if after the reboot the TV still requires the input of Mi Account, you need to repeat the process and additionally execute the command settings put global frp_state 0 shelled ADB.

4. bypass FRP-blocking through the service menu (for experienced)
If the TV is locked after a reset and requires Mi Account data entry, you can try bypassing FRP (Factory Reset Protection) through a hidden service menu, which does not work on all firmware, but often helps on devices with MIUI TV 2.0-3.5.
Instructions for circumventing FRP:
β οΈ Note: Service menu codes may vary depending on the region of the firmware (CN-version) this method often does not work - you will need firmware through Fastboot.
π‘
If the service menu doesn't open, try connecting the keyboard over USB and using Ctrl + Alt + T on the lock screen, which sometimes causes a command terminal to appear.
5. Firmware TV through Fastboot (last resort)
If all previous methods fail, you can completely flash your TV through Fastboot mode, which deletes all data, including Mi Account, but requires:
Step-by-step:
- Download the firmware for Xiaomi Mi TV 4S 43' (MCG3B) in.tgz format and unpack it.
- Turn off the TV and connect it to your computer via USB.
- Press on the Menu + Volume Down remote and, holding them, connect the power cable. The TV should go to Fastboot mode (black screen with the inscription Fastboot).
- Launch the Mi Flash Tool, select the unpacked firmware and press Flash.
- Wait for the process to be completed (10-15 minutes) and restart the TV.
Risks of the method:
| Problem. | Effects of consequences | Decision |
|---|---|---|
| Wrong firmware | The TV is not turned on ("brick") | Squeeze through EDL-service-centre |
| Interruption of the process | Damage to system partitions | Repeat the firmware from the beginning |
| Model inconsistency | Invalid image error | Download firmware specifically for MCG3B |
π‘
Fastboot firmware is the only way to guarantee that you will delete your Mi Account if other methods fail, but it is also the riskiest method that can cause your device to fail if you fail.
6. Contact Xiaomi Support
If you are unsure of your technical skills or your TV is locked after a failed reset attempt, the safest solution is to contact official Xiaomi support.
- π Accessing email linked to Mi Account (even if you donβt remember the password, support can help with recovery).
How to contact support:
- Write to chat or create a ticket describing the problem (specify the MCG3B model and the TV serial number).
The timeframe for reviewing the request is 3 to 7 days, and in most cases, support provides instructions to unlock or resets the account remotely.
