How to Reboot Xiaomi Mi TV 4S: A Complete Problem Solving Guide

Modern Smart TVs, including the popular Xiaomi Mi TV 4S, are complex computing devices that run on the Android operating system. Like any computer or smartphone, this TV requires a reboot from time to time to properly work the software components. Users often face situations when the interface begins to react with a delay, applications stop running or the image completely disappears when the sound is working.

Unlike the old kinescopic models, where switching off the switch was the only way to "cure," digital devices require a more delicate approach. A conventional disconnection from the network can damage the file system if background recording or updating processes are underway at that point, so it is important to understand the difference between a soft reset and a forced power outage.

In this article, we will discuss in detail all the available methods for restarting your Mi TV 4S. We will look at the standard interface tools, working with the remote control, as well as more advanced ways through debugging over USB. This knowledge will help you quickly bring the device back to life without calling the wizard.

Reboot through the system’s software menu

The safest and most appropriate way to restart Android TV is to use the operating system’s built-in features, which ensure that all active processes are completed correctly and the app cache is cleared before shutting down, and you need to unlock the screen if the power saving feature is enabled and go to the main screen.

Using the remote, go to the top right corner of the screen, where the gear icon is located. This is the entrance to the Settings section. Depending on the version of the firmware (MIUI for TV or pure Android TV), the interface may vary slightly, but the logic remains the same. You need to find the partition responsible for managing the device.

⚠️ Warning: Do not use Fast Boot if your goal is to fix a software failure, which only puts the TV into sleep mode, keeping the processes in memory, which does not solve the problem of freezes.

The next step is to make sure that the algorithm is different, depending on the specific version of the interface, and most of the time, the path is: Settings → Device → About TV → Reboot. If you don't have that option in the quick access box, look for "Switch off" and select "Reboot" instead of "Switch off."

After selecting the command, the screen will go out, and after a few seconds the Mi logo will appear. It can take from 30 seconds to 2 minutes to download depending on the number of applications installed and the amount of accumulated system error.

Hardware method: use of remote control

If the Xiaomi Mi TV 4S interface responds to commands but the menu doesn't open, you can use a button combination on the remote, which is the analogue of a keyboard combination on a computer, allowing you to call the system menu or force the interface to restart.

The original Bluetooth Mi Remote often uses (long press) power buttons. If you hold the power button for 5-10 seconds, a dialog box should appear on the screen suggesting that you turn off or restart the device. If a standard short press blocks the screen, a long press will initiate a deep restart.

There is also a versatile combination for Android TV that can work on Mi Box and Xiaomi TVs:

• 🔘 Press and hold the Home and Back buttons (or Menu) for 10 seconds at the same time.
• 🔘 If the TV reacts, it will try to restart the launcher (shell).
• 🔘 In some cases, long pressing (about 15 seconds) of the switch off button on the TV body itself helps if the remote does not respond.

It is important to note that the infrared remote (if you use a universal) may not support deep reboot functions, as they are tied to the Bluetooth command protocol, in which case it is better to use a menu or physical disconnection.

Reset Power (Hard Reset Power)

When the software methods are powerless and the Xiaomi Mi TV 4S is completely "hanging" (the image is frozen, the sound is gone or repeated cyclically), there is a method of physical power reset, which is similar to removing the battery from a smartphone and should only be used in extreme cases.

The idea is to completely de-energize the control board, but simply pulling the cord out of the socket is not enough. In modern power units, residual currents remain, and the capacitors retain a charge that keeps the memory active (RAM) The following sequence must be followed:

1. Remove the power cord plug from the socket.
2. Wait at least 60 seconds. This is critical for discharge of capacitors.
3. While the TV is offline, press and hold the physical switch on the case (not the remote) for 15-20 seconds.
4. Turn the TV on and start it with a button.

⚠️ Attention: Frequent use of forced power outage can lead to flash memory degradation and loss of system files. Use this method only when the system fails to respond completely.

Once turned on, the system can check the file system, which will take longer than a normal boot. Do not interrupt this process. If after this procedure, the TV loads to the logo and restarts again (bootloop), the problem may be deeper than a simple software failure.

Full reset to factory settings

If a normal reboot doesn’t help fix bugs, lags, or connection issues, Factory Reset may be needed.This operation brings the Xiaomi Mi TV 4S back to the “out of the box” state, removing all user data, accounts, and installed apps.

Before starting the procedure, be sure to synchronize important data or write down passwords from Wi-Fi. Reset can be done in two ways: through the settings menu or through Recovery Mode if the system does not boot.

Menu method (if the TV is turned on):

• 🗑️ Go to Settings. → The device → Reset.
• 🗑️ Select "Reset" or "Factory Reset".
• 🗑️ Confirm the action by entering a pin code (usually 0000 or 1234) or agreeing to the warning.

If the menu is not available, use Recovery Mode. To do this, on a TV turned off (or disconnected from the network, then turned on to the network), you need to quickly press the combination of buttons on the remote. On different Xiaomi models, this can be the Back button. + Down button or menu button + Up button held at the moment of power on. In the menu that appears, select Wipe Data/Factory Reset and confirm the action.

Using ADB for Advanced Reboot

For users familiar with the technical aspects of Android, there is a way to reboot through ADB (Android Debug Bridge) debugging, which allows you to send a command to restart system processes or the entire OS remotely, which is useful if the interface is blocked, but the network is working.

First, activate the developer mode. Go to Settings → About TV and quickly click on Build Number 7 times. After the message "You became a developer" go to the Developer menu and turn on "Debugging by USB".

adb connect 192.168.1.XX:5555


adb shell reboot

Instead 192.168.1.XX set up IP-The address of your TV, which you can find in the "About Network" section, the adb shell reboot command initiates a regular software reboot, ADB It may not be possible to respond because it requires the main process of the system to work.

💡

Find out. IP-The address of the TV in advance and write it down in a notebook, which will allow you to connect to the device through the ADB Even if the screen is not responsive to the remote, the network is active.

Comparison of methods and elimination of frequent problems

Not all reboot methods are equally effective for different types of problems. Below is a table that will help you choose the best way to solve a specific malfunction Xiaomi Mi TV 4S.

A common problem is that you may not work properly after a firmware update, in which case the system cache may conflict with new files, and after an update, it is always recommended to perform one full reboot through the menu, even if the TV is working normally.

It is also worth mentioning the problem with external drives. USB-The port has a hard drive or flash drive with a lot of files, the TV can be turned on or hanging for a long time at start. USB-pre-reboot.

💡

Regular reboots (once every 1-2 weeks) extend the life of the Smart TV, freeing RAM from fragmented data and stopping background processes that the user does not use.
