“Installation Monitor is on” on Xiaomi TV: what it means and how to remove the inscription

Why does the screen of Xiaomi TV appear the inscription “Installation Monitor is on”?

You turned on your Xiaomi Mi TV, and instead of your desktop, you saw a black screen with a white "Installation Monitor Enabled" sign that says, "Installation Monitor Enabled" -- not a system failure, but a special diagnostic mode that activates under certain conditions, most often after a failed firmware update, reset or incorrectly shut down the device.

The installation monitor mode is a tool for engineers and service centers to track the boot process, check file integrity and detect errors at a low level. It is useless for the average user, but it does nothing harmful: the TV will not break if left in this state.

In this article, we will discuss:

• 🔍 Reasons for activation of the mode and what it checks
• 🛠️ Ways to exit the installation monitor (from simple to complex)
• ⚠️ What can not be done to avoid aggravating the problem
• 📱 Features for different Xiaomi models (Mi) TV 4/5, A Pro, QLED etc.)

What does the “Installation Monitor” check on Xiaomi TV?

Installation Monitor starts automatically if the system detects potential problems in:

• 📁 Firmware Integrity – Checks the checksums of system files
• 🔄 Update process – tracks the stages of installing a new version of the software
• 🔌 Connecting modules – tests communication with Wi-Fi, Bluetooth, ports HDMI
• 💾 EMMC Memory – scans for broken sectors

You see not just a static text on the screen, but a real-time download log, and if you look closely, you can see a flashing cursor or lines of code appearing (e.g., [OK] Check partition: system or [FAIL] Verify boot.img) That's normal, because that's how the TV reports the diagnosis.

Usually, the mode lasts from 30 seconds to 5 minutes, after which the device either restarts to normal mode or hangs on this label.

The main reasons for the appearance of the inscription

There are several reasons why the installation monitor might work, and here are the most common ones:

The most common situation is a power failure during an upgrade, for example, if the TV is plugged into a UPS outlet and the lights in the house are turned off, in which case the system does not have time to write new files, and the next time it turns on, the diagnostics automatically start.

Less commonly, the problem is caused by hardware malfunctions, such as a worn memory, a damaged power connector, or an unstable power supply, and if the label appears even after a successful flashing, it is worth checking the iron.

💡

If your Xiaomi TV often loses Wi-Fi connection during upgrades, connect it to your router via an Ethernet cable, which will reduce the risk of failure.

How to remove "Installation Monitor is on": step-by-step instructions

Try the techniques in order from simple to complex. Start with a soft reboot, and only if it doesn't work, move on to reset or flash.

Method 1: Forced resetting

Sometimes the system gets stuck in the diagnostic phase, when there's actually no error, and a simple reboot will help.

1. Press and hold the power button on the remote (or TV body) for 10-15 seconds.
2. Wait until the screen goes out, then release the button.
3. Turn on the TV again with the power button.

If you see a Mi logo or an Android TV, you've solved the problem. If you don't, you can move on to the next one.

Method 2: Reset via service menu

On some Xiaomi models (such as the Mi TV 4S or A Pro), you can call a hidden recovery menu:

Turn off the TV for 1 minute.

Press the remote at the same time Menu + Back and hold

Turn the TV on without releasing the buttons.

Wait for the Recovery menu to come out.-->

From the recovery menu, select Wipe data/factory reset (use volume buttons for navigation and OK for confirmation).

⚠️ Warning: This method removes all installed apps and settings, and your Google or Mi Account data will remain, but you will have to reconfigure your Wi-Fi and personal settings.

Method 3: Update the firmware via USB

If the reset didn't work, it's likely the firmware is damaged, in which case you need to reinstall it manually.

1. Download the official firmware for your model from the Xiaomi support site (Firmware section).
2. Unpack the archive and copy the update.zip file to a flash drive formatted in FAT32.
3. Put the flash drive in. USB-TV port (preferably in the USB 2.0 if any).
4. Press on the Menu + Back remote, turn on the TV and hold the buttons until the update menu appears.
5. Select Update from USB and wait for the process to be completed (about 5-10 minutes).

After a successful update, the TV will restart automatically. If the process is stalled in the Verifying update package, try another flash drive or repeat the steps.

Features for different models of Xiaomi TV

The algorithm for exiting Installation Monitor may vary depending on the series of TVs.

Mi TV 4/4S/4A (2018–2020)

On these models, double reset often helps:

1. Reset via the service menu (as in Method 2).
2. Once you reboot, go back to the recovery menu and select Wipe cache partition.
3. Reboot the TV.

Mi TV 5/5 Pro/Q1/Q2 (2020–2022)

These TVs are sensitive to the firmware version, and if an Error 7 or Error 20 error appears after a USB update, you have downloaded the wrong build, check the exact model name on the documents or on the back sticker (e.g. L55M6-6ARG).

Mi TV A Pro/P1 (2021–2023)

On newer models with Google TV, the installation monitor mode may appear due to a conflict with the apps.

• 🔌 Turn off the TV for 30 minutes (full discharge of capacitors).
• 📵 Extract everything USB-memory-card.
• 🔄 Reboot through the button on the body (not remote!).

If nothing helps, use the firmware via Fastboot (instruction below).

Fastboot Flashing (Advanced Method)

This is the last resort if other options don’t work: you’ll need a computer with ADB and Fastboot drivers installed, and the original USB-A cable – USB-A (or adapter).

Warning: Mistakes can lead to a total loss of warranty and turn the TV into a brick. Use this method only if you are confident in your skills!

Download the official firmware with the extension.tgz

Install Mi Flash Tool on PC

Connect the TV to your computer via USB (OTG) port

Start the TV in Fastboot mode (Menu button) + Nutrition)-->

Step-by-step:

1. Unpack the archive with the firmware in a folder without spaces (for example, C:\MiTV_Firmware).
2. Launch the Mi Flash Tool, press Select and specify the path to the firmware folder.
3. Connect the TV to your PC via USB-OTG (usually a side connector).
4. Press Menu + Power on your TV and hold on for 10 seconds until the Fastboot logo appears on the screen.
5. In the Mi Flash Tool, press Refresh – the device must be determined.
6. Select Clean All and Lock mode and press Flash.
7. Wait until it's finished (about 5-15 minutes) and the TV will restart automatically.

⚠️ Attention: if the process is interrupted (for example, due to a power outage), the TV may stop turning on. Use an uninterruptible power supply (UPS)!

💡

Fastboot removes all data, including the associated Mi Account. After the procedure, the TV will be like new – you will need to reconfigure Wi-Fi and log in to your account.

What can not be done if there is a “monitor installation”

Some actions may make the problem worse or have irreversible consequences.

• ❌ Turn off power during the flashing of the indicator (this can damage the boot sector).
• ❌ Install custom firmware (like LineageOS) – this will take away your warranty and may cause hardware failures.
• ❌ Use informal tools like SP Flash Tool – They Are Not For Xiaomi TVs.
• ❌ Pressing random buttons in the service menu – this can lead to a reset IMEI or lock-in.

If you are not sure about your actions, you should contact the Xiaomi service center, in most cases, firmware recovery is free.
