If your Xiaomi TV (Series Mi) TV 4/4A/4S/5/5X/Q1/Q2 or Redmi Smart TV) It's a screen that says "Main Menu Reboot" and doesn't respond to the remote or buttons, which is a critical bug in the firmware, and it's most common to have a problem after a software update fails, a power failure during booting, or a system file conflict. Unlike a normal freeze, this bug blocks access to even basic functions, turning the TV into a brick».
In this article, we will look at all the possible causes of Main Menu Reboot, from simple (e.g., a faulty HDMI cable) to complex (damaged firmware), you will receive step-by-step instructions on how to restore the TV from reset to manual firmware via USB, and how to avoid repeated failures. Importantly, some methods require technical skills, but most problems are solved without going to the service center.
What does the Main Menu Reboot Error mean?
The words “Main Menu Reboot” (sometimes “Main Menu Rebooting...”) appear when the Xiaomi TV system cannot load the main menu correctly due to:
- 🔄 Interrupted updates – if the TV is turned off from the outlet or the power is lost during the installation of the firmware.
- 💾 Damaged memory partition – read/write errors in the internal drive (most often on models with eMMC).
- 🔌 Hardware conflict - faulty HDMI-port, connected device (set-top box, sound bar) or damaged cable.
- 🦠 Virus or failure in Launcher – rare, but possible when installing third-party APK.
Technically, this is an emergency mode that the TV enters when it is impossible to load the graphical interface. On some models (Mi TV 5 Pro, Q2 75), instead of text, a black screen with a flashing indicator or the Xiaomi logo can be displayed.
First steps: what to do before the reset?
Before you start taking drastic measures (such as flashing), check for simple reasons that can cause a false positive:
- Turn off all external devices: remove HDMI cables, USB cables, optical audio cables, and sometimes conflict with the Apple TV or NVIDIA Shield system will block the menu from loading.
- Check power: connect the TV to another outlet (no extension/filters). On Mi TV 4S models and older, the failure can be caused by unstable voltage.
- Reset the remote: take out the batteries for 30 seconds, then insert back in. If the remote is faulty, the TV may "hang" during the initialization stage.
- Wait 10-15 minutes: In some cases, the system recovers after a long wait (relevant for models with Android TV 9+).
If after these actions the error remains - move to deeper methods of diagnosis.
💡
On Xiaomi TVs with Android TV 10/11 (such as Mi TV Q1), the “Main Menu Reboot” error may appear due to a failure in the Google Play Services service. Try to turn off the Internet for 5 minutes (take out the Ethernet cable or turn off the Wi-Fi in the router), then reboot the TV with a button on the case.
Resetting settings through the service menu
If the TV reacts to buttons (e.g., turns on/off) but doesn't load the menu, try a soft reset via a keyboard combination.This method works on most Xiaomi and Redmi models:
- Turn off the TV with a button on the case (not the remote!).
- Press the buttons on the remote at the same time: Menu (⋮) + Back up (←) + Home (🏠) Hold them for 10-15 seconds until the service menu appears.
- From the menu, select Wipe Data/Factory Reset (use volume buttons for navigation, OK button for selection).
- Confirm the reset and wait for the reboot (can take up to 5 minutes).
Important: this method doesn't remove the firmware, but it resets all settings, accounts, and installed applications. If the error is caused by corrupting system files, resetting won't help, you'll need to flash it back.
What to do if the service menu is not opened?
Manual flashing over USB
If the reset didn't help, it's likely the firmware is damaged, and then you'll need to install the official software manually through the computer. USB-This method is suitable for all Xiaomi models TV, but requires strict adherence to instructions.

Hardware causes of error
If the software methods didn't work, the problem could be the hardware.
| Malfunction | Signs. | Decision |
|---|---|---|
| Damaged Memory (eMMC) | The TV is cyclically restarted, does not save settings | Replacement of memory chip (requires soldering work) |
| Faulty power supply | Spontaneous shutdowns, indicator flickering | Checking capacitors, replacing the block |
| Oxidized plume contacts | Artifacts on screen, error appears after heating | Cleaning contacts with alcohol or replacing the plume |
| Faulty. HDMI-port | Error occurs when connecting devices | Replace the port or disable the problem connector |
🔧 Self-repair is possible only if you have experience with electronics:
- 🔬 Multimeter (coupling of supply chains).
- 🔥 soldering station (to replace eMMCs or capacitors).
- 📸 Thermal imaging (to search for overheating components).
⚠️ Attention: On Xiaomi models TV Android TV 11+ (Like Mi. TV Q2) If you replace the eMMC, you'll need to flash a unique serial number through service software!
Preventing the Main Menu Reboot Error
To avoid repeated failures, follow these guidelines:
- 🔌 Use UPS: Connect your TV through an uninterruptible power source (especially relevant for regions with unstable voltages).
- 🔄 Update your firmware over cable: Use Ethernet, not Wi-Fi, for critical updates.
- 🚫 Do not install third-party launchers: they may conflict with system software.
- 📦 Regularly reset the cache: in the Settings menu → Annexes → Clear the cache.
On Redmi Smart TV X and later, the error can be triggered by automatic memory optimization.
- Go to Settings. → On TV.
- Click 7 times on the Software Version to activate the Developer Mode.
- Go back to Settings → For Developers and turn off Auto-Optimization.
