If your TV or other Xiaomi device suddenly stopped loading with the words “Black to Main Menu” on the screen, and sometimes even going into a “black screen” with a flashing indicator, you are not alone. This error has become a real headache for owners of smart brand equipment, especially after unsuccessful firmware updates or firmware failures. Unlike typical “hangs”, here we are talking about a critical failure of the bootloader, which blocks access to basic functions of the device.

In this article, we will examine in detail what lies behind the mysterious message, why it appears on Mi. TV, Mi Box or other Xiaomi gadgets, and most importantly, how to bring the device back to life without going to the service center. USB OTG — You'll find step-by-step instructions for any level of training, and if you have a problem after you update the software, we'll show you how to roll back to a stable version and avoid repeated failures.

What does “Black to Main Menu” mean on Xiaomi?

The words “Black to Main Menu” (sometimes “Black to mainmenu” or “Go to Main Menu”**) are an emergency message from the bootloader of Xiaomi devices, signaling that the main firmware cannot load correctly.

In most cases, the error is accompanied by:

• 📺 Black screen with white text (on Mi TVs) TV or Redmi Smart TV);
• 🔄 Cyclical reboot (the device turns on, shows the Xiaomi logo, then goes back to the black screen»);
• 🔴 Flashing red/orange indicator (on the Mi Box or Mi Stick consoles);
• ⚙️ Automatic transition to Fastboot Mode (unless the bootloader is blocked).

It is important to understand that this is not a hardware failure (for example, a motherboard failure), but a software failure, which is usually caused by:

• 🔄 Failed software update (interrupted or with errors);
• 🗑️ Damage to system files (for example, after resetting to factory settings);
• 🔌 Firmware conflict (if you tried to install custom software);
• 🛠️ Failure of the bootloader (for example, after unlocking the bootloader).

⚠️ Note: If the error occurred after manual firmware ADB or Fastboot, don’t try to flash the device again with the same files – this can aggravate the problem. First check the integrity of the downloaded firmware (compare hash amounts with official Xiaomi data).

The reason for the error: why is the device not booting?

To effectively eliminate Black to Main Menu, you need to understand what went wrong.

This is especially true for devices with Amlogic processors (such as Mi Box S or Mi). TV Stick, where the boot boot boot boot boot is sensitive to damage. On TVs with MediaTek processors (e.g. Mi Mi). TV Q1/Q2) The error may be accompanied by a code E0001 or E0003 — This indicates damage to the system partition.

First steps: What to do if the device does not boot?

Before you start complex firmware manipulations, try basic recovery methods that help 30-40% of the time, especially if the failure is caused by a temporary software conflict.

1. Hard Reset (Hard Reset)

Most Xiaomi devices have a hidden reset button (usually located on the back or under the lid) to perform the reset:

1. Turn the device off the power.
2. Press and hold the reset button (use a paper clip or toothpick).

• 🔄 Use the original cable and power supply (especially relevant for Mi) TV Stick).
• 📺 If you are talking about TV, check the connection. HDMI-CEC (Sometimes conflict with other devices causes failures).

⚠️ Warning: If the device fails again after reset, do not repeat the procedure many times, which can damage the flash memory.

Flashing through USB OTG: step-by-step

If the basic methods don't work, you'll have to reinstall the firmware manually. For Xiaomi devices, it's done through a device. USB OTG (For TVs, or Fastboot, let's look at both.

Method 1: Firmware Xiaomi TV through USB

You'll need:

• 📁 Official firmware for your model (download from Xiaomi website or forum) 4PDA).
• 📇 USB-storage device FAT32, volume).
• 🔌 Cable OTG (flash-drive).

Steps:

1. Download the firmware (file with the extension.zip or.pkg) and rename it to update.zip.
2. Copy the file to a formatted flash drive.
3. Connect the flash drive to the TV through USB OTG.
4. Turn on the TV while holding the Menu + Volume + on the remote to enter Recovery.
5. Select Apply update from USB → specify update.zip file.
6. Wait until the installation is complete (do not turn off the power!).

Method 2: Firmwareing Mi Box via Fastboot

For consoles Mi Box or Mi Stick will require a PC with drivers installed ADB and Fastboot:

1. Download fastboot firmware for your model (for example, mi_box_s_2.1.79_fastboot.zip).
2. Unpack the archive in a folder on your PC.
3. Connect the Mi Box to the PC via USB, Holding the Reset button (to log in to Fastboot).
4. Open the command line in the firmware folder and do:

fastboot flash boot boot.img


fastboot flash system system.img




fastboot flash recovery recovery.img




fastboot reboot

💡

If the device fails again after running through Fastboot, try rolling back to an earlier version of the software. For example, for the Mi Box S, firmware 2.1.79 is stable, and versions older than 2.2.100 may contain bugs.

Firmware rollback: how to return the old version of the software?

If the "Black to Main Menu" error appears after an automatic update, the best solution is to roll back to the previous firmware version. TV, where new updates sometimes contain critical bugs (e.g., in versions) MIUI TV 3.0 for 2020–2021 models.).

How do you find the old firmware?

• 🌍 Xiaomi's official archive: bigota.d.miui.com (see model code, for example, l55m6-5ar for Mi TV 55").
• 💬 Forum 4PDA: In your model’s themes, you usually have archives with older versions.
• 📁 Cloud storage: Users often share firmware backups (e.g. on Google Drive).

Instructions for rollback:

1. Download the desired firmware version (for example, MIUI TV 2.1.5 instead of the problem 3.0.1).
2. Rename the file to update.zip and place it on the flash drive.
3. Log in to Recovery (as described above) and select Apply update from USB.
4. After installation, run the Wipe cache and restart the device.

⚠️ Note: Firmware rollback on Mi Box or Mi TV Stick can lock the bootloader if the new version of the software updates it, in which case you will need to unlock through the Mi Unlock Tool (only for accounts associated with the device!).

Hardware reasons: when firmware does not help

If all software methods have been tried, but the Black to Main Menu error persists, the problem may be in the hardware.

• 💾 Flash memory damage (e.g., wear of eMMC cells after repeated overwriting).
• 🔌 Power controller malfunction (TV turns on but cannot read memory stably).
• 🔥 Chipset overheating (relevant to Mi Box, which often operate in enclosed spaces).
• 🛠️ Oxidation of contacts (for example, after moisture is ingested).

How to diagnose a hardware malfunction?

• 🔍 Check if the device heats up when you try to turn on (if the case is hot - it is possible to overheat the chipset).
• 🔊 Listen to if there are clicks or squeaks when connecting the power (may indicate problems with capacitors).
• 📡 Try connecting the TV to another power source (e.g. via UPS) – if the error disappears, the problem is in the network.

If you suspect a hardware breakdown but don't have soldering experience, you should contact the service, but you can fix some problems yourself:

• 🔧 Replace thermopaste (relevant for Mi Box that overheat).
• 🧹 Cleaning contacts with alcohol (if the device has been in a wet environment).
• 🔄 Flush memory soldering (requires special equipment).

💡

If Xiaomi TV after turning on emits a double beep and goes into the "black screen", it almost always indicates damage to the flash memory, in which case the firmware will not help - you need to replace the chip or motherboard.
