You turned on your Xiaomi Mi TV or your Mi Box, and instead of your desktop, you saw a blue screen that said, "Main Menu" and a list of obscure items? This bug is one of the most common firmware failures on Xiaomi devices, and it can occur after an update or for no apparent reason. 90% of the time, the problem is solved without going to the service center, but it's important to act consistently so as not to make things worse.
The Main Menu screen is a low-level recovery menu that appears when the Android TV system cannot boot normally. It signals a boot partition damage, firmware conflict or hardware failure. In this article, we will discuss all the possible causes of Main Menu on Xiaomi (from a banal failure to critical eMMC errors), and also give step-by-step recovery instructions from the simplest reset to flashing over USB.
Before you start the repair, answer two key questions:
- Does the Main Menu appear once when you turn on, after which the device boots normally?
- Do you see items like Reboot, Wipe data, or Apply update?
The answers depend on how serious the problem is and which recovery method to choose.
1 What is Main Menu on Xiaomi and why does it appear
The Main Menu screen (sometimes called Fastboot Mode or Recovery Mode) is an emergency bootloader mode that activates when:
- 🔄 Firmware damaged – for example, after a failed update “over the air» (OTA) orthose.
- 🗄️ Data partition failure – file system damage, application conflict, or virus.
- 🔋 Hardware problems – wear of eMMC memory, controller failure or motherboard malfunction.
- ⚡ Improper shutdown – if the device is turned off during the upgrade or the power is abruptly turned off.
On Xiaomi Mi TV (including Mi TV 4A/4S/4X/5/5X) and Mi Box S/4K Main Menu consoles, it looks like a blue or black screen with white text and points:
Reboot system now
Apply update from ADB
Apply update from USB
Wipe data/factory reset
Wipe cache partition
...Critical error: if instead of Main Menu you see No command or the screen flashes and reboots, this is a sign of a “brick” (complete firmware failure), and you will need to flash through fastboot.
2.The first steps: diagnosis and soft reset
Before you start radical measures, perform a diagnosis:
- Check the remote: Sometimes the Main Menu comes from behind a pressed Menu or Home button on the remote. Remove the batteries for 30 seconds.
- Turn it off. USB-Devices: flash drives, hard drives or keyboards may conflict with the bootloader.
- Try another power cable: unstable voltage can cause failures when booting.
If the problem has not gone away, do a soft reset (does not delete data):
Select Reboot system now (use volume buttons for navigation, OK for selection)
If the device is loaded back into Main Menu → proceed to the next step
Check if an error occurs after a 5 minute disconnection
-->
If the Xiaomi logo appears after the reboot and then Main Menu again, this is a sign of a cyclic reboot, and you will need to reset or firmware.
💡
On some models (for example, Mi TV 5 Pro) to exit from Main Menu, you can hold the Power button on the case for 10-15 seconds until completely switched off, then turn it on again.
3. Reset to factory settings (Wipe Data)
If a soft reset doesn’t work, the next step is a full reset (Wipe Data), which will delete all installed apps, accounts and settings, but will keep the system running. Importantly, on Xiaomi TVs, the reset does not affect files on the internal drive (photos, videos), but deletes application data.
Instructions:
- In Main Menu, select Wipe data/factory reset (± volume buttons).
- Confirm the selection (usually Yes – Delete all user data).
- After reset, select Reboot system now.
It takes 2-5 minutes. If you reset,
- ✅ The device booted normally. → Problem solved (configure it again).
- ❌ Main Menu is back again. → Firmware damaged, needing reflashing.

4. Firmware via USB: step-by-step instructions
If the reset didn't work, you'll need a hand firmware.
- 🖥️ Computer with Windows/macOS/Linux.
- 💾 Empty flash drive (FAT32, 32GB).
- 📄 Official firmware for your model (download from Xiaomi website).
Important! The firmware must match the exact model of your device. For example, the Mi TV 4A 32 and Mi TV 4A 55 can have different files!
Firmware steps:
- Download the firmware (file with.zip extension) and unpack it.
- Copy the firmware file (usually update.zip) into the root of the flash drive.
- Put the flash drive in. USB-set-top.
- In Main Menu, select Apply update from USB → specify update.zip file.
- Wait until the device is finished (don’t turn off the device!).
- After installation, select Reboot system now.
Firmware time: 5 to 20 minutes. If the process is interrupted, the device may stop turning on!
💡
USB firmware is the most reliable way to recover, but requires the correct firmware file. Never use files from third sites (risk of "brick" or viruses).
5. Firmware via Fastboot (for power users)
If USB-The firmware didn't work (e.g., because of a damaged recovery partition), you'll need firmware through Fastboot mode, which is more complex and suitable for users familiar with the command line.
What you need:
- 🖥️ Computer with drivers installed ADB/Fastboot.
- 🔌 Cable USB-A → USB-A (PC-connector).
- 📂 Firmware in.tgz format (downloaded from the official website).
Instructions:
- Unpack the firmware in the folder from fastboot.
- Connect the TV to your PC by holding the Power + Menu button (to log in to Fastboot).
- Run the command line and run: fastboot flashall (or alternately swipe through each section: fastboot flash boot.img, fastboot flash system.img, etc.).
- Upon completion, type in fastboot reboot
⚠️ Attention, the wrong commands in Fastboot can permanently shut down your device.
6. Hardware reasons: when firmware does not help
If all software methods have been tried and Main Menu still appears, the problem may be in the hardware:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Main Menu appears after 5-10 minutes of work | Overheating of an eMMC chip or processor | Cleaning from dust, replacing thermopaste |
| The device can't see. USB-flash-drive | Malfunction USB-port-controller | Multimeter port check, soldering |
| Main Menu with E:Can't mount /cache error | Damage to eMMC memory | Replacement of memory chip (requires soldering station) |
| Screen blinks, no image | Maternity board malfunction | Diagnostics in the service |
The most common hardware problem is memory wear and tear on the eMMC. On cheap Xiaomi Mi TV 4A models (especially in 2018-2019), the memory controller fails after 2-3 years of heavy use, in which case only a replacement chip will help.
💡
Before repairing, check if the warranty period has expired. If the device is less than 2 years old, contact the official Xiaomi service - repairs can be free.
7 How to Avoid Main Menu Reappearance
To prevent the problem from returning, follow simple rules:
- 🔄 Update your firmware only through official channels (do not use custom firmware).
- ⚡ Use an uninterruptible power supply (UPS) – this will save you from failures when power outages.
- 🗑️ Do not fill the memory “to the end” – leave at least 10% of the free space.
- 🛠️ Make a cache reset every six months (in Main Menu, select Wipe cache partition).
⚠️ Attention! If your Xiaomi TV overheats frequently (the body is hot to the touch), install additional cooling or move it to a more ventilated location.
