Method 1: Automatic Internet Update (OTA)

The easiest and safest method is to upgrade over-the-air, which is suitable for most users because it doesn't require technical skills. The TV finds and installs the latest stable version of the software.

To start the process:

1. Open the settings (cog in the upper right corner of the screen).
2. Go to the section About TV → Updating the system.
3. Click Check Updates. If a new version is available, the Download and Install button will appear.
4. Confirm the installation and wait for the restart (the TV will restart 1-2 times).

The whole process takes 10 to 25 minutes depending on the speed of the Internet. Do not press buttons on the remote or turn off the power while the download indicator is on the screen (white progress bar with the Mi logo).

💡

If the update is not long, try changing it. DNS-server on the TV. Go to Settings for that. → Network → Setting up IP → DNS and enter 8.8.8.8 (Google) DNS).

Method 2: Manual firmware via USB (for power users)

If automatic updates are not available or you want to install a specific version of the software (for example, roll back to a previous build), use the manual method via USB. This method will also help if the TV is not turned on or is stuck in the boot cycle.

To start, download the official firmware from Xiaomi. It is important to choose a file exactly for your model! TV P1 55" (L55M7-7PRU) tagged p1_ru or p1_global. References to current versions:

• 🌍 Official Xiaomi website (global firmware)
• 🇨🇳 Support page (select region)
• 🔗 Third-party firmware archive (for older versions)

The firmware file will have the.zip extension and weigh about 1.2–1.8 GB: Don't unpack the archives! Just copy it to the root catalog. USB-- The storage device (not in the folder!) update.zip — It'll make it easier to find.

⚠️ Note: If after the scaling of the USB Xiaomi TV P1 stop turning on or show a black screen, but the power indicator is on, try repeating the process with another USB-Sometimes the problem is that the flash drive is incompatible with the port.

Method 3: Fastboot Firmware (for recovery from failure)

If the TV doesn’t respond to the remote, freezes on the logo or doesn’t turn on at all, it may require firmware via Fastboot mode.This method is more complex and requires a PC connection, but it is the only one who can “resuscitate” the device after serious crashes.

You'll need:

• 🖥️ Windows computer 10/11 and installed drivers ADB/Fastboot (You can download it here).
• 🔌 Cable USB-A — USB-A (PC-connector).
• 📁 Firmware in.tgz or.img format (see forums) 4PDA or XDA Developers with the tagged fastboot).

Step-by-step:

1. Unpack the archive with the firmware in a folder on the PC (for example, C:\p1_fastboot).
2. Open the command line (Win) + R → cmd) and go to the firmware folder: cd C:\p1_fastboot
3. Connect the TV to your PC with a USB-A-USB-A cable (the port on the TV is usually located on the side).
4. Press the Power button on your TV and hold it and connect the cable to your PC. Hold the button for 10-15 seconds until the Fastboot Mode appears on the screen.
5. In the command line, type: fastboot devices If the device is determined (the serial number will appear), continue. If not, install the drivers again.
6. Run the firmware command: fastboot flashall or (if the firmware file is called otherwise): fastboot flash boot.img fastboot flash system.img fastboot reboot

It takes 5-15 minutes. Upon completion, the TV will automatically restart. If the screen remains black for more than 10 minutes, turn off the power for 30 seconds and turn it on again.

5. Firmware rollback and factory settings restoration

Sometimes after the update, bugs appear: slows down the interface, applications (for example, YouTube or Disney+), sound disappears, in which case a rollback to the previous version of the software or a reset to factory settings will help.

For discharge:

1. Go to Settings → Device → Reset and Recovery.
2. Select Reset and confirm the action (you may need to enter) PIN-code).
3. The TV will reboot and return to the “out of the box” state.

If you need to revert to the old firmware:

1. Download the desired version of the software (see section 3) and save it to USB as update.zip.
2. Log in to Recovery Mode (Menu + Power buttons).
3. Select Wipe data/factory reset (this is a must, otherwise version conflicts are possible!).
4. Install firmware via Apply update from USB.

💡

Resetting to factory settings does not remove the firmware, but only cleans user data. If the problem is caused by the firmware itself (for example, a bug in the new version), reset will not help - you need a rollback or flashing.

⚠️ Attention: On Xiaomi TVs P1 Android-based TV 11 and later, after a reset, you may need to re-assign your Mi Account. If you forget your password, restore it in advance at account.xiaomi.com.

6. Custom firmware: pros and risks

Power users sometimes install informal firmware (like LineageOS or modified Android TV builds) to extend the functionality.

• 🎮 Install Google Play Store on Chinese TVs.
• 🔧 Unlock root access for deep system configuration.
• 🚀 Remove Xiaomi’s built-in apps (such as Mi Home or PatchWall).
• 📺 Add support for Dolby Atmos or HDR10+, If they are disabled in the stock firmware.

However, there are serious risks:

• ❌ Loss of warranty (Xiaomi does not repair custom firmware devices).
• ❌ Possibility of "bricking" (if the firmware is incompatible with iron).
• ❌ Lack of security updates (unofficial builds rarely updated).
• ❌ Problems with work DRM (Netflix support may be missing from the 4K).

If you still decide to experiment, look for firmware on proven resources:

• 🔗 XDA Developers (Segment Xiaomi Mi) TV).
• 🔗 4PDA (tagged [Custom ROM]).

Custom firmware installation requires unlocking the bootloader, which is done through the official Mi Unlock Tool, but Xiaomi may refuse to unlock for TVs (as opposed to smartphones).
