The easiest and safest method is an over-the-air update (OTA), which is suitable if your curtain is braking due to minor bugs, not serious system failures.

1. Open Settings → About the phone → System update.
2. Click Check Updates. If a new version is available, the system will prompt you to download it.

Method 2: Manual updates through Recovery

If automatic updates didn’t help or the system doesn’t see new versions, try installing firmware manually through Recovery.This method saves user data but requires pre-loading the correct firmware file.

Method 3: Complete Fastboot Firmware (for experienced)

If the previous methods didn't work, you're left with a complete Fastboot flash, which erases all data, but it's guaranteed to restore the curtain and the system as a whole, and you can only use it as a last resort.

Requirements:

• 🖥️ Windows computer (or Mac/Linux fixed ADB/Fastboot).
• 🔌 Cable USB (preferably original).

1. Unpack the firmware in a folder on your computer (for example, C:\MIUI\lavender_fastboot).
2. Turn off the phone and press Power + Volume down to enter the Fastboot (a hare in a hat-eared hat will appear).
3. Connect your phone to your PC and start the Mi Flash Tool (download here).

What to do if the update does not help?

If after all the manipulations the curtain still works incorrectly, consider the following options:

1. Reverse to previous MIUI: Download old firmware from Xiaomi. Install it via Recovery or Fastboot (see sections above).
2. Custom firmware installation (e.g. LineageOS or Pixel Experience): Requires an unlocked bootloader and TWRP installation. Before installing, check firmware stability reviews for the Redmi Note 7.
3. Reset to factory settings: Go to Settings → Additional → Restore and Reset → Reset. This method will delete all data, but often solves software failures.

If the problem is hardware (e.g., part of the sensor is not working), try connecting the phone to the PC and controlling the curtain via the Mi PC Suite or ADB. For example, a command to open the curtain via ADB:

adb shell am start -a android.intent.action.MAIN -n com.android.systemui/.SystemUIActivity
