What it is

Maintenance Mode

The maintenance mode of the cell phone, the cell phone maintenance time into an empty user data system mode, to ensure the safety of cell phone data.

Also has child mode. Not useful if you are not in China.

Commands

adb shell pm uninstall --user 0 com.miui.maintenancemode

To put it back:

adb shell cmd package install-existing com.miui.maintenancemode

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
