Para desinstalar múltiples apps instaladas en el móvil Xiami Mi 5 he seguido estos pasos:
1) Entramos en Configuracion/Acerca de
Hacemos clic 7 veces en VersionMIUI
2) Entramos en Configuracion/Sistema y Dispositivo/Ajustes adicionales/
Entramos en Opciones de desarrollador
Activamos 'Opciones de desarrollador'
Activamos 'Depuración USB'
Activamos 'Instalar via USB'
Activamos 'Depuración USB (Ajustes seguridad)'
3) Conectamos ahora el movil al PC por USB y en el móvil nos mostrará una pantalla en la que se solicita autorización para que el PC depure mostrando cierta clave RSA del PC. Aceptamos
4) Abrimos una terminal en el PC y editamos el fichero:
sudo gedit /etc/udev/rules.d/51-android.rules
5) Añadimos la línea siguiente, en mi caso 2727 es el ID de XIAOMI sacado de: https://android.googlesource.com/platform/system/core/+/android-4.4.2_r1/adb/usb_vendors.c:
SUBSYSTEM=="usb", ATTR{idVendor}=="2717", MODE="0666", GROUP="plugdev"
6) Guardamos el fichero
7) Ajustamos los permisos del fichero
chmod a+r /etc/udev/rules.d/51-android.rules
8) Lanzamos el comando 'adb devices' y debe sacar el móvil enganchado
$ adb devices
List of devices attached
024a89570005 device
9) Lanzamos el comando 'adb shell' y accedemos al prompt del SO del móvil
$ adb shell
vince:/ $
10) Sacamos la lista de apk de 'com.miui' y de 'com.xiaomi' que vienen preinstalados y precisan de 'demasiados permisos'
