Hay que decir que este método no elimina espacio en system, solo lo desinstala para el usuario 0. Y muy importante: si desinstalas alguna que luego quieres volver a instalar, te tocará Factory reset.
Como dije anteriormente, se podría crear un script donde añades los comandos que quieras y así se automatiza el proceso, muy útil para ahorrar tiempo tras una actualización.
