Load data SQLite in ionic bootstrap

I'm looking for solution for load data from sqlite in cordova bootstrap, for more specifically in $ionicPlatform.ready but until here I don't have a solution. See a piece of my code (I'm using ionic with $cordovaSQLite):

app.js file

...
app.run(function($DB, $log, params...){
    $ionicPlatform.ready(function() {
        ...
        $DB.init().then(function(res){ 
            // here I need load a user
            $rootScope.user = res;
            $log.debug('1 step = user loaded');
        });

        $rootScope.$on('$stateChangeStart', function(event, toState, toParams){
            $log.debug('2 step = use user loaded!');
            var _requireAuth = toState.data.requireAuth;
            if(_requireAuth && !$rootScope.user){
                event.preventDefault();
                $state.go('login');
            }
        });

    });
...

DB.js file

app.factory('$DB', function($q, $cordovaSQLite, params...){
    ...
    _self.init = function(){      

        var deferred = $q.defer();

        $cordovaSQLite.execute($ndDB.open(), "SELECT * FROM user LIMIT 1", [])
                .then(function(res){
                    if(res.rows.length > 0){
                        var _user = {
                            id: res.rows.item(0).id,
                            name: res.rows.item(0).name,
                            ...
                        };
                        deferred.resolve(_user);
                    }
                }, function(err){
                    deferred.reject(err);
                });
        return deferred.promise;
        ...
    };
    ...
});

config.js file

app.config(function($urlRouterProvider, params...){
    ...
    $urlRouterProvider.otherwise('/home');
    ...
});

The problem is, I need $rootScope.user before all, because I need authenticate and redirect, but always I go direct to home, because $rootScope.user is already late and $stateChangeStart no apply redir. If put it in $DB.init() callback, the behaviour is the same because default route is /home and stateChangeStart load after Db.init().

Now I'm using a bad method, in home I check $rootScope.user and redirect to /login, but it's so bad because first we see the transition between home and login.

If I use the localStorage, it works fine, but I really need to use the sqlite.

What the best approach for this? Thanks
