AngularJS UI router: Block view - angularjs

Question

Right now i am making an AngularJS+UI router install application. But i have a problem, the problem is, that i want to disable access to the views, associated with the install application. I want to do it in resolve in the state config.
But the problem is i need to get the data from a RESTful API, whether the application is installed or not. I tried making the function, but it loaded the state before the $http.get request was finished.
Here was my code for the resolve function:
(function() {
var app = angular.module('states', []);
app.run(['$rootScope', '$http', function($rootScope, $http) {
$rootScope.$on('$stateChangeStart', function() {
$http.get('/api/v1/getSetupStatus').success(function(res) {
$rootScope.setupdb = res.db_setup;
$rootScope.setupuser = res.user_setup;
});
});
}]);
app.config(['$stateProvider', '$urlRouterProvider', function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise("/404");
$stateProvider.state('db-install', {
url: "/install/db",
templateUrl: 'admin/js/partials/db-install.html',
controller: 'DBController',
resolve: {
data: function($q, $state, $timeout, $rootScope) {
var setupStatus = $rootScope.setupdb;
var deferred = $q.defer();
$timeout(function() {
if (setupStatus === true) {
$state.go('setup-done');
deferred.reject();
} else {
deferred.resolve();
}
});
return deferred.promise;
}
}
})
.state('user-registration', {
url: "/install/user-registration",
templateUrl: "admin/js/partials/user-registration.html",
controller: "RegisterController"
})
.state('setup-done', {
url: "/install/setup-done",
templateUrl: "admin/js/partials/setup-done.html"
})
.state('404', {
url: "/404",
templateUrl: "admin/js/partials/404.html"
});
}]);
})();
EDIT:
Here is what my ajax call returns:

Try this way:
$stateProvider.state('db-install', {
url: "/install/db",
templateUrl: 'admin/js/partials/db-install.html',
controller: 'DBController',
resolve: {
setupStatus: function($q, $state, $http) {
return $http.get('/api/v1/getSetupStatus').then(function(res) {
if (res.db_setup === true) {
$state.go('setup-done');
return $q.reject();
}
return res;
});
}
}
})
Then inject setupStatus in controller:
.state('setup-done', {
url: "/install/setup-done",
templateUrl: "admin/js/partials/setup-done.html",
controller: ['$scope', 'setupStatus', function ($scope, setupStatus) {
$scope.setupdb = setupStatus.db_setup;
$scope.setupuser = setupStatus.user_setup;
}]
})
