Answer 1

Use $state.go("main", {}, {notify:false}); for not notify to "$stateChangeStart"event.

  // NOT authenticated - wants any private stuff
  if(shouldLogin)
  {
    $state.go("main", {}, {notify:false});
    event.preventDefault();
    return;
  }


  // authenticated (previously) comming not to root main
  if(Auth.isLoggedIn) 
  {
    var shouldGoToMain = fromState.name === ""
                      && toState.name !== "main" ;

    if (shouldGoToMain)
    {
        $state.go("main", {}, {notify:false});
        event.preventDefault();
    } 
    return;
  }

I've created an example, playing with default pages and auth/unauth user. Similar issue could be seen here

Firstly this would be the listener:

app.run(function ($rootScope, $state, $location, Auth) {

    $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState) {

      var shouldLogin = toState.data !== undefined
                    && toState.data.requireLogin 
                    && !Auth.isLoggedIn ;

      // NOT authenticated - wants any private stuff
      if(shouldLogin)
      {
        $state.go('login');
        event.preventDefault();
        return;
      }


      // authenticated (previously) comming not to root main
      if(Auth.isLoggedIn) 
      {
        var shouldGoToMain = fromState.name === ""
                          && toState.name !== "main" ;

        if (shouldGoToMain)
        {
            $state.go('main');
            event.preventDefault();
        } 
        return;
      }

      // UNauthenticated (previously) comming not to root public 
      var shouldGoToPublic = fromState.name === ""
                        && toState.name !== "public"
                        && toState.name !== "login" ;

      if(shouldGoToPublic)
      {
          $state.go('public');console.log('p')
          event.preventDefault();
      } 

      // unmanaged
    });
});

What is happening?

• We check if user is logged in. If not, but requires access to not public stuff... we redirect to login
• user is logged in but not going directly to main... we transfer him
• user is not logged in, but not going to public ... we redirect
• else... let it be

And here are states:

  $stateProvider
    // available for anybody
    .state('public',{
        url : '/public',
        template : '<div>public</div>',
    })
    // just for authenticated
    .state('main',{
        url : '/main',
        template : '<div>main for authenticated</div>',
        data : {requireLogin : true },
    })
    // just for authenticated
    .state('other',{
        url : '/other',
        template : '<div>other for authenticated</div>',
        data : {requireLogin : true },
    })
    // the log-on screen
    .state('login',{
        url : '/login',
        templateUrl : 'tpl.login.html',
        controller : 'LoginCtrl',
    })
