Use this script to debug ui-view (works with minified files too!) Just paste it on console and hit enter.

debug-ui-view.js

jQuery(function ($) {
    var view = $("[ui-view]").first();
    if (!view) return;

    var $rootScope = angular.element(view).injector().get('$rootScope');

    $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
        console.log('$stateChangeStart to ' + toState.name + '- fired when the transition begins. toState,toParams : \n', toState, toParams);
    });

    $rootScope.$on('$stateChangeError', function (event, toState, toParams, fromState, fromParams, error) {
        console.log('$stateChangeError - fired when an error occurs during transition.');
        console.log(arguments);
    });

    $rootScope.$on('$stateChangeSuccess', function (event, toState, toParams, fromState, fromParams) {
        console.log('$stateChangeSuccess to ' + toState.name + '- fired once the state transition is complete.');
    });

    $rootScope.$on('$viewContentLoaded', function (event) {
        console.log('$viewContentLoaded - fired after dom rendered', event);
    });

    $rootScope.$on('$stateNotFound', function (event, unfoundState, fromState, fromParams) {
        console.log('$stateNotFound ' + unfoundState.name + '  - fired when a state cannot be found by its name.');
        console.log(unfoundState, fromState, fromParams);
    });
});
