Article Ordering by id in frontend

Hello,
would you help me please, how can I order (to show) latest Article in frontend first? (also order by id). Or where can I read about .. I think it is not difficult but somehow I cannot understand why the articles are displayed always wrong (random.. and so)
In standard joomla configuration for articles in articles manager it is no opportunity to show (order) article by id.. I do not really understand why.....
I found somewhere in forum a solution for this, that I need to change in /administrator/components/com_content/models/articles.php
from
// List state information.
parent::populateState('a.title', 'asc');
to
// List state information.
parent::populateState('a.id', 'desc');

But articles in the parent category are displayed all the same wrong. (Perhaps the conclusion of the Article takes place by turns each category and, thus, not the newest article could be on the list first.)
In subcategories latest articles was displayed first, also right

I install FC, but I cannot found some opportunity to display latest articles first in list. My changes I have removed.
I set in global config: in tab "Content Lists":
Primary Order -> contents ordering attribute
in tab "Backend Managers", in Items Manager Order -> Item Id, and then Items Manager Order Direction -> Reverse

In menu I have menu-links to category and sub-categories.
All are setted in "Blog Layout Options", in Article Order-> Article Manager Order, then "Use global". Not work
I tried with
parent::populateState('a.id', 'desc');
too, but the articles are not ordered by id.....

In categories, under "Parameters: Items List Creation", Items Ordering -> contens ordering attribute
Under "Custom field" -> please select, also no changes

Thank you

Hello,

OK, there is no such option to order by item id,
but of course it is possible to add

Just, if you do not modify the creation dates and you order by most recently added, then you will get the same effect ... as ordering by 'id' property of the FC items (= joomla articles)

Can you tell us the scenario you have in mind ?

Hello,
yes, so it works.
I have just some news on the Site and wish that latest news are displayed first.
Thanks
