Why won't my Riolu evolve?

Question

Recently I asked a question on how I can evolve my Riolu at Level 2 and most of the feedback said to raise its happiness to max and then level it up.

After a long, long while of IV Breeding, Ev Training through Super Training (because I didn't want Riolu to level up), plus tons of vitamins and long rides on my bicycle around the Battle Resort with Befriending Power Lvl 1 because I haven't unlocked 2 and 3, I go to Verdanturf Town to check the happiness of Riolu and she says that it can't love me any more than it already does.

So I think to myself that FINALLY got the perfect Riolu. Then, I feed it a Rare Candy and... Nothing. Then I think that Riolu needs to level up in battle so I go to Route 101 and fight a Level 2 Wurmple and Riolu levels up but still nothing.

What am I missing?

Answer 1

Like the others have mentioned you must follow these rules in order for it to work:

1. Have high friendship - I make mine hold a Soothe Bell and give it some berries that boost friendship, however these can also lower the stats.
2. Level Up during the day - This is between 10am and 6pm (Check your 3DS clock), however DO NOT change the time as that will stop all timed events for 24 hours.

If you follow those rules your Riolu shall evolve into Lucario. :)

Answer 2

If you have high enough friendship it should evolve when leveled up, but the part you are missing is that it needs to be day. Other than that, I don't know.
