The Azure Flute is a device which is used to encounter Arceus. Since Arceus sits atop a special platform over Spear Pillar, you cannot use the walk-through-walls cheat to access it. That cheat, however, does work for Shaymin.
But, you don't wish to use a cheat or attend a Nintendo event. Unfortunately, those are the only ways you can get the Azure Flute. Simply put, the Azure Flute is a Key Item (so it cannot be traded while it is attached o another Pokemon), it is not found by a Pokemon with the Pickup ability, it cannot be won or obtained in any other way than by hacking into the game or attending a Nintendo event (or, at least, linking up to one - perhaps by the WFC).
You may get Arceus (the point behind the existence of the Azure Flute) by other means than the Nintendo Event or a cheating device. It may be available for trade through the Global Trading Station available via Nintendo Wi-Fi) or a friend of yours may have one. If so, you can trade Arceus to your game without the fuss of a cheating device or Nintendo event. It is highly likely that the trader will want a high-leveled or rare Pokemon in return, so be sure you have one worthwhile to trade.
Really, though, the Azure Flute is a very exclusive item. You would be unable to find it without interaction of some sort with external devices - be it the Wonder Spot or an Action Replay.
no you cannot. unless you go to the special events Nintendo does.
Without trading, cheating, or Nintendo events, you can get Dialga, Uxie, Azelf, Mesprit, Heatran, Giratina, and Cresselia.
You can transfer it from an old Pokemon game (such as Pokemon fire red) or trade other people.
we cant do that."IT'S IMPOSSIBLE".you have to migrate it.or trade over Nintendo wfc
Currently, you can't get that Pokemon without cheating. There hasn't been a Nintendo event that allows it yet.
The only way to get a Deoxys without cheating is through a Nintendo event or trade. But the event is over.
to get Manaphy without cheating, you have to have Pokemon Ranger, beat a certain mission, and then somehow transfer the Manaphy egg to Diamond or Pearl.
yes with mystery gift
Only if you got the event.
this is impossible without cheating, even with cheating it may not be possible.
You have to mete the Pokemon lots of time, 1 time it will be shine.
definitely a Nintendo event
The Pokemon that can be caught without special events, trading, or cheating in Pokemon diamond are: Uxie Mesprit Azelf Dialga Giratina Heatran

No, the only way is to attend a Nintendo event.
