Lugia puzzle help (Level 135 Mirage tower)

[Cyphre]

So when you go with Saphira into the basement, get to the deadend and she says you gotta find a different way around. Obviously game implies i should get to this door in the other, crystal variant of this place but i'm having troubles getting to it. I get the general idea of what i need to do, but the ladder blocks seems to reset when i pass through certain doors, however i cant notice a pattern of when it happens.

 

Anyone got detailed directions or a video to help with that perchance?

Okay so for anyone like me who missed forest behind the trees, right before the door with the deadend i mentioned you just need to move the block to the bottom-left place you can. It was that simple.

What basement? I got the Ho-oh already but where is Saphira?????

[Cyphre]

Oh the first floor of Mirage Tower you can break the glass and that leads to a basement with Mimikyu and another door.

I remembered the Mimikyu but looks like they changed the entrance location so my game had the location explored but the entrance still not open. So I did manage to figure it out but thanks for the answer anyway.

They didnt, it's always the last glass you break on the ground floor.

My glass wasn't broken yet the underground area was already explored so I'm not sure what happened then.
