you need to use special hm moves and/or items to open the doors. the unown symbols corresponds to the letters of the alphabet, so it should be easy to figure it out.
every time you have to open the door, stand in front of the door and follow these instructions.
here is the list:
*first door: escape robe (item/use)
*second door: flash (hm move/use)
*third door: water stone (item/use)
*fourth door: ho-oh (in party/interact with the door)
Somehting to do with the writing on the purple blocks. But I'm working on it!
You can get natu at the ruins of alph in heart gold and soul silver
get to the south entrance and go to the middle of the1st floor and give your pokemon the move flash then press "a" at the purple stone
Read the unowns and find out what there saying for example: One wall says Ho-oh so have Ho-oh first in your party when checking the wall or the another says Light so use Flash.
To open the two locked "Trap Doors", you need to complete the puzzle given on the wall in front of each of them. It will give you a hint as to what each Pokèmon is, and it's not that hard, either.
You can't.
You have to get there in under 100 steps from entering
Allow you to find more Unown in the ruins.
