You can't.
You can get all the Unknown, A-Z ! and ?
go into the smaller ruins and slove the puzzels on the wall. The floor will open and you will fall into the ruins of alph. You will then find unown in the ruins.
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 need Arceus to get Palkia in SoulSilver. Go to Ruins of Alph take Arceus with you then go inside all the doors and one of them will make The Sinniohn Champion appear then you will be able to chose between Giratina, Dialga and Plakia. They will all be a level one. This only works if you open the wall in the fake/tourist ruin in the Ruins of Alph.
you have to have the toys-r-us event arceus and go to the archeoligist in the ruins of alph. he will take you in the rooms and you will transport to the ruins of sinjoh.
In Platinum, Pearl and Diamond: Run around in the Solaceon Ruins In Heartgold and Soulsilver: Go to the ruins of alph, solve on of the puzzles in the rooms. They will open a trap door and you'll fall through it. When you run around in the ruins or alph a whole bunch of wild unown will appear
u have to get the pannels done then u go 2 the archeoligeats house and he will open them
Simple you just use cut on the door
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)
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.
you open the door and enter :P it is this simple :P
first you use escape rope to get moon stone ......... in the second one you use flash third you use water stone (you get it in the 7th gym on the bottom part in kanto) fourth you use ho oh in your front party
