Charizardite y

[preacher]

Can someplease please tell me where I can find the Charizardite Y ? I know its in LCCC , but which room do I need to access?

You need to use a Data Chip on one of the computers down there. I think that lets you access a second computer, which unlocks the way to the mega stone.

Ive been it on for the last two hours. I cant seem to figure out which computer this is

Try using flash. Goes lower left passage -> upper left passage -> lower right passage.

I think you can't get it until someone mentions a LCCC location in Calcenon. That's when I found the path so it might be locked before then.
