Where to get the contents of the iOS 6 file system?

Question

iOS

Maybe someone saw the unpacked iOS 6 file system somewhere?
I would be very grateful for a link to this. Went through everything I saw.
If there is no such resource, maybe someone will help out.
You need files from the jailed device from two directories:

/System/Library/Frameworks/UIKit.framework/Keyboard-хх.plist

- need plists of keyboards. (хх — language code, e.g. ru, en, etc.)
/System/Library/TextInput/TextInput_xx.bundle/— we need bundles of keyboards of different languages ​​(хх — language code, e.g. ru, en, etc.)
I can, if necessary, somehow compensate for labor time -expenses.

But what prevents you from picking up the IPSW firmware?
