need help

I install Android with ammyt post, but I jumped the third update

(Update3: On-screen keyboard (size)
http://downloads.nitdroid.com/e-yes/LatinIME.apk

because it is a zipped file (LatinIME) I switched it to N900, and when I write in the terminal


Code:
root
mount / home / and
cd / home / user / MyDocs
LatinIME.apk cp / and / system / app /

............ not found, my file is not apk. just zip folder.

help?

and at the end, when I choose to start with boot nitdroid 2 on the keyboard, start the process, and ham to a part where we throw error
E: videop: xcb connct failed
E: videop: xcb connct failed

anyone hellp???
