People will help when they can but you have to give them a chance. Even the old information can be useful. Did you follow up on the suggestion to find the file in /system/usr/keylayout and put a # in front of the keys to disable using a file manager like root explorer?
use titanium back up, then disable the search and browser, also if u have link2sd theres an option to disable the search and browser.
edit: please dont be so harsh if no one is answering questions, maybe the persons that know the answer is not online or available at the moment, as far as i know the people here are helpful.
