Let me push this a little further...what would happen if I put a file in the original files place (same name) with just some text in it? If I accidentally hit "update" would it just error out, or would it check signature file, hash or something else, see that it was not the correct file, DL the correct file and then proceed to upgrade me to 4.4?
