I'm not sure what software you're talking about, but the fastest way I can think of to get those two files is to post a thread on this and other forums requesting someone send you a copy (apk) of them. Then you can copy/paste them back into your app folder. However, you will have to root again to do that. Then you can unroot and try the update again. I'm not a root guru, so maybe someone else can offer a better suggestion.
