Ok guys, I did all this and I am rooted. Now there is a new update, so all I need to do is exclude system partition and Iam done? Like you said it.
So the question is should I do this using flash tool, or updating it using pc companion and then use towelroot?
And if I use flash tool should I delete davlick cache(I'm not sure if flashtool has that kind of option, since i haven't used it in a while) or something like that before flashing the new update. Sorry if you've repeated yourself but its 4 am and I dont feel like searching 40 pages :S
And P.S. Link where I can download latest version of 4.3?
