I have a Samsung Galaxy S2 Plus (4.2.2v) that I want to jailbreak. I heard another word for it which is "root". I don't know how to get started and how this works. Do I need a micro-sd for for this or just download some files on the internet on my phone? It would be great if I could get some help. Thx P.S If this isn't the right place to ask for guide then I would like to that you send my a link to the place.
