I want to upgrade my s2 to lollipop but before that I want to backup my stock rom so that if in future I can reinstall it. Even tell me about best method of rooting I9100 and from where I can download lollipop for i9100. Currently I am running jellybean 4.1.2 version on my s2. You can also suggest me any other good ROM.
