Hi all, I have an AT&T Galaxy S3, running Android 4.1.1 right now. I am planning to root my device primarily to get the latest android version (at least the one released by Samsung for S3). What is the least that I need to do? I have read about the implications of rooting but I'm not sure whether just rooting my phone without installing a custom ROM will do any good towards getting the latest android version. Flashing a custom ROM sounds a bit risky and I am not up for it right away. Links to existing article on this particular topic will also be appreciated. Thanks.
