I got my phone used from the previous owner who didn't tell me they had rooted the phone. I know zilch about rooting a phone. So I would like to root it and find out as much information as i can and get help. Idk how the person rooted it before Odin program or what. Does it have to be "re-rooted" with the same program the previous owner used or can i choose a program i like? So lost any info would be very helpful. thanks.
