Root How do i delete previous user?

[AlK]

I recently inherited a bunch of electronic items from a deceased relative.
Among the items was a Samsung Galaxy 10.1 tablet. I charged the battery,
and it has a lot of neat stuff on it. When I try to access the internet, it default
to a site in Texas, while I live in Florida. How do I delete the current site, and
log on to Comcast?. I even tried to reset to factory defaults, (3 times) with
no success. Any help would be greatly appreciated.
Thanks
