Cant connect to google services on samsung galaxy tab 3

[AC Question]

I accidentally updated while rooted, and now i cant connect to google servcies because "Cannot establish a connection" or whatever, is there a way i can delete everything on the hard drive and reinstall the OS fresh? When i factory reset the root app stays there. Please help!
