Having this LG G Pad X 8.0 with the previous owner’s information on it can be problematic, but there is a way to remove it in order for you to enjoy it!
What you are experiencing is called FRP (Factory Reset Protection). I understand this has been reset. To make sure it has been reset properly, you can attempt an alternate factory reset from step 5 here: https://www.att.com/devicehowto/tutorial.html#!/interactive/id/interactive_1500011136?make=LG&model=LGV520
Please visit this link from LG for further details about how to bypass the FRP: http://www.lg.com/ca_en/support/product-help/CT20098088-20150103001317-others
I hope you are able to get this resolved. Have a great day!
