Previous owner isnt around and I bought this phone off them today. They removed their icloud and told me they erased everything but then when I got home its unlocked until I try to reset it. It asks for a passcode that i dont know and previous owner wont respond.
if you mean passcode then If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support
if you mean activation lock then Turn off Activation Lock - Apple Support
if it's activation lock then it's a lock on apples servers more than a lock on the phone itself and it's a theft protection
ISSUES WITH PASSCODE.
