I bought a used FO4 but when i try to install it, it only reaches 30% and then it stops and says unable to read disc check for straches or if dirty. Clened it and everything, turned of PS4, safe option 5 and nothing. Am thinking it might be pirated but I checked the disc and it looks original and it boots up and starts downloading patch but when I try to install it fails. Is it the game? Or maybe my ps4 (half a year old and have 140 gb space)?

Where did you buy it from?

A friend of a friend sold it to me.
