Hello,
I bought Playstation 4 Pro on the release day. I have swapped pro's hdd with my old PS4 hdd (it is 2TB - more space for my games). I have reinitialized the system and I thought that everything is OK. Sadly it is not. When I try to play any PS4 PRO enhanced game (for example Tomb Raider, Infamous First Light, Uncharted 4), my console freezes and error ce-34878-0 pops out. I have tried almost everything that I found on Internet and playstation forums / troubleshoot. I have swapped hdd back, reinitialised the system and redownload all updates / reinstalled all games. When old titles do work flawlessly enhanced ones just crash the system. I am playing on 1080p Sony's TV with disabled HDCP (to exclude this as reason). Polish support could not help me. Does anyone know how to fix it? Is my console broken?
