Since gamecubecat has sold his unit and seems to be MIA from this site I'd like to continue his post if that's not against the rules? I have one of these units that I picked up recently and I've been playing with it. To continue what gamecubecat was discussing mine HAS the 1.76 firmware and when I try to run apps and such it doesn't ask me to update firmware it just gives an error code. I noticed online that all the videos of people showing these units are using the controller plugged in so I assumed the BT didn't work. It does indeed work and requires the same simple setup as the retail PS4. I was also curious about if these units would boot into safe mode in the same manner and they do. Just hold the power button in the same as the retail PS4 until you get that second beep. It displays all the same safe mode options as the retail PS4. The dev kit connects to my wifi just fine but the default PSN acct that's on it is the one form the previous owner and it won't auto login (the password is saved but I just get the loading circle) and I don't want to enter my own ID for obvious reasons lol. There is game data on it from a game that was available digitally for PS4 but doesn't seem to be on the PSN anymore. The game website and the developer website are both down and neither of their twitter pages have been active in over a year so I assume they are "belly up". It appears as if the game is on the console as it has a game tile and there are several screen shots and a video in the capture gallery of it in action however when I try to launch it from the game tile it just goes to the game splash screen and stays on it. At this point I have to press the reset button to restart the Dev kit. I wanted to dump all the game data to a USB drive so I plugged one in and when I did the copy it said that more than one USB drive was plugged in and to take them out and make sure one is connected. I only had one plugged in so I assumed there was an internal one or something inside the housing. I unplugged the one I put in and tried to copy it to USB again to see what it would say. It said there was no USB drive plugged in. So I plugged it back in to try again and it said there was more than one lol. I assume this is a random message it gives when prevented from copying to USB. I'm dying to try and reformat it with a retail firmware via USB in safe mode to see if it would become like a normal PS4 but I of course don't want to risk ruining it or taking away it's value. Anyway I believe this is all I can offer to add to what was already said. If anyone has any other info, please feel free to contribute! Thanks!
