PS4 hack from CTurt is working only on older Firmwares < 1.76 or lower. So I found some infos how you can get a PS4 with this Firmware.
The first PlayStation 4 bundles who where shipped is what you are looking for, from TheGuardian:
Also PS3DevWiki has posted the old bundles who where shipped with Firmware < 1.76.
- PS4 Glacier white with Destiny Bundle
- Killzone Shadow Fall Launch Bundle (EAN: 0711719260783)
- Battlefield 4 Launch Bundle
- Knack launch Bundle
- “InFamous Second Son + Killzone Shadow Fall + Knack” Bundle
- NBA 2K14 Bundle
- FIFA 2K14 Bundle
- Dynasty Warriors 7 bundle
- Dynasty Warriors 8 bundle
- Assassin’s Creed IV: Black Flag Bundle
- Infamous: Second Son launch bundle
- Watch_Dogs bundle
- Destiny Bundle (black)
- DriveClub Bundle (Black)
- DriveClub Bundle (Glacier white)
- Call of Duty: Ghost Bundle
But there is no released hack or CFW for the PS4 at the moment... it is just for your information about how to get a PS4 if the time is up and we need one with Firmware < 1.76.
