There isn’t a CFW for PS4. But what we have is GoldHEN (which enables us to run decrypted games, also called fPKG’s) and various methods to run GoldHEN.

Up to firmware 9.00 (I believe) there is a browser exploit to run it, up to 11.00 you can also hack the console via PPP (pppwn) and up to 12.02 GoldHEN can be loaded with a BluRay you have burned before.

So you basically start the system and put it in a state where it accepts unsigned code. It’s very similar to PS3HEN. There’s also a method of hacking the console with some obscure Japanese games and one with a PS2 game. Some absolute madlads even made it possible to hack the PS4 with an LG Smart TV. 😆

The channel MODDED WARFARE always reports on those methods and makes tutorials, highly recommended.

And a PS4 BluRay exploit has just been released, so you can crack the whole thing by burning a BluRay (up to a certain software version).

Lots of legitimately obtained backup copies to play!
