The BADIRET exploit has been released for the PS4, this is a Kernel Exploit which gives full access to the PS4 hardware.
This exploit was designed to work on PS4 firmware version 1.76 originally, however it may work up to firmware 2.01 if a different entrypoint to run the exploit is released.
Team Fail0verflow who have a full Linux distro running on the PS4 decided to also release the missing pieces from their Linux booting on PS4 talk. This means in theory everything is now out there for the public to get Linux running on the PS4.
As the PS4 is capable of booting Linux, it is also capable of booting a patched Orbis OS, with security restrictions removed. That essentially means homebrew in the PS4's Orbis OS. The PS4 scene is in its infancy, however this is a big leap forward, especially as things are now out in the public. You only need to look at the 3DS scene to see how that progressed!
The Digiex team have invested in an exploitable PS4 on firmware 1.76 in the hopes we can bring you some high quality tutorials in the near future.
The ideal way to get yourself a PS4 on old firmware is to buy one of the old bundles, and to ensure it's new, not used. The exploitable firmware you need is is 1.76, so you need to obtain a PS4 on this firmware or lower. You can easily upgrade to 1.76, however it's not possible to downgrade to it.
The list of exploitable PS4 bundels are as follows:
Amazon UK and Amazon US still stock some of the above bundels which are new / factory sealed so will not have been updated. You could also get lucky on Ebay, however be aware consoles purchased on Ebay could well have been updated if not factory sealed.
