@XxYuKux12345 has Tweeted recently he has developed his own PS4 CFW!Sadly, we don't have more info at the moment, and only badly translated info from forum users on other sites on what its all about.
It seems an Japanese scene developer has coded his own Custom Firmware for usage on Modded PS4 Console and is working now on plans on how to sell the package which seems to be both a special hardware mod along with his CFW that you load onto your PS4.
Well will follow this developing news story, and update everyone once we confirm more info on what this Tweet is all about.
