Hey bros! The hack is real, and it is not a real hack, but a real bypass, they are using a very simple and old technique from the MSX age, just simple rewrite eeprom, the quite and simple way to say GO. They arent decrypt or crypt anything. When sony tried to safe secure the PS4 they forgot to hardlock inside the CPU/APU the real hashcode for the bios, this is intent to not allow bios to be exchanged or rewrite, so, as they failure to do it, what the Hackers are doing is just simple running the real software inside one console, you can do it as psn/accounts, so the PS4 add $$$ game info inside the rom! So, they only need to stuff original games and matches run bios roms, so, the ROM/GAME will match and so will execute in the console. Remember that ROM can run a FOREVER SOFTWARE INSTALLED ON IT, so, all the games are REAL ORIGINAL and the PS4 arent hacked at all. The Hack is a bypass of ASM code for follow ROM/BIOS reading using a PI, YES SIMPLE AS BRAZILIAN WAY.
But all further games will depend on matches or DUMPS of BIOS/GAME, REMEMBER PS4 GAMES HAVE IT OWN HASH CODE! So, you cant decrypt it like in the PS3 default key, each game has it own key and it must match yo your BIOS coded hash, so, PS4-GAME tied forever! This only doesnt happen in a CD environment, where the hash authenticate the drive and return to PS$$$ that authenticate the BIOS and return with authenticate game, so, it is impossible to use a BYPASS in CD/SATA as no key extraction is possible in a 4 way schema.
