Update (Additional Tutorial): Software method for 5.05 only (5.05 hackable CUH-1000 and CUH-1100 ONLY!):
.We had some interesting developments on the
PlayStation 5's 4.03 firmware just recently, Now developer
@zecoxao has dropped news for the PS4 in the psx-place forums today with a new tutorial that i must say interesting for the PlayStation 4 (PS4) community, as
PS4 PHAT Models (CUH-1000 / 1100) now has the
ability for a CFW (in the southbridge emc that acts like a second syscon). Now, this is an advanced task and you can do some damage to your PS4 if you do not follow the instructions and even so there is always a risk when your messing with internal flash (EMC in this case) ,So this is a
USE AT YOUR OWN RISK release.You have been warned of the potentials. This works on firmware upto 9.03, also works on devkits / early testkits From
@zecoxao "This only grants permanence over the southbridge and syscon, but does not grant permanence over samu it's just over southbridge and syscon you can think of it as a second syscon" So in laymen terms this is not like your traditional PSP/PS3 CFW, but rather a firmware for the EMC chip not the actual PS4's firmware (don't confuse the two).,The CFW (EMC) will allow for various things like " making the console beep, change temperature limits, increase or decrease fan speed etc"
