Has anyone managed to generate the iso or payload using this source?

 

[cerci]

Im not technical but how does this developers help? Is there new information that can help them in the right direction for a JB?

 

[Waseem26live]

Big news PS5 user.
But I'm still have ps4.
All games working fine without haptic feedback.

I don’t want to be one of them that ask, but I feel I have to as some stuff a little confusing.

What highest PS5 firmware will this bd-jb work on? I see 5.60 was released making me wonder if 5.50 is vulnerable?

 

[FrogDR]

@Doyle444 It works on PS4 Firmware up to and including 9.03 and PS5 Firmware through version 4.51.

 

[PSGamer24]

I was able to dump sandbox on 5.50.
