I have bought 3006b ps3 since 2011 im still hoping someday it will support CFW, will we be able to do it if Sony finally announce the last update for the console ?! Thanks for the great team ever!
BTW @zecoxao said that he was working on a hard mod for these consoles, so via that method when CFW comes to current non-CFW consoles, then the current CFW(s) will work or will they need update to work.
Also i think then maybe some devs will return to the scene (i wish the rebug team at with the lite edition Fw)
ECDSA is the issue. Sony didn't use it properly 3.55 and below. In fact when properly implemented it has never been hacked with modern machines. It was exploited some years back using a microphone and tape recorder but that was over 20 years ago and long since fixed. Check the security tab.
