http://forums.qj.net...4068/page2.htmlIt's a locked thread I've just found.
I think it gives all the true story of ferrox exploit. It makes a lots of sense.
(1 person found exploit behind the "install other os" command, 2 other guys joined in order to make something useful. These 2 jobless guys contacted sony, and managed to obtain new jobs. 1st person promised to not give out exploit to protect their new jobs. However that person released a few videos to give hints about exploit.)
is probably one of these videos. Because at the very end of it there is a reference to the reason why the guys lost their job and thus why they got interested in getting new ones.
The consequence is you really need firmware<1.54 if you want to get rid of hypervisor on ps3 whatever is your final purpose (mine is to access RSX, and I will stop searching if ps3 linux is officially allowed to access it). It's propable firmware 1.54 is the result of the sending of the exploit details to Sony.
It's possible EE chipset is needed. But it's not 100% sure.
That closes the case 'ferrox exploit'. Definitely.
