Ok let's give some big good and bad news.
From the last few days i was working on a possible way to put a retail PS3 into debugger mode, i found a way to give this possibility and also some good surprises.
about the bad news (not too bad) for now it would only work on 3.55 (forget about up than 3.55) but i have maybe my idea for later and have some unstability that i still need to fix (don't expect a release for now but i try to release this fast as possible)
the other bad news, i work on this with a PSPGo (yes with a PSPGo, i can confirm that the PS3jig of BrandonW work on it), i use the PS3Jig source (thanks to BrandonW for giving the source of PS3jig) and made my own code to boot into debugger mode.. still need to work on it and try also to adapt in software mode (it's completely possible, need to patch the LV2kernel, it's also what i'm doing with the source of LV2patcher and some other stuff)
They have also a way to make a 4.0 CFW possible (not on the way what you think and not related to the HEN of Kakarotoks, well i think, this is not a epic fail of Sony just a way to bypass this problem by using some tools)
the problem for now, it's more for the people up to 3.60+ (it's complicate at this step) but maybe maybe (need to be confirmed that we can patch the update to do something special, need to talk to somebody for that)
i'm sorry if that take a little bit long but it would take less if some dev would help, also i see that the PS3 Community give some free insult to the users that want to help, doesn't make any sense, if you want to insult somebody. go to said that to Sony, seriously or go outside take some air, the PS3 is just a console, don't need that much importance
I'm sorry also that i'm not the best dev that you are waiting for but again, i try to do my best to give help
And for the people said, i try to give a wrong way, my name is not M
when i find something i don't hide it, i let you know
(it's just a joke to take to seriously)
