Yea, I saw that the other day... I don't mind discussing it in here as long as the Tweets aren't posted (many contain profanity, use Twitter for them). That said, my take on the situation is as follows:
When KaKaRoToKS first Tweeted about the new exploit he felt comfortable with his standing in the PS3 Dev circle, and then realizing he lacked information essential for an actual release turned to Mathieulh (who is in several PS3 Dev circles) for some assistance (meaning some more parroted details required for the hack).
In return for KaKaRoToKS getting PS3 sceners to 'like/respect Mathieulh' again, Mathieulh offered him a few bits (most of which is buried in the PS3 Wiki and is useless by itself: ps3devwiki.com/index.php?title=Talk:KaKaRoTo_Kind_of_%C2%B4Jailbr eak%C2%B4), but due to pressure on him from the real PS3 Devs (for example: adrahil, bushing, marcan, oopo, richdevx, sjeep, subdub, xorloser, etc some of whom moonlight working for both Sony and profiting off selling 'code' for dongles) who he actually gets the info from on being booted from their more elite circle he ended up ultimately telling KaKaRoToKS he offered what he could and bailed.
<eussNL> well, math shared a GUI with C++ code to cry about, an XML with keys (which are all on wiki) and told kakaroto to go look for omac himself (while there is no omac, nor pointing to where it might be - as if he did not even know for himself :P)
Ever even looked at the code I gave him ? I suggest you do, then compare it to tools and documentations about .self available elsewhere. You will notice they are basically worlds apart to each others. -Mathieulh
P.S. I wasn't aware this was the place for drama.
Of course it is always easy to oneself such as Kakaroto to claim to have had all that stuff already done (in private that is) AFTER receiving all the FULLY COMMENTED sources from me eh ? Oh ! And if I got the entire self format, crypto, compression, flags, calculated offsets etc etc reversed and done, and that I know that what's required is a hash, chances are I most likely got that too... (just saying).
Just a protip, don't focus on appldr you'll have to look at lv1 to figure what is going on, otherwise you won't be finding it, at least no easily. Best way, live debug lv1 while hvsc99 is used.
KaKaRoToKS was then upset and to save face Tweeted calling Mathiuelh out for 'not sharing' and 'making him waste his time' knowing that unless one of the more elite PS3 Devs spills all of the required details (usually done though Mathieulh as the mouthpiece, so it won't be tied back to them in case Sony comes knocking) the exploit may not come to fruition... at least from an end-user standpoint.
So where does this leave us from here? Basically in the same place as before... waiting for one of the elite PS3 Devs to pass the necessary details and/or files to someone (Mathieulh, KaKaRoToKS, fail0verflow, Gitbrew, etc) as the 'mouthpiece' to release them to the public under.
My guess is just like what happened with the PSJailBreak and PSDowngrade, this will happen when the elite PS3 Devs have squeezed as much cash as they can out of the dongles and reselling the code to cloners (which is what's currently going on based on recent e-mails we've received).
Here is to hoping someone leaks/passes along the missing exploit details soon, whether it be to KaKaRoToKS or whoever is going to be the designated person/group to share them with the scene!
