Cause it seems most guys are not interested in. For sure it's not a every one can do it task but a few of the devs in ps3 scene should be able to do that. We try our best to deliver a free version for every one.
Somebody said the SDK it's useless.. actually no... the SDK can reboot your PS3 into different mode (release/debugger/system software) and allow you to configure your system boot and what you want to patch, etc...
TB2/Cobra follow exactly what's going on in the SDK... you can reset/patch lv1-lv2...
TB2/Cobra use a LV1 wrapper like i said that allow to acces in kernel mode-> lv2/lv2kernel
Everythings you see is Syscall/patch on the fly (represented by subroutine and loc)
I'm gonna repeat but you can port the stuff from TB2/Cobra -> CFW but apparently no one was think about doing that... but the source of lv2 patcher v9 can help you (thanks to kmeaw) difficult to find, the good think about the lv2 patcher, it give you the possibility to make patch and payload that can load under lv2 patcher -> to patch your lv2
All the stuff about Cobra/TB2 is related to LV2kernel (the most important is that, the LV2Kernel that give you most of the possibility) -> that allow to give also a strong access to the Cell execution in rw mode
I never talk about 0A -> represent a error, i was talking all the times about A0, this is completely different
I still working on it because apparently no one want to help, anyway let's continue, sorry i do my best dude
