zecoxao over at ps3hax.net explains why we will never see native CFW (Custom FirmWare) for new PS3 consoles like CECH-30xx and 40xx (Super Slim). In short, for CFW to work the private keys are required to sign, and the only reason those were found for 3.55 (and older firmwares) is the mistake Sony did when implementing the ECDSA algorithm which was discovered by fail0verflow back in 2010, a mistake Sony presumably corrected in newer firmwares. He also explains how it is possible with existing keys to run homebrew on ODE devices like 3k3y and Cobra on these new PS3 consoles by setting self files to run as mounted 'fake' discs, because there are way less restrictions to run selfs from disc than in packages (pkg). The way forward for any 100% software solution, that is not relying on ODE hardware, seems to be game exploits, which is pretty much the current cat-and-mouse situation on PSP (or PSVita emulating PSP) with HEN (Homebrew ENabler).
