Generally speaking, any ODE device (not necessarily Cobra) can run your homebrew, you just have to make it running in a different form (selfs as game discs and not as npdrm self), This is possible because of the random fail discovery of F0F, so you can actually sign any homebrew with the 3.55(-) private keys.
But TBH, JuanNadie did mention that the 3k and 4k models have an exploitable bootldr.
Technically, it is also feasible to install cfw on those exploitable models, WITHOUT USING A HW .
But it's not an easy task, because you have to discover lv2+lv1 exploit on current ofw and then obtain your cellBE HW key.
With this, you can actually do whatever you wish to your console, decrypt & ecncrypt metldr and bootldr (you can actually change the boot order to the old revisions, as it works for cfw users today...and of course, a lot more).
