so you mean the core that can be downloaded from navifirm are the same with those core from the different cfw core? are they exactly the same?
I wrote REPARTITIONED cores. The core from navifirm isn't repartitioned. It contains rom,rofs1 & uboot all. Whereas the repartitioned core doesn't contain the rofs1.
U can use the same core, u used to flash with blaze, distro or SFR, to flash with this CFW. But u can't use the core from navifirm.
For more detailed explanation see my "ultimate tutorial to create ur own CFW" thread
