Try it without the kernel.
Do the wipes (system, data, cache, dalvik), flash ROM, flash Gapps. Reboot into ROM. See if she boots up that way.
*Edit* You don't need to flash the JB Bootloader every time either. Once is sufficient, it won't go away until you change it.
Good call. Missed the part about the kernel.
