IDK why you think this but you do not need any form of bootloader exploit for an emunand and the switches exploit is not patched on any firmware as it can't be, it is however patched in later revisions of the hardware.
Now as for an emunand it would depend on how the PS4 actually runs and if the access granted by whatever exploit allows the system to be rebooted/load into a redirected NAND.
without samuhax i doubt its possible sadly.
