Solution

You can not hide bottom bar in NOOK HD devices.

Documentation given at NOOK Developers site says

NOOK HD and NOOK HD+ do not support true full screen mode. The bottom system bar always displays. Therefore, the NOOK "n" key is the home button and not the back key since the system bar contains a back key that always displays.
