Barnes and Noble has likely introduced a new hardware revision which bricks your unit if you install their official 1.0.0 Firmware (A step needed to root). As of right now, Nooks with serial #s starting with 1003 (running firmware 1.4.1) cannot be rooted, and should NOT be attempted. See New_Hardware_Revision for more details
