Do not work on my new hardware nook, with either 1.42 firmware OR 1.5 firmware.
BTW, this info:
is badly dated. All Eink nooks are currently rootable.
The above article will not work if your nook came with 1.5 from b&n. My understanding is not all nooks are rootable. 1.4.1 1.4.2 are rootable using that method but the bug allowing to use that method has been fixed in firmware 1.5. On top of that, the above method doesnt enable downgrading to 1.0.0 and installing unsigned updates. All it does is it starts adbd so that you can connect to your nook via adb and install apps this way.
