1.make sure your using a good SD card. sandisk 8gb class and up would be best
2. make sure you grab the 8gb nook cm7 image.
3. preferably use a component based card reader. by that i mean one other then a laptops.. the laptop ones tend to be picky and lots of people in the nook color days had issues and most were resolved by using a computer one over a laptop one
4. with the nook OFF plug the usb cable into the nook then into the usb port on a computer
check out stickies too
I wish you were correct but - in this case - you are not.
Your advice is probably appropriate for those who cannot get an SDCard to boot properly. However, the O.P. has a bricked device and his original post is most descriptive. His NT8 will not boot to the INTERNAL EMMC. (I have the same problem.)
There are several of us here on XDA who are not novices with this issue. The O.P. has listed the various steps that he has followed and they are much more involved than a simple SDCard format issue.
BTW, most formatting issues are when users are attempting to format with Windows. I use Linux exclusively and I can ALWAYS build a boot SDCard without issues.
Also in the same boot as the O.P.
