I tried to access this website:http://myraroldan.com/wp/2012/03/cre...r-nook-tablet/
but my browser (Safari 5.1.7) issued a phishing warning for this site. I did not open the site so I don't know if the warning is justified or not. You might want to try http://cyanogenmodapps.com/54/instal...7-nook-tablet/
I followed the instructions and d/loaded files and took the SD card route and it worked perfectly on the first try.
Also, if you have access to a PC I would use it and win32diskimager-binary.zip (at https://launchpad.net/win32-image-writer/+download
) to write to the SD card rather than the Mac or Linux Terminal.
