I purchased a rooted nook from ebay. I was rooted with cm9 and cm7 and was unstable. I tried to access the stock software, but was unable to so I unrooted the nook (for the childrens read along access). However, when i unrooted (8 reboot method) i am not able to register. Barnes and noble wont deregister without the original shipping address, email addres, and last four digits of the credit card. I told the ebay member i purchased from and he said he called and had it deregisted, but 12 hours later, its still not working. when i called barnes and noble, they said the ebay members real name was not tied to the device at all. HELP! is there a way around this.
