Hello Android Community, I have a Nook Tablet which someone rooted and tried to install Android program on. I don't know what they did but it is stuck on a "Welcome to Nook Tablet" black screen saying "Touch the android to begin." I keep clicking green android on it but nothing happens. I tried to return it to factory settings but after the initial registration with barnes and noble and credit card information, I keep getting this same screen again. My question is: What do I do to get my tablet working again with the android market and everything? Please help me! Thank you so much in advance.
