Looks like it was a false alarm and it was a bad card/adapter. I tried a different one and was able to boot to it just fine, HOWEVER--there have been changes to the new/refurbished Nook Colors. It looks like the internal partitions have been changed, so I can't get CM7 to install to the EMMC, but I can get root with no problem. I am having an issue with the market not recognizing very many apps for it, but I'm sure there is a simple workaround for that.I don't have my NC with me (at work right now) to verify the S/N, but I was able to root my previous NC (very seasoned with rooting many other android devices) with no problems. I'm beginning to think that I may have a "faulty" one, but I don't know how I can get it swapped again within the warranty. I did notice ONE dead pixel, but I doubt they'll swap it out for that! This thing is virtually useless to me without being able to root it!!!
