I just bought a rooted Nook Color from eBay so I did not personally root this device. I do know that it is not booting through the SD card. It is installed internally. I also know that I am running Android 2.3.3. It is CyanogenMod 7.0.2. (I have no idea what any of that means.) My problem is that the Market app inconsistently crashes. Sometimes the screen just freezes right after I open it. I have been holding the power button down for 20 seconds to reboot it. Let me know if there is another way. Other times I get the "force close" message when I try to access the market. I have been able to successfully download several apps. But sometimes I have to try 4 or 5 times before they install. I often get the message, "download unsuccessful, please try again." I want to send it back but I don't know how to remove all my google account information. I tried to erase it last night and my google account is still there. Obviously I can't send it back with my google account so I am stuck with this device. If I can't get it fixed, I will have to figure out how to unroot it.
