I bought a used rooted Nook Color for my sister. It appeared to work fine; however, when I plugged in the charger at home it triggered a boot loop. It just keeps going to the Cyanogen orange and black screen with 6 options. I choose the first to boot. Eventually it will finally boot, but it's obvious something's not right and I don't really want to give it to my sister this way. Any suggestions as to what to do? I'm not completely clueless when it comes to rooting, as I did it way back in the Eris days, but I didn't install any custom rom's or anything so I'm not a pro there. Thanks in advance for any help.
