Hi. I'm trying to fix a nephew's bricked Nook Color.
1. The device shows no obvious signs of damage.
2. I don't know what my nephew was last doing with the device before it bricked.
3. I have rooted phones and tablets of various manufacturers since Froyo. Not a nube.
4. I have used SDFormatter & Win32DiskImager to prep various sized and classed SD cards, but the Nook never reads from the Card.
5. The device will successfully factory reset, but that doesn't fix the boot issue.
6. LeapinLar seems to have the best tutorials. I just need to find a way in to restore what I believe to be a corrupted factory ROM. I'm hoping there is not an actual SD Card hardware issue.
7. Here are just some of the tutorials I have followed with no success:
