I followed the rooting instructions verbatim and I got the same issue a previous poster had.
When I get to "adb reboot bootloader" the backlight just turns off on the Nook and it ceases to respond. Holding power for 10 seconds gets a reboot.
I'm on OS X, i installed android-platform-tools.
When i hit 'adb devices' I get:
List of devices attached
5014610072485003 device
Should that have an exclamation mark to indicate I have drivers, is that what I'm to understand?
Looking elsewhere I see that there might be issues with getting a fastboot driver to work on OSX?
