I've used the image you kindly provided CRE. It is stuck on the "Please Do NOT Turn Off Your Device. Installing New Software..."
There is a picture of a Nook in the center and a green check mark in the top right corner. How long should this take (I'm assuming it reboots itself after finishing)?
I found your post from the previous thread:
"When I was ready to go it took several times of pressing the power button (I probably pressed every combination possible out of desperation) before it came to life. It booted up and came to the "DO NOT TURN OFF YOUR DEVICE" (or similar text) screen and a red X was in the upper right corner. Where I'm used to seeing this message go away and the Nook prompting me to eject my card before turning the device off all that happened was it remained on the warning screen but the red X was replaced with a green check mark after a couple minutes. Being paranoid, I probably left it on that screen for 30+ minutes before I finally forced it off, took out the card, booted into CWM, restored my backup image and now I'm all set! (My serial number was uneffected despite all my clumsy efforts to kill this NT). I had 1.4.0 installed and this image was made using files from the 1.4.0 acclaim_update.zip."
Thanks to you, meghd00t, and all others involved!
