My nook simple touch has been bricked by a tool designed to wipe all partitions that I found on a deep google search.
I can still boot up into CWM and attempted to use the backup to restore my nook to previous conditions.
Its obviously a vain attempt at this point to try anything else as I was capable to mount my internal nook partitions onto my ancient laptop.
The nook's partitions show up as unallocated on gparted.
I fixed my problem by downloading a tool called noogie. You burn it onto the sdcard and on bootup you connect your working nook to a computer; preferably a Linux environment like Ubuntu and go to a program called Disks.
You create a disk image file saved to your preferable location. After the image is complete you safely disconnect the nook and boot up onto noogie on the bricked nook and flash the image with the dd command. Using gparted or disk will pinpoint the location necessary for the text command. I would not recommend using the burn image option on the disk program as it will launch errors.
After the image is complete use the dd command to burn the image to the bricked nook's location.
sudo dd if=/location/restore.img of=/dev/nook_location
