Backup/Restore N2E OS X/LINUX

Rule one: Make a backup of your factory fresh Nook ROM.

Linux/Mac: Become root

Boot nook with noogie.img and connect to your computer via USB.

New link here

Linux:
use df -h to get your nook's /dev/sd? address.
typically something like: /dev/sdb

OS X:
use diskutil list to get your nook's memory address.
typically something like: /dev/disk3

Once you know the address, unmount the Nook.

Code:
Linux: umount /dev/sdb*
OS X: diskutil unmountdisk /dev/disk1
Make the backup

Code:
Linux: dd if=/dev/sdb  of=my_backup.img bs=1M
OS X: dd if=/dev/disk3  of=my_backup.img bs=1M
After it is finished, double check and make sure the backup img file is exactly 1958739968 bytes long.

dd can wipe your computer's hard drive, so be careful! Make sure your're plugging the correct drives into the command above.

Restoring your N2E to factory-fresh is a simple reversal of the commands above:

(boot with the noogie sd card first!)

Code:
Linux: dd if=my_backup.img  of=/dev/sdb  bs=1M
OS X: dd if=my_backup.img of=/dev/disk3 bs=1M
Substitute sdb or disk3 above with your Nook's actual address.

This wipes your N2E, restoring the specified image file.

Windows users, see the next post.

BACKUP/RESTORE N2E Win7

Grab a copy of Roadkil's free DiskImager for backup and restore. http://www.roadkil.net/program.php?ProgramID=12

and a copy of free MiniTool Partition Wizard at:
http://www.partitionwizard.com/

Boot nook with noogie.img : http://nookdevs.com/NookTouch_Rooting (the "Rooted Forever" screen) and connect to your computer via USB.

Use DiskImager to copy your Nook partition to a file, being sure to select "Physical Disk" in the drop down list.

If the process completes, you now have a backup.

To restore your backup:

(Boot Nook with the noogie sd)

Run Partition Wizard and delete all partitions on your Nook. Careful in disk selection here, wiping the wrong drive could be catastrophic! This is required, because DiskImager won't write to a partitioned drive.

Now run DiskImager and restore your backup to the Nook drive. When done, pull the noogie sd card from the Nook and reboot.

You should be fully restored now.

Then make a backup now. For most of the stuff that's being done, a factory restore will put you back to pure stock.

Already doing so - my current state is quite solid at the moment so it'll do as a known good restore point, if not as a "get me back to being a virgin" state.

Factory restore only seems to wipe /data, though - so anything you've done in system is not restored to stock.

I'm stuffed too. Is there any hope of a full factory install method that doesn't include making an image of the original ROM?

I don't see one on the horizon because the /rom/devconf data is individual to each N2E. Hopefully, I'm wrong.

As long as you're not currently in a horrible broken state, can't you force a factory refresh then backup?

I did that and was able to backup. I noticed my 1.82GB image was actually on Physical Disk 7, but other than that it went by the book.
