I used the one from:

I also had some problems at first, and I used this site to restore everything to the 1.0.1 nook state:

The link to the recovery img was dead, but I found it by googling. I've uploaded a copy.
Lastly, before I did the rooting, I updated the Nook with version 1.1.2 (don't use anything later because I read that Nook's later updates make it difficult to root).
If I can help further, please let me know.
