I wanted to put up a bit of information on Barnes & Noble (B&N) Nook Color (NC) and rooting them. I have a few links to xda site where all the info comes from. Link to XDA
The Nook Color makes a great e-reader/Android Tablet when rooted.
There are a number of ways to root, I will mention a few. Keep in mind, this (well internal rooting) will likely void your warranty)
I am including a link to OverClocking (OC) the kernel also (The latest CM7 has this) it helps a good bit.
NOTE: I have never seen or heard of a "bricked" Nook Color, I have a link to how to restore them to the Stock OS below, but use these at your own risk.
ClubNOOK has a lot of good information and is a great place for help.
ClubNOOK has a great post with links to video's for rooting here
They also have a good thread on what rooting is here
There are a few ways to root the NC:
1) Use an uSD card to boot from (Not really rooting it as this does nothing to the NC OS)
This allows you to get a feel of how it works as a Tablet, it does not work as fast as when you root the eMMC (Internal Memory).
2) Use ManualNooter link below or just click on it here) to modify the Stock B&N OS. This has the advantage of using your NC
in a way that it will be able to run as a stock NC or as a rooted NC. You can install the Nook Home app and anytime you want the stock look and feel just run that app. I like this best because I have apx 360 Books, and I like to have BookShelves. When you root with CM7 or Honeycomb, you have to run the B&N Nook app, and it does not have BookShevles.
You have access to both the full Android Market, and The B&N App store this way. When you replace the B&N OS with CM7 or Honeycomb, you will not be able to get to the B&N App store.
3) Install CM7 or Honeycomb on the eMMC (internal Memory) and replace the B&N Stock OS. I like the look and feel of this the best, BUT I want bookshelves, so I use ManualNooter. This is REALLY sweet though, and really shows how well the NC is at being a Android Tablet. It runs faster/snappier than a ManualNootered NC IMHO.
CM7 (modified) and Honeycomb on a uSD Card Dual Booting to uSD (Actually triple booting when the Stock OS in counted)
CM7 Nightlies on eMMC replacing the B&N OS (Nightlies are the latest and greatest updates to Cyanogenmod 7)
Note: You do not need uboot with the latest CM7
How to restore Nook Color to Stock B&N OS You will need to make a CWR uSD first see below
