[Nook Color General] bt1980:
It got so bad that I went back to rooted 1.0.1... At the moment, I have been observing that the official Barnes and Noble OS v1.0.1 rooted is the most stable and functional configuration for the Nook Color.

I have been working on a how-to, to make it easier for people to get back from NookieFroyo on EMMC... to a rooted 1.0.1. (this should also work from a Nook Color that isn't booting at all from internal memory). Many thanks to the original contributors (attributed below). I am merely trying to itemize all the steps.

1) Download WinImage (win32diskimager won't work for the following steps...). You can get WinImage here:

http://www.winimage.com/

2) Download this Image and burn it to the SD card with WinImage (using the "Disk" -> "Restore Virtual Hard Disk Image on Physical Drive")... if you cannot see the file when you browse for it... it may be the file extension, change the browse window to look for "Files of Type" = All Files.

Image download link (it may be zipped or compressed, decompress first) - for some reason only WinImage will work for this task:

Got that from brianf21 here - http://xdaforums.com/showthread.php?t=938200

3) Power off Nook, put SD card in. Power on Nook. It should boot into Clockwork Recovery screen (text menu)

4) Under mounts and store, format /data and format /system (volume buttons move up and down, N button selects, power button escapes)

5) Escape to main menu, go to "Install Zip from SD card" and install the 1.0.1 file (do not install the Froyo file). Wait until it finishes, do not interrupt this process.

6) Power off the Nook, remove the SD card. Power on Nook and register it online. As soon as you are done registration and see the Nook desktop, power off the Nook (do not let it run any updates, if it downloads the Elephant book, it's ok).

7) Download and burn this image to SD card (you can use either WinImage or win32diskimager for this):

The remaining instructions are here (But I will itemize them more briefly for you below...)

Much thanks to TheCubed for this thread - http://xdaforums.com/showthread.php?t=922870

9) Insert the SD card (with rootpack written to it) and power on Nook. It will boot into Clockwork Recovery menu again. This time you do NOT need to format anything.

10) Go to "Install from ZIP" and go into the required folder, install "root.zip"

11) Install "googleapps.zip"

12) Install "block-1.1.zip"

13) Power off Nook. Remove SD card. Power on Nook.

Once your device reboots, you will be presented with a setup wizard. (Below instructions from GabrialDestruir’s AutoNooter post on XDA)

1. Upon boot unlock your screen.

If it asks you to select a default application, put a checkmark in the box, and select SoftKeys as the default application.

2. At the Android Welcome Screen skip Sign In.

3. Enable Location Services when given the option.

4. Connect to Wifi and launch Youtube from "Extras".

5. Click the Menu button (The one RIGHT of the Up Arrow).

6. Select "My Channel" and Login using your Gmail Account. (YOU MUST USE YOUR FULL GMAIL ADDRESS!)

7. Exit Youtube and Launch Gmail from "Extras".

8. Sync your Gmail Account and Exit. (If it fails to sync that is fine.)

9. Open up Market and Accept Terms and Service.

10. Insert your SD card

11. Go to Settings > Device Info > SD Card > Unmount SD Card

12. Format SD Card

13. Install Dolphin Browser HD from market (and make it your default Browser)

When you install apps, they will appear under "Extras"

If you don't like the Barnes and Noble home-screen and want a different Launcher:

1) search the Market for ADW.Launcher and install it

2) Go to Extras -> SoftKeys and after you press it, there should be a bar at the bottom that has tools (second from the right). Select that

3) Virtual Home button > Normal Press > ADW Launcher

4) Virtual Home button > Long Press > Home

6) Back

Now any time you press the N button once, it will call up the "back", "home", "menu", "search", "softkeys prefs", "close softkeys" buttons.

Press the N button twice quickly, and it will bring you to ADW Launcher (a configurable desktop, with an application drawer button at the bottom, that works like most android devices)

You can still access the B&N Launcher by pressing the N to bring up softkeys, and then long-pressing the virtual home button.

I have discovered Kobo reader isn't downloading my books; but I tested Kindle works and Youtube works in the browser for me for sure. According to the documentation the YouTube app works for some people and not others. I will work on trying to figure out what the X-factors are on that.

Also, this still uses the older market; but I don't mind. At least it downloads, and seems to see more applications.
