[Nook Color Android Development] here.david:
READ EVERYTHING BEFORE STARTING...

IF you can ADB that is the easy way as it is a few sec, otherwise, it took me a few hours to get the NORMAL way to "just right" manually get back...hopefully my instructions are clearer...as it takes a few mins if followed correctly...

Make sure the battery is charged enough to make it through the procedure, or do this with the device plugged in. If power is lost while it's flashing the ROM, the device could be permanently disabled.

After gong back to 1.0 then to 1.0.1 then root...

============================================

* To update to 1.0.1 you must do a complete wipe.

Complete Wipe - You must do both of these to completely wipe clean your NOOKcolor.

1 Factory Reset > Wipes /data

2 8 Failed Boots > Wipes /system

* You must update to 1.0.1 to use AutoNooter-2.12.25

--------------------------------------------------------------

Downgrade to STOCK

-------------------------------------------------

Re-Image the NookColor to Stock 1.0

To do a factory reset on the NC you need to force your reboot counter to hit 8.

Power off the nook then push power on button and when the "n" appears interrupt the boot process by holding down the power button until it reboots, do this about eight times, OR if you have rooted it/have adb working you can do the following on your PC/Laptop terminal:

adb shell

echo -n -e "\x08\x00\x00\x00" > /rom/devconf/BootCnt

reboot

===============================================

upgrade to 1.0.1 - download the Nook Color upgrade

---------------------------------------------------------

From your computer, drag and drop the downloaded file onto the main directory of the NOOKcolor drive. Do NOT unzip the file. You should not create a new folder on the NOOKcolor drive or add the file to any other existing folder.

Eject or Safely Remove the NOOKcolor drive after the file transfer is complete.

Your NOOKcolor will automatically recognize the file after a few minutes or when it goes to sleep mode, and proceed to install the updates.

Please do not turn off your NOOKcolor during the installation process.

Once the installation is completed, your NOOKcolor will automatically restart and go to the Home screen.

On the bottom left status bar a green "n" will appear. Tap on it; the software has been successfully updated.

===================================

root - you said you had that info so I am not re-posting that...see my reply in that posting (auto-nooter-2.12.25.img) if you have issues...

Good Luck...

===========================================================

BTW if you want to stop OTA updates....not sure whom 1st posted this and all the other info,,,sorry for not being able to give them credit...they know who they are...

Stop OTA updates - MUST ROOT 1st

adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system

adb shell mv /etc/security/otacerts.zip /etc/security/otacerts.zip_DISABLED_OTA_UPDATES

too undo it you would do

adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system

adb shell mv /etc/security/otacerts.zip_DISABLED_OTA_UPDATES /etc/security/otacerts.zip

That would rename the old file back to normal
