[Nook Touch Android Development] persichini:
Just thought i would mention that you can apply this hack using Root explorer.

Here are my instructions if you want to add them, feel free to edit or reword them as needed.

Copy Files attached to first post to your sd card

Backup Original Files

Open Root explorer
navigate to /System
then to /framework (Now you should be in /system/framework/)
Click the Mount R/W at the top of screen
Long Hold on android.policy.jar Select "Rename"
Rename file to android.policy.jar.bak Select "ok"
Long Hold on services.jar Select "Rename"
Rename file to services.jar.bak Select "ok"
Long Hold on framework.jar Select "Rename"
Rename file to framework.jar.bak Select "ok"
Then click the icon at the top of the list ".." for parent Folder
Navigate to /app (Now you should be in /system/app)
Click the Mount R/W at the top of screen
Long Hold on Settings.apk Select "Rename"
Rename file to Settings.apk.bak Select "ok"

Move files to correct Folders

Click the icon at the top of the list ".." for parent Folder
Then click the icon at the top of the list ".." for parent Folder
Navigate to /sdcard
Navigate to the folder on the sdcard where you copied the files from the first post.
Hit the menu button on the phone and Select "Multi-select" option
Then select each of the following files by clicking on them
android.policy.jar
services.jar
framework.jar

Do not select Setting.apk yet.

Once they are selected click the copy button at the bottom of the screen
Then click the icon at the top of the list ".." for parent Folder
do it as many times as needed till you are at the root of the file system
navigate to /System
then to /framework (Now you should be in /system/framework/)
The Folder should sill be R/W if not
Now Click Paste.
Then click the icon at the top of the list ".." for parent Folder
Then click the icon at the top of the list ".." for parent Folder
Navigate to /sdcard
Navigate to the folder on the sdcard where you copied the files from the first post.
Long Click on Setting.apk and select copy
Then click the icon at the top of the list ".." for parent Folder
do it as many times as needed till you are at the root of the file system
navigate to /System
then to /app (Now you should be in /system/app)
Now Click Paste.

change the permission

You should still be in the app folder so we will start with the settings app
Long click on Setting.apk
Select the Permissions option from the menu
Make sure that Owner only has Read, Write selected.
Make sure that Group only has Read selected.
Make sure that Others only has Read selected.
Then click the icon at the top of the list ".." for parent Folder
Navigate to to /framework (Now you should be in /system/framework/)
Long click on android.policy.jar
Select the Permissions option from the menu
Make sure that Owner only has Read, Write selected.
Make sure that Group only has Read selected.
Make sure that Others only has Read selected.

Repeat for
services.jar
framework.jar

delete dalvik-cache

Click the icon at the top of the list ".." for parent Folder
Then click the icon at the top of the list ".." for parent Folder
This should place you at the root of the File System
Navigate to /data
Then to /dalvik-cache (Now you should be in /data/dalvik-cache/)
Long click on [email]system@framework@services.jar@classes.dex[/email] select "Delete" from the menu
repeat for
[email]system@framework@android.policy.jar@classes.dex[/email]
[email]system@framework@framework.jar@classes.dex[/email]
[email]system@app@Settings.apk@classes.dex[/email]

delete packages.xml

Click the icon at the top of the list ".." for parent Folder
Navigate to /System (Now you should be in /data/system/)
Long Click on packages.xml Select "Rename" from menu
Rename the file to packages.xml.bak

(optional) due to packages.xml regeneration, it's possible (in my case it occurred) that now when you turn on the NST, the demo mode starts automatically; in any case, it's turned off as soon as you click any button, so it doesn't make any harm; but, if you want, you can simply delete the apk to get rid of it:

Click the icon at the top of the list ".." for parent Folder
Then click the icon at the top of the list ".." for parent Folder
Navigate to /System
Then to /app (Now you should be in /system/app)
Long click on DemoMode.apk Select "Rename" from menu
Rename the file to DemoMode.apk.xml.bak

Reboot your nook

this can be done by either long pressing the nook power button on the back
or
From the nook simple touch tools app
by click the reboot button on the main screen of the app
