nook pin lock

you might want to secure your nook, if you have personal data on it. you can set a screen lock with a 4-digit pin. enter the following command in terminal or adb.

$ am start -n com.android.settings/.ChooseLockPin

you can change your pin the same way.

but removing the pin is a bit tricky, and needs a bit more hardcore hacking. this pin is stored in /data/data/com.android.providers.settings/databases/settings.db. use sqlite3 to remove the entry.

$ sqlite3 settings.db
delete from system where name like 'lock%';
