Removing XTR LCD Panel Lock

From CobaltFAQs

The XTR provides the ability to "lock" the LCD panel and prevent unauthorized access (to shutdown the server, change the IP, etc) by entering a Nintendo-like sequence of up-down-left-right key presses.

The "password" (numeric keycodes) are stored in /etc/cobalt/.fppasswd

The LCD panel "lock" is /etc/cobalt/.LCK..cobtpanel

Remove the two files and you will have access to the LCD functions again. You need shell access as root to do this (via SSH or a serial cable).

The script /usr/local/sbin/fppasswd.sh controls all the LCD panel password setting/clearing/etc on the XTR.

All the LCD menus/functions are controlled by scripts in /etc/lcd.d (this last part is true for all the Cobalt products).
