deinstitutionalize or factory restore

Thats very interesting. I did not realize they made a special firmware for prisons. If it won’t accept a normal firmware file from this forum, reflashing it would be very difficult. It is possible to short out the memory and then reflash it from a linux machine, but often this destroys the player so I do not recommend trying unless you are going to throw it out anyway. Can you post the firmware version that is already on the player?
