Instructions

There is an unknown three-digit code (such as 4-7-3) that, when entered one digit at a time into #PASS, will unlock the link between debug and secret. Find the three-digit code and create a file in your host that contains the code as a sequence of three values, followed by the development kit's RDK ID.
