n3t_admin okay, I call the bluff here: so after the "feds" entered the (maybe incorrect) duress PIN, they were like: oh, it's wrong, have a nice day Sir! They didn't ask for a different PIN, they didn't retry it, they didn't ask why it was wrong? So many questions...
Due to operational security, I cannot share every detail about the device or what occurred, but the key fact remains: the duress PIN was entered, the secure wipe did not execute, and the data was subsequently accessible.
