phone number doesn't work
then the number must be random for everyone. when you type in the dup number for henry-- on the bottom of the case file will be another 11 digit code- type that in and you should get a security camera photo when you scroll down- that code on the ID is the phone code
Number i got for the phone was 886986375670 it sends you to find the hidden camera. Turns out each number is different for the phone.
Put this number into the DUP database
it will than show you a camera picture with camera Id, than put the ID into the phone
Updated OP with Part 3. Sorry for late update, but I only got to start doing the missions at 11:30pm tonight. And it's now 3:25AM. Took me awhile to figure out the first one, but I finally did. Hope the guide helps.
See you next week.
