It's very simple! Here is how to:
"This device is not a part of developer program" - please wait a little. It takes some time for Apple servers to recoginize your device after we have successfully registered it. If you are facing this issue after 24 hours from registration, please contact our Support Desk.
"Error 3002" - you have held Shift+"Update" instead of Shift+"Restore", please check instruction №6.
You can use it locally or via cloud signing services.
