C8 pro reset

Any help please I’ve just purchased a C8 pro and need to factory reset it, I’ve looked through the forum but can’t seem to find how to do this, can some one tell me how.. thanks

Why? If it's new, there may be another problem (e.g., with the fulfillment partner if it's not actually new), as you shouldn't have to do this.

Using the Diagnostic Tool, assuming you're all updated (scroll down on thia page if thhe link doesn't take you directly to the right section):

What exactly is the issue that you think you need to reset it?
