Note

At present, configuring email, Wi-Fi setup and browser configurations are all that are available to troubleshoot on the Blackberry 10.
 
One of the most important links is to "swipe" at the top of the screenshot (above the clock area). That will bring a menu containing the "Settings" location. For that location "Tap, hold and swipe down" on your Blackberry. Simply click for this demonstration.

Only the "swipe" area and the Browser icon are selectable in this screenshot.
