What is lost-or-stolen mode?

 When we send the ColorHug device to you, we give you the choice of postage methods, as we understand a lot of people don't want to pay £9 postage for an item that only costs £48. Using untracked postage means that packages can get lost during tracking, and due to the distance selling regulations of the UK, any lost packages have to be refunded by the seller to the buyer. 

 In order to deter unscrupulous buyers, any packages that are registered as lost or stolen will have the ColorHug devices added to a blacklist. This means that anybody trying to update the firmware on a device that is registered as lost or stolen will have the hardware disabled. Serial numbers will not be added to this list for any other reason.
