Can you help me here, I wonder, please? I have been going a bit nuts and glad to find this thread. Basically my original N800 is a bit the worse for wear having been cheerfully abused by my 3 year old grandson (bless him) so I bought a second hand N800 in pristine condition to replace it. Navicore needs to be deactivated on the old handset and then re-activated on the new. I couldn’t understand why my deactivation request was met with “Licensing Error/An unknown error (0) has occurred”. Since it is clear that neither Navicore, Wayfinder nor Vodafone will help, how can I spoof the deactivation/reactivation process on the relevant devices? This is legitimate software that I purchased with a lifetime licence so I am not being shady in any way.
