问题
I have an old device, Lumia 800, it was unlocked about a year ago.
Today i restored factory setting on the device and tried to unlock it, but i'm always getting the 0x64.
I tried to:
reboot the phone,
reset its factory settings again,
try to register with turned on/off WiFi / 3G / Location
run with/without sim-card
turned off skype
Still nothing helps, any ideas?
PS: i can see a device in my Dashboard, but DevTool returns me 0x64 and phone is still locked.

May be you Should UnRegister Your Device from Previous Registration (Dev Center) and Again Try for Registrstion Again. (Keep checking that Your Device's TimeZone is set Properly,Your Device has Connnectivity to Internet)
