Issues with dev phone unlock. Constantly getting 0x64 error
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. 回答1: May be you Should UnRegister
