@ jentz,

Please make sure that:
  • Battery charged more than 50%
  • All the side programs, that may interfere with the phone, are closed
  • The phone cable will not be disconnected till the process is done
  • Connect phone to USB port placed on the back side of PC (motherboard's USB port).
  • Avoid using any kind of USB HUBS.
  • Phone has stock (factory) firmware version.
  • Ensure that the drivers are properly installed

After that run Direct Unlock operation according to this manual once again.

Best Regards
GSMServer team
