Dopod s 1 how to set the synchronization server is to synchronize with the computer, and there is no synchronization device. thank you

1. Is there something wrong with the data cable you are using? Try more changes, or there may be something wrong with your computer's USB interface. Go and check the USB behind the computer host.

2. Have you chosen the hard disk mode? That mode is that you can't synchronize your phone with a USB flash drive. You should choose ActiveSync mode, that is, the mode of synchronization between mobile phone and computer.

3. Check whether your Microsoft ActiveSync 4.5 is installed correctly. I don't know if you mean that you can synchronize before, but now you can't or never can.

4. Turn off the advanced network function of the mobile phone, which will affect the synchronization of the mobile phone.

5. Turn off all firewalls

6. Is there something wrong with ActiveSync on the mobile phone? If not, please return to the factory settings.

7. Check whether "Allow USB connection" is selected in ActiveSync on your computer.

I wish your question were more detailed. The right medicine is fundamental. Have you ever connected before? If not, please restore the factory settings. I hope my answer is helpful to you. good luck ...
