Sync Error, Unknown device - Cingular 3125

[baltika09]

I just got a Cingular 3125 off ebay and the phone works fine, I just got a data cable for it and attempted to sync it with my laptop, running Windows Vista Ultimate. It is being installed as an unknown device and neither WMDC nor Activesync is recognizing the phone. I've tried updating the driver, deleting and reinstalling the driver, resetting the phone, nothing has worked. My phone is a Cingular 3125 of the HTC Star Trek running ROM version 2.4.502.0. My OS is WIndows Vista Ultimate. has anyone had this problem or have a possible solution?? Thanks

Hi,

I'm facing the same issue. I guess, its a hardware related problem.

When I connect my SmartFlip, it shows charging icon at top, but in case of ActiveSync or WMDC - it says Not Connected. Even Windows detects it as Unknown device.

When I asked to service center, they said, its an issue with Hardware, but confused.
