Hi guys, I recently got a Nokia 3120 and a DKU-5 cable. Unfortunately, when I plug my cable to the phone, nothing is happening. I tried the same cable on another 3120 phone and it detected the data cable.

The store I got the phone from has since closed and I cannot find the owner. I am stuck with a phone that has a busted data pins.

Anyhow, anyone know what to check or to test which pins are working? Or any suggestions? I hate bringing it to a repair shop. Maybe I can try fixing it myself first.

Thanks in advance.
