I have the Famous "bsy" trouble with my 1 TB Seagate HDD and has purchased 2 no Nokia CA-42 cable for fixing it. Unfortunately, both of them have 4 wires namely red, green, blue and yellow. I cannot make out which one TX, RX and ground. ( i know abt them when there are 5 wires as it has been displayed in most websites).
It has a blue sealed usb end. Anyone can tell me confidently the RX tx and ground wires.
Reply most welcome

Ignore the colours. Instead follow the pinouts of the Pop port connector:
http://pinouts.ru/CellularPhones-Nokia/ ... nout.shtmlPins 6 and 7 are the Rx / Tx pins.
Pins 8 and 2 are grounds.
The remaining wire will probably be connected to pin 4 or 5.
Let us know what you find. A battery may not be needed if pin 5 is present.

Thank You, Fzabkar
I was talking about the wire when the pop-out port is trucated.
if you like i can upload picture of the wire.

The colours are meaningless. If the Pop-port is missing, then it will be a matter of trial-and-error.
You may at least be able to determine which wire is ground by measuring its resistance to USB ground.
http://pinouts.ru/Slots/USB_pinout.shtmlCan you see the USB-RS232 bridge IC in either cable using Microsoft's UVCView utility?
