Again to sum this 20 page topic up. All you need to dump the lite-on 74xxx key is the following:
1> Running Windows XP.
2> Buy this CABLE:

4> A safety pin.
When you get your cable, cut the connector off that connects to the phone..Cut the outer black plastic about 5cm and cut the blue and green wires off. You don't need them. Only need the white one for this specific make and model from this seller.
Strip the wire and wrap it around the safety pin and you done. Install the driver, plug the cable in and dump away


Yeah it doesn't look fancy but it works. Once you got it working you can make it look pretty. Hope it helps
