Nokia E7 Charging / Usb pinout Emergency quick reply please

I have a Nokia E7, have replaced the charge / usb port, now it does not respond to the charger, I have checked the pin out from the brill diagram on here but mine is in reverse of what it says, ie pin 5 is ground on mine, not pin 1 as in the diagram....

When I plug charger in, it just reads as dead short, using bog standard usb charger with red light on, the light goes out when plugged in, using an lg cable, is the Nokia cable different..
