hi, man i found them but they are many:
GND,RX A,RXB,power,power,TX A,TX B,VBAT
so which TX and RX to take?

for Nckia 5700 10-Rx,12-Tx (in most cases),if not correct try 7-Rx,9-Tx.Use 1 or 18 as ground

GND-RX _A-TX_B-POWER A-POWER B-TX_A-RX_B-VBAT and i'll upload th pic,so which one to take or just go to pin 10 &pin 12 and the GND?

Rx_A, Tx_A corresponds to CPU1,Rx_B and Tx_B to CPU2,phones Rx attach to box Tx(pin3),phones Tx attach to box Rx(pin2),Gnd to box pins 7,8.
But if You have good working cable (18A) -better use cable and do not demage the phone with soldering iron .I have tested 4 different hardware versions of this phone and each version has pinout directly in the connector. Gnd You can use even SIM cards metallic cover or TF card metallic cover.

try and test!

you must take needed signals from box Rj45 connector.
box pinout you can find printed on box or in our FAQ section.

i wrote little tutorial how to build own cable step-by-step
