Exclamation Help with cables, no schematics question!!!

Hello masters, i have Infinity box just recently buyit.

Got a few problems because some cables are not with the set. And also, canīt be found here in South America.

So, the fact itīs that to solve this kind of problems i MUST learn how to make my own cables, for this and another boxes.

Iīve seen everywhere the schematics, like this ones in this post, bu t i canīt understand the info. Iīve got NO elechtronic knowledge and this could be a pain in the a** sometimes.

So, cable is not there ( c300 for pantech pg 3210 ) but iīvr got the USB one.

So, i cut it, looking it very carefully, and got MORE desconcert.

I made a few tryes:

- Try to Understand wich connector is ONE ( this cable got 24 pins, starting from where is ONE ? )

- Guessing wich ones are, make a couple of rj45 tests. In both cases, leds of RX and TX of the box really works hard, but never get phone connected.

USB cable got 24 pins i say: correct.
Got only 7 solded cables tru pins. And 2 "bridges" made with short cables from one side to another of the circuit. ???????

Wich one of those are RX And TX, how can i identify it?

Really, wich cables go to the rj45 connector? only 2: RX and TX? what happend with all others? Should i eliminate them?

Ey man, sorry about my bad english. At this point, better some photos to understand tahn more schematics, boys.

So, if you can help, i ve very happy and gratefull to you. Waiting.....

P.S.: this is the info about pinout of this particular cable:

=== DATA MODE ===

3: connect to phone pin 4
4: connect to phone pin 3
10: Phone Rx (RJ-45 pin-2)
11: Phone Tx (RJ-45 pin-3)

In this case i got NO IDEA what we are talking about.....
