It is tasted and also you can test it.

1 step is* we need to find GND from phone.

2 step is* we should power on phone (operation with dead phone:

phone must be 100% dead by software)and take multimater put it to voltage.

3 multimeter (-) line put it GND and with (+) line check each connectors

* and usually Tx= 1.8v or 2.8v and Rx=1.7v or 2.7v

(it will be change by processor but strongly 1.7v or 2.8v not 3v or 4v)

This way is too easy and you will save a more time.

12 pin. You must find (Infinity team give good Idea 1.2.3 punkts):

1) GND usually it has got 2 GND. (now we have got 10 pins)

2) We will uncheck USB + and USB- (VSS) just with checking by USB cable (now we have 8 pins)

3) By USB cable we also uncheck V bat+* ac adaptor + polarization (now we have 7 pins)

4) Now from this 7 pins you will find 1 or 3 not used pins (last operation we have 3 or 6 pins to find Rx Tx signals)

5) Now at last operation you should use good multimeter just to find Rx Tx with 1.7v-2.7v or 1.8v-2.8v

6) WHEN PHONE IS POWERD OFF TX AND GND WITH MULTIMETER MAKING BEEEEEP
