How To Find Rx .tx Signles .
1. find Gnd pin (it's required step, you can't continue until you will know Gnd pin location)
2. find Charge pins (it's optional step, just to save your time during future research)
3. find +Battery pins (it's optional step, just to save your time during future research)
4. connect cable Gnd to phone Gnd
5. try to connect cable Rx/Tx wires to all phone contacts one by one (except Gnd, Charge, +Battery pins) and try to read flash from phone
6. if flash read procedure can start this means that pinout found Ok and you can make other operations
--------------------------------------------------------------------------
HOW TO FIND RX .TX SIGNLES .

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.

For example!
You have got new brand China miracle phone with USB cable. It has got
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
(DIOD TEST OPERATION), WHEN PHONE POWERED ON IT WILL SHOW LIKE DIOD
RESISTANS 600-700 OHM BETWIN TX AND GND.

hello!

1. set multimeter to voltage measuring.
2. check bettery voltage, it should be more than 3,7volts
3. set one multimeter probe to some grounded phone part
(if you cant find grounded part outside phone- you need to take out small thin wire from negative battery terminal)
4. with second probe touch one by one all phone pins (phone battery attached)
(to get better result i would advice to set needle on the end of second probe)

memorise pins with voltage between 2,7-2,9volts.
those are tx/rx
