i had tried to use CM cable 5A, but failed detecting pins..
tried to use pin out from hf port, still no luck..
i also searched in this folder
Code:

c:\program files\infinity box\chinese miracle\pinout\
i couldn't find one matching this phone's pcb layout.
been searching forum, still didn't find one

then i tried this way:

hello!

please take a look how easy is examinate your phone for correct pinout.
as you can see- battery is attached (phone powered On or not- does not metter). One multimeter probe is on GND (metall shield)
with another you touch one by one all points.
when you see 2,7-2,9 volts- this is Tx/Rx
On my example i am touching correct data pin (voltage 2,7 volts)
i found 3 places w/ output 2.74v

as rx/tx, but pin finder still can't find it

hello!

try 1 and 2 again.
first time try 1 as tx, 2as rx
next time try 1 as rx, 2 as tx
both times your box ground pin 8 must be connected with grounded phone part
