hello!

are you sure about number of pins?
also, is this phone is based on MT62xx MCU?

tip: you can check this by typing *#0044# and pressing green (send) button.
if you will see "language set: english"- you can be sure, that this phone is supported by Infintiy software

hello!

here only voltage measuring mthod will help:

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

when you find pinout make phone complete format, it will reset user code to default value
