hello!

first of all lets clear if this is MT62xx MCU based phone.
For doing this without disassembling phone just type on phone keyboard *#0044# and then push green (send) button.
if you will see "language set: english"- it is mt62xx

hello!

first of all pinout mentioned in the beggining of tread is USB pinout for spreatrum phone.
second: I have only found pinouts for CECT T688 with 18pin connector and 2x5 connector.
this means that you have to find pinout yourself.
this is easy procuedure, please follow it:

1. make sure that phone battery is charged enought 3,7volts or more
2. set multimeter to voltage measuring.
3. set one multimeter probe to sone 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


here is little example that this can be done easyly:

Once you find 2 pins (tx, rx) with needed voltages please reffer to this tutorial:
