The first CPU is MT6225A and the second is MT6223AA .
I used MT : MT6205 , MT6217-MT6228 , MT6230 .


I also used CPU independent ( it found first CPU also ) .

Thanx !

hello!

I compared with all available ZTC pinouts: nothing similar in our database.
best way to find second pinout now is measure voltages on pins 4,5,6,9,10,11,12
battery must be charged and attached to phone.
pins with voltages 2,7-2,9 volts will be tx_b, rx_b
