Hello,

Please, explain what cable you have used and what you have tried to do more detailed.

Also download latest PinFinder manual: http://www.infinity-box.biz/download..._PinFinder.pdf
Please, see page 18: Automatic pinout detection: Troubleshooting

Cable was L18A (Is this correct ???)
And I was trying to repair "Restarting with Sim"
I was fixing it ok with soldering on PCB, but now, not working with auto pin finder.

Also "Find It" procedure fails

hello!

can not tell you if cable is coorect for your phone.
you must count pins and choose between 18a and 18b
check which one is fit there.

have you succesfuly used pinout finder before or this is your first phone?

can you power On phone for power lines?
This is common mistake when users use Btemp battery contact and connect there Red wire.
phone is not powerable On, pinout also can not be found under this conditions.

@dannyogolo
this phone don't have rx tx at connector.

its have under lcd.
remove lcd and there is 2 point at right side not marked as rx tx but they are rx and tx ..
be side of 18pin connector.
upper one is tx
down one is rx

thank you mr. cbz_4383 for confirming my words.

sometimes even phones with very big system connector doesent have tx/rx pins in it.
then we must solder wires to PCB

Thanks man
It works fine, easier than the way i was using b4.
But I know it has rx and tx on connector: we were soldering from inside b4 u finely "interupted"

hello!

some uniboxes have very small output voltage on pin1.
Also 0,7 volts is dropping on transistor which swith power to phone.
so at the end we get voltages below 3,7 volts which is not enough to power On phone
if you have on pinfinder output voltage below 3,7v- please modify your unibox
there must be diode removed and set shortcut.
Where is located this diode you can find in pin finder user manual in troubleshooting section
