hello!

lets start from basic: before searching pinout you must do 3 easy steps:

1. Make sure that this is mt62xx MCU based phone.
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 MT62xx.
Now activate Silent mode in phone by pressing and holding "#".

2. Count number of pins in system connector. After this is done-
pick correspondent cable. For example if you counted 2x6 pins- it is in total 12
so no point to put L14D cable instead of correct one, L12B.

3. Select cable type, connect power crocodiles in the place of battery.
push "Power On!" in software. Now phone is powered with pinfinder power (pinfinder RED LED is On) .
Try to switch phone On. This is main rule for success pinout search.
(Phone must turn ON or at least blink)

if it does not turn On- no point to search for pinouts. you will not find it.
Start from modifying your main infinity box to deliver more power to pinfinder.
There is one diode which must be removed and shortcutted.
Open Pinfinder User Manual on Trubleshooting section and see in pictures how this must be done.

after you get phone powered- you are ready to find phone pinout.
press and Hold phone power button and start search.
