Please, download latest PinFinder manual: http://www.infinity-box.biz/download..._PinFinder.pdf
Please, see page 19: Automatic pinout detection: Troubleshooting
I hope you can solve at least 99% of possible problems (especially with 8, 12, 14, 15 pins cables) with this instruction.

i have followed the manual and check everything,is ok. atleast i used the L12B cable to fix one china p910i this morning.

hello!

i guess this phone is not using Tx/Rx pins in system connector.
must be some test points on PCB

GOODNESS · 03-29-2008, 12:10

please how do i locate the testpoint on pcb

InfinityHelp · 03-29-2008, 15:30

hello!

easyer if you post PCB picture and someone will help you.
also is possible to find needed test points by multimeter, by measuring voltages on all PCB testpoints.
this way is quite tricky, because you must keep phone disassembled, but it still must be powered from battery

this the pcb.i hope u can help me

InfinityHelp · 03-29-2008, 19:57

hello!

as i can see there is huge test point area on your PCB.
one of them must be tx/rx.
lets wait if someone will share with us pinount or i can advice how to find pins by multimeter
