Cect V329 - cannot detect pin with Pin-finder - GSM-Forum

loukandr · 10-16-2008, 20:20

I'm trying to detect pins with pin-finder in order to read rom but pinfinder continually fails to detect pins! It is a Chinese phone.

You can have a look of it here:

Why is this phone not recognised by pinfinder?

Hello,

Did you tried to find RX and TX at phone PCB ?

Did you tried to set \"Finder activation tries\" value to 15 or 20 ?

Do I have to open the phone to do this? I haven't done it before.

No, I didn't. Will it change something?

hello!

sometimes, if pinout can not be found, you must set "activation tries" to greater, then default value. for example from my experience: iFOE P168i Finder activation tries below 10 (i had 7) did not detect pinout

I tried every single method (even 20 activation tries) but it still fails.
Any other suggestion?

hello!

is this phone is based on MT62xx MCU ?
maybe it is spreadtrum or else?

When connecting to USB while phone is switched on, I choose webcam mode and PC recognises it as 6225. Thus, it must be MT62xx CPU.
I tried other CPUs in LPE as well just in case with no success.

hello!

in this case this means that this phone doesent hold tx/rx in system connector

So you mean that there is no way to detect pinout?

InfinityHelp · 10-22-2008, 15:44

hello!

you must disassemble phone and look for test points.
take open cable from pinifnder and solder all wires to those test points.
which colur goes to which test point- is not important.
attach battery, run pinout search again

Hello!
Which one is the open cable?

Is it the open circuit that you mean (it is not actually a cable) ?

How will I recognise test points when I open the phone?

Are there any photo instructions or more details regarding this procedure somewhere?

InfinityHelp · 10-22-2008, 21:53

hello!

please post photo of your phone PCB, i will check if there is test points
