Cect V329 - cannot detect pin with Pin-finder

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:

Can somebody help?

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?

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.

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

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?
