Few questions about chinese phones


HI infinty team
I have few questions about chinese phones....I cant get the answers of these questions...
1.How to find pinouts from these phones which r working without batteries..(using internal batteries)....When ever i press and hold power button on these phones they power on automatically and pinfinder cant b able to find pinouts...(Even i used pcb tx and rx)(mt6225)
2.How to change second imei on double sim mobiles.....
3.Sometimes i get some phones on which i find pinouts by pinfider easily but when i connect it to software for formattin or other operations which required test mode...The mobile goes in test mode but software still says connecting and at the end i got the error that phone is not in test mode...
So these r my questions and as i can see lots of threads with these questions and i m also facing these problems!

Find "POWER_B" test point at phone PCB and make it connected to GND during 2nd CPU pinout detection with PinFinder.

Sir,
Will it be Possible in Pinfinder software to findout ground pin also.
This will be great becoz in few sets The Battery required is of heavy current, so it is impossible to switch on The set(Completely) with Pinfinder Supply, It requires Battery & battery Ground Needed to be kept Common with that of Pinfinder.

Having Pinfinder finding Ground it will Greatly Help User to use Phone Battery itself for Forcing set in Test Mode, Formatting etc.

Thanks
Regards
Shubhanshu
