tushmanluuu, you only measure the outside contacts. You should expect to get at 4.6 V or better on there.
Not sure if this is the jumper diagram you were looking for.
Here is the diagram for which connector does what:
If it is not charging, check the USB power fuses and the USB power IC (that can only be done through either reballing or replacing the BGA IC)
考えを変えさせてください。
