Ipad mini model A1432 (1st Gen) missing pad FPC connector

Hi Everybody,

I have an iPad mini model A1432 (1st Gen) and when I was removing the fpc connector due to a broken pin, one of the pads came off. What number pad is this and what component does this pad link to? I was doing continuity tests on the piece of copper I see on the pad that was lifted and so far it doesn’t look like it’s the GND pad. Would this be the J1700 chip I see on the other schematic for the iPad mini 2?

I am not sure where the 1 position starts on this FPC connector.

I included a picture of the board that I am asking about.
