Do you have an oscilloscope or a logic analyzer?

and connect corresponding pins on the board:

Then you just insert the breakout board, connect pins to your board and you can extract.
Can i pm you?

ill send you better photos later.
show the other side right under the NAND, there should be an eMMC controller.

will this help me find the pins.
what about d0, d1, d2?

It's irrelevant if you don't have a scope.
