That must be a 2015 model. Attached is the location of the BGA connection.

Those came through OK but I can't make out the lettering on the chips.

Below or off to the side if the yellow block on the second image. Look up the chip ID's and post them here so we can look at the datasheets.

Actually this was answered in another thread and it looks like it checks out. The chip is right below the debug header.

I am pretty sure you are looking at the wrong chip, it is the flatter one.

That's what i think. after a lot of research i found 3 flash chips with this package. but none is more than 4mb! i will investigate the bare die next to it and get back to you with the results.
