A1502 Late 2013 MacBook Pro will not boot, one exception
Solution 1:
Good news, after a couple of months I FINALLY figured out the problem. After watching a Louis Rossmann video, I saw something about jtag connectors. I removed the jtag connector and the fans now spin. Along with that, it says the battery is low on the screen.
I'm assuming something at apple was able to turn it on. But now without the jtag connector it actually is working.
