Is this a trick question?

so drive not working probably.
what are the 5 rectangular traces in the middle? some sort of signal interference mitigation or something?
looks like you may need to find a donor and use the 30 pads up top to find nand pinout. whats the drive?

I think something is fubar w/ the controller, the 3.3v rail isn't outputting the proper voltage.. I'll check the passive components tomorrow...

I think your pinout is right. Pad with 5V is cut out from two vias on the bottom from it. I guess it is the reason why you can't power up device.

it is either cut, or there is still some black coating left on there where laser missed.
