HTC One M7 Completely Dead, possible fix

HTC One M7 ( PN0731).

Not sure what happened to it, but there is no charge, no connect nothing through USB, no Boot, not even a little red light when plugged in. No JTAG, since no power to the board it seems.

Scratching my head to figure out why, cant come up with any reason for such a complete failure. So examined it with microscope.

Found one component that might be the problem.

Zooming in you can see that there is an IC that is cracked

What I'm looking for is help with 3 things:

1. Do you think this is the problem?

2. What is this component? It has an code (PAY 328), but I have no idea what that symbol in the top right corner is, so no idea how to look it up.

3. If not that, any ideas? I'm mostly concerned about data recovery, not making the device work again, so if anyone has ISP pinouts that might be a way to go
