Flash Recovery

Hey!
After a short discussion on reddit a user kindly forwarded me to this forum.
I crushed my USB stick after a bycicle crash. The chip has a small crack and starts to overheat as soon as I plug it into a USB.
Even if I'm not very confident to recover any data successfully, I'm just getting curious how to perfom a pinout on such a chip. I own a beginner SMD station and just started with SMD in general.
So there are a couple of questions:
1. Is there any specific term for this type of piggyback / monolithic all-in-one device? First, I was pretty sure I just found the USB-Male adapter. Persons on reddit confirmed that this is a kind of all-in-one-design, with the PCB directly on the chip.
2. Considering the overheating issue: Is this an clear indication that the chip is garbage or could it be that "just" the pcb/controller is broken?
3. Considering the process of pinning-out: How do I proceed? Should I remove the USB connector and restore the blank BGA under hot air?
4. I tried to google the specification on the chip; however I had no luck, what are good resources. Are there any other resources to identify the chip?

You *could* take it to a professional, but from the picture, it seems it is dead. Or after hearing the price of the recovery, you will decide the chip is dead.

If chip heats after connection usually it means recovery not possible (internal short or broken crystal inside).

Ouch
These small USB 3.0 UFD's look more like a MicroSD card inside...

Speaking of pain, I hope there were no serious personal injuries.

USB can recognize chip, and you can ask some expertise for advice or look through some related books.
