I changed the charging port with a new one. Still doesn't work. What is the U2 IC?

by

The U2 IC is a chip on the mainboard.

Understood. Path to follow then: do I just change the U2 IC or do I need to change the entire logic board? And if I do just change the chip, what specific tools will I need?

There can be a lot of things, ex. U2 IC, charging fuse, charging port, etc. Try to replace the charging port. If that doesn't work, you probably fried the U2 IC. That needs a lot of microsoldering experience to fix.
