To reassemble your device, place a new metal piece where old one was and solder it to the motherboard in the four holes on the opposite side of the motherboard.

It is impossible to unmount the old damaged USB-Interface this way. Beside the four solder-points ist is also soldered to 5 extremely small points on the motherboards opposite side. These are SMD-mounted contacts and in my case trying to unsolder them damaged the motherbords layout.
I was able to desolder it with a hot air rework station + soldering iron without damaging the pcb then using a wick cut at an angle + the heat gun to clean the mounting holes you must clean then fully so the new part will mount flush.
Also take care with resoldering the new connector not to bridge the pins on the usb port.
what is the model of USB connector here? I would like to buy in advance before opening
These instructions are really incomplete. In addition to the 4 through-hole points mentioned, there are also 2 large ground pads under the connector, and 7 tiny surface-mount pins on the back. Removing this port pretty much requires low-temp (chip-quick) solder or a hot-air rework station. Soldering it back on with only an iron proved quite difficult - hot-air rework station highly recommended. This took me about an hour, and I’ve been soldering (hobby mostly) for the better part of 30 years.
Also, there’s no reason to remove the battery to change the charging port. The motherboard can be removed without removing the battery. And really, the cameras should be disconnected too, rather than leaving them dangling by their ribbon cables.
