I have a problem with my ESP-12 board. I can't get the solder to stick on the GPIO2 port because the metal thing that were on the port has fallen of. Are there any fix to this? I known the GPIO2 port is connected to the LED, so maybe there is a chance I can remove the LED and use its port as GPIO2.

But yes, best thing to do is to scrape off the protective coating of the trace that was connected to the GPIO2 pad and/or the LED and solder to the trace/LED directly.
Don't use too much heat and keep the soldering time as short as possible, to avoid additional damage.
