The trick to charging ports that have to be resoldered is that you have to be very gentle and very patient. I have had success with my reworking stations heat gun and very small tweezers. The key is to make sure that you heat everything involved thoroughly so that you don't pull up the traces for the contacts. I am pretty sure that if it doesn't work when you get the new one in place you have damaged one of the traces. The only thing I can recommend is to practice as much as possible with your soldering iron and get very comfortable with it. This will give you a "sixth sense" on when you can start separating the minuscule contacts from the traces. I know this isn't a YouTube video, but I hope it helps you to be more confident over time.
