I was attempting a Hard mod on my Old 3ds because I bricked it a while ago and found out that I could fix it. I tried to heat the soldering points up to put a little solder on them, but the solder didn't stick to the point. I loaded it with flux and tried again, but it didn't work again. I tried over and over and over. They never ended up sticking. So after I was done I looked at the points and saw they looked like this. (Image Attached) I just want to know if I did destroy them, how to avoid it next time soldering, and if I could fix this.
