Open up your 3DS, give a good hard look at the size of the solder pads, then practice on stuff with similar size. Keep doing that until you're 100% sure you can attach a wire securely without lifting the pad underneath (that happens if you spend too much time with the tip on the pad).
paste or liquid? im not really sure about this, I just saw that there are two types upon searching on amazon.
I'm not sure. I think that's up to preference.
I actually live in in the UAE, but that's cheap, really cheap. Anyways, which place?
Greenhills shopping center. He has a videogame repair shop over there. Yes, I meant shipping overseas because you live so far.
I personally prefer paste, you'll also probably want a desoldering pump/bulb/wick if you plan on soldering more. Good thing to remember with solder is that less is more, you don't need a ton to make good contact. I usually just put a tiny bit on the pad I'm soldering to, then I tin my wire and then use the iron to create contact between the pad and the tinned wire.
