Chosen Solution

So I recently fix my 3Ds XL for my little brother and he dropped it a month after. So after I opened it up and did a System check I found the speaker wire that were connected to the speaker ribbon are ripped out. Is there any way I could fix this by soldering them back together

Hi! You can totally solder that back on there. You can have a really good look at this picture to kindda see what goes where. However that ribbon looks beaten up to me, I’d replace that entirely.
