Gaming (DSi Hardware) How to fix/replace an R button

[SwaGoat]

So,an old DSi I own has an unresponsive R shoulder button,but it seems to be broken since it doesn't even make a click sound.
From the inside,it looks a bit of rusty,if that helps by any means.
The only way I have to replace it is by replacing both the sdcard reader and the R button,but the shop I found this from,doesn't offer a service so as to install it for me (as I'm a newbie)
If I had to just replace a single part,I guess it would've been easy,but it seems that the sdcard reader needs a ribbon cable to be connected to somewhere.Does that connection require soldering?
If not,is it easy to apply?

Unironicly, I have the same issue. First try disassembling the R button, and clean it with a cleaning supply. If it still doesn't work, then it's time to replace the ribbon cable. And no, no soldering tools are required.

Just buy a new ribbon on aliexpress, reserve about 40mins and a problem will be gone.

Yea, same here. I still need to order a ribbon cable.

I used can air for a bilons of times and wasted few hours on cleaning the buttons, then in act of desperation I have bought new ribbon cable, and that was the best decision I have made.

How do you replace the ribbon cable?
By the way,this happened after I opened it in order to clean it,but I messed up a lot as it seems.
The volume can't be controlled (it's not bad quality,it's just annoying to have it that loud) and the L button started not working too.
Guess I shouldn't mess with that..
