New 3DS C-Stick Problem

[Vor]

Hi. This morning my 3DS dropped in the toilet (lol). And now my Home menu is sliding like crazy. Based on the Nintendo Support Website initially I thought there is something wrong with my Circle Pad or Touch Screen but I play most game with no error so I doubt it. I realize the C-Stick is the problem when I play Resident Evil since that game is using the C-Stick and the camera is just spinning around.

I want to ask if there is any way to repair my C stick (and to disable it if all methods fail). Don't suggest me to send it to Nintendo since I'm not living in NA.

Thanks.
