Hardware Shoulder button replacement?

[Sonansune]

I know it's possible to replace the o3ds shoulder button without soldering skills....
what about 2ds, n3dsxl and elder dsi

my 2ds's L button won't bounce back....
and dsi R button is dead....

Have you tried opening the 2ds? I think it's just a flex cable. As for the dsi im pretty sure its soldered onto the board. Ill check right now.

so 2ds, yes.
dsi, no?

Just checked my dsi and i see no traces of shoulder buttons on the motherboard. So yes its fixable by replacing the flex cable
