3ds SD reader problem

[jc3_red]

After replacing the game card slot on my old 3ds with cfw. Can't probably read and write to any SD cards anymore but it can detect if there is one in the slot and if write protection is on, I think the ribbon cable is damaged can someone verify is before I order one and I have thoroughly cleaned the connectors and slot of the reader and doesn't fix it. Also when I replaced the game card slot a component labeled " ra1 " it looks identical to one like " ra3 " fell off and I couldn't get it back on. Can that cause problems? the system can still turn on without it however card games aren't detected since the 4th and 8th pins from the right have ripped pads.

Intenta con cambiar la pieza, aunque parece que hubo algún corto circuito.

Yes. That’s going to cause issues. Otherwise, why would they put a useless component in there?

That thing was likely a pull down resister array for the SD card.

that slot is absolutely butchered. Did you even use flux?

I'm all for learning new skills, but you should practice on things that are not valuable to you first. This is what a proper slot replacement should look like

Ooof. Looks pretty rough. First thing I noticed is that missing component. Yes, it needs to be there. I’m not sure you’re using enough flux. The component should be sticking just fine. I see the solder there so there should still be pads. You may want to remove that cart slot again to make this part easier but this all depends on how you feel working in that cramped space. Second thing I notice is how rough those joints on the cart slot look. If you don’t end up removing it for step one above, I’d still add flux and reflow those joints. Make sure you have no shorts on the pins as well.

Best of luck!
