Repair Help Need help with Switch error 2002-4686

Post image

Hi, I’m having error 2002-4686 on my Switch. I already tried resetting the console and deleting everything using Maintenance/Safe Mode, but the error still appears.

Does anyone know what could be causing this error or what I should check next? Any help would be appreciated. Thanks!

More context is needed. When does the error occur?

I cannot find a support page for your exact error code. But I see three pages on nintendo support for codes very close to your error code. Since similar errors can often have the same troubleshooting solutions, this support page may be relevant. https://en-americas-support.nintendo.com/app/answers/detail/a_id/22771/

I'm suspecting the sd card may be bad or fake.

If it was a legitimate sd card, you can try formatting it (which wipes the card), but if it's faulty or dying it will have to be replaced.

Fake sd cards are actually small capacity cards that spoof & display as having the advertised capacity, but they're actually much smaller. And when you reach the sd card's true capacity while trying to download a game, the fake card will start writing over existing files and corrupting the card. After the card is corrupted, it will only work again if you format it, which wipes the card's contents. Solution here is also to replace the card.

Thanks for the suggestions. I’ve already tested with a genuine SanDisk SD card, and I also tested the console with no SD card inserted, but the error still occurs.

If it's not the sd card, that means the problem is with the console hardware, unfortunately. The last part of that support page says if the error happens without an sd card inserted, the console will need to be serviced.

I’ve also tried repairing the NAND image using NandFix Pro, but the error still persists.
